Wood rot type edible fungi culture medium and preparation method thereof

Abstract

The invention belongs to the field of organic matter utilization and particularly relates to a wood rot type edible fungi culture medium and a preparation method thereof. The wood rot type edible fungi culture medium is composed of the following components in percentage by weight: 45-75% of radix paeoniae rubra residue, 10-30% of xylitol residue, 5-20% of bran, 0-20% of cottonseed hull, 1-10% of corn flour, 0.2-1% of calcium carbonate and 0.5-1% of gypsum. Lime milk and water are added in the medium, the pH is regulated to 7-10, and the water content is controlled to 55-77 wt% of the total weight. The wood rot type edible fungi culture medium germinates mycelium quickly, the mycelium grows vigorously, and the bacterial contamination rate can be greatly reduced. The edible fungi produced by the wood rot type edible fungi culture medium disclosed by the invention have various nutritional characteristics of edible fungi produced by a common culture medium and have high edible value and medicinal value.

Description

[0001] technical field

[0002] The invention belongs to the field of organic matter utilization, and in particular relates to a wood rot type edible fungus cultivation substrate and a preparation method thereof. Background technique

[0003] Edible fungi are not only delicious, but also rich in nutrition, containing a large amount of amino acids, multivitamins and a variety of physiologically active mineral elements, and are often called healthy food by people. There are various varieties of edible fungi with different characteristics. Only through cultivation and management can the fruiting bodies of various edible fungi be produced for people to enjoy, in order to show their edible value, medicinal value and economic value. Therefore, the cultivation of edible fungi is of great significance .

[0004] Edible fungi can be divided into wood rot type and grass rot type according to their growth habits. Wood-rot edible fungi are a type of edible fungi with woody materials a...
