The county has an average altitude of 1,200 metres, with a low point of 640 meters at the intersection of the Qingshui River and the Hutou River , and a high point of 3,058 metres at Mount Wutai . Wutai County is divided into 5 towns , 11 townships , and 1 county resident's office. The county government

244-545: A continental monsoon climate, and is rather arid. Average January temperatures are below 0 °C, while average July temperatures are around 21–26 °C. Winters are long, dry, and cold, while summer is warm and humid. Spring is extremely dry and prone to dust storms. Shanxi is one of the sunniest parts of China; early summer heat waves are common. Annual precipitation averages around 350 to 700 millimetres (14 to 28 in), with 60% of it concentrated between June and August. Major cities: The outline of Shanxi's territory

366-609: A staple food in many parts of the world, with the total production of maize surpassing that of wheat and rice . Much maize is used for animal feed , whether as grain or as the whole plant, which can either be baled or made into the more palatable silage . Sugar-rich varieties called sweet corn are grown for human consumption, while field corn varieties are used for animal feed, for uses such as cornmeal or masa , corn starch , corn syrup , pressing into corn oil , alcoholic beverages like bourbon whiskey , and as chemical feedstocks including ethanol and other biofuels . Maize

488-612: A 36.4% increase from 2017. Major agricultural products in the county include corn , wheat , millet , and beans . Major industries in the county include coal mining , magnesium alloys , and power generation . As of 2018, the county had 5,253 pre-school students, 14,954 primary school students, 9,076 junior high students, 4,512 standard secondary school students, and 1,998 vocational secondary school students. That year, Wutai County had 21 kindergartens, 28 primary schools, 24 standard junior high schools, 3 standard secondary schools, and 1 vocational secondary school. The county

610-551: A center for trade and banking. The " Shanxi merchants " were once synonymous with wealth. The well-preserved city and UNESCO World Heritage Site Pingyao shows many signs of its economic importance during the Qing dynasty. With the collapse of the Qing dynasty , Shanxi became part of the newly established Republic of China . From 1911 to 1949, during the period of the Republic of China's period of rule over Mainland China , Shanxi

732-814: A conventional breeding program to provide optimized strains. The program began in the 1980s. Hybrid seeds are distributed in Africa by its Drought Tolerant Maize for Africa project. Tropical landraces remain an important and underused source of resistance alleles – both those for disease and for herbivores . Such alleles can then be introgressed into productive varieties. Rare alleles for this purpose were discovered by Dao and Sood, both in 2014. In 2018, Zerka Rashid of CIMMYT used its association mapping panel, developed for tropical drought tolerance traits. to find new genomic regions providing sorghum downy mildew resistance , and to further characterize known differentially methylated regions . Genetically modified maize

854-403: A corn head (with points and snap rolls instead of a reel) does not cut the stalk; it simply pulls the stalk down. The stalk continues downward and is crumpled into a mangled pile on the ground, where it usually is left to become organic matter for the soil . The ear of maize is too large to pass between slots in a plate as the snap rolls pull the stalk away, leaving only the ear and husk to enter

976-607: A distinct language from Mandarin and its geographical range covers most of Shanxi. Both Jin and Mandarin are spoken in Shanxi. Shanxi is a leading producer of coal in China , possessing roughly a third of China's total coal deposits. Nevertheless, Shanxi's GDP per capita remains below the national average. The province hosts the Taiyuan Satellite Launch Center . The province is also known for having by far

1098-408: A large cob. Yellow maizes derive their color from carotenoids ; red maizes are colored by anthocyanins and phlobaphenes ; and orange and green varieties may contain combinations of these pigments. Maize has short-day photoperiodism , meaning that it requires nights of a certain length to flower. Flowering further requires enough warm days above 10 °C (50 °F). The control of flowering

1220-571: A large, fortified prison complex filled with Communist prisoners. In a final act of desperation, Liang set fire to the prison and committed suicide as the entire compound burned to the ground. Soon after the Chinese Communist Revolution , Mao Zedong assigned Kang Sheng to carry out land reform in Shanxi. Kang encouraged the populace to have numerous farmers from a variety of socioeconomic backgrounds denounced as "landlords," beaten, arrested, and executed. In some areas of

1342-436: A major part of Shanxi's economy. Shanxi possesses 260 billion metric tons of known coal deposits, about a third of China's total. As a result, Shanxi is a leading producer of coal in China and has more coal companies than any other province, with an annual production exceeding 300 million metric tonnes. The Datong ( 大同 ), Ningwu ( 宁武 ), Xishan ( 西山 ), Hedong ( 河东 ), Qinshui ( 沁水 ), and Huoxi ( 霍西 ) coalfields are some of

1464-499: A measure of protection against a wide range of pests. Because of its shallow roots, maize is susceptible to droughts, intolerant of nutrient-deficient soils, and prone to being uprooted by severe winds. Maize is diploid with 20 chromosomes . 83% of allelic variation within the genome derives from its teosinte ancestors, primarily due to the freedom of Zea species to outcross . Barbara McClintock used maize to validate her transposon theory of "jumping genes", for which she won

1586-474: A modern curriculum and infrastructure of Chinese medicine achieved limited success, but much of the teaching and publication that this school of medicine produced was limited to the area around Taiyuan: by 1949 three of the seven government-run hospitals were in the city. In 1934 the province produced a ten-year-plan that envisaged employing a hygiene worker in every village, but the Japanese invasion in 1937 and

