Problems solved by technology

[0002] Most of the culture substrates of the original species and cultivated species of edible fungi use natural plant materials as the substrate, such as cottonseed hulls, sawdust / wood particles, corncobs, grass powder, grains, bamboo chips / nodes, etc. The mycelium of the shape is broken, and the survival rate after inoculation is not high
[0003] Natural plant material is used as the seed matrix, the inoculation block is easy to be crushed, and it is easy to cause inoculation pollution, the survival rate of mycelium is reduced, the strain is easy to lose water and aging, the medium is easy to lose water in the container, and the mycelium is easy to age. The storage time is very limited, etc.

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.

Abstract

The invention discloses a method for cultivating edible mushroom strains by using lava. The method includes that the lava is used as a matrix, a nutrient solution and powdery excipients are added, edible mushroom strains suck as stock seeds and cultivation seeds are cultivated, and mycelia grow on the surface of the granular lava and also fill gaps inside the lava. By the method, the mycelia grow vigorously, strain preservation time is up to more than one year, the strains can bear extruding and striking in the process of inoculating, inoculating survival rate is high, inoculating pollution rate is low, and fruiting bodies are high in yield.

Description

technical field [0001] The invention belongs to the technical field of microbes, and in particular relates to a method for cultivating edible fungus strains with natural porous material volcanic rock. Background technique [0002] Most of the culture substrates of the original species and cultivated species of edible fungi use natural plant materials as the substrate, such as cottonseed hulls, sawdust / wood particles, corn cobs, grass powder, grains, bamboo chips / nodes, etc. The mycelium of the shape is broken, and the survival rate after inoculation is not high. [0003] Natural plant material is used as the seed matrix, the inoculation block is easy to be crushed, it is easy to cause inoculation pollution, the survival rate of mycelium is reduced, the strain is easy to lose water and aging, the medium is easy to lose water in the container, and the mycelium is easy to age. The storage time is very limited and so on. Contents of the invention [0004] The object of the p...
