Problems solved by technology

As far as the current utilization of potato residues is concerned, both the production of single-cell protein feed and the extraction of natural products are difficult to be widely used in actual production. Potato residues are idle, causing waste of resources and serious pollution to the environment

Abstract

The invention relates to a method for processing a culture medium of edible fungi. The method comprises the steps: airing crop straw, pulverizing the aired crop straw with a pulverizer so as to obtainpulverized straw with a length of 1 cm, mixing fresh potato residues with a water content of 80% with the pulverized crop straw at a mass ratio of (3-5):(7-5) in term of dry weight, adding 2% of gypsum or calcium carbonate and 0.1% of carbendazol powder or 0.1% of thiophanate-methyl and other fungicides, performing even stirring in a stirrer, adding lime water so as to adjust the pH value of themixed materials to 6-8, and pouring the mixed materials obtained in the two steps into polypropylene plastic bags with the specification of 17 cm X 35 cm X 0.045 cm in a mechanical or manual bagging mode, wherein the bag height is about 17-23 cm; and performing sterilization at normal temperature and normal pressure for 8-12 hours or autoclaved sterilization for 2-3 hours. The culture medium is applied to cultivation and production of edible fungi, comprehensive utilization of the potato residues and crop straw is achieved, and both solution of the problem of potato residue treatment and supply of a culture medium for producing high-quality edible fungi are achieved.

Description

technical field [0001] The invention relates to an edible fungus cultivation technology, in particular to a method for producing edible fungus culture medium by using potato residue and straw as raw materials. Background technique [0002] The invention is a technology for producing high-quality edible fungus culture medium in the technical field of agricultural production. Edible fungi are large fungi that can be eaten by humans. There are more than 350 kinds of edible fungi known in China, most of which belong to the Basidiomycotina. And bolete, etc.; a few belong to Ascomycotina (Ascomycotina), including: Morchella, saddle fungus, truffle and so on. There are many species and quantities growing in mountainous areas and woodlands, such as shiitake mushroom, side ear, fungus, white fungus, Hericium erinaceus, red mushroom and boletus. Straw mushrooms, mushrooms, etc. grow on fields, roadsides, grasslands and haystacks. High-temperature fruit-bearing fungi grow more in t...
