Embodiment 1

[0040] The specific steps for fermenting edible mushroom culture material by adopting culture material secondary fermentation process of the present invention are as follows:

[0041] Step I: preparation of compost, the raw materials of compost include 2000kg of wheat straw, 250kg of cake, 10kg of animal excrement, 75kg of superphosphate, 30kg of urea, 75kg of gypsum, 75kg of limestone and 10kg of fungicide. Feces need to be collected in advance, dried in the sun, crushed and stored for use before use (in the actual batching, the raw materials can be properly adjusted according to actual needs);

[0042] Step II: pre-fermentation, the pre-fermentation process comprises the steps:

[0043] (1) Pre-wetting and pre-stacking of raw materials: pre-stacking of forage and animal manure after pre-wetting;

[0044] (2) Building a heap: choose a place with a higher terrain and close to the mushroom house, and disinfect it with 5% lime water before building the heap; Lay the forage on th...

Embodiment 2

[0062] Such as figure 2 As shown, the difference between this embodiment and Embodiment 1 is that in this embodiment, the heating mechanism 16 is a stove heating mechanism 16, and the stove heating mechanism 16 includes a stove with a filling port and a stove for exhausting smoke from the stove. The vertical smoke exhaust passage 19, the steam pipe 2 is covered with a thermal insulation cover 18, and the thermal insulation cover 18 runs through the smoke exhaust passage 19 of the stove heating mechanism 16.

[0063] In this embodiment, heating through the stove breaks the restriction of whether the electricity is on or not, and is not limited by the fuel in the stove. The agricultural waste generated during the cultivation of edible fungi can be reused, realizing a good ecological cycle. . The thermal insulation jacket 18 outside the steam pipe 2 can heat the steam pipe 2 at high temperature. Since the steam enters the steam pipe 2 and the temperature is relatively high, the...

Abstract

The invention relates to the technical field of edible mushroom cultivation, and particularly discloses a secondary fermentation process of a culture material. The secondary fermentation process comprises the steps of preparation of the culture material, primary fermentation and secondary fermentation, wherein the secondary fermentation comprises the following steps: (1) a primary heating stage: heating a mushroom house to the temperature of 50-53 DEG C by adopting mobile heating equipment, and controlling the temperature for 4-8 hours; (2) a secondary heating pasteurization stage: supplying steam to the mushroom house to carry out secondary heating by adopting the mobile heating equipment, when the temperature of the mushroom house reaches 62-64 DEG C, carrying out heat preservation for 8hours, stopping supplying the steam and sealing the mushroom house, when the central temperature of the primary fermentation material reaches 72-75 DEG C, continuing to carry out heat preservation for 4 hours, and then carrying out ventilating; (3) a temperature control decomposition stage: after pasteurization is finished, when the temperature of the mushroom house is reduced to 42-45 DEG C, increasing the ventilation quantity, when the temperature of the material is reduced to 30 DEG C, keeping the temperature of the mushroom house at 30 DEG C, and carrying out heat preservation for 8-12 hours so as to obtain the culture material. According to the secondary fermentation process of the culture material, the fermentation conditions are convenient to adjust, and the prepared culture material is sufficient in nutrition and is beneficial to material eating and germination of strains after sowing.

Description

technical field [0001] The invention relates to the technical field of edible fungus cultivation, in particular to a secondary fermentation process of compost. Background technique [0002] Edible mushrooms refer to mushrooms (large fungi) with huge fruiting bodies and edible mushrooms, commonly known as mushrooms. There are more than 350 kinds of edible fungi known in China, most of which belong to Basidiomycotina. , Ganoderma lucidum, Cordyceps, Truffle, Bailing mushroom and boletus etc. Edible fungi are rich in protein and amino acids, and their content is several to dozens of times that of ordinary vegetables and fruits; in addition, edible fungi contain biologically active substances such as: polymer polysaccharides, β-glucose and RNA complexes, natural organic germanium , nucleic acid degradation products, cAMP and triterpenoids have important utility value for maintaining human health. Therefore, more and more people begin to pay attention to edible fungi, and the c...