1708-638: A place but a condition, a savage rather than a civilized grain". International groups such as the Centre for Agriculture and Bioscience International consider maize the preferred common name. The word maize is used by the UN's Food and Agriculture Organization , and in the names of the International Maize and Wheat Improvement Center of Mexico, the Indian Institute of Maize Research,

1830-601: A plant that uses C 4 carbon fixation , maize is a considerably more water-efficient crop than plants that use C 3 carbon fixation such as alfalfa and soybeans . Maize is most sensitive to drought at the time of silk emergence, when the flowers are ready for pollination. In the United States, a good harvest was traditionally predicted if the maize was "knee-high by the Fourth of July ", although modern hybrids generally exceed this growth rate. Maize used for silage

1952-604: A primary-school education and taught domestic skills. After National Revolutionary Army military victories in the 1925 generated great interest in Shanxi for the Kuomintang 's ideology, including women's rights , Yan allowed girls to enroll in middle school and college, where they promptly formed a women's association. Yan attempted to eradicate the custom of foot binding , threatening to sentence men who married women with bound feet, and mothers who bound their daughters' feet, to hard labor in state-run factories. He discouraged

2074-563: A relatively high level of public order and security. Yan went to great lengths to eradicate social traditions which he considered antiquated. He insisted that all men in Shanxi abandon their Qing-era queues, giving police instructions to clip off the queues of anyone still wearing them. In one instance, Yan lured people into theatres in order to have his police systematically cut the hair of the audience. He attempted to combat widespread female illiteracy by creating in each district at least one vocational school in which peasant girls could be given

2196-555: A small force of 6,000 men to hold off the entire Japanese army. A representative of the Japanese Army, speaking of the final defense of Taiyuan , said that "nowhere in China have the Chinese fought so obstinately". The Japanese suffered 30,000 dead and an equal number wounded in their effort to take northern Shanxi. A Japanese study found that the battles of Pingxingguan, Xinkou, and Taiyuan were responsible for over half of all

2318-537: A three-way split into the states of Han , Zhao , and Wei in 403 BC, a traditional date sometimes taken as the start of the Warring States period ( c.  473  – 221 BC). By 221 BC, all of these states had fallen to the state of Qin , which established the Qin dynasty (221–206 BC). The Han dynasty (206 BC – AD 220) ruled Shanxi as the province of Bingzhou . During

2440-539: A width of 385 km (239 mi) from east to west, with a total area of 156,700 km (60,500 sq mi), accounting for 1.6% of the country's total area. Shanxi is divided into eleven prefecture-level divisions : all prefecture-level cities : The 11 prefecture-level cities of Shanxi are subdivided into 118 county-level divisions (23 districts , 11 county-level cities , and 84 counties ). Those are in turn divided into 1388 township-level divisions (561 towns , 634 townships , and 193 subdistricts ). At

2684-428: Is a parallelogram that runs from southwest to northeast. It is a typical mountain plateau widely covered by loess . The terrain is high in the northeast and low in the southwest. The interior of the plateau is undulating, the valleys are vertical and horizontal, and the types of landforms are complex and diverse. There are mountains, hills, terraces, plains, and rivers. The area of mountains and hills accounts for 80.1% of

2806-477: Is a problem in Asia. Some fungal diseases of maize produce potentially dangerous mycotoxins such as aflatoxin . In the United States, major diseases include tar spot , bacterial leaf streak , gray leaf spot , northern corn leaf blight, and Goss's wilt ; in 2022, the most damaging disease was tar spot, which caused losses of 116.8 million bushels . Maize sustains a billion dollars' worth of losses annually in

2928-564: Is also home to the Wutai County Resident Office ( 五台县居民办事处 ), which functions as a township-level division of the county. Of the county's 307,200 permanent residents, 126,200 (41.08%) lived in urban areas as of 2018, whereas the remaining 181,000 (58.92%) lived in rural areas. Wutai County has a per capita disposable income of 12,838 Yuan , with urban residents averaging 26,643 Yuan and rural residents averaging 6,787 Yuan. The Engel Coefficient for urban households

3050-408: Is composed of transposons , contains 32,540 genes. Much of it has been duplicated and reshuffled by helitrons , a group of transposable elements within maize's DNA. Maize breeding in prehistory resulted in large plants producing large ears. Modern breeding began with individuals who selected highly productive varieties in their fields and then sold seed to other farmers. James L. Reid was one of

3172-537: Is cultivated throughout the world; a greater weight of maize is produced each year than any other grain. In 2020, world production was 1.1 billion tonnes. It is afflicted by many pests and diseases ; two major insect pests, European corn borer and corn rootworms , have each caused annual losses of a billion dollars in the US. Modern plant breeding has greatly increased output and qualities such as nutrition, drought tolerance, and tolerance of pests and diseases. Much maize

3294-440: Is from north to south and from basin to high mountain. The annual precipitation in the whole province is between 358 and 621 mm, and the seasonal distribution is uneven. In June–August, the precipitation is relatively concentrated, accounting for about 60% of the annual precipitation, and the precipitation distribution in the province is greatly affected by the terrain. The province has a length of 682 km (424 mi) and

3416-414: Is harvested while the plant is green and the fruit immature. Sweet corn is harvested in the "milk stage", after pollination but before starch has formed, between late summer and early to mid-autumn. Field maize is left in the field until very late in the autumn to thoroughly dry the grain, and may, in fact, sometimes not be harvested until winter or even early spring. The importance of sufficient soil moisture

