Abstract

The invention aims to provide a method for preparing an earthing material for cultivating edible fungi. The method comprises the following steps of: sun-drying or drying fungus chaff of the edible fungi, crushing and sieving; adding water, and adjusting the moisture content of fungus chaff powder of the edible fungi, and putting the fungus chaff powder into an extrusion bulking machine for extruding and bulking; crushing the bulked fungus chaff powder of the edible fungi; and adding a certain amount of pulverized coal, gypsum powder and / or lime powder, and stirring uniformly to obtain the earthing material for cultivating the edible fungi. The method is easy to operate; and compared with the common turfy soil, the prepared earthing material for cultivating the edible fungi is cheaper, but does not influence the quality and yield of sporophores of the edible fungi.

Description

Technical field: [0001] The invention provides a method for making a soil-covering material for edible fungus cultivation, which belongs to the technical field of edible fungus cultivation. Background technique: [0002] Edible fungus chaff, also known as mushroom dregs, mushroom dregs and fungus dregs, etc., is a solid culture that is discarded after the production of edible fungi, with cottonseed hulls, sawdust, straw, corncobs or various crop straws, and industrial waste as the main raw materials. The base, often discarded after the fungi are harvested, is the main waste generated by the mushroom industry. After these culture materials are enzymatically hydrolyzed by various enzymes secreted by the mycelium of edible fungi, macromolecular substances such as cellulose, hemicellulose, lignin, and protein have been degraded and utilized to varying degrees. The content of crude protein and crude fat is increased; and it is rich in amino acids, polysaccharides, calcium, phosp...
