The invention relates to a black fungus cultivation method. The method includes following steps: (1), seed preparing, namely, in the middle of January, producing bacteria according to a conventional black fungus planting method, and selecting good bacterium strains to extract fungus mycelium; (2), bacterium stick preparing, namely, preparing bacterium sticks according to a conventional method, and uniformly mixing smashed straw materials of like saw dust, wheat bran, cotton seed hulls and wheat straw to prepare a cultivation material; (3), fungus cultivating, namely, inoculating sterilized fungus sticks according to sterile operating instructions, cultivating mycelium, and maintaining a normal-temperature, dark and dry indoor environment during the fungus cultivating period which is about three mouths; (4), fungus placing, namely, directly placing the fungus sticks after fungus cultivating outdoors; and (5), recovering. The cultivation material used in the cultivation method greatly lowers proportion of saw dust in the cultivation material, so that environment protection is realized; no chemical product with toxin is added, so that more health is realized; waste skin and hulls of various other agricultural products are added, so that cost is lowered; and an optimum proportion is obtained through experiments, so that growing speed of black fungus is evidently increased, and mineral content, protein content and content of various vitamins in black fungus products are increased, so that nutrient is enriched.