3538-519: Is home to a number of cultural sights, including a number of historic temples. Major sights include Mount Wutai , Foguang Temple , Zunsheng Temple , Nanchan Temple , Xiantong Temple , Guangji Temple  [ zh ] , Yanqing Temple , Shuxiang Temple , Jinge Temple , Bishan Temple , Yuanzhao Temple , Nanshan Temple  [ zh ] , Pusading , Tayuan Temple , the Former Residence of Xu Xiangqian  [ zh ] , and

3660-533: Is now genetically modified . As a food, maize is used to make a wide variety of dishes including Mexican tortillas and tamales , Italian polenta , and American hominy grits . Maize protein is low in some essential amino acids , and the niacin it contains only becomes available if freed by alkali treatment . In Mesoamerica, maize is deified as a maize god and depicted in sculptures. Maize requires human intervention for it to propagate. The kernels of its naturally-propagating teosinte ancestor fall off

3782-413: Is possible that decades of Yan's socialist indoctrination may have prepared the people of Shanxi for Communist rule. After the death of Mao, the experiment was discontinued, and most peasants reverted to private farming under post-Maoist economic reforms . Shanxi is located on a plateau made up of higher ground to the east ( Taihang Mountains ) and the west ( Lüliang Mountains ) and a series of valleys in

4026-468: Is set genetically; the physiological mechanism involves the phytochrome system. Tropical cultivars can be problematic if grown in higher latitudes, as the longer days can make the plants grow tall instead of setting seed before winter comes. On the other hand, growing tall rapidly could be convenient for producing biofuel. Immature maize shoots accumulate a powerful antibiotic substance, 2,4-dihydroxy-7-methoxy-1,4-benzoxazin-3-one ( DIMBOA ), which provides

4148-560: Is shown in many parts of Africa, where periodic drought regularly causes maize crop failure and consequent famine . Although it is grown mainly in wet, hot climates, it can thrive in cold, hot, dry or wet conditions, meaning that it is an extremely versatile crop. Maize was planted by the Native Americans in small hills of soil, in the polyculture system called the Three Sisters . Maize provided support for beans ;

4270-557: Is the domesticated variant of the four species of teosintes , which are its crop wild relatives . The teosinte origin theory was proposed by the Russian botanist Nikolai Ivanovich Vavilov in 1931, and the American Nobel Prize -winner George Beadle in 1932. The two plants have dissimilar appearance, maize having a single tall stalk with multiple leaves and teosinte being a short, bushy plant. The difference between

4392-405: Is the leaf most closely associated with a particular developing ear. This leaf and those above it contribute over three quarters of the carbohydrate ( starch ) that fills the grain. The grains are usually yellow or white in modern varieties; other varieties have orange, red, brown, blue , purple , or black grains. They are arranged in 8 to 32 rows around the cob; there can be up to 1200 grains on

4514-612: The Balsas River valley in Mexico's southwestern highlands, as the crop wild relative genetically most similar to modern maize. The middle part of the short Balsas River valley is the likely location of early domestication. Stone milling tools with maize residue have been found in an 8,700 year old layer of deposits in a cave not far from Iguala, Guerrero . Doebley and colleagues showed in 2002 that maize had been domesticated only once, about 9,000 years ago, and then spread throughout

4758-653: The Khitans destroyed Later Jin, the third. Finally, when the fifth of the Five Dynasties ( Later Zhou ) emerged, the jiedushi of Hedong at the time, Liu Chong , rebelled and established an independent state called Northern Han , one of the Ten Kingdoms, in what is now northern and central Shanxi. Shi Jingtang , founder of the Later Jin , the third of the Five Dynasties, ceded a piece of northern China to

4880-658: The Khitans in return for military assistance. This territory, called the Sixteen Prefectures of Yanyun , included a part of northern Shanxi. The ceded territory became a major problem for the Song dynasty's defense against the Khitans for the next 100 years because it lay south of the Great Wall . The later Zhou , the last dynasty of the Five Dynasties period was founded by Guo Wei , a Han Chinese, who served as

5002-769: The Ming dynasty (1368–1644) which were of the same land area and borders as the previous Hedong Commandery of the Tang dynasty. During the Qing dynasty (1644–1911), Shanxi extended north beyond the Great Wall to include parts of Inner Mongolia , including what is now the city of Hohhot , and overlapped with the jurisdiction of the Eight Banners and the Guihua Tümed banner in that area. For centuries, Shanxi served as

Later the Southern Song dynasty abandoned all of North China , including Shanxi, to the Jurchen Jin dynasty (1115–1234) in 1127 after the Jingkang Incident of the Jin-Song wars . The Mongol Yuan dynasty administered China into provinces but did not establish Shanxi as a province. Shanxi only gained its present name and approximate borders during

5246-483: The Three Sisters polyculture . The leafy stalk of the plant gives rise to male inflorescences or tassels which produce pollen , and female inflorescences called ears . The ears yield grain, known as kernels or seeds. In modern commercial varieties, these are usually yellow or white; other varieties can be of many colors. Maize relies on humans for its propagation. Since the Columbian exchange , it has become

5368-607: The 1983 Nobel Prize in Physiology or Medicine . Maize remains an important model organism for genetics and developmental biology . The MADS-box motif is involved in the development of maize flowers. The Maize Genetics and Genomics Database is funded by the US Department of Agriculture to support maize research. The International Maize and Wheat Improvement Center maintains a large collection of maize accessions tested and cataloged for insect resistance. In 2005,

