近几年,我国北方保护地蔬菜根结线虫病呈明显加重趋势,已成为保护地蔬菜生产的严重障碍〔1〕。目前防治根结线虫病主要采取杀线剂进行土壤处理。由于蔬菜上可用的杀线剂品种少、成本高,防治效果易受土壤环境、施用方法、生产者投资心理等影响,难以获得较理想的持续综合控制效果 In recent years, the root-knot nematode disease in northern protected areas of our country is obviously aggravating, which has become a serious obstacle to the production of vegetables in protected areas [1]. At present, root knot nematode prevention and treatment mainly take nematicide soil treatment. As there are few varieties and high costs of the nematicide available on vegetables, the control effect is easily affected by the soil environment, the application method and the investment psychology of the producers, so that it is difficult to obtain the ideal continuous comprehensive control effect
