Special fertilizer for single cropping rice and preparation method of special fertilizer

Abstract

The invention provides a special fertilizer for single-season rice, which is made of the following raw materials in parts by weight: 10-20 parts of cottonseed cake, 8-10 parts of coated nitrogen, phosphorus and potassium ternary compound fertilizer, 25-40 parts of superphosphate, and Potassium Chloride 8-10, Plant Ash 20-30, Ferrous Sulfate 1-2, Zinc Sulfate 1-2, Borax 0.1-0.3, Medical Stone 10-12, Peat 5-7, Snakevine Powder 3-4, Oleander powder 3-4, bagasse 10-15, dolomite 10-15, chicken manure 18-22, carboxymethyl cellulose 3-4, 30% sulfuric acid 15-20, lime 5-10, chicken feather 10- 15. Propylene glycol sebacate polyester 4-6. The hair is acid-decomposed into amino acids, and then the amino acid chelated micro and medium fertilizer liquid is produced, and then the dolomite 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 pesticides, Spray amino acid chelated micro and medium fertilizer liquid, granulate, and finally use propylene glycol sebacate polyester coating. 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 rice.

Description

technical field [0001] The invention relates to the field of agricultural fertilizers, in particular to a special fertilizer for single-season rice 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] There are many types of fertilizers currently used for rice cultivation, among which the special fertilizer for rice mostly adopts the NPK compound fertilizer available in the market, which is mainly composed of three inorganic elements N, P, and K, which can meet the growth needs of rice in a short time. However, long-term use will destroy the soil aggregate structure, easily cause soil compaction an...

AI Technical Summary

Problems solved by technology

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

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

[0004] At present, the prevention and control of rice pests and diseases is mainly made of chemically synthesized pesticides and toxic chemical raw materials, which are applied to the soil or on agricultural rice, 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 rice, 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 rice in the international market
