Method for preparing bio-organic bacterial fertilizer by composting and aerobic fermentation of edible fungus residues

Abstract

The invention discloses a method for preparing bio-organic bacterial fertilizer by composting and aerobic fermentation of edible fungus residues. The method is characterized in that a slant surface ofstains is washed with sterile water to obtain a bacterial suspension, the bacterial suspension is added into a seed bottle under aseptic conditions and cultured to obtain a seed liquid, the seed liquid is inoculated into a fermentation bottle for enlarge culture to obtain a fermented bacterial suspension, and the fermented bacterial suspension is mixed with dried and sterilized bran for culture and then placed in a sterile room for naturally drying to obtain a solid composite bacterial agent; the edible fungus residues are mixed and stirred uniformly with cow dung and straw, turning is conducted once every three days, the water content is adjusted, the solid composite bacterial agent is added twice, and aerobic composting is conducted; water is added into the edible fungus residues, the humidity is adjusted, the edible fungus residues are piled into a conical shape, and fermentation is conducted for one week; bacillus subtilis bacterial liquid, bacillus licheniformis bacterial liquid,bacillus mucilaginosus bacterial liquid and bacillus laterosporus bacterial liquid are mixed with water and uniformly stirred with fermented fungus residue heaps, fermentation is continued, turning treatment is conducted during fermentation, and the mixture above is subjected to composting and uniform mixing with edible fungi to obtain the bio-organic bacterial fertilizer.

Description

technical field [0001] The invention relates to the field of soil improvement fertilizers, in particular to a method for preparing bio-organic bacterial fertilizers by composting edible fungus residues through aerobic fermentation. Background technique [0002] Along with the increase of edible fungus demand, the quantity of edible fungi dregs is also constantly increasing. A large amount of edible fungus residues are discarded at will, causing environmental pollution and waste of resources. The production of organic fertilizer with edible fungus residue can be realized [0003] The resource utilization of fungus residue can avoid environmental pollution at the same time. Contents of the invention [0004] The technical problem mainly solved by the present invention is to provide a method for preparing bio-organic bacterial fertilizer by aerobic fermentation of edible fungus residue composting, and the bio-organic bacterial fertilizer prepared according to the process ca...
