摘　　要：土壤消毒是防治土传病虫害的有效手段。对土壤进行田间微波处理,然后取不同深度的土样进行室内培养,来观察微波消毒对土壤中病原微生物的防治效果。结果表明:微波消毒对土壤中的微生物都有杀灭作用,其中微波发生器处理10 min对土层深度5 cm土壤中的细菌和线虫杀灭效果最佳,杀灭率分别是74.48%和70.73%;微波处理10 min对土层深度10 cm土壤中的真菌和放线菌杀灭效果最佳,杀灭率分别是85.65%和83.25%。Soil sterilization is an effective method in soil pest control.In this study microwave was utilized for field soil treatment,and then soil was collected in different depth for indoor incubation in order to observe the control effect of microwave sterilization on soil microbial groups.The results showed that microwave sterilization could reduce microbial population in soil.The optimal disinfection condition was 10 min of microwave treatment,resulting in sterilizing rate of 74.48% and 70.73% on bacteria and nematode in 5cm soil depth,and of 85.65% and 83.25% on fungi and actinomycetes in 10cm soil depth,respectively.
