摘　　要：设施菜田土壤环境状况是蔬菜高效生产重要因素。通过养分调控与土传病害综合控制方法调节设施土壤内部环境条件,研究了闷棚+调控剂+传统施肥、闷棚+调控剂+优化施肥等不同综合处理对设施土壤根结线虫控制、土壤养分运移方面的影响。结果表明:闷棚+调控剂+传统施肥的线虫控制率为79.07%,闷棚+调控剂+优化施肥为86.05%。优化施肥能够减少氮磷养分向土壤中下部运移,从而减少环境风险危害。该研究在根结线虫控制、提高肥料利用和降低施肥环境风险方面具有重要参考价值。The soil environment conditions are important factors in high effective greenhouse vegetable product. By nutrients control and soil borne disease control, the influences of different regulation treatments, i. e. ＇stuffy studio-Control Agents-traditional fertilization＇ and ＇stuffy studio-Control Agents-optimal fertilization＇, on root-knot nematode control and soil nutrient movement were studied. The results showed that the root-knot nematode control rate of treatment based on ＇stuffy studio-Control Agents-traditional fertilization＇ was 79. 07%,the control rate of treatment based on ＇stuffy studio- Control Agents-optimum fertilization＇ was 86. 05%. In addition, optimized fertilization could reduce soil nutrient to transfer towards deeper soil layer and decrease environmental disks. It would have important references for controlling soil root-knot nematode ,improving fertilizer use efficiency and reducing environmental risks in greenhouse.
