Cotton is planted on a large scale in China. Jianghuai Plain, Jianghan Plain, South Xinjiang Cotton Area and North China Plain are the main cotton producing areas in China. Cotton is widely used, so how many catties of cotton yield per mu?

I. How many catties of cotton yield per mu?

Cotton yield per mu is related to planting area, planting level, cotton variety, natural climate and other factors. The average cotton yield in low-yield fields is about 180 to 230 kg, that in middle-yield fields is about 230 to 300 kg, and that in high-yield fields can reach 350 to 400 kg or more.

2. Classification of cotton

1. White cotton: normal maturity, normal boll cotton, regardless of the color of raw cotton was white, milky white or light yellow, said white cotton. Most of the raw cotton used in cotton mills is white cotton.

3. Grey cotton: cotton fiber grown in rainy areas, in the process of growth and development or after opening boll, such as more rainfall, less sunshine, low temperature, fiber maturity will be affected, raw cotton appears gray, this raw cotton is called gray cotton. Grey cotton has low strength and poor quality, and is rarely used in cotton mills.

4. Colored cotton: Colored cotton refers to cotton with natural color. It is cultivated on the basis of the original colored cotton by biotechnology such as distant hybridization and transgenic. Natural colored cotton still maintains the original soft, comfortable, breathable and other advantages of cotton fiber.

It is not only the most important fiber crop, but also an important oil crop, a grain crop containing high protein, or a textile, fine chemical raw material and important strategic materials. Therefore, efforts must be made to increase cotton production, do a good job in comprehensive utilization, increase production and increase value, so as to increase cotton farmers 'income and meet the needs of various aspects of national economic development.

Cotton is one of the main crops in the world, and the yield is relatively high, the production cost is relatively low, suitable for large-scale planting. If you don't know what to plant, consider planting cotton.
