从烟草中筛选到几株内生菌进行防治根结线虫的盆栽试验，以研究其防治效果。结果表明，内生细菌发酵液的防治效果优于内生细菌菌体，内生放线菌则相反。内生菌普遍对植物具有促生作用，但内生菌菌体的促生效果优于内生菌的发酵液。H3号内生细菌对根结线虫防治效果最好，病情指数为4．16，防效为91．68％，明显优于对照，优于阿维菌素处理，H3号内生细菌处理的烟草形态指标明显优于阿维菌素处理。

Several tobacco endophyte strains were screened out, and their controlling effect against tobacco root-knot nematodes was studied with pot experiment. The fermentation broth of endophytic bacteria was more effective than the bacterial thallus, while that of endophytic actinomycetes was less effective than the actinomycete fermentation broth. All test endophytes promoted tobacco growth, and the promotion effect of their thalii was better than that of their fermentation broths. Endophytic bacterial strain H3 was the best in controlling tobacco root-knot nematode disease, with 91.68% controlling ...
