Organic fertilizer specially used for acidified soil and preparation method of same

Abstract

The invention discloses an organic fertilizer specially used for acidified soil, which comprises: 15-30 parts of coking coal charcoal, 10-20 parts of attapulgite, 10-15 parts of bio-charcoal, 0.5-1 part of a bio-microbial agent, 0.5-1 part of a bio-enzyme agent, 8-15 parts of drainage oil, 10-15 parts of fruit dregs, 7-12 parts of lime powder, 20-30 parts of bentonite, 3-5 parts of shell powder, 20-30 parts of banana stalk, 20-30 parts of tea residue, 20-30 parts of papermaking waste liquor, 10-20 parts of an amino acid chelating liquid, etc. In the organic fertilizer, the coking coal charcoal, fruit dregs, shell powder, banana stalk, tea residue, papermaking waste liquor, soybean sauce residue and rapeseed cake are added, and through enzymolysis and fermentation effects of the enzyme agent and bio-microbial agent, macromolecule proteins in the components are decomposed into small-molecular peptides, and majority of organic substances are fermented and decomposed so as to supply abundant nutrients to the acidified soil, thereby significantly improving soil fertility, promoting quick growth of plants, and enhancing acidification resistance of the plants.

Description

technical field [0001] The invention relates to the technical field of fertilizers. More specifically, the invention relates to a special organic fertilizer for acidifying soil and a preparation method thereof. Background technique [0002] Soil acidification refers to the process in which the soil absorptive complex accepts a certain amount of exchangeable hydrogen ions or aluminum ions, resulting in the leaching of alkaline (basic) ions in the soil. Acid rain can cause soil acidification. The soil in southern my country is mostly acidic, and the acid rain has accelerated the acidification process; the soil in northern my country is alkaline and has a strong buffer capacity for acid rain, so it cannot be acidified for a while. The soil contains a large amount of aluminum hydroxide. After the soil is acidified, it can accelerate the weathering of primary and secondary minerals containing aluminum in the soil and release a large amount of aluminum ions, forming aluminum com...

AI Technical Summary

Problems solved by technology

Acid rain can still accelerate the loss of soil mineral nutrients; change the soil structure, lead to soil barrenness, and affect the normal growth of plants; acid rain can also induce plant diseases and insect pests and reduce crop yields
