A medium compressed block formula and its preparation method and cultivation method

Abstract

The invention discloses a medium compressed block formula, a preparation method and a cultivation method thereof. The medium compressed block formula, the medium compressed block includes compressed block and edible fungus culture medium; by weight percentage, the compressed block includes: agricultural and forestry crop residue 65%-70%, mixed powder 20%-25%, lime powder 1%-5% and gypsum powder 5%-9%; agricultural and forestry crop residues include broad-leaved forest sawdust and / or bamboo debris; mixed powder includes one or more of straw, corncobs and bran. The preparation method of medium compressed block comprises: mixing agricultural and forestry crop residues, mixed powder, lime powder and gypsum powder to obtain a mixed raw material; transferring the mixed raw material into a drying cabin, heating, and controlling moisture; continuing to keep the mixed raw material warm Transfer to the feed port of the punching machine, compress and form into a compressed block, and the compressed block has a through hole; put the compressed block into a pressure vessel, inject the edible fungus cultivation culture solution, drain and dry, and obtain a medium compressed block. The invention also provides a culture medium compression block culture method.

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...

AI Technical Summary

Problems solved by technology

The cultivation of traditional edible fungi is greatly affected by the natural environment and climate, and the production efficiency is low, which affects the enthusiasm of farmers for planting; and some varieties are restricted by the regional climate environment and cannot be cultivated in the whole region, and the current technology cannot effectively keep fresh for a long time (without adding chemical substances to keep fresh) ) state, long-distance transportation costs are high, and consumption and waste are large, leading to a vicious circle in which the production profit of the edible fungus cultivation industry is not high, but consumers consume at high prices and low quality
