Abstract

本发明属于生物技术领域,具体涉及一种用于苜蓿田抗除草剂反枝苋的生防菌剂及其应用。所述生防菌剂包含被孢霉菌株MXBP304的菌丝体和/或孢子悬浮液作为活性成分。所述微生物菌株为MXBP304,被孢霉属(Mortierella sp.)真菌,编号MXBP304,该菌株已于2021年12月22日保藏于湖北省武汉市武昌区八一路299号,保藏编号为CCTCC NO:M 20211660。浓度为2.8×107 CFU/mL的孢子悬浮液可显著抑制反枝苋的种子萌发,相对发芽率27.45%、根长显著下降29.57%。同时,该处理对苜蓿的种子萌发、生长及主要营养品质无不良影响,表现出优异的选择性和促生作用。
