preparation example Construction

[0031] As another aspect of the present invention, a method for preparing a wood rotten edible fungus culture stick is provided, wherein the preparation method includes:

[0032] S1. Mixing and soaking the salix sawdust with an alkali solution with a predetermined pH value, then stacking and fermenting, and drying the salix sawdust after the alkali treatment after a predetermined period of time;

[0033] S2. Mixing Salix salix sawdust after alkali treatment with bran and nitrogen-containing additives to obtain the wood rot edible fungus culture medium;

[0034] S3. Mix the wood rot edible fungus culture medium with water and then sterilize to obtain the wood rot edible fungus culture stick.

[0035] After step S1, the tannins in the salix sawdust can be neutralized, which is more conducive to the growth of wood-rot edible fungi.

[0036] Preferably, the pH value of the alkaline solution is not less than 12. For example, salix sawdust can be treated with alkali by using lime ...

Embodiment 1

[0045] S1, using lime water with a pH value of 12 to carry out mixing-soaking-heap fermentation of Salix sawdust, and drying the Salix sawdust after alkali treatment after 5 days;

[0046] S2, take by weighing 800g alkali-treated salix sawdust, 185g bran and 15g and mix evenly to obtain a wood rot edible fungus culture medium;

[0047] S31. Add 1100g of water to the 1000g of wood rot edible fungus culture medium obtained in step S2 to obtain the mixture, bag the mixture to obtain the semi-finished product, put the semi-finished product into an autoclave, and sterilize at 0.5Kg / m 3 Carry out high-temperature sterilization treatment under high pressure, the temperature of high-temperature sterilization is 115 ° C, and the duration is 8 hours, wherein, the high-pressure sterilization cabinet is a steel sealing body of 5 cubic meters;

[0048] S32. Lower the temperature of the semi-finished product after step S31 to 55° C. to obtain the wood rot edible fungus culture stick.

Embodiment 2

[0050] Utilize the preparation method provided in Example 1 to prepare wood-rot edible fungus culture sticks, the difference is that: in step S1, the pH value of lime water is 13, and the treatment time is 4 days; in step S2, salix sawdust The quality of the bran is 900g, the quality of the bran is 80g, and the quality of the soybean meal is 20g; in step S31, the quality of the water added is 1200g, and the pressure in the high-temperature sterilization cabinet is 0.5Kg / m 3 , the temperature is 110°C, and the duration is 6h; in step S32, the temperature is lowered to 45°C.

Abstract

The invention provides an edible wood rotting fungus culture medium which comprises salix psammophila wood flour subjected to alkaline treatment, bran and a nitrogen-containing additive. The invention further provides an edible wood rotting fungus culture bar and a preparation method thereof. The edible wood rotting fungus culture medium provided by the invention mainly comprises the salix psammophila wood flour subjected to alkaline treatment, which is very easily available in a desert area, so that the cost of the culture medium is very low.

Description

technical field [0001] The present invention relates to the field of cultivating wood-rot edible fungi, in particular to a wood-rot edible fungus culture medium, a wood-rot edible fungus culture stick made from the wood-rot edible fungus culture medium, and the wood-rot edible fungus culture stick method of preparation. Background technique [0002] Culture medium is needed when cultivating edible fungi, and the common culture medium for edible fungi is PDA medium. [0003] PDA medium was prepared from potato, glucose and agar. Overall, the cost of PDA media is high. Contents of the invention [0004] The purpose of the present invention is to provide a wood-rot edible fungus culture medium, a wood-rot edible fungus culture stick made from the wood-rot edible fungus culture medium and a preparation method of the wood-rot edible fungus culture stick. The cost of the wood rot edible fungus culture medium is relatively low. [0005] In order to achieve the above object, t...
