Where is cotton mainly distributed in China?

Cotton is an extremely important cash crop in China and the main raw material of textile industry. According to records, more than 2,000 years ago, China planted cotton extensively in Hainan Island, Yunnan, Guangxi and Xinjiang. At the end of Song Dynasty and the beginning of Yuan Dynasty, cotton planting became more and more common in the Yangtze River and Yellow River basins. At that time, grass cotton (North Road) and Asian cotton (South Road) were mainly planted. 1865 after the introduction of upland cotton from the United States, it was gradually improved and developed, and the cotton output was significantly improved. Since 1982, China's total cotton output has been ranked first in the world, accounting for about 1/4 of the world. At present, China has become the second largest cotton exporter in the world after the United States, and the output of cottonseed oil has accounted for 1/4 of the total output of various vegetable oils. China's cotton production is generally distributed between18 N ~ 46 N and 76 E ~124 E. Cotton is planted in Hainan Island in the south, central and western Liaoning Province and northern Xinjiang, but it is mainly distributed in the Yangtze River, Huaihe River, Yellow River Basin, Xinjiang Autonomous Region, Xinjiang, Sichuan, Henan, Hubei and Jiangsu. Northwest inland climate has created favorable conditions for high yield and high quality irrigated cotton in Xinjiang cotton region. This area is becoming an important production base of high-quality and high-yield cotton and special cotton (island cotton) in China, with the total output, yield and quality ranking first in all provinces (regions) in China. The sown area of cash crops in China accounts for about 1/3. In 2000, the cotton planting area in China was 3,725,600 hm2, with an average yield of 65,438 0.028 kg/hm2 and a total output of 3,828,800 t. ..
