How to calculate the cost of cotton production?
The main costs of cotton production are seeds, fertilizer and labor. * * cottonseeds are mainly hairy seeds. 5 Mu of land is needed for 6 kilograms, which is about 5 yuan per kilogram, so the seed cost is about 30 yuan per mu. The Yangtze River valley is dominated by hybrids, which need 7 seeds per mu of land, with a market price of 50 won 60 yuan per jin and a cost of 35 Mel 40 yuan. The Yellow River basin is also basically about 40 yuan. Pesticides and fertilizers are basically about 60 yuan. The labor cost is basically 400 RMB500 / mu. The cost of land is about 400 yuan per mu (*). So the total cost this year is 900 won 1000 yuan.

Water floating Seedling technique of Cotton
"Cotton floating Seedling Technology" is a new cotton planting technology developed by agricultural experts in Hunan Province. this technology uses porous polyethylene foam seedling tray as carrier and mixed substrate as support. The seedling tray containing cotton seeds is put into the nutrient liquid water nursery bed for cultivation, which has significant seed saving, labor saving, yield increasing and synergism, and the seed consumption is more than 40% less than that of conventional nutrition bowl seedling transplanting cotton. The labor consumption of raising seedlings and transplanting per mu is reduced by about 10. Cotton seedlings have well-developed roots, low Lignification, soft and elastic, not easy to break, and life.

Cotton boll red rot of cotton
Symptoms of cotton boll infected with the initial amorphous disease spot, in wet weather or continuous rain, the disease spread rapidly, throughout the whole boll, some spread to the cotton fiber, producing a uniform pink or light red mildew layer, easy to stick together after rain, become a pink lump, resulting in the disease boll can not crack, cotton fiber rot into a rigid petal, seed infection, the germination rate decreased. The pathogen is the same as cotton seedling red rot. The route of transmission and the conditions of the disease are weak parasitic bacteria, which can not directly infect cotton bolls, but mainly cause the disease from the wound.
