摘　　要：以棉籽壳为主料,以杏鲍菇为研究对象,采用袋栽方法,测定了杏鲍菇在不同栽培阶段木质纤维素的降解、呼吸消耗和绝对生物学效率。结果表明:杏鲍菇降解纤维素和半纤维素的能力较弱,降解木质素的能力较强;非木质纤维素主要在杏鲍菇菌丝生长阶段被利用,木质纤维素是子实体生长发育阶段的主要碳源;在70d的栽培过程中,杏鲍菇培养基失重30.65%,呼吸消耗22.67%,绝对生物学效率(子实体生物量)7.98%;杏鲍菇菌渣中纤维素和半纤维素含量比棉籽壳高,具有重新利用价值。With cotlonseed shell as major medium,taking Pleurotus eryngii as research object,lignocelluloses degradation, respiration consumption and absolute biological efficiency were determined at different stages of development from Pleurotus eryngii cultivated on the cottonseed shell medium in bag. The results showed that P. eryngii degraded cellulose and hemieelluloses weekly and lignin strongly,so it belonged to white-rot fungi. Nonlignocellulose was principally used at the stage of mycelia growth. However,tignocelluloses were the main carbon source for the fruiting stage of the fungus. At the end of cultivation （70 d）, the medium reduction （dry weight） was 30. 65 %, the respiration consumption was 22.67%, and the absolute biological efficiency （biomass of fruit bodies） was 7.98%. The content of cellulose and hemicellulose in residue of P. eryngii was higher than cottonseed shells,so it has reuse value.
