Speaking of cotton planting, many people think that Xinjiang is a region where cotton is planted. In fact, there are many places to grow cotton in China, and there are many varieties of cotton. Due to its vast territory, vast geographical area and different climate and environment, cotton varieties suitable for planting in different regions are not the same. Let's follow Bian Xiao to learn about cotton varieties. Where are they suitable for planting? Speaking of cotton planting, many people think that Xinjiang is a region where cotton is planted.

Several main areas of cotton planting in China

(1) The five major cotton areas are Xinjiang cotton area, North China cotton area, Jianghuai cotton area, middle and lower reaches of the Yangtze River cotton area and Lu Yu cotton area.

(2) The three major cotton areas are: Xinjiang cotton area, cotton area in the lower reaches of the Yellow River and cotton area in the middle and lower reaches of the Yangtze River.

(3) From the main characteristics of these cotton areas, one is that the dimensions are similar, and the other is that they are all in the plain area, so Xinjiang is in the plain area near Gobi.

These are the main cotton varieties and cotton growing areas. Cotton has many functions. When choosing to plant cotton, we should choose cotton varieties according to the local climatic conditions to ensure the yield.
