The invention discloses a method for culturing pleurotus pulmonarius by means of linen combings. The method includes the steps of: 1) preparation of a culture medium: under natural pH value, weighing the raw materials including, by weight, 40-60% of the linen combings, 10-20% of corncob, 10-20% of wood chips, 15-20% of wheat or rice bran, 1% of gypsum powder and 1% of lime, and crushing the linen combings into granules being 0.5 +/- 0.1 cm in size, completely wetting the linen combings, uniformly mixing the linen combings with the wood chips, wheat bran, lime and gypsum powder, adding water until water content is 60%, and packaging the mixture in bags and sterilizing the mixture to obtain the culture medium; 2) inoculation; 3) spore germination; 4) cultivation and management during fruiting; 5) harvesting. In the method, the pleurotus pulmonarius is cultured with the linen combings, thus turning wastes into resources. The method not only reduces production cost of the pleurotus pulmonarius and shortens culture period thereof, but also can produce the pleurotus pulmonarius with high yield, good quality and abundant nutrients. The pleurotus pulmonarius has healthcare functions and medicinal value.
