Which provinces are the main producing areas of sorghum in China?

Heilongjiang, Jilin, Inner Mongolia, Liaoning, Hebei, Shanxi, Shaanxi, Anhui, Hubei, Sichuan, Guizhou, etc.

1. Spring sowing and early maturing area.

Heilongjiang, Jilin, Inner Mongolia and other provinces and regions, Hebei Province Chengde area, Zhangjiakou Baxia area, Shanxi, northern Shaanxi Province, Ningxia arid area, Gansu Province central and Hexi region.

Northern Xinjiang plains and basins, etc.

Due to the low accumulated temperature, sorghum production is susceptible to the influence of low temperature and chilling, so technical measures should be taken to prevent low temperature and promote early maturity. In this area, it is a one-year cropping system, which is usually sown in early and mid-May and harvested in September.

2. Spring sowing and late maturing area.

Most of Liaoning, Hebei, Shanxi, Shaanxi and other provinces, Beijing, Tianjin, Ningxia's Huangguan District, Gansu Province's eastern and southern Gansu, Xinjiang's southern Xinjiang.

and the Dongjiang Basin, which are the main sorghum producing areas in China, with a high yield level.

Basically, it is a one-year cropping system, and due to the good thermal conditions, the cultivated varieties are mostly late-maturing. In recent years, due to the reform of the farming system, summer-sown sorghum has been planted after wheat harvest, changing one crop a year to three crops in two years or two crops a year.

3. Spring and summer sowing area.

Parts of Shandong, Jiangsu, Henan, Anhui, Hubei, Hebei and other provinces.

Spring-sown sorghum and summer-sown sorghum account for about half, and spring-sown sorghum is mostly distributed in low-lying and saline-alkali land with relatively barren soil, and most of them are medium and late maturing varieties. Summer-sown sorghum is mainly distributed on flat fertile land, as the stubble of summer harvest crops, and early-maturing varieties with a growth period of no more than 100 days are mostly used. The cultivation system is mainly based on two crops in one year or three crops in two years.

4. Southern District.

Central. South, South China, Southwest China.

All. The southern sorghum area is widely distributed, and most of them are planted sporadically, and the provinces with relatively more planting include Sichuan, Guizhou, Hunan and other provinces. The varieties used in this area are very short-term, scattered and waxy varieties are the majority, and most of them have tillering.

The cultivation system is three crops a year, and in recent years, regenerated sorghum has developed to a certain extent.

Sorghum is not a crop native to China.

Sorghum (formerly known as Shu millet) is one of the main crops grown by Chinese farmers, and this species with a strong local flavor has a long history in China. However, sorghum is not a crop native to China, and recent research shows that cultivated sorghum is native to Africa and was domesticated from local wild species about 12,000 years ago. Later, according to the archaeological findings available, sorghum may have been introduced to India around 2000 BC.

History. According to the existing archaeological discoveries, sorghum was introduced to China during the Han and Wei dynasties, and traces of sorghum excavation have been found in 11 archaeological sites of this period, which are located in Liaoning, Inner Mongolia, Shanxi, Guangdong, Jiangsu, Shaanxi and Henan provinces. However, it is very likely that they did not come to China from the same direction.

One of these directions is the overland Silk Road in Central Asia. During the Western Han Dynasty, the Sogdians of Central Asia had already mastered the cultivation of sorghum from India, and they were subordinate to Kangju rule at that time. After Emperor Wu of the Han Dynasty opened the west of the river and the Western Regions, and the land Silk Road was opened, the Sogdians, who were skilled in commerce and trade, and other Kangju merchant groups came to the Central Plains very frequently.

It was precisely because of the close ties that had been maintained between the Central Plains and Sogdia for a long time that favorable conditions were provided for the introduction of sorghum.

The other direction is the Southwest Silk Road of Poison (India). China's Yunnan borders not only Myanmar and Laos on the Indochina Peninsula, but also only about 150 kilometers from the border of the Gongshan Mountains at the top of the Nu River Gorge in western Yunnan to the present-day state of Assam in northeastern India, which is not far from the heart of ancient India.

