The invention discloses an antrodia cultivating method.The method comprises the steps of strain culture medium manufacturing, strain isolation and expanding propagation, carrier cultivating, inoculation, mycelial growth and sporocarp growth.The antrodia cultivating method has the advantages that due to the cultivating method is simple and capable of achieving industrialization and standardized production, so that expanded production is promoted, the production cost is lowered, and the cultivating time is short.Low-density wood is adopted as a bacteria bed, mycelial growth is promoted, hyphae can easily form sporocarp, and meanwhile strains can better adapt to bacteria bed growth by improving the strains, so that the fruiting rate can be improved by about 80%, and economic benefits can be improved.The obtained antrodia sporocarp and wild antrodia sporocarp DNA detection equal rate can reach 99%, and the effect is good.The cultivating method can enable the content of triterpene of the antrodia sporocarp can reach 8.6%, the content of polysaccharide can reach 4.8%, and the content of effective elements can be improved.