5490-662: The Americas. Maize pollen dated to 7,300 years ago from San Andres, Tabasco has been found on the Caribbean coast. A primitive corn was being grown in southern Mexico, Central America, and northern South America 7,000 years ago. Archaeological remains of early maize ears, found at Guila Naquitz Cave in the Oaxaca Valley , are roughly 6,250 years old; the oldest ears from caves near Tehuacan , Puebla, are 5,450 years old. Around 4,500 years ago, maize began to spread to

5612-717: The Assistant Military Commissioner at the court of the Later Han which was ruled by Shatuo Turks . He founded his dynasty by launching a military coup against the Turkic Later Han Emperor however, his newly established dynasty was short-lived and was conquered by the Song dynasty in 960. In the early years of the Northern Song dynasty (960–1127), the sixteen ceded prefectures continued to be an area of contention between

5734-479: The B-vitamin niacin , the lack of which caused pellagra . Once alkali processing and dietary variety were understood and applied, pellagra disappeared in the developed world. The development of high- lysine maize and the promotion of a more balanced diet have contributed to its demise. Pellagra still exists in food-poor areas and refugee camps where people survive on donated maize. The name maize derives from

5856-528: The Eighth Route Army and continued to advance towards Yan's capital. The lack of attention directed at their forces gave the Communists time to recruit and propagandize among the local peasant populations (who generally welcomed Communist forces enthusiastically) and to organize a network of militia units, local guerrilla bands and popular mass organizations. Genuine Communist efforts to resist

5978-489: The Japanese "special forces" under Yan totaled 15,000 troops, plus an officer corps that was distributed throughout Yan's army. These numbers were reduced to 10,000 after serious American efforts to repatriate the Japanese were partially successful. Yan's Japanese army was instrumental in helping him to retain control of most of northern Shanxi during much of the subsequent Chinese Civil War , but by 1949 casualties had reduced

6100-418: The Japanese gave them the authority to carry out sweeping and radical social and economic reforms, mostly related to land and wealth redistribution, which they defended by labeling those who resisted as Hanjian . Communist efforts to resist the Japanese also won over Shanxi's small population of patriotic intellectuals, and conservative fears of resisting them effectively gave the Communists unlimited access to

6222-465: The Japanese into his service in the manner that he did, he retained both the extensive industrial complex around Taiyuan and virtually all of the managerial and technical personnel employed by the Japanese to run it. Yan was so successful in convincing surrendered Japanese to work for him that, as word spread to other areas of north China, Japanese soldiers from those areas began to converge on Taiyuan to serve his government and army. At its greatest strength

6344-646: The Japanese. During the Battle of Xinkou , the Chinese defenders resisted the efforts of Japan's elite Itakagi Division for over a month, despite Japanese advantages in artillery and air support. By the end of October 1937, Japan's losses were four times greater than those suffered at Pingxingguan, and the Itakagi Division was close to defeat. Contemporary Communist accounts called the battle "the most fierce in North China", while Japanese accounts called

The name maize is preferred in formal, scientific, and international usage as a common name because it refers specifically to this one grain, unlike corn , which has a complex variety of meanings that vary by context and geographic region. Most countries primarily use

6832-471: The Tang dynasty and after, present day Shanxi was called Hédōng ( 河東 ), or "east of the (Yellow) river". Empress Wu Zetian , one of China's only female rulers, was born in Shanxi in 624. During the first part of the Five Dynasties and Ten Kingdoms period (907–960), Shanxi supplied rulers of three of the Five Dynasties. Among the Ten Kingdoms, it was the only one located in northern China. Shanxi

6954-562: The US National Science Foundation , Department of Agriculture, and the Department of Energy formed a consortium to sequence the maize genome . The resulting DNA sequence data was deposited immediately into GenBank , a public repository for genome-sequence data. Sequencing of the maize genome was completed in 2008. In 2009, the consortium published results of its sequencing effort. The genome, 85% of which

Highly unusual in China at the time, the school had a four-year curriculum and included courses in both Chinese and Western Medicine. The main skills that Yan hoped physicians trained at

7442-439: The area around Taiyuan was a major national producer of coal, iron, chemicals, and munitions. Yan was able to protect the province from his rivals for the period of his rule partially due to his building of an arsenal in Taiyuan that, for the entire period of his administration, remained the only center in China capable of producing field artillery. Yan's army was successful in eradicating banditry in Shanxi, allowing him to maintain

7564-482: The battle a "stalemate". In an effort to save their forces at Xinkou, Japanese forces began an effort to occupy Shanxi from a second direction, in the east. After a week of fighting, Japanese forces captured the strategic Niangzi Pass , opening the way to capturing Taiyuan. Communist guerrilla tactics were ineffective in slowing down the Japanese advance. The defenders at Xinkou, realizing that they were in danger of being outflanked, withdrew southward, past Taiyuan, leaving

7686-418: The beans provided nitrogen derived from nitrogen-fixing rhizobia bacteria which live on the roots of beans and other legumes ; and squashes provided ground cover to stop weeds and inhibit evaporation by providing shade over the soil. Sweet corn, harvested earlier than maize grown for grain, grows to maturity in a period of from 60 to 100 days according to variety. An extended sweet corn harvest, picked at

It was cultivated in Spain just a few decades after Columbus's voyages and then spread to Italy, West Africa and elsewhere. By the 17th century, it was a common peasant food in Southern Europe. By the 18th century, it was the chief food of the southern French and Italian peasantry, especially as polenta in Italy. When maize

7930-420: The casualties suffered by the Japanese army in North China. Yan himself was forced to withdraw after having 90% of his army destroyed, including a large force of reinforcements sent into Shanxi by the central government. Throughout 1937, numerous high-ranking Communist leaders, including Mao Zedong , lavished praise on Yan for waging an uncompromising campaign of resistance against the Japanese. Possibly because of

