摘　　要：[目的]探讨叶芥苗期根肿病综合防治技术,为叶芥的安全生产提供参考。[方法]通过田间试验从翻耕、播期、药剂处理3个方面研究了叶芥苗期根肿病综合防治技术。[结果]土地翻耕、调节播期、苗床消毒处理方式都影响根肿病在叶用芥菜苗期的发生程度;翻耕炕土、延迟播期、苗床消毒能适度降低叶芥苗期根肿病的发病率和发病指数,相对防效最高可达97.2%。[结论]试验结果为叶芥根肿病的防治提供了理论依据。[ Objective ] Integrated control of clubroot of leaf mustard （ Brassica juncea L. ） at seedling stage was explored to provide reference for safe production of leaf mustard. [ Method ] Integrated control technology of clubroot in leaf mustard （Brassica juncea L. ） at seedling stage was gudied through experiment in field. [ Result] All the factors like soil moisture, seeding time, sterile method of nursery had effect on incidence of clubroot. Ploughing and airing the soil, delaying seeding and nursery sterilization could reduce＇incidence and disease index of clubroot disease. [ Conclusion] The results provide rheoretical basis for the control of clubroot of leaf mustard.
