However, when straw is crushed, the water content of the straw is required to be low, and fresh straw with high water content cannot be crushed. The crushing will not sufficiently damage the dense physical structure of the straw, and the specific surface area of the straw will not increase significantly, which is not conducive to the decomposition and utilization of edible fungi. low efficiency

Abstract
The invention relates to a method for cultivating edible fungi through straw filament kneading treatment. Straw selected for preparing cultivated species and composite used during cultivation is filament-kneaded wheat straw or filament-kneaded corn straw. The method specifically includes the steps that 1, a PDA culture medium flat plate is inoculated with edible fungus mycelium blocks, the edible fungus mycelium blocks are cultured till the flat plate is full of mycelia, and mother species is obtained; 2, test tubes are filled with the composite, each tube is filled with 200 g of the composite, sterilization is carried out for 1-2 h at the temperature of 120-125 DEG C, then the test tubes are inoculated with the mother species obtained in the step 1, the materials are cultured till the tubes are full of the mycelia, and the culture species is obtained; 3, the composite is bagged, each bag is filled with 500 g of the composite, sterilization is carried out for 1-2 h at the temperature of 120-125 DEG C, then the bags are inoculated with the culture species obtained in the step 2, and conventional management fruiting and harvesting are carried out. By means of the method, the mycelium growth speed and the yield of first two tides of mushrooms can be remarkably increased.
Description
technical field [0001] The invention belongs to the technical field of edible fungus cultivation, and in particular relates to a method for cultivating edible fungi by shredding straw. Background technique [0002] Crop straw is the most abundant renewable resource in the world. According to statistics, the world's annual straw output is about 2.9 billion tons, and my country's straw output has exceeded 1 billion tons. Straw cultivation of edible fungi can produce edible fungi such as Pleurotus ostreatus, Shitake mushroom, Straw mushroom, Coprinus comatus, Auricularia bisporus and mushroom chaff, which not only makes full use of crop straw, but also increases economic benefits, making farmers rich good way. [0003] Traditional edible fungus cultivation uses straws that are often crushed to shorten the straw and reduce the particle size, which is convenient for mixing, bagging and growth and utilization of edible fungi. However, when straw is crushed, the water content of...