The Great Wall of China forms most of the northern border with Inner Mongolia . The Zhongtiao Mountains run along part of the southern border and separate Shanxi from the east–west part of the Yellow River. Mount Hua is to the southwest. The Yellow River forms

8174-510: The city's walls, initiating bloody street-to-street fighting for control of the city. At 10:00 am, April 22, the Taiyuan Campaign ended with the Communists in complete control of Shanxi. Total Nationalist casualties amounted to all 145,000 defenders, many of whom were taken as POWs. The Communists lost 45,000 men and an unknown number of civilian laborers they had drafted, all of whom were either killed or injured. The fall of Taiyuan

8296-577: The cob on their own, while those of domesticated maize do not. All maize arose from a single domestication in southern Mexico about 9,000 years ago. The oldest surviving maize types are those of the Mexican highlands. Maize spread from this region to the lowlands and over the Americas along two major paths. The centre of domestication was most likely the Balsas River valley of south-central Mexico. Maize reached highland Ecuador at least 8000 years ago. It reached lower Central America by 7600 years ago, and

8418-551: The commander of the Eighth Route Army active in Shanxi and was named the vice-commander of the Second War Zone, under Yan himself. Yan initially responded warmly to the re-entry of the arrival of Communist forces, and they were greeted with enthusiasm by Yan's officials and officers. Communist forces arrived in Shanxi just in time to help defeat a decisively more powerful Japanese force attempting to move through

8540-445: The defenders due to fears of being shot down by the advancing Communists. The People's Liberation Army , depending largely on their reinforcements of artillery, launched a major assault on April 20, 1949, and succeeded in taking all positions surrounding Taiyuan by April 22. A subsequent appeal to the defenders to surrender was refused. On the morning of April 22, 1949, the PLA bombarded Taiyuan with 1,300 pieces of artillery and breached

8662-425: The earliest and most successful, developing Reid's Yellow Dent in the 1860s. These early efforts were based on mass selection (a row of plants is grown from seeds of one parent), and the choosing of plants after pollination (which means that only the female parents are known). Later breeding efforts included ear to row selection (C. G. Hopkins c. 1896), hybrids made from selected inbred lines (G. H. Shull, 1909), and

8784-666: The end of 1936 Taiyuan had become a gathering point for anti-Japanese intellectuals from all over China. The Marco Polo Bridge Incident in July 1937 led the Imperial Japanese Armed Forces to invade China, and Shanxi was one of the first areas the Japanese attacked. When it became clear to Yan that his forces might not be successful in repelling the Imperial Japanese Army , he invited Communist military forces to re-enter Shanxi. Zhu De became

8906-548: The end of 2017, the total population of Shanxi is 37.02 million. The Governor of Shanxi is the highest-ranking official in the People's Government of Shanxi. However, in the province's dual party-government governing system, the Governor is subordinate to the provincial Communist Party Committee Secretary ( 中共山西省委书记 ), colloquially termed the "Shanxi Party Committee Secretary ". As is the case in almost all Chinese provinces,

9028-413: The entire ear is harvested, which requires a separate operation of a maize sheller to remove the kernels from the ear. Whole ears of maize were often stored in corn cribs , sufficient for some livestock feeding uses. Today corn cribs with whole ears, and corn binders, are less common because most modern farms harvest the grain from the field with a combine harvester and store it in bins . The combine with

9150-774: The expansion of the Inca Empire , maize was traded and transported as far south as 40° S in Melinquina, Lácar Department , Argentina, probably brought across the Andes from Chile. After the arrival of Europeans in 1492, Spanish settlers consumed maize, and explorers and traders carried it back to Europe . Spanish settlers much preferred wheat bread to maize. Maize flour could not be substituted for wheat for communion bread, since in Christian belief at that time only wheat could undergo transubstantiation and be transformed into

9272-663: The former base of the Chinese Communist Party and the People's Liberation Army. Taiyuan Satellite Launch Centre , one of China's three satellite launch centers, is located in the middle of Shanxi with China's largest stockpile of nuclear missiles . Many private corporations, in joint ventures with the state-owned mining corporations, have invested billions of dollars in the mining industry of Shanxi . Hong Kong billionaire Li Ka-shing made one of his largest investments ever in China in exploiting coal gas in Shanxi. Foreign investors include mining companies from Canada,

9394-451: The head of Yan's "Patriotic Sacrifice League", had fought for years against the Communists in Shanxi until he was finally trapped in the massively fortified city of Taiyuan. For six months Liang put up a fierce resistance, leading both Yan's remaining Republic of China Army forces and his thousands of Japanese mercenaries. When Communist troops finally broke into the city and began to occupy large sections of it, Liang barricaded himself inside

9516-462: The highest-ranked provincial officials, Jin Yinhuan , died in a car accident. Since Xi Jinping 's ascendancy to General Secretary of the Chinese Communist Party at the 18th Party Congress , numerous highly ranked officials in Shanxi have been placed under investigation for corruption-related offenses, including four incumbent members Bai Yun , Chen Chuanping , Du Shanxue , and Nie Chunyu of

9638-532: The highly successful double cross hybrids using four inbred lines ( D. F. Jones c. 1918, 1922). University-supported breeding programs were especially important in developing and introducing modern hybrids. Since the 1940s, the best strains of maize have been first-generation hybrids made from inbred strains that have been optimized for specific traits, such as yield, nutrition, drought, pest and disease tolerance. Both conventional cross-breeding and genetic engineering have succeeded in increasing output and reducing

