Embodiment 1
[0019] According to needs, choose volcanic rock particles with a particle size of 0.5-3.0 cm. The porosity, color, and specific gravity of the volcanic rock are not limited. The particle shape is preferably nearly spherical, and other shapes can also be used directly.
[0020] This scheme is used to make mother species, original species and cultivated species of various edible fungi. The mother species chooses volcanic stone particles with a diameter of 0.1-0.5cm, the original species chooses volcanic stone particles with a diameter of 0.5-1.5cm, and the cultivated species chooses volcanic stone particles with a diameter of 1.0-3.0cm. For the long-term preservation of the test tube parent species, choose 0.2-0.5cm volcanic stone particles, the height of the test tube is 1 / 2 of the test tube length, and the liquid height is 1-2cm.
[0021] Nutrient solution formula: natural materials: 20-80g of bran, or 100-150g of rice bran, or 50-100g of wheat grain, or 50-100g of corn kernel...
Embodiment 2
[0026] This scheme is used to make the original species and cultivated species of various edible fungi.
[0027] Volcanic stone: choose volcanic stone particles with a diameter of 1-3cm.
[0028] Auxiliary solid medium formula: sawdust powder, or grass powder, or cottonseed hull powder, 80% to 90%; bran 20% to 25%, or rice bran 20% to 25%, or corn flour 5% to g%, Or soybean powder 5% to 8%; gypsum powder 1%; calcium carbonate powder 1%. The above materials need to pass through a fine sieve of 10 to 20 meshes, and the fine powder is used as raw material.
[0029] Preparation method of auxiliary solid medium: Weigh various raw materials according to the formula, mix the dry materials 2-3 times, add water, the ratio of material to water is 1:1.1-1.4, mix well 2-3 times, and set aside.
[0030] The preparation method of edible fungus strains: the ratio of volcanic stone to auxiliary solid medium is 1:0.2-0.3 by volume, and the dry volcanic stone and the auxiliary solid medium mi...
Embodiment 3
[0033] The auxiliary solid medium in scheme 2 plus the nutrient solution mix in scheme 1, the ratio of material to water is 1:1.1-1.4. Stir with volcanic stone again, the volume ratio of volcanic stone and auxiliary solid medium is 1:0.2~0.3, so that the surface of each volcanic stone particle is evenly covered with a layer of 1~2mm thick auxiliary solid medium, bottled or bagged, The amount of material is not limited, and it is determined according to actual needs. Seal the mouth of the bottle or bag, sterilize, inoculate, cultivate, and obtain usable edible fungus strains after the bag or bottle is full of mycelium.
