AI Technical Summary

Technical Problem

Existing edible mushroom spawn preparation technologies suffer from problems such as limited raw materials, insufficient pretreatment, and unreasonable formulations, leading to nutritional imbalances, slow mycelial growth, high contamination rates, and unstable fruiting rates and quality. Furthermore, traditional sawdust raw materials are costly and scarce.

Method used

Using various agricultural and forestry wastes such as fruit tree pruning branches, grapevines, and corn cobs as raw materials, the substrate is processed through crushing, alkali soaking, washing, and draining. Combined with auxiliary materials such as wheat bran, corn flour, gypsum powder, lime, and brown sugar, the substrate formula is optimized and high-pressure steam sterilization is used to prepare nutritionally balanced and well-ventilated mushroom bags.

Benefits of technology

It achieves efficient resource utilization, reduces production costs, increases mycelial growth rate and mushroom bag quality, has a low pollution rate, high fruiting rate, and excellent mushroom quality, which is in line with the development trend of ecological circular agriculture.

Abstract

The invention discloses a preparation method of an edible mushroom bag based on agricultural and forestry wastes, and belongs to the technical field of edible mushroom cultivation. Forestry and agricultural residues such as pruned fruit tree branches, grape vines, corncobs and straw are used as main raw materials, and the fungus bag is prepared through the steps of pretreatment, ingredient mixing, bagging, sterilization, cooling, inoculation, spawn running culture and the like. By reasonably matching various agricultural and forestry wastes and optimizing the raw material ratio and process parameters, the resource utilization of the agricultural and forestry wastes is realized, the production cost of the fungus bag is reduced, the nutrition utilization rate of the culture material can be improved, the rapid growth of edible fungus hyphae is promoted, and the fruiting rate of the fungus bag and the quality of edible fungi are improved. Meanwhile, mushroom residues after the mushroom bags are used can be further processed into organic fertilizers, an ecological circulation chain of agricultural and forestry waste-edible mushrooms-organic fertilizers is formed, and the method has remarkable economic, ecological and social benefits and is suitable for large-scale industrialized production and popularization.
