| 摘 要： | 经病苗组织分离培养确定,杉苗猝倒病的病原菌,Rhizoctonia solani占59.7％、Fusarium spp.占38.9％、Pythium spp.占1.4％。在室内通过Trichoderma harzianum(Fo60)对敌克松(Dexon)耐药性测定表明,Fo60对敌克松有极大耐性;经田间小区试验表明,同对照相比,每平方米施敌克松4克三天后再施Fo60菌粉50克,只施菌粉50克和只施敌克松4克处理,三种病原菌引起的杉苗猝倒病分别减少71.1％、53.4％、43.8％;由R.solani导致的杉苗猝倒病分别减少99.5％、92.2％和43.8％。其中均以敌克松同Fo60菌粉联合防治最好。

| Abstract: | The damping-off of Cunninghamia lanceolata was caused by Rhizoctonia solani, Fusarium spp.and Pythium spp. An isolate (Fo60) of Trichoderma harzianum cultured from wheat bran-vermiculite was tolorant to Dexon and antagonistic to R.solani in PDA plates.In field plot experiments this isolate was effective for control of the damping-off of Cunninghamia lanceolata, but the combination of FO60 and Dexon was the most effective. |
