摘　　要：对种植油麦菜、大白菜、普通白菜、叶用莴苣及菠菜5种诱集植物前、后土壤中根结线虫的数量变化进行了研究,结果表明:种植诱集植物明显减少了土壤中根结线虫的数量,其中油麦菜对10～30cm土层中根结线虫的控制效果最好,校正虫口减退率达60%以上。对5种诱集植物的根结线虫病情调查表明,5种诱集植物的发病率均达到100%,油麦菜、叶用莴苣、普通白菜、大白菜及菠菜病情指数分别为50.0、29.6、28.4、33.3及25.6。Before and after planting 5 trap crops,the population of root-knot nematodes in soil was studied.The results showed that trap crops have obviously reduced the population of root-knot nematodes in soil.Leaf lettuce has highest efficiency.The insect slipping rate is above 60%,respectively.The result of investigation on population of root-knot nematodes of these 5 trap crops showed that the disease occurrence rates were 100%,and the disease index of leaf lettuce,lettuce,rape,Chinese cabbage and spinach were 50.0,29.6,28.4,33.3 and 25.6,respectively.
