Embodiment 2

[0064] The agricultural and forestry crop residues in Example 2 include bamboo chips with a particle size of 0.5-5mm, and the mixed powder includes bran.

Embodiment 3

[0065] The agricultural and forestry crop residues in Examples 3 and 4 include broad-leaved forest sawdust and bamboo debris with a particle size of 0.5-5 mm.

[0066] The mixed powder in Example 3 includes straw, corncobs and bran.

Embodiment 4

[0067] The mixed powder in Example 4 includes straw and corncobs.

[0068] The compressed block of Example 3 has the highest and most balanced nutrient content. According to experiments, the best effect can be achieved by using the formula of the medium compressed block of this embodiment.

[0069] In one embodiment, in terms of parts by mass, the culture medium for cultivating edible fungi includes: 300 parts of high-temperature and high-pressure cooking material leaching liquid after crushing straw, corncobs and bran, 30 parts of peptone, 5 parts of urea, sodium hydroxide 4 parts, 5 parts of yeast powder, 1 part of potassium dihydrogen phosphate, 2 parts of ammonium dihydrogen phosphate, 3 parts of magnesium sulfate, and 800 parts of sterile water.

[0070] The present invention also provides a method for preparing medium compressed block, comprising:

[0071] S1. Proportionately mix agricultural and forestry crop residues, mixed powder, lime powder and gypsum powder, and s...

Abstract

The invention discloses a culture medium compressed block formulation and a preparation method and culture method thereof. According to the culture medium compressed block formulation, a culture medium compressed block comprises a compressed block and an edible fungus cultivation culture solution; the compressed block comprises, by weight, 65-70% of agricultural and forestry crop residue, 20-25% of mixed powder, 1-5% of lime powder and 5-9% of gypsum powder; the agricultural and forestry crop residue comprises broad-leaved forest sawdust and/or bamboo debris; the mixed powder comprises one ormore of straw, corncob and bran. The preparation method of the culture medium compressed block comprises the steps of mixing the agricultural and forestry crop residue, the mixed powder, the lime powder and the gypsum powder to obtain a mixed material; conveying the mixed material into a drying cabin, heating, and controlling moisture; continuously carrying out heat preservation on the mixed material, conveying to a material inlet of a stamping machine, compressing to form a compressed block, wherein the compressed block is provided with through holes; adding the compressed block into a pressure container, injecting the edible fungus cultivation culture solution, draining, and airing to obtain the culture medium compressed block. The invention also provides a culture method of the culturemedium compressed block.

Description

technical field [0001] The invention relates to the technical field of edible fungus cultivation, in particular to a medium compressed block formula, a preparation method and a cultivation method thereof. Background technique [0002] The edible fungi in the wild environment are all formed by fungal growth in natural environments such as rotten wood and humus soil. In the early days of edible fungi cultivation, most of them were cultivated directly by placing wood sections in the open air. For the purpose of protecting forest resources, the cultivation of edible fungi using section wood has been banned in various places. [0003] At present, the cultivation of edible fungi mostly adopts the cultivation of bacteria in bagged bulk fully cooked medium. The sterilization time of bagged bulk fully cooked medium is long, and the proportion of nutrients lost by pyrolysis is high. In order to ensure the nutrients required for the growth cycle of edible fungi It is necessary to incr...
