摘　　要：研究羽叶决明(Chamaecrasta nictitans)代木栽培鸡腿菇(Coprinus ovatus)对其绝对生物学效率、基物失重、呼吸消耗及木质纤维素转化的影响。结果表明,羽叶决明牧草替代60%木屑(A60)栽培鸡腿菇的绝对生物学效率最高,均为10.77%。覆土前和采收后的基物失重和呼吸消耗都以A0(CK)为最高,分别为11.47%、11.47%和31.75%、25.55%,其木质素转化率也最高,为79.21%;纤维素转化率以A100(羽叶决明牧草替代100%木屑)为最高,达50.93%;半纤维素转化率以A40(羽叶决明牧草替代40%木屑)为最高,为49.74%。回归分析结果表明,绝对生物学效率和半纤维素转化率与替代比例呈抛物线相关,而基物失重、呼吸消耗及木质素、纤维素转化率与替代比例呈线性相关。Mushroom Coprinus ovatus was cultivated on a series of growth substrates in which the sawdust component was substituted with Chamaecrasta nictitans to study C. nictitans in terms of biological efficiency, substrate weight loss, respiration-based consumption and conversion of xylem cellulose. The treatment A60（C. nictitans replacing 60% of the sawdust） had the highest absolute biological efficiency （10.77%）. Treatment A0（0% C. nictitans replacing the sawdust, CK） or the control had the highest substrate weight loss and respiration-based consumption either before soil covering or after harvest, which were 11.47% and 11.47%, and 31.75% and 25.55%, respectively, and the lignin conversion rate in the treatment A0 was highest（79.21%）; the cellulose conversion rate in the treatment A100（100% C. nictitans substituting the sawdust） was the highest（50.93%）; and the semi-cellulose conversion rate in the treatment A40 （40% C. nictitans substituting the sawdust） was the highest（49.74%） among all the treatments. Regression analysis revealed that the absolute biological efficiency and semi-cellulose conversion had significant parabolic correlation with the percentage of substitution of sawdust with C. nictitans, and that the substrate loss, respiration-based consumption, lignin conversion and cellulose conversion were linearly correlated with the percentage of substitution of saw dust with C. nictitans.
