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 preparation method of a culture medium of edible fungi, which comprises the following steps: airing crop straw and pulverizing the crop straw by a pulverizer, wherein the length of the pulverized straws is 1cm; proportioning fresh potato pulp with the water content of 80% to the pulverized crop straw in dry weight into 3-5:7-5; adding gypsum or calcium carbonate of 2%, a bactericide such as carbendazim powder of 0.1% or thiophanate methyl of 0.1%, and the like; stirring evenly in a stirrer; adding lime water for adjusting the pH of the mixed materials into 6-8; filling the mixed materials treated in the two steps by a mechanical or manual bagging method into polypropylene plastic bags of which the specification is 17cm*35cm*0.045cm and the height of the bag is about 17-23cm; and sterilizing at normal temperature and pressure for 8-12 hours or autoclaving for 2-3 hours. The invention is used for culturing and producing the edible fungi, comprehensively utilizes the potato pulp and the crop straw, solves the problem of handling the potato pulp, and provides the culture medium for producing high-quality edible fungi.

Description

technical field [0001] The invention relates to an edible fungus cultivation technology, in particular to a method for producing edible fungus medium by using potato dregs and straw as raw materials. Background technique [0002] The invention is a technology aimed at 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 Basidiomycotina. and boletus, etc.; a few belong to Ascomycotina (Ascomycotina), including: morel, saddle fungus, truffle, etc. There are many types and quantities that grow in mountainous areas and woodlands, such as shiitake mushrooms, pleurotus, fungus, white fungus, Hericium erinaceus, russula and boletus. In the fields, roadsides, grasslands and haystacks, straw mushrooms and Tricholoma edodes grow. High-temperature fruiting fungi grow more in the south; low-t...
