To develop the new raw materials for cultivation of Flammulina velutipes and the resource utilization of bamboo debris, the mycelial growth, fruiting body growth and economic benefits of F. velutipes was studied in 9 types of bamboo shavings replacement medium culture formulas (A, B, C, D, E, F, G, H, I) and the cottonseed husk formula cultivated for F. velutipes in local as a control (CK). Results shown that the hyphae of F. velutipes in treatment C, D, E, F and G were the strongest, and in treatment A, B, H and CK were stronger, and in treatment I was weaker. The mycelial growth speed of formula A, B, C, D, E, F, G, H and I were better than that of CK. Average bag yield of fresh mushrooms of formulas G was the highest, 0.33 kg / bag, respectively, with a biological efficiency of more than 80%The average yield of treatment F was the highest, followed by treatment E. According to various indicators, the formula suitable for the growth of F. velutipes was G (64% bamboo debris, 16% cottonseed hull, 8% sawdust, 10% bran, 1% white sugar and 1% plaster).
