Fertilizer special for hybrid rice

Abstract

The invention discloses fertilizer special for hybrid rice, which is prepared by barnyard manure, humic acid, bamboo charcoal, medical stone, biological bacterium, ammonium bicarbonate, calcium superphosphate, potassium chloride, bean pulp, cellulose glycolate, 35% sulfuric acid, lime, zinc sulfate, ferrous sulfate, sodium borate, nano iron ore milltailings powder, eucalypt saw dust, nano river sand powder and vegetable oil according to a certain weight proportion, wherein amino acid is generated by acid hydrolysis feather; secondary elements are chelated with microelements; a chelation structure is added to the cellulose glycolate, which is benefit to effectively use the secondary elements and the microelements; unavailable release of the secondary elements and the microelements is reduced; according to a formula of the invention, inorganic slow release component medical stone and soil improvement component bamboo charcoal are increased, thus, soil can be improved; the fertilizer is released effectively and is absorbed by crops completely; biological pesticide component can effectively reduce soil pest and disease damage according to the eucalypt saw dust and is safe and pollution-free and has no pollution to environment and the crops; according to the invention, the fertilizer is characterized by reasonable formula, more comprehensive and balanced nutrition, good use effect and can increase fertilizer utilization rate obviously; thus, output and quality of the hybrid rice are improved greatly so as to increase economic benefit of the hybrid rice.

Description

technical field [0001] The invention relates to a special fertilizer for hybrid rice and belongs to the technical field of agricultural fertilizers. 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 hybrid rice cultivation, among which the special fertilizer for hybrid rice mostly adopts NPK compound fertilizer available on the market, which is mainly composed of three inorganic elements N, P, and K, which can meet the growth of hybrid rice in a short time need. However, long-term use will damage the soil aggregate structure, easily cause soil compaction and soil hardening, thereb...

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 hybrid rice, and the promotion effect on hybrid rice growth is not obvious

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

[0004] At present, hybrid rice is mainly used to control diseases and insect pests by mixing and stirring chemical agents and toxic pesticides, applying them to the soil or crops, and using them for a long time year after year. A large amount of pesticides and fertilizers will cause the pests to develop drug resistance, and the soil will harden. Pollution of water sources, soil and crops, decline in the quality of agricultural products, and excessive pesticide residues have seriously affected people's physical and mental health and the competitiveness of my country's hybrid rice in the international market
