摘　　要：通过分别向马铃薯葡萄糖培养基(PDA)和木屑栽培基质中加入不同含量的竹笋壳提取液和竹笋壳,探讨对平菇的菌丝生长和产量的影响.结果表明:PDA中不同含量的竹笋壳提取液均能提高菌丝的生长发育,其中含有60g/L浓度的竹笋壳提取液对菌丝的生长速率促进作用最大;添加竹笋壳的栽培基质能有效提高平菇产量和对栽培料的生物转化率,增加效果最好的竹笋壳添加百分浓度均为80%,分别比对照组提高828g的产量和82.8%的生物转化率.Pleurotus ostreatus was cultivated in Potato Dextrose Agar Medium（PDA） and sawdust growth substrates, which include different concentration of bamboo shoot shell extract and bamboo shoot shell respectively. The result shows that all concentrations of the bamboo shoot shell extract in PDA can increase hypha growth of Pleurotus ostreatus, the best concentration of increasing Mycelial growth rate is 60g/L. The sawdust growth substrates with bamboo shoot shell can increase the yield of Pleurotus ostreatus and the biological efficiency in medium. The best concentration bamboo shoot shell is 80%, which can raise 828g of the yield and 82.8% of the biological efficiency.
