Method for preparing biological soil conditioner by utilizing edible mushroom dregs

Abstract

The invention discloses a method for preparing a biological soil conditioner by utilizing edible mushroom dregs and belongs to the field of waste utilization. The method aims at solving the problem that at present, a large mount of edible mushroom dregs in out country is abandoned and burned, mold spores in the air and injurious insects are increased, air pollution is caused, harm is produced to human health, meanwhile a traditional soil conditioner is mainly synthesized by various chemical substances, residues in soil cause secondary pollution and the production cost is expensive. According to the method, edible mushrooms are firstly soaked with salt water, pretreatment is performed to remove hazardous substances, then the edible mushrooms are mixed with nutrients, strains are screened under sequence pressure to obtain beneficial strains and nutrient substances, then a soil extracting solution is obtained from the treated soil, and finally the beneficial strains are directionally cultured by using the extracting solution so as to obtain the biological soil conditioner.

Description

technical field [0001] The invention discloses a method for preparing a soil bio-improving agent by using edible fungus residue, and belongs to the field of waste utilization. Background technique [0002] Edible fungi have become an indispensable part of people's daily diet because they contain high protein, low fat, low energy, rich in mineral elements and vitamins. After entering the 1980s, my country's edible fungi developed extremely rapidly and became a superpower of edible fungi. With the development of edible fungi, there are more and more edible fungus residues, that is, the waste after cultivation of edible fungi. There are millions of tons of mushroom residues produced in my country every year, because most cultivators are not very aware of the nutritional value of mushroom residues. We understand that the residues of edible fungi are often discarded or burned anywhere. The residues still contain a large amount of mycelium and rich nutrients. Mold and pests are ea...

Problems solved by technology

[0004] The technical problem mainly solved by the present invention: A large amount of edible fungus slags are discarded and burned in my country at present, causing the number of mold spores and pests in the air, causing air pollution and endangering human health, while traditional soil improvers are mainly composed of various chemical substances Synthesis, residues in the soil will cause secondary pollution, and the production cost is expensive. The present invention firstly soaks the edible fungi in salt water, pre-treats them, removes harmful substances therein, and then mixes them with nutrients, and then Under the pressure of the sequence, the strains are screened to obtain beneficial strains and nutrients, and then the soil extract is obtained from the treated soil, and finally the extract is used to cultivate the beneficial strains and perform directional cultivation to obtain a soil bio-improvement agent
