Special cotton base fertilizer and preparation method of special cotton base fertilizer

Abstract

The invention provides a special fertilizer for cotton base fertilizer, which is made of the following raw materials in parts by weight: cottonseed cake 10-20, coated ammonium bicarbonate 15-17, superphosphate 4-6, coated potassium chloride 16- 18. Fly ash 20-30, manganese chloride 1-2, zinc sulfate 0.1-0.5, borax 0.1-0.3, medical stone 10-12, weathered coal 5-7, Buddleia powder 3-4, basil Powder 3-4, bagasse 10-15, volcanic rock 10-15, distiller's grains 18-22, carboxymethyl cellulose 3-4, 30% sulfuric acid 15-20, lime amount, animal hair 10-15, wintergreen oil 4- 6. The hair is acid-decomposed into amino acids, and then amino acid chelated micro and medium fertilizer liquids are produced, and then the volcanic rock is sintered to obtain the fertilizer carrier, the organic fertilizer is fermented, and then the nitrogen, phosphorus and potassium fertilizer is mixed with the carrier, organic fertilizer and plant insecticide, and then sprayed Amino acid chelated micro and medium fertilizer solution, granulated, and finally coated with wintergreen oil. The fertilizer of the invention can obviously improve the utilization rate of fertilizer efficiency, play a slow-release effect, reduce the amount of fertilization, and reduce pesticide residues. Improve the yield and quality of cotton.

Description

technical field [0001] The invention relates to the field of agricultural fertilizers, in particular to a special fertilizer for cotton base fertilizer and a preparation method thereof. Background technique [0002] my country is a large agricultural country. Chemical fertilizers and pesticides play a very important role in agricultural production. With the improvement of people's living standards and health awareness, people attach great importance to the safety of agricultural products, and the demand for pollution-free and green food is increasing year by year. . [0003] Currently, there are many types of fertilizers used in cotton planting. Most of the special fertilizers for cotton are NPK compound fertilizers available on the market, which are mainly composed of three inorganic elements, N, P, and K, which can meet the growth needs of cotton in a short time. However, long-term use will destroy the soil aggregate structure, easily cause soil compaction and soil harde...

AI Technical Summary

Problems solved by technology

However, long-term use will destroy the soil aggregate structure, easily cause soil compaction and soil hardening, thus affecting the growth of cotton, and the promotion effect on cotton growth is not obvious

At the same time, although pure organic fertilizer is rich in organic matter, it releases nutrients slowly, cotton absorbs slowly, and fertilizer efficiency is low, and the effective balance between various effective nutrients cannot be achieved.

[0004] At present, the control of cotton pests and diseases is mainly made of chemically synthesized pesticides and toxic chemical raw materials, applied to the soil or on agricultural cotton, and used for a long time year after year. A large number of pesticides and chemical fertilizers have caused the pests to develop drug resistance. Pollution of water sources, soil and agricultural cotton, decline in the quality of agricultural products, and excessive pesticide residues seriously affect people's physical and mental health and the competitiveness of my country's cotton in the international market
