In order to provide an optimum cultivation formula for high product of three edible fungi by using Caragana intermedia powder as main cultivation material，which was accounted for 78% (Formula A)，68% (Formula B) and 58%(Formula C) in three different media，some parameters were analyzed for the major characters including time of mycelial growth (d)，time of first primordium appearance (d)，and weight of sporophores per plastic bag，percentage of commercial sporophores on weight basis and biological conversion rate.The results showed that the cultivation of oyster mushroom，mushroom，black fungus，could normal growth and formation of fruiting bodies，while different ratio of substrate had different effect on the agronomic traits and biological efficiency，increased corncob could increase the growth rate，and improve the biological conversion rate.Formula C resulted in the highest biological efficiency of 64.9%，could be used as the high yield formula for cultivation.
