High-yield slow-release compound fertilizer for rice cultivation and preparation method thereof

Abstract

The invention discloses high-yield slow-release compound fertilizer for rice cultivation. The high-yield slow-release compound fertilizer comprises urea, corn straws, cassava residues, attapulgite, traditional Chinese medicine dregs, sucrose, furfural residues, yeast powder, cellulase, a straw fermentation inoculant, urea phosphate, ammonium phosphate, potassium chloride, diammonium phosphate, boric acid, potassium dihydrogen phosphate, ammonium nitrate, calcium humate, magnesium humate, potassium magnesium sulphate, zinc humate, sodium humate, iron humate urate, nitrohumic acid and a slow release agent. The invention also provides a preparation method of the high-yield slow-release compound fertilizer for rice cultivation. The slow-release compound fertilizer can effectively improve the yield and quality of the crops, has excellent slow-release effects, improves the efficiency of planting and reduces the cost of planting.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a high-yield slow-release compound fertilizer for rice planting and a preparation method thereof. Background technique [0002] Agriculture is the foundation of human existence. Soil and fertilizer are the two basic elements of agricultural production. Soil is the foundation of agriculture, and fertilizer is a kind of substance that improves soil properties and soil fertility. It is the material basis of agricultural production. Advanced agricultural technology will be difficult to function without the carrier of soil fertilizer. [0003] However, excessive nitrogen release at the initial stage of fertilizer application will result in volatilization and leaching, which will not only cause losses, but also be detrimental to the growth of crop seedlings. Many nitrogen fertilizers have such problems, but most research data only focus on the problem of excessive nitrogen release ...

AI Technical Summary

Problems solved by technology

[0003] However, excessive nitrogen release at the initial stage of fertilizer application will result in volatilization and leaching, which will not only cause losses, but also be detrimental to the growth of crop seedlings. Many nitrogen fertilizers have such problems, but most research data only focus on the problem of excessive nitrogen release from fertilizers. regulation and inhibition, but ignores that most organic-inorganic compound fertilizers also have such problems

Especially when the compound fertilizer made of fermented organic matter and inorganic nitrogen fertilizer is damp or applied to the soil, urine enzyme will quickly become active and release ammonia nitrogen. At the same time, the action of digestive bacteria will also convert nitrogen to nitrate nitrogen, which will pollute the environment. larger
