Problems solved by technology

[0003] Strains are one of the important means of production in the production of straw mushrooms. The original species are directly used for cultivation and production. The traditional original species mostly use grain compost in non-cotton production areas, which is costly and difficult to disperse after sterilization. The original species is easy to aging, short shelf life
When cultivated in a large area, it is easy to attract rodents, and spraying rodenticide will increase environmental pollution

[0021] The present invention also provides a kind of preparation method of above-mentioned straw mushroom production medium, comprising the following steps:

[0022] a. Take the raw materials by weight, crush the cow dung, and crush the corncobs into particles with a particle diameter of ≤5mm, and set aside;

[0023] b. Mix corncobs, cow dung, cottonseed husks, bran, soybean meal and lactic acid, add water until the water content is 50-70%, seal and ferment for 6-7 days, turn over once every 2 days;

[0024] c. After step b is completed, add quicklime and sodium bicarbonate while stirring, then add cellulase and hemicellulase, adjust the water content of the medium to 60-70%, put it into a strain bottle, sterilize at high temperature, and prepare Straw mushroom culture medium was obtained.

[0025] Wherein, in the preparation method of the above-mentioned straw mushroom production medium, the fermentation temperature in step b is 15-18°C.

Abstract

The invention belongs to the technical field of technologies for growth media for edible mushrooms and particularly relates to a production strain growth medium for Volvariella volvacea and a preparation method of the production strain growth medium. A grain growth medium is usually used for cultivating the Volvariella volvacea in the prior art and has the disadvantages that the cost is high, the growth medium is not dispersed easily after sterilization, stock seeds are prone to aging and the storage life is short. According to the growth medium for the Volvariella volvacea and the preparation method of the growth medium, corncob is taken as a main raw material, bran, cow dung, cottonseed hulls, soybean meal and other materials are added, and the growth medium is prepared through lactic acid fermentation. Agricultural by-products such as the corncob, the cow dung, the cottonseed hulls and the like are used sufficiently, the cost is saved, the growth medium is dispersed easily after sterilization, the strain has long storage life, germination and uptake are fast after inoculation, and the final fruiting conversion rate is high; besides, rodent damage can be eliminated during fruiting, use of rodenticides is avoided, the safety of the Volvariella volvacea is guaranteed, and environmental damage is avoided.

Description

technical field [0001] The invention belongs to the technical field of edible fungus medium, and in particular relates to a culture medium for producing straw mushrooms and a preparation method thereof. Background technique [0002] Straw mushroom, also known as Orchid Ru, Chinese Mushroom, etc., belongs to Basidiomycotina, Phytomycota, Agaricaceae, Amanitaceae, and Straw Mushroom in taxonomy. Straw mushroom is a kind of grass-rot edible fungus. It likes temperature and humidity. It grows saprophytic on fibrous substrates such as dung grass and straw, and obtains nutrients by decomposing cellulose, hemicellulose and other substrates. It is the fastest harvesting among all edible fungi. , one of the most abundant cultivation raw materials, its delicious taste, rich nutrition, food and medicine, deeply loved by consumers. my country started artificial cultivation 300 years ago, and my country's straw mushroom output ranks first in the world at present, accounting for more tha...
