Where are the main cotton differences in our country? What are the three major cotton areas in my co

China is one of the world's major cotton-producing countries. Cotton is an important cash crop, and its planting area ranks first among cash crops, accounting for about 1 3 of the sown area of cash crops. Cotton is an important raw material for the textile industry, national defense, chemical, pharmaceutical and other industries are also inseparable from cotton, cotton stalks can be used to make paper, cottonseeds can be squeezed for oil, and cottonseed cake is a high-quality feed.

Therefore, cotton production is of great significance in national construction and people's lives. China's cotton production areas are widely distributed, and the country is divided into three main cotton areas according to the natural conditions, cultivation management level and planting historical conditions. See Figure 5-3.

1) Cotton area of the Yellow River Basin.

It includes seven provinces and cities of Shandong, Hebei, Henan, Shanxi, Shaanxi, Beijing and Tianjin north of the Qinling-Huai River, south of the Great Wall, and east of Liupan Mountain. The cotton output is the largest in Shandong, Henan and Hebei provinces. This area has a long history of cotton planting, superior natural conditions, flat terrain in the area, less autumn rain, and sufficient sunshine, which is conducive to the growth of cotton, and has become the largest cotton producing area in China, and its planting area accounts for 1 2 of the national cotton field area.

2) Cotton area in the Yangtze River Basin.

This area includes Shanghai, Zhejiang, Jiangsu, Anhui, Jiangxi, Hunan, Hubei and other provinces and cities, and Hubei and Jiangsu provinces have the largest output. The region has a long history of cotton planting, high technical level, sufficient labor, developed textile industry in the region, and convenient transportation conditions, making the region the cotton area with the highest cotton yield and commodity rate in the country, and also the second largest cotton-producing area in China. However, in autumn, there is more rain, high humidity and less sunshine, which affects the cotton spit and the quality of cotton is not as good as that of the cotton area in the Yellow River Basin.

3) Northwest Inland Cotton Region.

It includes Xinjiang and the Hexi Corridor of Gansu Province. This area is located in an arid area, with less precipitation, superior light conditions, large temperature difference, less pests and diseases, good cotton quality, is the third largest cotton-producing area in China, and is also a high-quality long-staple cotton producing area in China.

In Xinjiang, Xinjiang's long-staple cotton is world-famous and the largest in China. It's hard to say the worst, and it's as bad as it gets.

Xinjiang. Long-staple cotton.

The difference is the cotton mixed with soil impurities.

The three major cotton-producing areas in China are the Yellow River Basin, the Yangtze River Basin and Xinjiang.

The country is divided into three major cotton areas: the Yangtze River Basin, the Yellow River Basin and the Xinjiang Cotton Region.

Cotton area in the Yangtze River Basin: including Shanghai, Zhejiang, Jiangsu, Hubei, Anhui, Sichuan, Jiangxi, Hunan 8 provinces and cities, the planting area has been stable and decreasing in recent years.

The cotton area of the Yellow River Basin is divided into five provinces and regions, including Henan, Hebei, Shandong, Shanxi, and Shaanxi, and the planting area of hunger caves has been relatively stable in recent years.

Xinjiang cotton area: including Xinjiang and the Hexi Corridor, the planting area has increased steadily. Xinjiang cotton is known for its long fiber, clean color and strong tensile force, and is the cotton area with the most development potential in China

Xinjiang is rich in water, soil, light and heat resources, has an arid climate and little rainfall, and has unique conditions for planting cotton, and the cotton planting area has increased rapidly in recent years.

You guess the statutory holidays, I have a holiday for you, oh, room hygiene ii, during the Mo; Is it an excuse for comfort to go crazy ah my ** thinks,; Yes.

I don't know if the question you are asking is Chinese or global.

If it is the main cotton producing area in China.

Then distributed in the middle and lower reaches of the Yellow River and the Yangtze River, Xinjiang is an important long-staple cotton producing area in China, if you ask about the world's main cotton producing areas.

The world's three largest cotton producing regions: China, the United States, India.

The world's major cotton producing areas: China, the United States, India, Uzbekistan, Egypt, etc. Among them, China has the largest unit output, and Uzbekistan is known as the "country of platinum". ）

Cotton is an extremely important cash crop in China and the main raw material for the textile industry. It is recorded that cotton was widely cultivated in Hainan Island, Yunnan, Guangxi and Xinjiang more than 2,000 years ago. At the end of the Song Dynasty and the beginning of the Yuan Dynasty, cotton planting in the Yangtze River and Yellow River basins had become more and more common, and grass cotton (North Road) and Asian cotton (South Road) were mainly planted at that time.

After the introduction of upland cotton from the United States in 1865, it was gradually improved and developed, and the cotton yield increased significantly. Since 1982, China's total cotton output has been the first in the world, accounting for about 1.4 of the world's total. At present, China has become the world's second largest cotton exporter after the United States, and the output of cottonseed oil has accounted for 1 4 percent of the total output of various vegetable oils.

China's cotton production is roughly distributed between 18°N, 46°N, 76°E and 124°E, and cotton is planted in the south to Hainan Island, north to the central and western parts of Liaoning Province and northern Xinjiang, but it is mainly distributed in the Yangtze River, Huaihe River, Yellow River Basin Plain and Xinjiang Autonomous Region, Xinjiang, Sichuan, Henan, Hubei, Jiangsu, Anhui, Hunan and Hebei are the main cotton producing areas. The climate of the inland region of the northwest has created favorable conditions for the high yield and high quality of cotton in the irrigated land of Xinjiang cotton area, and this area is becoming an important production base of high-quality, high-yield cotton and special cotton (island cotton) in China, and its total output, yield and quality rank first among all provinces (regions) in the country. In 2000, the sown area of cotton in China's economic crops accounted for about 1 3, and the sown area of cotton in the country in 2000 was 10,000 hm2, with an average yield of 1028 kg hm2 and a total output of 10,000 tons.

Only scattered areas in southern Liaoning and Jilin in Northeast China can grow extra-early maturing Liaoning cotton system type cotton varieties. It starts from Dengta County in the east, Lingyuan County in the west, Jin County in the south, and Kangping County in the north. 100m above sea level.

The frost-free period of the whole year is 150-170 days, which is the shortest growing period in the country. The average annual sunshine is 2330-3000 hours.

Liaoning has a history of more than 400 years of cotton planting, mainly distributed in the alluvial plains of the Daling River, Xiaoling River, Huanyang River, Daughter River and other river basins. The varieties that have been promoted are Chaoyang Cotton No. 1, Jinmian No. 1, Xiongyue Cotton 51, Black Mountain Cotton No. 1, Liaomian No. 3 to Liaomian No. 10.

Cotton should be there, the area may not be large.
