The invention relates to a cultivation medium and cultivation method for artificially-cultivated phellinus igniarius and aims to solve the problems that artificial phellinus igniarius cultivation is just started, a small amount of exploring experiments are performed in some regions, and the immature cultivation technology is low in yield, poor in phellinus igniarius quality and low in phellinus igniarius effective component content. The method includes: preparing cultivation medium which comprises, by weight, 56 parts of miscellaneous wood chips, 32 parts of cottonseed hull, 10-13 parts of fresh pig manure, 1 part of sugar and 1 part of quick lime, wherein the mass ratio of the nutrition mentioned above and water is 1:1.2; preparing a phellinus igniarius cultivation bag, sterilizing at high temperature, inoculating activated phellinus igniarius mother strain, cultivating for 20-25 days until the bag is filled with mycelia, cutting an arc-shaped small opening in the middle of the cultivation bag, controlling fruiting temperature at 35 DEG C, keeping the air moist, cultivating for 25-30 days, and harvesting when the fruiting bodies are ripe. Compared with the prior art, the cultivation method has the advantages that the production cycle is short, the fruiting bodies are high in yield, good in quality and high in flavonoid content.
