Special base fertilizer for spring wheat and preparation method thereof

Abstract

The invention provides a special base fertilizer for spring wheat. The special base fertilizer is prepared from the following raw materials expressed in weight parts: 10 to 20 of cottonseed cakes, 4 to 5 of coated urea, 18 to 20 of calcium superphosphate, 5 to 8 of coated potassium chloride, 20 to 30 of fly ash, 1 to 2 of ferrous sulfate, 0.1 to 0.5 of zinc sulfate, 0.1 to 0.3 of borax, 10 to 12 of Chinese medical stone, 5 to 7 of charcoal, 3 to 4 of celastrus orbiculatus powder, 3 to 4 of rosebay powder, 10 to 15 of bagasse, 10 to 15 of dolomite, 18 to 22 of cow dung, 3 to 4 of carboxymethyl cellulose, 15 to 20 of 30% sulfuric acid, 5 to 10 of lime, 10 to 15 of bone meal and 4 to 6 of cottonseed oil. A preparation method for the fertilizer comprises the following steps: carrying out acidolysis on hairs to produce amino acid; producing amino acid chelated micro and medium fertilizer liquid; sintering dolomite to prepare a fertilizer carrier; fermenting an organic fertilizer; mixing a nitrogen-phosphorus-potassium fertilizer with the carrier, the organic fertilizer and a botanical pesticide; spraying the amino acid chelated micro and medium fertilizer liquid; carrying out granulation; and finally carrying out coating with the cottonseed oil. The fertilizer provided by the invention can obviously improve the utilization rate of fertilizer efficiency, exerts a slow release effect, reduces a fertilizer application amount and pesticide residue and improves the output and quality of the spring wheat.

Description

technical field [0001] The invention relates to the field of agricultural fertilizers, in particular to a special fertilizer for spring wheat 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 for spring wheat planting, among which the special fertilizer for spring wheat 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 wheat in a short time. However, long-term use will damage the soil aggregate structure, easily cause...

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 wheat, and the promotion effect on wheat growth is not obvious

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

[0004] At present, the prevention and control of spring wheat pests and diseases is mainly made of chemically synthesized pesticides and toxic chemical raw materials, applied to the soil or on agricultural wheat, and used for a long time year after year. A large number of pesticides and chemical fertilizers have caused the pests to develop resistance. Pollution of water sources, soil and agricultural wheat, 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 wheat in the international market
