Special winter wheat base fertilizer and preparation method of special winter wheat base fertilizer

Abstract

The invention provides a special winter wheat base fertilizer consisting of the following raw materials in parts by weight: 10-20 parts of tea-seed pancakes, 4-5 parts of sulfur coated urea, 18-20 parts of enveloped diammonium phosphate, 5-8 parts of potassium chloride, 20-30 parts of coal ashes, 1-2 parts of ferrous sulfate, 0.1-0.5 part of zinc sulfate, 0.1-0.3 part of boric acid, 10-12 parts of sepiolite, 5-7 parts of bamboo charcoals, 3-4 parts of celastrus orbiculatus powders, 3-4 parts of oleander powders, 10-15 parts of bagasse, 10-15 parts of iron ores, 18-22 parts of cow dung, 3-4 parts of carboxymethylcellulose, 15-20 parts of 30% of sulfuric acid, 5-10 parts of limes, 10-15 parts of bean pulps and 4-6 parts of epoxidized soybean oil. The special winter wheat base fertilizer is prepared by a preparation method comprising the following steps: conducting acidolysis on hairs to generate amino acid, then generating a micro element fertilizer liquid and an intermediate element fertilizer liquid chelated with amino acid, then sintering the iron ores to prepare a fertilizer carrier, fermenting an organic fertilizer, mixing nitrogen-phosphorus-potassium fertilizer, the carrier, the organic fertilizer and a vegetable insecticide, then spraying the micro element fertilizer liquid and the intermediate element fertilizer chelated with amino acid, granulating, and finally adopting the epoxidized soybean oil for enveloping. According to the special winter wheat base fertilizer provided by the invention, the fertilizer utilization ratio is improved obviously, the slow release effect is achieved, the fertilizer application amount is lowered, the pesticide residual is lowered, and the output and the quality of winter wheat are improved.

Description

technical field [0001] The invention relates to the field of agricultural fertilizers, in particular to a special base fertilizer for winter wheat 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 winter wheat planting. Most of the special fertilizers for winter wheat are commercially available NPK compound fertilizers, which are 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 soil compaction and soil h...

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 winter wheat pests and diseases is mainly made of chemically synthesized pesticides and toxic chemical raw materials, which are applied to the soil or crops, 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 crops, 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