9760-550: The history of the word corn in North America that "[t]o say the word corn is to plunge into the tragi-farcical mistranslations of language and history". Similar to the British usage, the Spanish referred to maize as panizo , a generic term for cereal grains, as did Italians with the term polenta . The British later referred to maize as Turkey wheat, Turkey corn, or Indian corn; Fussell comments that "they meant not

9882-517: The influence of solar radiation, monsoon circulation and geographical factors, Shanxi's climate has four distinct seasons, synchronous rain and heat, sufficient sunshine, significant climate difference between north and south, wide temperature difference between winter and summer, and large temperature difference between day and night. The annual average temperature in Shanxi Province is between 4.2 and 14.2 °C. The overall distribution trend

10004-587: The invasion of northern nomads in the Sixteen Kingdoms period (304–439), several regimes including the Later Zhao , Former Yan , Former Qin , and Later Yan continuously controlled Shanxi. They were followed by Northern Wei (386–534), a Xianbei kingdom, which had one of its earlier capitals at present-day Datong in northern Shanxi, and which went on to rule nearly all of northern China. The Tang dynasty (618–907) originated in Taiyuan. During

10126-528: The largest number of historic buildings among all Chinese provinces, by possessing over 70% of China's surviving buildings built during or predating the Song dynasty . Also notable are the Yungang Grottoes in Datong, which date back over 1500 years. In the Spring and Autumn period ( c.  770  – c.  481 BC ), the state of Jin was located in what is now Shanxi. It underwent

10248-419: The machinery. The combine separates the husk and the cob, keeping only the kernels. Drying is vital to prevent or at least reduce damage by mould fungi, which contaminate the grain with mycotoxins . Aspergillus and Fusarium spp. are the most common mycotoxin sources, and accordingly important in agriculture. If the moisture content of the harvested grain is too high, grain dryers are used to reduce

10370-413: The milk stage, can be arranged either by planting a selection of varieties which ripen earlier and later, or by planting different areas at fortnightly intervals. Maize harvested as a grain crop can be kept in the field a relatively long time, even months, after the crop is ready to harvest; it can be harvested and stored in the husk leaves if kept dry. Before World War II , most maize in North America

10492-427: The moisture content by blowing heated air through the grain. This can require large amounts of energy in the form of combustible gases ( propane or natural gas ) and electricity to power the blowers. Maize is widely cultivated throughout the world, and a greater weight of maize is produced each year than any other grain. In 2020, total world production was 1.16 billion tonnes , led by the United States with 31.0% of

10614-563: The most important in Shanxi. Shanxi also contains about 500 million tonnes of bauxite deposits, about a third of total Chinese bauxite reserves. Industry in Shanxi is centered around heavy industries such as coal and chemical production, power generation, and metal refining . As part of an effort to promote diversification in non-resource industries, since 2004, some local governments in Shanxi province have required that coal mining companies set aside funds for investing in non-coal business like agriculture and produce processing. In 2006,

10736-501: The mountains', a reference to its location west of the Taihang Mountains . Shanxi borders Hebei to the east, Henan to the south, Shaanxi to the west and Inner Mongolia to the north. Shanxi's terrain is characterised by a plateau bounded partly by mountain ranges. Shanxi's culture is largely dominated by the ethnic Han majority, who make up over 99% of its population. Jin Chinese is considered by some linguists to be

10858-501: The need for cropland, pesticides, water and fertilizer. There is conflicting evidence to support the hypothesis that maize yield potential has increased over the past few decades. This suggests that changes in yield potential are associated with leaf angle, lodging resistance, tolerance of high plant density, disease/pest tolerance, and other agronomic traits rather than increase of yield potential per individual plant. Certain varieties of maize have been bred to produce many ears; these are

10980-400: The new crop. The rise in maize cultivation 500 to 1,000 years ago in what is now the southeastern United States corresponded with a decline of freshwater mussels , which are very sensitive to environmental changes. Because it is cold-intolerant, in the temperate zones maize must be planted in the spring. Its root system is generally shallow, so the plant is dependent on soil moisture. As

11102-465: The north. In the United States, maize was first cultivated at several sites in New Mexico and Arizona about 4,100 years ago. During the first millennium AD, maize cultivation spread more widely in the areas north. In particular, the large-scale adoption of maize agriculture and consumption in eastern North America took place about A.D. 900. Native Americans cleared large forest and grassland areas for

11224-451: The number of Japanese soldiers under Yan's command to 3,000. The leader of the Japanese under Yan's command, Hosaku Imamura, committed suicide on the day that Taiyuan fell to Communist forces. Yan Xishan himself (along with most of the provincial treasury) was airlifted out of Taiyuan in March 1949. Shortly afterwards Republic of China Air Force planes stopped dropping food and supplies for

11346-760: The presence of Starlink genetically modified corn, which had been approved only for animal consumption. The maize genus Zea is relatively closely related to sorghum , both being in the PACMAD clade of Old World grasses, and much more distantly to rice and wheat , which are in the other major group of grasses, the BOP clade . It is closely related to Tripsacum , gamagrass. various grasses e.g. fescue , ryegrass Hordeum (barley) Triticum (wheat) Oryza (rice) Pennisetum (fountaingrasses) Sorghum (sorghum) Tripsacum (gamagrass) Zea mays (maize) other Zea species ( teosintes ) Maize

