NOVELTY - Method for cultivating Ganoderma lucidum, involves immersing granules of shiitake mushroom residue in purified water, mixing immersed mixture with sugarcane bagasse granules, adding bean cake, covering mixture with grass, fermenting and cooling the mixture to obtain matrix, inoculating the G.lucidum into the matrix, spraying lixivium on the matrix, and cultivating and harvesting the G.lucidum, where lime is added to the mixture and the mixture is turned once/day during fermentation.    USE - The method is useful for cultivating G.lucidum.    ADVANTAGE - The method improves bioconversion rate of G.lucidum, saves labor, and is environmentally-friendly.    DETAILED DESCRIPTION - Method for cultivating Ganoderma lucidum, involves (a) obtaining 70-74 %mass sugarcane bagasse, 18-22 %mass bean cake, 3-4 %mass shiitake mushroom residue, 3-4 %mass lime and 1 %mass gypsum, drying the sugarcane bagasse, crushing the sugarcane bagasse to obtain granules, and drying and crushing the shiitake mushroom residue to obtain granules, (b) adding 20-30 times purified water to granules of shiitake mushroom residue for immersing the granules of shiitake mushroom residue in purified water for 18-24 hours, mixing immersed mixture with sugarcane bagasse granules, adding the bean cake to obtained mixture, covering the mixture with grass, fermenting the mixture at 60 degrees C for 5-6 days, maintaining moisture content of fermented product at 63-65%, and cooling the fermented product to obtain matrix, where lime is added to the mixture and the mixture is turned once/day during fermentation, and then gypsum is added to the mixture and turning the mixture is turned for 3-4 times during fermentation, and (c) inoculating the G.lucidum into the matrix, spraying 0.015 g/ml lixivium on the matrix, and cultivating and harvesting the G.lucidum, where 3-4 kg lixivium is sprayed per square meter of matrix. The lixivium is prepared by adding 20 times purified water to shiitake mushroom residue for immersing the shiitake mushroom residue for 18-24 hours, removing filter residue, and diluting obtained product using purified water.
