Provided is a method for increasing the content of vitamin D 2 in mushrooms. The method comprises the following steps: exposing cell membranes of mushrooms containing ergosterol to ultraviolet rays, and performing ultraviolet irradiation treatment on the mushrooms. The process of exposing cell membranes of mushrooms containing ergosterol to ultraviolet rays comprises: (1) performing pulverization and wall breaking on mushrooms containing ergosterol to obtain a powder material; and (2) placing the powder material obtained in step (1) in an environment surrounded by ultraviolet rays in a fluidized and suspended state. A method for preparing edible mushroom powder comprises: treating mushrooms containing ergosterol by means of the method for increasing the content of vitamin D 2 in mushrooms, and then drying to obtain the edible mushroom powder.
