摘　　要：以生物杀线虫剂路富达、淡紫拟青霉、厚垣轮枝菌、苦参碱、植物源杀线虫制剂等为试材,研究了其对日光温室内番茄根结线虫病的防治效果。结果表明,不同水平的生物杀线虫剂对番茄的长势及光合特性均有一定的促进作用,也有较好的增产效果。可以将日光温室内根结线虫病情指数降低20%~30%,产量提高40%~50%。其中施用15.0 kg·hm-2淡紫拟青霉的处理对日光温室内番茄根结线虫防效达到36.27%,相比对照增产36.93%,效果最为明显。The control effect on tomato root-knot nematode disease in solar greenhouse was studied by using the insecticide nematode,Velum,Paecilomyces lilacinus,Verticillium chlamydosporium,Matrine and plant nematode preparation. The results showed that the growth and photosynthetic characteristics of tomato were promoted by different levels of biological nematocides,and the yield increased too. The root knot nematode in greenhouse disease index decreased by 20% ~ 30%,and the yield increased by40% ~ 50%. The application of Paecilomyces lilacinus at 15. 0 kg·hm-2 level on greenhouse tomato root knot nematode control effect reached 36. 27%,and the yield increased by 36. 93% compared with the control,having the most obvious effect.