11468-484: The province as many as one in five residents were denounced as landlords, and his program was copied throughout the rest of the new People's Republic of China . Shanxi became the site of Mao's "model brigade" of Dazhai : a utopian communist scheme in Xiyang County that was supposed to be the model for all other peasants in China to emulate. If the people of Dazhai were especially suited for such an experiment, it

11590-464: The province. He has been viewed by Western biographers as a transitional figure who advocated using Western technology to protect Chinese traditions, while at the same time reforming older political, social and economic conditions in a way that paved the way for the radical changes that would occur after his rule. In 1918 there was an outbreak of bubonic plague in northern Shanxi that lasted for two months and killed 2,664 people. Yan's interactions with

11712-424: The provincial Communist Party Standing Committee. They were all removed from office around August 2014. The following were also removed from office: Thousands of Shanxi officials were disciplined during the anti-corruption campaign under Xi Jinping . This necessitated a scramble to find find suitable personnel for many vacated offices. In the aftermath of the 'political earthquake', party secretary Yuan Chunqing

11834-415: The provincial government established a policy of "subsidizing peasants by coal" which made this diversification a provincewide requirement and encouraged local governments to develop policies like subsidies and favorable tax treatment to further encourage mining companies to invest in non-coal business. There are countless military-related industries in Shanxi due to its geographic location and history as

11956-464: The provincial party secretary and Governor are not natives of Shanxi; rather, they are outsiders who are, in practice, appointed by the central party and government authorities. The province went through significant political instability since 2004, due largely to the number of scandals that have hit the province on labour safety, the environment, and the interconnected nature between the provincial political establishment and big coal companies. Yu Youjun

12078-420: The rural population. Subsequent atrocities committed by the Japanese in the effort to rid Shanxi of Communist guerrillas aroused the hatred of millions in the Shanxi countryside, causing the rural population to turn to the Communists for leadership against the Japanese. All of these factors explain how, within a year of re-entering Shanxi, the Communists were able to take control of most of Shanxi not firmly held by

12200-410: The school would learn were: a standardized system of diagnosis; sanitary science, including bacteriology ; surgical skills, including obstetrics ; and, the use of diagnostic instruments. Yan hoped that his support of the school would eventually lead to increased revenues in the domestic and international trade of Chinese drugs, improved public health , and improved public education . Yan's promotion of

12322-607: The severity of his losses in northern Shanxi, Yan abandoned a plan of defense based on positional warfare, and began to reform his army as a force capable of waging guerrilla warfare. After 1938 most of Yan's followers came to refer to his regime as a "guerrilla administration". After the surrender of Japan and the end of the Second World War , Yan Xishan was notable for his ability to recruit thousands of Japanese soldiers stationed in northwest Shanxi in 1945, including their commanding officers, into his army. By recruiting

12444-491: The source of the " baby corn " used as a vegetable in Asian cuisine . A fast-flowering variety named mini-maize was developed to aid scientific research, as multiple generations can be obtained in a single year. One strain called olotón has evolved a symbiotic relationship with nitrogen-fixing microbes, which provides the plant with 29%–82% of its nitrogen. The International Maize and Wheat Improvement Center (CIMMYT) operates

12566-415: The stalk. Maize is monoecious , with separate male and female flowers on the same plant. At the top of the stem is the tassel, an inflorescence of male flowers; their anthers release pollen, which is dispersed by wind . Like other pollen, it is an allergen , but most of it falls within a few meters of the tassel and the risk is largely restricted to farm workers. The female inflorescence, some way down

12688-425: The stem from the tassel, is first seen as a silk, a bundle of soft tubular hairs , one for the carpel in each female flower, which develops into a kernel (often called a seed. Botanically, as in all grasses, it is a fruit, fused with the seed coat to form a caryopsis ) when it is pollinated. A whole female inflorescence develops into an ear or corncob , enveloped by multiple leafy layers or husks. The ear leaf

12810-418: The strategic Pingxing Pass . The Battle of Pingxingguan was the largest battle won by the Communists against the Japanese. After the Japanese responded to this defeat by outflanking the defenders and moving towards Taiyuan , the Communists avoided decisive battles and mostly attempted to harass Japanese forces and sabotage Japanese lines of supply and communication. The Japanese suffered, but mostly ignored

12932-567: The subsequent civil war made it impossible to carry these plans out. Yan's generous support for the Research Association for the Improvement of Chinese Medicine generated a body of teaching and publication in modern Chinese medicine that became one of the foundations of the national institution of modern traditional Chinese medicine that was adopted in the 1950s. Yan invested in Shanxi's industrial infrastructure, and by 1949

13054-608: The term maize , and the name corn is used mainly in the United States and a handful of other English-speaking countries. In countries that primarily use the term maize , the word corn may denote any cereal crop, varying geographically with the local staple , such as wheat in England and oats in Scotland or Ireland. The usage of corn for maize started as a shortening of " Indian corn " in 18th-century North America. The historian of food Betty Fussell writes in an article on

13176-472: The total (table). China produced 22.4% of the global total. Many pests can affect maize growth and development, including invertebrates, weeds, and pathogens. Maize is susceptible to a large number of fungal, bacterial, and viral plant diseases . Those of economic importance include diseases of the leaf, smuts such as corn smut , ear rots and stalk rots. Northern corn leaf blight damages maize throughout its range, whereas banded leaf and sheath blight

13298-530: The total area of the province, and the area of Pingchuan and river valleys accounts for 19.9% of the total area. Most of the province's altitude is above 1,500 meters, and the highest point is the Yedoufeng, the main peak of Wutai Mountain , with an altitude of 3061.1 meters, which is the highest peak in northern China. Shanxi is located in the inland of the mid-latitude zone and belongs to the temperate continental monsoon climate in terms of climate type. Due to

