Edible mushroom culture medium and preparation method thereof

Abstract

The invention provides an edible mushroom culture medium which comprises, by weight, 30-50 parts of biogas residues and biogas slurry, 30-50 parts of crop straws, 10-20 parts of grape pips and peels and a sterilizing agent with 0.5-2% of the volume-weight ratio. Hydrogen peroxide is adopted for the sterilizing agent, and the invention further provides a preparation method of the culture medium. The edible mushroom culture medium has the advantages that the grape pipes and peels comprise a large quantity of polyphenol substances and a large amount of linoleic acid and further have a certain bacteriostatic effect, so that more rich nutrition is provided for the culture medium, and the bacteriostatic effect enables the prepared culture medium not to be prone to being infected with infectious microbes; due to the fact that 35% of the hydrogen peroxide is selected and used for the sterilizing agent, the sterilizing effect is remarkable, in addition, due to the selection and use of the grape pips and peels, the culture medium is little infected with bacteria, in the process of high temperature sterilization, the culture medium is volatilized to generate water and oxygen, and no residue and contamination exist; a large amount of agricultural and stock farming waste such as the straws and the biogas residues and biogas slurry are further selected and used for the culture medium, so that reusing of the waste is achieved, and the culture medium meets the requirements of environmental protection and circular economy.

Description

technical field [0001] The invention relates to the technical field of edible fungus cultivation, in particular to an edible fungus culture medium and a preparation method thereof. Background technique [0002] China has a long history of cultivating edible fungi with a wide variety. The common ones are: shiitake mushrooms, straw mushrooms, mushrooms, fungus, white fungus, Hericium erinaceus, russula, boletus, etc. Edible fungi are delicious, nutritious, and rich in amino acids , can reduce cholesterol and high blood pressure symptoms, and the latest medical research shows that it also has anti-cancer effects, so the development of edible fungus breeding industry is a relatively promising industry. [0003] The main problem facing the current cultivation of edible fungi is how to master a reasonable culture medium formula to achieve a reasonable nutritional mix, good growth of the strains, and less bacterial contamination, and because of the current requirements of the circu...

AI Technical Summary

Problems solved by technology

At present, there are many such formulas, but the adaptability is general. For example, Chinese patent 2010102918274 discloses a preparation method of edible fungus culture medium, which mainly uses crop straw and fresh potato residue as raw materials, which not only solves the problem of the regeneration of straw and fresh potato residue Taking advantage of the problem, it provides a high-quality edible fungus culture medium, but there is still room for improvement
