Biological soil conditioning agent containing sugar mill alcohol waste liquid, filter residue or peat

Abstract

The invention relates to a biological soil conditioning agent containing sugar mill alcohol waste liquid, filter residue or peat. The biological soil conditioning agent is characterized by being prepared from sugar mill alcohol waste liquid treated by acid and alkali treatment, peat and sugar mill filter residue obtained from microorganism fermentation, wherein the ratio of the sugar mill alcohol waste liquid treated by the acid and alkali treatment, the peat and the sugar mill filter residue obtained from the microorganism fermentation is (2000-5000): (100-300): (500-800) in parts by weight. The biological soil conditioning agent disclosed by the invention can provide balanced influence on the crops and can optimize structural balance of the soil, and can maintain sufficient soil nutrition for a long period and improve crop yield. And furthermore, the biological soil conditioning agent disclosed by the invention can additionally reduce heavy metal content in the crops.

Description

technical field [0001] The invention belongs to the field of fertilizers, and in particular relates to a biological soil conditioner containing sugar factory alcohol waste liquid, filter mud or peat. Background technique [0002] In the prior art, filter mud, bagasse, sludge, and alcohol waste liquid are used to prepare bio-organic fertilizers, and microbial fermentation is used to prepare organic compound fertilizers. [0003] For example, patent CN1171384A discloses a process for producing active organic compound fertilizers using molasses alcohol waste liquid, which uses bagasse, alcohol waste liquid, filter mud and sludge for fermentation, and the microorganisms used are saprophytic microorganisms, humic acid bacteria, nitrogen-fixing bacteria, Potassium bacteria, phosphorus solubilizing bacteria and other fungi are fermented, and other trace element compounds are added to prepare organic compound fertilizer. [0004] CN1327965A discloses a method for producing microbia...

AI Technical Summary

Problems solved by technology

[0010] In the above invention, microbial strains are used in the preparation of fertilizers and the process of preparing fertilizers, but the mixture of alcohol waste liquid and other components needs to be obtained by fermentation, and the filter mud should also be mixed with other components for fermentation. This kind of fermentation method simplifies the process to a certain extent, but the effect is not ideal, especially the pertinence is not good, because all the beneficial ingredients are degraded indiscriminately, no matter what kind of crop it is for, all of them The process used is the same, that is, mixed fermentation
