Abstract: This study used Zizyphus jujube crushing material as test materials to select Flammulina velutipes strains,which is appropriate to decompose Z. jujube branches, and select a culture medium formula, which uses Z. jujube branches chip as main substrate. The results showed that “jinza 19” was the F. velutipes strain which was appropriate to decompose Z. jujube branches.The optial cultivation medium was P2.The mass fraction of each component was Z. jujuba branches crumbs 70%, cottonseed hull 10%, bran 18%, lime 2%.On this culture medium,the mycelium growth of F. velutipes is 4.68 mm/d, the biology efficiency is 103.91%, the output-to-input ratio is 1∶8.58.A resource development and utilization model of macrofungi degradation forestry using abandoned-Z. jujuba branches crumbs is thus developed.
