Description

technical field [0001] The invention belongs to the technical field of plant fertilizer processing, in particular to an organic fertilizer for improving cotton yield and a preparation method thereof. Background technique [0002] Cotton is an important economic crop and a major agricultural product, and it is the main source of income for farmers in production areas and local finance. The commodity rate of cotton is as high as 95%, which is the highest among grain, cotton and oil field crops. The output value of national cotton production accounts for up to 7-8% of the total agricultural output value, while the sown area only accounts for 3-4%, and the annual output value is more than 50 billion yuan. In addition, the cash input in cotton production can obtain a higher return, and the rate of return is generally 0.5-1 times higher than that of food crops. Among the more than 1,100 cotton-producing counties in the country, more than 150 base counties’ fiscal revenue mainly ...
