Cultivation method of edible fungi rich in organic selenium

The invention relates to a method for cultivating edible mushrooms rich in organic selenium, which comprises the following steps of: selecting a corresponding cultivation medium according to an edible mushroom strain, and inoculating the edible mushroom strain into the cultivation medium for strain cultivation to obtain an initial bacterial suspension; mixing the culture medium with an organic selenium stock solution to prepare a selenium-containing culture medium, and inoculating the sterilized selenium-containing culture medium with an edible fungus strain. When the growth cycle of the strain is prolonged to be more than one time of that of the strain cultured by the selenium-containing culture medium with the previous selenium concentration and the selenium-containing character of the strain is stable, the final organic selenium edible mushroom is obtained. Therefore, the selenium-rich food has relatively high selenium content, and can be matched with the preparation of various health-care foods. The cultu
