| 摘 要： | 还田玉米秸秆降解过程中施加含有植物内生真菌的复合菌剂,在盆栽条件下研究了该菌剂对还田秸秆的降解作用,对土壤生态以及后季作物小麦生长的影响。结果表明:添加复合菌剂能够促进玉米秸秆的降解,在前30 d时效果最显著,尤其是木质素的降解,两种复合菌剂处理组木质素降解率分别比市购秸秆腐熟剂高117.36%和242.70%;施用菌剂会显著增加小麦生长早期土壤蔗糖酶、脲酶和纤维素酶的活性,增加小麦生长早期土壤微生物数量;改善土壤理化性质,提高小麦成熟后土壤中的全氮、全钾、碱解氮和速效钾的含量;显著改善小麦生长状况,小麦返青拔节期叶片叶绿素含量显著增加,收获小麦单株生物量和单株产量也有所增加。
