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

Abstract
The invention provides a special fertilizer for early rice. The special fertilizer is prepared by the following raw materials by weight: 10-20 parts of vinasse, 8-10 parts of coated urea, 35-45 parts of calcium superphosphate, 8-10 parts of coated potassium chloride, 20-30 parts of decomposed coal, 1-2 parts of ferrous sulfate, 1-3 parts of zinc sulfate, 0.1-0.3 part of borax, 10-12 parts of medical stone, 5-7 parts of fulvic acid, 3-4 parts of radix euphorbiae lantu powders, 3-4 parts of oleander powders, 10-15 parts of bagasse, 10-15 parts of dolomites, 18-22 parts of chicken manure, 3-4 parts of carboxymethylcellulose, 15-20 parts of 30% of sulfuric acid, 5-10 parts of limes, 10-15 parts of tea seed meals and 4-6 parts of cottonseed oil. A preparation method for the special fertilizer comprises the steps as follows: carrying out acidolysis on hair to obtain amino acid; generating an amino acid chelated micro or medium fertilizer solution; sintering the dolomites to prepare a fertilizer carrier; fermenting by an organic fertilizer; mixing a nitrogen-phosphorus-potassium mixed fertilizer and the carrier with the organic fertilizer and a plant insecticide; spraying the amino acid chelated micro or medium fertilizer solution; granulating; and finally coating with the cottonseed oil at last. According to the special fertilizer, the utilization rate of fertilizer efficiency can be remarkably increased, the slow release effect is achieved, the fertilizing amount is reduced, and the pesticide residues are reduced, so that the yield of the rice is increased and quality of the rice is improved.
Description
technical field [0001] The invention relates to the field of agricultural fertilizers, in particular to a special fertilizer for early 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 and soil harden...
