A method for comprehensive utilization of edible mushroom residue

Abstract

The invention relates to a method for comprehensive utilization of edible fungus residues. The method comprises the steps of 1, conducting steam treatment on waste bacteria sticks after impurity removal and smashing, so that pretreated fungus residues are obtained; 2, adjusting the water content and pH of the pretreated fungus residues, and building a heap for solid aerobic fermentation, so that primarily fermented fungus residues are obtained; 3, mixing the primarily fermented fungus residues with water in proportion, conducting aerated fermentation constantly, conducting filtration, and drying and smashing filter residues to obtain vegetable cultivation base fertilizer, wherein filtrate serves as an edible fungus growth promotion and yield increase agent. Mycoprotein, polysaccharide, oligosaccharide, enzymes, microorganisms and other bioactivators rich in fungus residues are fully utilized, mycoprotein, cellulose and lignin are further degraded into substances capable of being absorbed by edible fungi easily, the edible fungus growth promotion and yield increase agent which contains various physiological activators and nutrients and can promote edible fungus growth is obtained through extraction, and filter residues are used for preparing a vegetable seedling culture medium.

Description

technical field [0001] The invention relates to a method for comprehensive utilization of edible fungus residues, and belongs to the technical field of utilization of edible fungus cultivation waste. Background technique [0002] In recent years, my country's edible fungus industry has developed rapidly, especially the number of factory production enterprises has grown rapidly, and has great development potential. However, the common raw materials such as cottonseed husks, wheat straw, and corncobs used for the cultivation of edible fungi are less and less. The rise in the price of these raw materials has led to a decline in the overall benefits of the edible fungus industry and increased pressure on market competition. In the production of edible fungi, nutritional regulators are sometimes added to stimulate the growth of edible fungi and increase the yield. Many of these nutrient regulators are composed of chemical preparations and hormones. The effect of the use of mixin...

Problems solved by technology

Appropriately adding edible fungus slag to edible fungus compost has a good effect on increasing the growth rate of edible fungal mycelium, neat budding, early mushrooming, and increasing production. The type is related to the degree of degradation and utilization, so it is not easy to strictly control the amount of bacterial residue added to the culture material, and excessive addition of the culture material will cause nutritional deficiencies

Moreover, the fungus residue is easy to breed miscellaneous bacteria and pathogenic bacteria, which will cause safety hazards such as contamination of the fungus bag. Improper treatment of the fungus residue will significantly reduce the physical and chemical properties, which will seriously affect the production of edible fungi.

[0004] In addition, because the edible fungus residue is loose and has good air permeability, the total pores and water-holding pores are large, and the organic matter and available nitrogen, phosphorus, potassium and other nutrients are high, it can be used as a cultivation substrate for horticultural gardens, but the EC value of the mushroom residue Higher, it is easy to lead to the accumulation of salt in the soil; as a seedling substrate, it will cause yellowing of the leaves of the seedlings, weak growth, and browning of the roots.