According to relevant research, by the end of the fourth century B.C. at the latest, with the geographical advantage of connecting mountains and rivers, China and Southeast Asia, South Asia and West Asia have opened up an international exchange artery, which is the famous "Shu Body Poison Road". Through close personnel and material exchanges, sorghum is likely to be brought into the southwest region intentionally or unintentionally in the process of exchange, and then into Shu and even the Central Plains.

Which provinces are the main producing areas of sorghum in China?

Hello, I am glad to answer for you, the main provinces of sorghum in China are: Heilongjiang, Jilin, Inner Mongolia, Guizhou, Shanxi, Hebei, Shaanxi, Hubei, Sichuan, Anhui, Liaoning and other places, I hope my help to you.

1. Where is the sorghum production area The sorghum production area is in the Qinling Mountains, north of the Yellow River, and north of the Great Wall, and it is widely distributed in China and is planted all over the country.

2. What are the sorghum cultivation areas 1. Spring sowing and early maturing areas (1) Main production areas: Heilongjiang, Jilin, all of Inner Mongolia, Chengde of Hebei Province, Zhangjiakou Baxia, Shanxi and northern Shaanxi Province, arid areas of Ningxia, central and Hexi of Gansu Province, and plains and basins of northern Xinjiang.

2) Cultivars: There are mainly 2 varieties that are early and medium-early.

3) Because sorghum is easy to cause poor growth after being exposed to low temperature and cold injury, it is necessary to prepare methods to prevent low temperature and promote early maturity in time.

4) In the spring-sown early maturing area, there is a large number of planting in the area of 3430-4850 north latitude, 300-1000 m above sea level, average annual temperature, 2000-3000 active accumulated temperature, 100-700 mm annual precipitation, and 120-150 days of frost-free period.

5) Sowing is carried out in early to mid-May and harvested in September, mainly once a year.

2. Spring sowing and late maturing areas (1) Main production areas: Liaoning, Hebei, Shanxi, Shaanxi, Beijing, Tianjin, Ningxia Huangguan District, eastern and southern regions of Gansu Province, southern Xinjiang and eastern Xinjiang basins.

2) Cultivars: mainly late-maturing varieties, one crop a year.

3) Due to the reform of the farming system, sorghum can be sown in the summer, so one crop a year has become two years three crops or two crops a year.

4) In the spring sowing and late maturing area, there is a large number of planting in the latitude of 32-4147 north, the altitude of 3-2000 meters, the average annual temperature, the active accumulated temperature of 3000-4000, the frost-free period of 150-250 days, and the annual precipitation of millimeters.

3. Spring and summer sowing area (1) Main production areas: Shandong, Jiangsu, Henan, Anhui, Hubei, Hebei.

2) Spring-sown sorghum is suitable for growing in barren low-lying and saline-alkali soil, and the method of medium and late maturity.

3) Summer-sown sorghum is suitable for growing in fertile soil, and the growth period cannot be higher than 100 days, and the cultivation is generally two crops a year or three crops in two years.

4) In the spring and summer combined sowing area, there are a large number of plantings in the areas of 2415-3815 north latitude, 24-3000 meters above sea level, 14-17 annual average temperature, 4000-5000 active accumulated temperature, 200-280 days frost-free period, and annual precipitation of 600-1300 mm.

4. Southern sorghum area (1) Main production areas: southern central China, South China and southwest China, cultivated varieties: scattered spike type, waxy varieties, cultivation system: three crops a year.

2) Most of the sorghum areas in the south are sporadically planted, and the places where the planting is more are in Sichuan, Guizhou, Hunan and other provinces.

3) The annual average temperature at latitude 1810-3010, the altitude of Tonglian at 400-1500 meters, 16-22 meters, the active accumulated temperature of 5000-6000, the frost-free period of 240-365 days, and the annual precipitation of 1000-2000 mm.
