Description
Summary:Bamboo debris are rich in nutrients and suitable for the cultivation of edible fungi. In order to develop the new raw materials for cultivation of Pleurotus geesteranus and the resource utilization of bamboo debris, the mycelial growth, fruiting body growth and economic benefits of P. geesteranus was studied in 9 types of bamboo debris replacement medium formulas (A, B, C, D, E, F, G, H, I) and the cottonseed husk formula cultivated for P. geesteranus in Leshan City as a control (CK). Results shown that formula G was suitable for the growth of P. geesteranus. The composition of the formula G was 64% bamboo debris, 16% cottonseed husk, 8% sawdust, 10% bran, 1% white sugar and 1% plaster. In formula G, the average growth rate of P. geesteranus mycelia was 5.39 mm / d, 7.67 mm / d, and 8.42 mm / d in 10 days, 15 days, and 20 days after inoculation, average bag yield was 0.33 kg / bag, biological efficiency was 89.87%, and the ratio of output value to input value was 3.34.
