Embodiment 1

[0014] A method for preparing a cultivation substrate for straw mushrooms, comprising fermentation, packaging and sterilization, the specific steps are:

[0015] 1) Add vinegar grains, bagasse, fungus bagasse, straw, cottonseed hulls, bran, gypsum powder, lime, enzyme preparations, fermentation preparations, and water until the water content is 62%, stir evenly to form a mixture, and then mix the mixture Pile into a material pile with a width of 1.3m, a height of 1.5m, and an unlimited length. Air holes are opened on the material pile at an interval of 0.3m, covered with a sunshade net to keep heat and moisturize, and piled for fermentation for 13 days. Turn the pile once every 4 days to obtain the fermented product. In this step, the enzyme preparation can degrade the cellulose and lignin in the substrate into small molecular substances, improve the utilization rate of the substrate by edible fungi, improve the yield and quality of straw mushrooms, shorten the fermentation tim...

Embodiment 2

[0019] A method for preparing a cultivation substrate for straw mushrooms, the specific steps are: add vinegar grains, bagasse, fungus bagasse, straw, cottonseed hulls, bran, gypsum powder, lime, enzyme preparation, fermentation preparation in a formula amount, and add water until the water content is 65%, stir evenly to form a mixture, and then pile the mixture into a pile with a width of 1.3m, a height of 1.3m, and an unlimited length. Air holes are opened on the pile with an interval of 0.25m, and the sunshade net is covered to keep heat and moisturize. The pile is fermented for 12 days. Turn the pile once every 3 days to obtain the fermented product; adjust the water content of the fermented product to 65%, adjust the pH to 7.5, put the fermented product into a high-temperature-resistant plastic bag, 1kg per bag, and seal it at a pressure of 0.7 Kg / cm, sterilized at 135°C for 3.5 hours, and cooled to obtain the straw mushroom cultivation substrate. The cultivation substrate...

Embodiment 3

[0022] A preparation method of a cultivation substrate for straw mushrooms is as follows: the composition of the cultivation substrate and its parts by weight are: 18 parts of vinegar grains, 12 parts of bagasse, 22 parts of fungal bagasse, 12 parts of straw, 10 parts of cottonseed hulls, 6 parts of bran, 2 parts of gypsum powder, 1 part of lime, 0.002 part of enzyme preparation, 0.6 part of fermented preparation, above-mentioned enzyme preparation is cellulase, ligninase and active polypeptide, and its weight ratio is 1:0.8:0.02. Bagasse, fungus bagasse, straw, cottonseed hulls, bran, gypsum powder, lime, enzyme preparation, fermentation preparation, add water until the water content is 70%, stir evenly to form a mixture, and then pile the mixture into a width of 1m and a height of 1.2m , the stockpile of unlimited length, the space between the stockpile is 0.3m to open air holes, cover the sunshade net to keep warm and moisturize, stack and ferment for 10 days, turn the pile ...

Abstract

The invention discloses a preparation method of a culture medium for volvariella volvacea. The preparation method particularly comprises the following steps: adding water into 12-18 parts by weight of vinegar residues, 10-16 parts by weight of bagasse, 16-22 parts by weight of mushroom dregs, 12-18 parts by weight of straw, 6-10 parts by weight of cottonseed hull, 5-9 parts by weight of bran, 1-2 parts by weight of gypsum powder, 1-2 parts by weight of lime, 0.001-0.002 part by weight of an enzyme preparation and 0.5-0.9 part by weight of a fermentation preparation, performing uniform stirring, and stacking for fermentation; and adjusting the water content and the pH value of the fermentation broth, performing bagging, sealing bags, and then performing sterilization and cooling to obtain the volvariella volvacea culture medium. The preparation method has the following beneficial effects: the preparation method is simple, the preparation period is short, difficult-to-absorb macromolecular substances in the medium can be degraded into small molecular substances, worm eggs and part of infectious microbes are killed, and large-scale production is easy; and the culture medium enables the volvariella volvacea cultivation period to be short, and the cultured volvariella volvacea is dense, thick, uniform and ordered and has high commodity.

Description

technical field [0001] The invention relates to the technical field of edible fungus cultivation, in particular to a method for preparing a cultivation substrate for straw mushrooms. Background technique [0002] Straw mushroom is an edible fungus variety commonly cultivated in southern my country. Straw mushroom meat is fine and smooth, crisp and refreshing, and delicious. It is not only a good nutritional product on people's table, but also a traditional export commodity in my country. The mushroom polysaccharides and other substances contained in straw mushrooms have health effects such as improving human immunity, lowering cholesterol, and anti-tumor, and are favored by consumers at home and abroad. Straw mushroom is a kind of grass rot fungus, which has a strong ability to decompose cellulose. For a long time, mushroom farmers have used straw, wheat straw, waste cotton, and cottonseed hulls as the main raw materials to make straw mushroom cultivation materials. But al...
