The invention discloses a method for cultivating mushroom containing calcium, which comprises: a step of material mixing, in which components in weight percentage, including 70 to 80 percent of wood flour, 10 to 20 percent of wheat bran, 5 to 10 percent of corn flour, 1 to 10 percent of plaster and 4 to 10 percent of crab powder, are mixed, stirred and added with water the weight of which is 58 to 60 percent of total weight of the components, and the mixture is stirred uniformly; a step of bagging: the mixture obtained is filled into edible fungus bags; a step of sterilization; a step of inoculation; and a step of mushroom emergence. Due to the crab powder added in the mixture, the produced mushrooms have high calcium content and contain additive nutrients which are good for the human bodies and can be absorbed completely by human bodies. The edible mushrooms cultivated by the method can maintain and adjust a plurality of physiological and biochemical processes in organisms, adjust releasing of transmitter, increase the secretion of endocrine glands, keep the integrity and permeability of cell membranes, promote the regeneration of cells and increase the immunity of the organisms.
