摘  要：
采用袋栽研究了杏鲍菇、白灵菇对芦笋老茎中木质纤维素的分解利用情况,结果表明,在菌丝生长阶段,杏鲍菇、白灵菇对木质纤维素的降解量分别为18.08,17.39 g,分别占培养料失质量的74.43%,76.01%;在子实体发育阶段,杏鲍菇对木质纤维素的降解量占培养料失质量的80.15%～94.03%,白灵菇对木质纤维素的降解量占培养料失质量的70.49%～94.56%;在整个栽培过程中,杏鲍菇、白灵菇对培养料木质纤维素的降解量分别为105.79,104.50 g,分别占培养料失质量的83.22%,80.51%。这说明杏鲍菇、白灵菇生长发育所需要的83.22%,80.51%的碳源来自于木质纤维素。杏鲍菇、白灵菇对芦笋老茎培养料中木质素的分解率分别为81.31%,80.38%,对纤维素的分解率分别为72.20%,69.03%,对半纤维素的分解率分别为56.14%,59.72%,说明杏鲍菇分解利用芦笋老茎中木质纤维素的能力强于白灵菇。在试验条件下,杏鲍菇的发菌时间、出菇时间均比白灵菇短,出菇产量和绝对生物学效率也较白灵菇高,这从另一个角度证明了杏鲍菇具有比白灵菇更强的分解利用芦笋老茎中木质纤维素的能力。

摘  要：
Using bag cultivation,a study on the decomposition lignocellulose in old stem of asparagus by Pleurotus eryngii and Pleurotus nebrodensis was carried out.The result showed: at their mycelial growth stage,the degradation amounts of lignocellulose by Pleurotus eryngii and Pleurotus nebrodensis were 18.08 g and 17.39 g respectively,which accounted for 74.43% and 76.01% of substrate weightlessness;at the developmental stage of fruiting bodies,the degradation of lignocellulose by Pleurotus eryngii accounted for 80.15% ～94.03% of substrate weightlessness,the degradation of lignocellulose by Pleurotus nebrodensis accounted for 70.49% ～94.56 % of substrate weightlessness;in the whole process of cultivation,the degradation amounts of lignocellulose by two mushrooms reached 105.79 g and 104.50 g respectively,which accounted for 83.22% and 80.51% of substrate weightlessness.This result showed that the 83.22% and 80.51% of carbon sources needed respectively by the growth and development of Pleurotus eryngii and Pleurotus nebrodensis originated from lignocellulose in substrate.The chemical analyses results showed that the lignin decomposition rates of Pleurotus eryngii and Pleurotus nebrodensis were 81.31% and 80.38%,the cellulose decomposition rates were 72.20% and 69.03%,and the hemicellulose decomposition rates were 56.14% and 59.72%,which indicated that the decomposition ability of Pleurotus eryngii in old stem of asparagus was stronger than that of Pleurotus nebrodensis.In this experiment,it was also found that the spawn running time and fruiting bodies production time of Pleurotus eryngii were shorter than that of Pleurotus nebrodensis,and the mushroom yield and biological efficiency of the former were relatively higher than that of the latter.It was another proof that Pleurotus eryngii was stronger than Pleurotus nebrodensis in lignocellulose decomposition ability.
