Special late rice fertilizer and preparation method of special late rice fertilizer

Abstract

The invention provides a special late rice fertilizer. The special late rice fertilizer consists of the following raw materials in parts by weight: 10-20 parts of bean pulps, 8-10 parts of enveloped sulfur urea, 24-26 parts of enveloped ammonium dihydrogen phosphate, 8-10 parts of potassium sulphate, 20-30 parts of plant ashes, 1-2 parts of ferrous sulfate, 1-2 parts of zinc sulfate, 0.1-0.3 part of sodium borate, 10-12 parts of gelatins, 5-7 parts of fulvic acid, 3-4 parts of poplar saw dust powders, 3-4 parts of oleander powders, 10-15 parts of bagasse, 10-15 parts of calcium carbonate, 18-22 parts of Chinese medicine residues, 3-4 parts of carboxymethylcellulose, 15-20 parts of 30% of sulfuric acid, 5-10 parts of limes, 10-15 parts of chicken feathers and 4-6 parts of cottonseed oil. A preparation method of the special late rice fertilizer comprises 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 quartz sands to prepare a fertilizer carrier, fermenting an organic fertilizer, mixing a 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, then granulating, and finally adopting the wintergreen oil for enveloping. According to the special rapeseed 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 the late rice are improved.

Description

technical field [0001] The invention relates to the field of agricultural fertilizers, in particular to late rice special fertilizers 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 early rice fertilizers are mostly 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 rice in a short time. However, long-term use will destroy the soil aggregate structure, easily cause soil compaction and soil hardening, thus affect...

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
