Black fungus bag material containing pine sawdust and preparation method of bag material

Abstract

The invention provides a black fungus bag material containing pine sawdust and a preparation method of the bag material. The black fungus bag material consists of the following components in percentage by dry weight: 1-30 percent of pine sawdust, 50-80 percent of mixed wood sawdust, 18 percent of bran, 1 percent of gypsum powder and the balance of water for achieving the water content of 60-65 percent. The preparation method comprises the following steps: firstly, treating the pine sawdust, namely blending the pine sawdust into 2-3% lime water to kill harmful bacteria to ensure that the water content reaches 65 percent, stacking for fermenting, turning when the material temperature rises to above 60 DEG C, and then turning once every other 4-5 days, totaling in turning three to four times; secondly, preparing a culture material, namely adding the weed wood sawdust, the treated wine sawdust, the bran and the gypsum powder according to proportions according to the formula requirements; finally stirring and bagging, namely uniformly stirring the raw materials added according to the proportions, adding water till the water content is 60-65 percent, and bagging; sterilizing, inoculating, fruiting and harvesting according to the conventional bag material. According to the black fungus bag material and the preparation method provided by the invention, the black fungus is cultured by using the pine sawdust to substitute partial weed wood sawdust, so that the raw material source for cultivating the black fungus is broadened, the forest resource is protected and the environmental pollution is reduced.

Description

technical field [0001] The invention relates to a method for planting black fungus in bags, in particular to a bag of black fungus containing pine chips and a preparation method. Background technique [0002] At present, the cultivation of black fungus in my country is gradually transitioning from traditional basswood cultivation to bag material cultivation. Bag material black fungus is cultivated by using miscellaneous sawdust, bran, gypsum and other raw materials, of which miscellaneous wood chips are the main raw materials, generally accounting for 80% of the formula. , Miscellaneous wood is generally dominated by Fagaceae raw materials. With the continuous expansion of bagged black fungus cultivation in recent years, the demand for miscellaneous wood resources is also increasing, which to a certain extent has caused the contradiction between the raw materials needed for black fungus production and the protection of natural forests. The vast number of domestic edible fung...

Problems solved by technology

[0005] The above two invention patents of black fungus did not mention pine sawdust. Pine sawdust contains terpenes and aromatic oils, which have an inhibitory effect on mycelia, and generally cannot be directly used for the cultivation of black fungus.
