Traditional Chinese medicine residue shiitake culture medium and preparation method thereof

Abstract

The invention discloses a traditional Chinese medicine residue shiitake culture medium and a preparation method thereof. The culture medium is prepared from the following raw materials in parts by weight: mulberry wood, a 7% dilute sulfuric acid solution, quartz sand, traditional Chinese medicine residue, ethanol, cottonseed hull, garlic straw, peanut shell, lime powder, pitch peat and a proper amount of water. The traditional Chinese medicine residue is subjected to liquid decoction and extraction, pulverized into smaller shapes, decocted and mixed with loose porous modified mulberry wood block, so that the effective components are indirectly transferred to the wood block; since most edible fungi grow in an environment with certain water quantity and favorable air permeability, the transfer of the extracting solution into the wood block effectively reduces the evaporative water, overcomes the defect that the nutrients can not be absorbed, and well keeps the shape of the culture medium.

Description

technical field [0001] The invention belongs to the technical field of edible fungus medium, and in particular relates to a traditional Chinese medicine dregs mushroom medium and a preparation method thereof. Background technique [0002] Mulberry is a perennial woody plant with the characteristics of easy germination, resistance to cutting and strong resilience. During the cultivation of mulberry trees, it is usually necessary to cut down the mulberry branches, especially the breeding of silkworms requires a large amount of fresh and tender mulberry leaves, and the mulberry trees need to be constantly pruned to achieve the freshness of the mulberry branches and new leaves. It is beneficial to reduce the occurrence of diseases and insect pests. The pruned branches are often directly burned as firewood or rotted in the corner of the field, which not only pollutes the environment but also wastes resources. As early as many years ago, mulberry branches were crushed into mulberr...

Problems solved by technology

[0005] Lentinus edodes is a kind of wood rot fungus, its growth is divided into two stages, one is the mycelium stage, the other is the fruiting body stage, at the same time, the mushroom must absorb the nutrients in the dissolved water, and most of the current mushroom culture medium raw materials Generally, they are paper scraps, cottonseed hulls, waste cotton dregs, corn stalks, corncobs, etc. Due to the constant water content of the medium, it is difficult for the nutrients of these raw materials to exist in a liquid or semi-liquid form, and a large part of them hinder The absorption and utilization of raw materials by shiitake mushroom mycelium, if the raw materials are crushed into smaller particles and made into a homogenized state, a large part exceeds the optimum water content of the medium, and at the same time hinders gas circulation, which is not conducive to the growth of shiitake mushrooms. The danger of breeding bacteria
