Edible fungus cultivation base material as well as preparation method and application thereof

The invention discloses an edible fungus cultivation base material and a preparation method and application thereof, and belongs to the technical field of edible fungus cultivation. The edible fungus cultivation base material is prepared by compounding flammulina velutipes residues, mushroom residues, tremella residues, ammoniated straw powder, brown algae powder, sugar alcohol, sawdust, corn flour and gypsum. The three mushroom dregs and ammoniated straw powder are compounded, so that the nitrogen content of the cultivation base material is increased, carbon-nitrogen balance in the cultivation base material is maintained, brown algae powder and sugar alcohol are matched, the activity of shiitake mushroom strains is improved, spawn running hyphae are more uniform, the fruiting quality is more balanced, sugar alcohol is used for replacing a traditional sucrose component, and the cost is reduced. The heat in the shiitake mushrooms is further reduced, and the shiitake mushrooms are endowed with a better taste. O
