Special fertilizer for single cropping rice

Abstract

The invention discloses a special fertilizer for single cropping rice. The special fertilizer is prepared by traditional Chinese medicine residue, nanometer iron-ore slag powder, wood charcoal, sepiolite, bacterial bacteria, urea, calcium superphosphate, potassium chloride, goose feather, carboxymethylcellulose, 30% of sulfuric acid, lime, zinc sulfate, ferrous sulfate, sodium molybdate, paulownia saw powder, rhizoma nardostachyos extract, willow branch powder and wintergreen oil according to a certain weight ratio. According to the special fertilizer, amino acid is generated by feathers after acid hydrolysis, trace elements or secondary elements are cheated, and a chelate structure of the trace elements or the secondary elements is reinforced by the carboxymethylcellulose, so that the trace elements or the secondary elements can be effectively utilized and ineffective releases of the trace elements or the secondary elements can be reduced; an inorganic slow release component and a soil improvement component, namely the bentonite and the wood charcoal, are added in a formula of the special fertilizer to improve the soil and to be beneficial to the effective release of fertilizer efficiency and full absorption of the fertilizer by the crops; biological insecticide components, namely the paulownia saw powder, the rhizoma nardostachyos extract and the willow branch powder, can effectively reduce pest and disease damage on the soil, are safe and pollution-free, and do not pollute an environment or the crops; and the special fertilizer has the advantages that the formula is reasonable, the nutrition is more comprehensive and balanced, the use effect is good, the utilization rate of fertilizer efficiency can be remarkably increased, the yield of the single cropping rice is greatly increased, the quality of the single cropping rice is greatly improved, and the economic benefit of the single cropping rice is increased.

Description

technical field [0001] The invention relates to a special fertilizer for single-season rice, belonging 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] Currently, there are many types of fertilizers used for single-season rice cultivation. Most of the special fertilizers for single-season rice are NPK compound fertilizers available on the market, which are mainly composed of three inorganic elements, N, P, and K. rice growth needs. However, long-term use will damage the soil aggregate structure, which will easily cause soil compaction and soil hardening, thereby affecting the growth...

AI Technical Summary

Problems solved by technology

However, long-term use will damage the soil aggregate structure, which will easily cause soil compaction and soil hardening, thus affecting the growth of single-crop rice, and the promotion effect on the growth of single-crop rice is not obvious.

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

[0004] At present, single-cropping 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 seriously affect people's physical and mental health and the competitiveness of my country's single-season rice in the international market