13420-500: The two is largely controlled by differences in just two genes, called grassy tillers-1 ( gt1 , A0A317YEZ1 ) and teosinte branched-1 ( tb1 , Q93WI2 ). In the late 1930s, Paul Mangelsdorf suggested that domesticated maize was the result of a hybridization event between an unknown wild maize and a species of Tripsacum , a related genus; this has been refuted by modern genetic testing . In 2004, John Doebley identified Balsas teosinte, Zea mays subsp. parviglumis , native to

13542-500: The use of the traditional lunar calendar and encouraged the development of local boy scout organizations . Like the Communists who later succeeded Yan, he punished habitual lawbreakers to "redemption through labour" in state-run factories. After the failed attempt by the Chinese Red Army to establish bases in southern Shanxi in early 1936 Yan became convinced that the Communists were lesser threats to his rule than either

13664-589: The valleys of the Colombian Andes between 7000 and 6000 years ago. The earliest maize plants grew a single, small ear per plant. The Olmec and Maya cultivated maize in numerous varieties throughout Mesoamerica ; they cooked, ground and processed it through nixtamalization . By 3000 years ago, maize was central to Olmec culture, including their calendar, language, and myths. The Mapuche people of south-central Chile cultivated maize along with quinoa and potatoes in pre-Hispanic times. Before

13786-458: The western border of Shanxi with Shaanxi . The Fen and Qin rivers, tributaries of the Yellow River, run north-to-south through the province, and drain much of its area. The north of the province is drained by tributaries of the Hai River , such as Sanggan and Hutuo rivers. The largest natural lake in Shanxi is Xiechi Lake , a salt lake near Yuncheng in southwestern Shanxi. Shanxi has

13908-529: Was 1110.0 billion yuan (US$ 176.2 billion), ranked 21st in China. Its per-capita GDP was 21,544 yuan (US$ 3,154). Maize Maize / m eɪ z / ( Zea mays ), also known as corn in North American English , is a tall stout grass that produces cereal grain . It was domesticated by indigenous peoples in southern Mexico about 9,000 years ago from wild teosinte . Native Americans planted it alongside beans and squashes in

14030-458: Was harvested by hand. This involved a large number of workers and associated social events (husking or shucking bees ). From the 1890s onward, some machinery became available to partially mechanize the processes, such as one- and two-row mechanical pickers (picking the ear, leaving the stover ) and corn binders, which are reaper-binders designed specifically for maize. The latter produce sheaves that can be shocked . By hand or mechanical picker,

14152-437: Was initially home to the jiedushi (commander) of Hedong, Li Cunxu , who overthrew the first of the Five Dynasties, Later Liang (907–923) to establish the second, Later Tang (923–936). Another jiedushi of Hedong, Shi Jingtang , overthrew Later Tang to establish the third of the Five Dynasties, Later Jin , and yet another jiedushi of Hedong, Liu Zhiyuan , established the fourth of the Five Dynasties ( Later Han ) after

14274-425: Was introduced into Western farming systems, it was welcomed for its productivity. However, a widespread problem of malnutrition soon arose wherever it had become a staple food . Indigenous Americans had learned to soak maize in alkali -water — made with ashes and lime — since at least 1200–1500 BC, creating the process of nixtamalization. They did this to liberate the corn hulls, but coincidentally it also liberated

14396-709: Was mostly dominated by the warlord Yan Xishan until the Chinese Communist Party took full control in 1949; Communists had already set up secret bases in 1936, but did not completely overturn Yan and the Nationalist government until 1949. Early in Yan's rule he decided that, unless he was able to modernize and revive the economy of his small, poor, remote province, he would be unable to protect Shanxi from rival warlords. Yan devoted himself to modernizing Shanxi and developing its resources during his reign over

14518-466: Was one of the 26 genetically engineered food crops grown commercially in 2016. The vast majority of this is Bt maize . Genetically modified maize has been grown since 1997 in the United States and Canada; by 2016, 92% of the US maize crop was genetically modified. As of 2011, herbicide-tolerant maize and insect-resistant maize varieties were each grown in over 20 countries. In September 2000, up to $ 50 million worth of food products were recalled due to

14640-487: Was one of the few examples in the Chinese Civil War in which Nationalist forces echoed the defeated Ming loyalists who had, in the 17th century, brought entire cities to ruins resisting the invading Manchus. Many Nationalist officers were reported to have committed suicide when the city fell. The dead included Yan's nephew-in-law, who was serving as governor, and his cousin, who ran his household. Liang Huazhi ,

14762-647: Was removed from his post in September 2014, with Wang Rulin 'helicoptered' into the provincial Party Secretary office. The GDP per capita of Shanxi is below the national average. Compared to the provinces in east China, Shanxi is less developed for many reasons. Its geographic location limits its participation in international trade, which involves mostly eastern coastal provinces. Important crops in Shanxi include wheat , maize , millet , legumes , and potatoes . The local climate and dwindling water resources limit agriculture in Shanxi. Mining-related industries are

14884-571: Was sent by the central government in 2005 to become Governor but resigned in the wake of the Shanxi slave labour scandal in 2007. He was succeeded by Meng Xuenong , who had been previously sacked as Mayor of Beijing in the aftermath of the SARS outbreak. Meng himself was removed from office in 2008 after only a few months on the job due to the political fallout from the 2008 Shanxi mudslide . In 2008, provincial Political Consultative Conference Chair, one of
