Circulating production process method for edible mushrooms

The invention relates to the technical field of circulating production of edible mushrooms, and in particular to a circulating production process method for the edible mushrooms. The circulating production process method for the edible mushrooms comprises the following steps: (1) preparing a culture medium for the edible mushrooms; (2) filling a polypropylene material bag with the culture medium for sterilizing, and inoculating after the edible mushrooms are cooled; (3) preparing liquid strains, inoculating the strains to the culture medium in a purified room, and culturing the inoculated bacterial bag on a culture frame in a culture room; (4) harvesting fruiting edible mushrooms; (5) collecting and crushing the harvested mushroom stems and enabling the crushed mushroom stems to enter a biogas tank to produce biogas; (6) adding part new material into biogas residues produced after the fermenting of the biogas tank, preparing into edible mushroom dreg again, and recycling and utilizingin such a manner, so that
