High-slow release organic fertilizer for improving micro-ecological structure of soil and preparation method of high-slow release organic fertilizer

Abstract

The invention discloses a high-slow release organic fertilizer for improving the micro-ecological structure of soil. The high-slow release organic fertilizer comprises raw materials, including urea, monoammonium phosphate, potassium fulvic acid, ammonium chloride, diammonium hydrogen phosphate, ferrous sulfate, zinc sulfate, ammonium molybdate, ammonium nitro complex, ammonium sulfate, vermiculite, lime powder, kaolin, sesame dregs, stannous chloride, sodium hydrogen sulfite, borax, silkworm excrement, cow dung, bean cakes, cottonseed meal, corn straw, rapeseed cakes, bagasse, oil cakes, EDTA (Ethylene Diamine Tetraacetic Acid) chelate, humic acid, EM (Effective Microorganisms) bacteria, amino acid chelate and a modified slow-release agent. The invention further discloses a preparation method of the high-slow release organic fertilizer for improving the micro-ecological structure of soil. The prepared high-slow release organic fertilizer has an excellent slow-release property, can provide rich nutrient substances for crops, can promote crop growth, and can increase the yield and improve the quality of the crops.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a high slow-release organic fertilizer for improving soil micro-ecological structure and a preparation method thereof. Background technique [0002] At present, chemical fertilizers are widely used in a large amount and have become one of the most important means of production in agricultural production, accounting for a large share of agricultural industry costs. A large number of long-term scientific researches have shown that the utilization rate of fertilizers is low, and one of the important reasons why nitrogen, phosphorus, and potassium cannot be fully utilized by crops is that the existing traditional inorganic fertilizers dissolve too quickly, which accelerates the decomposition of fertilizers by soil microorganisms and accelerates the rate of nutrient degradation. The conversion, volatilization, leaching, and physical and chemical fixation of traditional chemical fertilizers ...

AI Technical Summary

Problems solved by technology

The adverse consequences of extensive application of traditional inorganic fertilizers are: soil compaction, leaching of nutrients, loss of runoff, eutrophication of surface water, excessive nitrate nitrogen content in groundwater and crops, and increasing nitrogen oxide content in the atmosphere
