摘　　要：[目的]探讨生防菌BC2007对番茄的促生防病作用。[方法]对重组的基因工程菌BC2007的GFP基因以及苯酚羟化酶基因进行了检测,并通过盆栽试验比较了BC2001和BC2007对番茄的促生防病作用。[结果]生防菌BC2007能减少番茄根系线虫瘤并对番茄的营养生长具有促进作用,也有利于后期产量的形成。[结论]为生物杀线虫菌剂的研制提了供理论依据。[ Objective ] The aim was to explore growth-promotion and disease-control effects of biocontrol strain BC2007 to tomato. [ Method ] The GFP gene from recombinant genetic engineering bacteria BC2007 and the phenol hydroxylase gene were determined. Growth-promotion and disease-control effects of biocontrol strain BC2001 and BC2007 to tomato were compared by pot experiment. [ Result ] Biocontrol strain BC2007 not only reduced root-knot nematode but also promoted the growth of tomato, furthermore it could enhance the yield of tomato marked- ly. [ Conclusion ] The research provides theoretical basis for the preparation of biological nematicidal inocula.
