Edible fungus cultivation technology using bean dreg liquid

The invention provides a method for liquidly culturing edible fungus mycelia using soybean residue as main material. The different edible fungus mycelia are liquidly cultured by adding different ratio of sucrose or glucose, different ratio of magnesium salt, phosphate, calcium salt and ferric salt into the main materials of soybean residue immersion liquid and soybean residue. The method is suitable for liquidly culturing most edible funguses and has advantages of big density of mycelial pellet, easy separation, high biological conversion rate, low material cost, simple technology, easy industrialization. The produced edible fungus mycelia can be used in producing healthy food and drug such as edible healthy soybean powder, edible fungus polysaccharide preparation, edible healthy drink and the like.
