Embodiment 1

[0038] Example 1 Prepare edible fungus culture medium with cotton stalks and cultivate Pleurotus ostreatus, implement according to the following steps:

[0039] (1) Pulverization: the cotton straw raw material is separated from the skin core and the skin material, core material and separation material obtained after removing peaches, leaves and twigs are respectively pulverized to a particle size of 3-8 mm; the cotton seed hulls are crushed to a particle size of 3 mm -8mm;

[0040] (2) material preparation: the leather material, core material, separation material obtained in step (1), or any ratio mixture thereof in them are used as cotton straw powder and cottonseed hull powder and fine soil and wheat bran to prepare materials in proportion respectively, The proportion by weight is 60-70 parts of cotton straw powder, 15-25 parts of cottonseed hull powder, 10-15 parts of fine soil, and 5 parts of wheat bran;

[0041] (3) soaking: soaking the cotton straw powder and cottonseed...

Embodiment 2

[0047] Example 2 Prepare edible fungus culture medium with cotton stalks to cultivate shiitake mushrooms, and implement according to the following steps:

[0048] (1) Pulverization: directly pulverize the cotton straw raw material without separating the skin and core to obtain an unseparated material with a length of 4-6 mm; pulverize the cotton seed husk to a particle size of 4-6 mm;

[0049] (2) Raw material preparation: the step (1) cotton stalk powder and cottonseed husk powder and fine soil, wheat bran are prepared in proportion respectively, and its weight ratio is 50-60 parts of cotton stalk powder, 10 parts of cottonseed husk powder -15 parts, 5-10 parts of fine soil, 4 parts of wheat bran;

[0050] (3) soaking: soaking the cotton straw powder and cottonseed hull powder obtained in step (2) with water, absorbing water to make them swell; it is convenient for the detonation treatment in the next step to fully degrade the various nutrients in the cottonseed hull;

Embodiment 3

[0056] Example 3 Prepare edible fungus culture medium with cotton stalks to cultivate Flammulina velutipes, implement as follows:

[0057] (1) Crushing: Part of the cotton straw raw material is separated from the skin and core, and the leather, core material and separation material obtained after removing peaches, leaves, and twigs are respectively crushed to a particle size of 3-8 mm, and the other part is not separated from the skin and core. Directly crush to obtain unseparated material with a length of 4-6mm; crush the cottonseed husk to a particle size of 3-8mm;

[0058] (2) Raw material preparation: use step (1) gained leather material, core material, separated material, unseparated material or any ratio mixture in them as cotton straw powder and cottonseed hull powder and fine soil and wheat bran respectively in proportion Prepare materials, and its weight ratio is 55-65 parts of cotton straw powder, 15-20 parts of cottonseed hull powder, 8-12 parts of fine soil, and 4 ...

Abstract

Belonging to the field of edible fungi, the invention relates to a method for preparation of an edible fungus culture medium from cotton straw. The method includes: (1) crushing: conducting skin-core separation on the cotton straw, and removing cotton bolls, leaves and twigs, then crushing the obtained skin material, core material and separated material, or conducting crushing without skin-core separation, and crushing cottonseed hulls to a particle size of 3-8mm; (2) material preparation: preparing crushed cotton straw, crushed cottonseed hulls, fine soil and wheat bran separately according to a weight part ratio of (50-70):(10-25):(5-15):(3-5); (3) soaking: soaking the crushed cotton straw and the crushed cottonseed hulls; (4) mixing; (5) detonation treatment: placing the mixture in a closed pressure vessel, introducing high-pressure steam, and maintaining an air pressure of 1.6-2.5MPa for 5-15min, releasing materials and performing steam pressure relief to atmospheric pressure within 60-75ms so as to explode the materials; (6) fertilizer adding: by weight, adding 0.5-2% of calcium superphosphate and 0.1-0.5% of urea; and (7) bagging and sterilization. The method provided by the invention greatly reduces the cost and increases yield, and is suitable for popularization.

Description

technical field [0001] The invention belongs to the field of edible fungus culture medium, in particular to a method for preparing edible fungus culture medium by using cotton stalks. Background technique [0002] Edible fungi are not only delicious, but also low in energy and fat, and rich in protein, dietary fiber, vitamins and other nutrients. They are developing into the third type of food besides plant food and animal food, that is, fungal food. In addition, edible fungi are also one of the sources of various natural products such as functional polysaccharides and terpenoids, which have significant effects in improving human immune function, preventing and treating various chronic diseases, and anti-aging. Therefore edible fungus is more and more subject to the favor of consumers in general, and market demand is constantly increasing. [0003] On the other hand, China is a large agricultural country, and there are many types and huge quantities of waste in agricultural...
