摘　　要：为克服设施农业种植过程中的连作障碍,减少土壤中的根结线虫数量,提高作物产量和质量。本文设计了一种微波土壤处理设备,该设备将产生的微波直接辐射于连作后的土壤进行现场作业,实现了微波就地土壤处理。通过田间试验表明,微波处理过土壤中的根结线虫数量比未经微波处理过土壤中的根结线虫数量明显减少,与土层深度150mm和200mm相比,在土层100mm时,微波杀菌效果最明显;其中,处理90s对中间和右侧土层深度100mm土壤中的根结线虫效果最佳,土壤中的根结线虫降低了82.3%,结果为微波处理直接应用于设施农业土壤杀菌提供了参考依据。In order to overcome continuous cropping obstacles in the process of planting,reduce soil of the root nematode quantity,and improve quantity and quality of products.This text designed a kind of microwave soil treatment equipment.The machine could put microwave into the soil of continuous cropping,realizing the microwave treat soil on-site.A field experiment was conducted to show that microwave treatment could reduce root-knot nematodes population in soil.The result was obvious in 100mm soil compare with 150mm and 200mm soil depth.The optimal disinfection condition was 90s of microwave treatment,the number of root nematode deceased by 82.3% in 100mm soil depth,which provided references for the microwave treatment soil.
