摘　　要：测定了黄伞(Pholiota adiposa)在棉籽壳-麦麸栽培基质上生长期间培养基失重、呼吸消耗、绝对生物学效率和木质纤维素的降解,结果表明:在94d的栽培过程中,黄伞培养基失重为(52.3±2.1)%,呼吸消耗为(42.7±0.5)%,绝对生物学效率(子实体生物量)为(9.6±0.5)%。黄伞降解纤维素和半纤维素的能力很强,降解木质素的能力很弱。非木质纤维素主要在黄伞菌丝生长和菌丝后熟阶段被利用,纤维素和半纤维素在子实体生长发育阶段消耗很大。Total substrate weight losses, cellulose, hemicellulose and lignin utilization, respiration consumption and absolute biological efficiency values （fruit body dry weight divided by substrate mass）were determined at different stages during the cultivation of Pholiota adiposa.Over a 94 days cultivation period, the percentage substrate weight loss ratio （weight loss divided by original substrate mass）was （52.3±2.1）%, made up of （42.7±0.5）% respiration consumption and （9.6±0.5）% fruit body yield （first and second flush）.Lignocellulose components were largely consumed during the development of the first flush of fruit bodies,while non-lignocellulose material was principally utilized during the spawn running phase.
