Highly-slow-release organic compound fertilizer capable of optimizing soil structure for rice cultivation

Abstract

The invention discloses highly-slow-release organic compound fertilizer capable of optimizing a soil structure for rice cultivation. Raw materials for the organic compound fertilizer comprise corn stalks, rapeseed cake meal, spent mushroom compost, stone powder, rice hull powder, fly ash, urea phosphate, compound ammonium nitrate, zinc humate, carbonyl diamide, monoammonium phosphate, potassium dihydrogen phosphate, potassium sulfate, ammonium sulfate, ferrous sulfate, boric acid, potassium nitrate, calcium nitrate, calcium dihydrogen phosphate, citric acid residues, diatomaceous earth, vermiculite, a soil conditioner and a modification slow-release formulation. The organic compound fertilizer is used for rice planting, and has high slow-release performance, the requirement of rice planting on nutrients can be met, the soil structure can be optimized, soil depletion and hardening can be avoided, and when the organic compound fertilizer is applied to the rice planting, the yield and quality of rice are improved.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to an organic compound fertilizer with high slow release and optimized soil structure for rice planting. Background technique [0002] my country is a big rice planting country. Most of the fertilizers used for rice planting are simple fertilizers. Due to the low cost of simple fertilizers, the current fertilizers for rice production in my country are still based on simple fertilizers such as ammonium bicarbonate, urea, superphosphate or calcium magnesium phosphate fertilizer, and potassium chloride. Lord, for farmers, although my country vigorously promotes soil testing and formula fertilization technology, it is still difficult to scientifically and rationally fertilize. At present, the development trend of compound fertilizers is rapid, but the use of compound fertilizer formulas is chaotic, and unreasonable formulas applied to crops are more likely to lead to crop yield reduc...
