Embodiment 1

[0011] A method for preparing an edible fungus culture medium. The culture medium includes the following raw materials in proportion by weight: 60 parts of cottonseed hulls, 10 parts of corn cobs, 10 parts of wheat bran, 3 parts of lime powder, 5 parts of soybean stems, and 0.5 parts of sucrose; Water the cottonseed husks and corncobs to pre-wet them, mix them evenly, pile the pre-wet cottonseed husks and corncobs into a pile, and cover them with a piece of plastic film soaked in 5% lime water. After 2 days, turn the piles and cover them Get up and continue to ferment, and repeat this twice. During the mixed fermentation process of cottonseed hulls and corn cobs, keep the temperature of the mixed fermented material not exceeding 75° C. to obtain fermented clinker. Weigh the mixed fermented clinker and other ingredients according to the ratio, spread them layer by layer, and mix them twice with a mixer until they are evenly mixed.

Embodiment 2

[0013] A method for preparing an edible fungus culture medium. The culture medium includes the following raw materials in proportion by weight: 70 parts of cottonseed hulls, 20 parts of corn cobs, 30 parts of wheat bran, 5 parts of lime powder, 15 parts of soybean stems, and 1 part of sucrose; Water the cottonseed hulls and corn cobs to pre-wet them, mix them evenly, pile up the pre-wet cotton seed hulls and corn cobs, cover them with a piece of plastic film soaked in 5% lime water, and after 5 days, turn them over and cover them Get up and continue to ferment, and repeat this 3 times. During the mixed fermentation process of cottonseed hulls and corn cobs, keep the temperature of the mixed fermented material not exceeding 75° C. to obtain fermented clinker. After the clinker and other ingredients after mixed fermentation are weighed according to the proportion, spread out layer by layer, turn over and mix 3 times with a mixer, and mix evenly.

Embodiment 3

[0015] A method for preparing an edible fungus culture medium. The culture medium includes the following raw materials in proportion by weight: 65 parts of cottonseed hulls, 15 parts of corn cobs, 20 parts of wheat bran, 4 parts of lime powder, 11 parts of soybean stems, and 0.6 parts of sucrose; Water the cottonseed husks and corncobs to pre-wet them, mix them evenly, pile the pre-wet cottonseed husks and corncobs into piles, and cover them with a piece of plastic film soaked in 5% lime water. After 3 days, turn the piles and cover them Get up and continue to ferment, and repeat this twice. During the mixed fermentation process of cottonseed hulls and corn cobs, keep the temperature of the mixed fermented material not exceeding 75° C. to obtain fermented clinker. Weigh the mixed fermented clinker and other ingredients according to the ratio, spread them layer by layer, and mix them twice with a mixer until they are evenly mixed.

Abstract

The invention discloses a preparation method of a culture medium for edible fungi, belongs to the technical field of edible fungus production and aims at providing a preparation method of a culture medium for edible fungi, which is simple and feasible as well as capable of ensuring that the water of the whole culture medium is uniformly distributed. In order to solve the technical problem, the invention adopts the technical scheme as follows: the culture medium comprises the following raw materials in parts by weight: 60-70 parts of cotton seed hulls, 10-20 parts of corn cobs, 10-30 parts of wheat bran, 3-5 parts of lime powder, 5-15 parts of soybean straws and 0.5-1 part of cane sugar; and the preparation method comprises the steps of watering to pre-wet the cotton seed hulls and the corn cobs, uniformly mixing, stacking the pre-wet cotton seed hulls and corn cobs, covering the cotton seed hulls and the corn cobs by using a plastic film soaked with 5% lime water, and overturning after 2-5 days; then, covering to further ferment, and repeating in such a way for 2-3 times, and keeping the temperature of the mixed fermentation material not higher than 75 DEG C in the mixed fermentation process of the cotton seed hulls and the corn cobs to obtain fermented clinker; and after weighing the mixed fermentation clinker and other ingredients according to a certain ratio, spreading layer by layer, stirring by using a stirrer for 2-3 times, and uniformly mixing.

Description

technical field [0001] The invention discloses a method for preparing an edible fungus culture medium, which belongs to the technical field of edible fungi production. Background technique [0002] Edible fungi are a kind of saprophytic fungi, which cannot use solar energy for photosynthesis, and rely entirely on the nutrients in the medium for growth and development. Among the nutrients, carbon-containing substances are the most important, followed by nitrogen-containing substances and inorganic salts. [0003] With the rapid development of the economy, people's living standards are improving day by day, and the consumption of edible fungi is increasing, which greatly promotes the production scale and development speed of edible fungi. The culture material of fungi refers to the carrier that provides nutrients for the growth of fungi. [0004] The existing culture medium for edible fungi is mainly composed of straw, corn stalks, cottonseed husks, corncobs and other crop s...
