| 摘 要： | 自2002年以来,从辽宁本溪、辽阳、葫芦岛、鞍山等地采集的土样中分离得到放线菌菌株252株.采用孢子萌发抑制法、小麦离体叶病害发酵液抑制法筛选出C-2、C-3、C-4 3株放线菌,对小麦白粉痛表现出较强的抑制能力.利用这3株菌株的发酵液进行了小麦白粉病田间防治试验.结果表明,C-2、C-3、C-4 3株菌株的发酵液对病菌孢子萌发的抑制率均在75%以上:对小麦离体叶病害的治疗作用分别为84.36%、65.1%和67.91%;田间小区试验的防治效果分别为79131%、56.9%和62.07%.

| Abstract: | In this study, a total of 78 soil samples for sieving pathogen-inhibiting actinomycetes isolates were collected from towns or counties such as Benxi,Liaoyang,Huloudao,Anshan etc. in Liaoning Province since 2002, 252 isolates of actinomycetes were obtained, and 3 promising isolates, nameed, C-2, C-3, C-4, were singled out according to their ability of inhibiting oidium spore germination of powdery mildew of wheat and of controlling disease on detached primary leaves. The further study indicated that the ferm... |
