Modification treatment technique for yield increase of hard culture medium mushroom

Abstract

During mushroom planting production, except for the demand for sufficient nutritional substances on a culture medium, mushroom sticks are required to have forming strength, air permeability, easy hypha invasion and the like. A mushroom culture medium comprises 70% or above of hard materials including cottonseed hull, oak chips, sawn timber chips and the like, which are compact in texture. The contents of such nutritional substances as cellulose protein and the like in the culture medium are high, and the produced mushroom is good in quality. In order to guarantee the air permeability, large-particle mixtures are generally used, and as the hard particles with compact textures lead to difficult core invasion of hyphae, the utilization ratio of raw materials is low. Explosion puffing equipment is utilized to perform puffing treatment on the hard culture medium to enable tissues to become loose and porous, so that large particles of the raw materials are maintained to guarantee the air permeability, the hyphae can easily invade the cores of the particles, and accordingly, the utilization ratio of the raw materials is improved. As cellulose substances are degraded, time for edible mushrooms to degrade the cellulose substances through self-metabolism is shortened, and carbon sources required for growth of the edible mushrooms are increased. Protein in the culture medium is subjected to denaturation, and part of protein is degraded into free amino acids, so that the edible mushroom culture medium is richer in nutrition, absorption and growth of the edible mushrooms are facilitated, particularly, in the early growth stage of the hyphae, owing to rich nutrition, the hyphae grow to be thick, accordingly, the mushroom quality is improved, the mushroom yield is increased, the production time is shortened, and economic benefits are improved.

Description

technical field [0001] The invention relates to the field of edible fungus production, in particular to a production-increasing and modifying treatment method for hard compost of shiitake mushrooms. Background technique [0002] In the cultivation and production of shiitake mushrooms, in addition to sufficient nutrients, the requirements for the cultivation materials are also required to have the forming strength, air permeability and easy invasion of mycelium, etc. More than 70% of the cultivation materials of shiitake mushrooms are made of dense texture. Cottonseed hulls, oak sawdust, sawdust and other hard materials, these cultivation materials contain relatively high nutrient substances such as cellulose and protein, and the quality of mushrooms produced is good; in order to ensure its air permeability, large particle mixtures are often used, but The dense and hard particles make it difficult for mycelium to invade its scorpion, resulting in low utilization rate of raw m...

AI Technical Summary

Problems solved by technology

[0003] The main purpose of the present invention is to solve the problems existing in the existing shiitake mushroom compost treatment technology, and provide a process method for increasing production and modifying the hard compost of shiitake mushrooms. The process of heating, pressurizing and sudden disappearance of the hard pellets in the high-pressure container will cause the high pressure difference between the inside and outside of the hard pellets, and the moisture and air inside the pellets will overflow due to the sudden disappearance of the pressure, causing the hard wood to expand. Dense tissues become loose and porous, some cellulose substances are degraded, and some proteins are degraded into free amino acids
