Special fertilizer for cotton base fertilizer

Abstract

The invention discloses a special fertilizer for a cotton base fertilizer. The special fertilizer is prepared by silkworm excrement, wintergreen oil residue, decomposed coal, diatomite, biological bacteria, urea, diammonium hydrogen phosphate, potassium sulfate, goose feather bar, carboxymethylcellulose, 35% of sulfuric acid, lime, zinc sulfate, magnesium sulfate, manganese sulfate, nanometer iron-ore tailing powder, sweet wormwood extract, azadirachtin 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 diatomite and the decomposed coal, 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 nanometer iron-ore tailing powder, the sweet wormwood extract and the azadirachtin can effectively reduce pest and disease damage of 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 and the quality of cotton are greatly improved, and the economic benefit of the cotton is increased.

Description

technical field [0001] The invention relates to a special fertilizer for cotton base fertilizer, which belongs to the technical field of agricultural fertilizers. Background technique [0002] my country is a big agricultural country. 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] At present, there are many types of fertilizers used in cotton planting. Among them, the special fertilizers for cotton are mostly NPK compound fertilizers that can be purchased in the market. It is mainly composed of three inorganic elements, namely N, P and K, which can meet the growth needs of cotton in a short time. However, long-term use will destroy the soil aggregate structure, easily cause soil compaction and soil hardening, ther...

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 cotton, and the promotion effect on cotton growth is not obvious

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

[0004] At present, cotton is mainly used to control diseases and insect pests by
