Problems solved by technology

[0005] The purpose of the present invention is to solve the problem that the viscosity of the entire medium is increased and compacted after high-temperature sterilization of components rich in protein and starch in the medium, resulting in small porosity and poor air permeability of the medium. The present invention provides an edible The preparation method of the bacteria culture medium, the method pre-extrudes the easily hardened grain materials into cylindrical particles with a diameter of 2-4 mm and a length of 5-10 mm, and then mixes them with straw materials. This preparation method is suitable for various Preparation of Different Edible Fungi Medium

Embodiment 1

[0027] Embodiment 1: Pleurotus eryngii cultivation:

[0028] Step 1: Materials and Recipe

[0029] 25 parts of wood chips, 20 parts of corncobs, 15 parts of bagasse, 23 parts of bran, 5 parts of soybean meal flour, 10 parts of corn flour, 1 part of calcium carbonate, and 1 part of lime powder.

[0030] Step 2: Granulation and mixing

[0031] Firstly, the grain raw materials such as bran, soybean meal powder and corn flour are mixed evenly according to the ratio in the formula, and input into the granulation equipment, and made into granulation equipment with a diameter of 2-4mm and a length of 5-5mm under the action of high-temperature steam at 110-130°C in the equipment 10mm cylindrical granules are ready for use, with a water content of 12% to 15%; wood chips, corncobs, and bagasse are poured into the mixer according to the formula ratio and fully mixed, then the water content is adjusted to 68% to 70%, and then added to the grain raw materials according to the formula rati...

Embodiment 2

[0051] Embodiment 2: Flammulina velutipes cultivation:

[0052] Step 1: Materials and Recipe

[0053] 30 parts of wood chips, 20 parts of corncobs, 10 parts of cottonseed hulls, 15 parts of bran, 10 parts of rice bran, 13 parts of corn flour, 1 part of calcium carbonate, and 1 part of lime powder.

[0054] Step 2: Granulation and mixing

[0055] First, mix the grain raw materials such as bran, rice bran and corn flour evenly according to the proportion in the formula, and input them into the granulation equipment, and make them into granulation equipment with a diameter of 2-4mm and a length of 5-10mm under the action of high-temperature steam at 110-130°C in the equipment. The cylindrical granules are ready for use, with a water content of 12% to 15%; wood chips, corncobs, and cottonseed husks are poured into a mixer according to the proportion of the formula and fully mixed, then the water content is adjusted to 68% to 70%, and then the grain raw materials are added accordi...

Abstract

The invention discloses a preparation method of an edible mushroom culture medium. The preparation method comprises the following steps: extruding a grain material into cylindrical particles with diameters of 2-4mm and lengths of 5-10mm, then uniformly mixing with a straw material, adding calcium carbonate and lime powder, adding clear water to adjust the water content while stirring, adding tap water after uniformly and fully mixing all the materials, and finally enabling the water content to reach 64-67 percent and pH to reach 8-10, wherein the grain material is one or more of bean pulp, corn kernels, bran and rice bran; and the straw material is one or more of wood flour, corn kernels, bagasse and cotton seed hull. Compared with a conventional culture medium, the culture medium provided by the invention has the advantages that the mycelium culture period and the fruiting period are shortened, mycelium is thicker and stronger in, and the yield is stably improved.

Description

technical field [0001] The invention relates to a preparation method of edible fungus culture medium, specifically, grain materials are first extruded into granules and then mixed with straw materials to form a preparation method suitable for various edible fungus culture mediums. Background technique [0002] The cultivation cycle and yield quality of edible fungi are closely related to the physical state of the cultivation compost, and are even decisive factors, which directly affect the degree of mycelium decomposition of the culture mechanism and the accumulation of mycelium nutrients, thereby affecting yield and quality. The main research of the invention is the influence of formula materials on the physical state index of compost after being processed by special process. [0003] At present, most of the materials used for the cultivation of edible fungi include wood chips, cottonseed hulls (husks), corn cobs, bagasse, bean stalk powder, bran, corn flour, calcium carbon...
