What is the typical per-mu yield of cotton in jin?
Cotton is grown on a large scale in our country, and the Jianghuai Plain, Jianghan Plain, the southern Xinjiang cotton region, the North China Plain and other places are the main cotton-producing areas of our country. Cotton has a very wide range of uses, so how many jin is the per-mu yield of cotton?
1. How many jin is the per-mu yield of cotton?
The per-mu yield of cotton is related to factors such as the planting region, planting level, cotton variety and natural climate. Generally, the cotton yield of low-yield fields is about 180 to 230 kg, that of medium-yield fields is about 230 to 300 kg, and that of high-yield fields can reach 350 to 400 kg or more.
2. Classification of cotton
1. White cotton: cotton that matures normally and opens its bolls normally, regardless of whether the raw cotton is pure white, milky white or light yellow in color, is called white cotton. The vast majority of raw cotton used by cotton textile mills is white cotton.
2. Yellow cotton: in the late growth stage of cotton, the cotton bolls wither and die after being damaged by frost, and the pigment on the boll husk dyes the fibers, making the raw cotton yellow. Yellow cotton generally belongs to low-grade cotton, and cotton textile mills use only a small amount of it.
3. Gray cotton: for cotton fibers grown in rainy areas, if during the growth and development process or after boll opening there is heavy rainfall, little sunshine and low temperature, fiber maturity will be affected, and the raw cotton appears grayish white; this kind of raw cotton is called gray cotton. Gray cotton has low strength and poor quality, and cotton textile mills rarely use it.
4. Colored cotton: colored cotton refers to cotton that naturally has color, and it is developed on the basis of the original colored cotton through biological techniques such as distant hybridization and genetic modification. Natural colored cotton still retains the advantages of cotton fiber such as softness, comfort and breathability, and the cotton fabrics made from it can reduce a few printing and dyeing steps and processing costs and can appropriately avoid environmental pollution to some extent, but it lacks color hues and has insufficient color fastness, and observation for stable inheritance is still underway.
3. Main uses of cotton
Cotton can be made into fabrics of various specifications. Cotton fabrics are strong and wear-resistant, can be washed and ironed at high temperatures. Cotton cloth absorbs and releases moisture quickly, making it comfortable to wear. Both the main and by-products of cotton have high utilization value, just as predecessors said, “cotton is a treasure all over”. It is not only the most important fiber crop, but also an important oil crop, as well as a food crop with high protein content, and it is also a raw material for textiles and fine chemicals and an important strategic material. Therefore, efforts must be made to increase cotton production, do a good job in comprehensive utilization, increase production and value, so as to increase cotton farmers' income and meet the many needs of national economic development.
Cotton is one of the world's main crops, and its yield is relatively high while its production cost is relatively low, making it suitable for large-scale planting. If you do not know what crop to plant, you can consider planting cotton.
