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。
Facilities Vegetable fields The soil environment is an important factor for the efficient production of vegetables. Through the regulation of soil nutrients and control of soil-borne diseases, the environmental conditions in the soil of the facility were adjusted, and the effects of different treatments such as boring + control agent + traditional fertilization, boring shed + regulator + optimized fertilization on the control of soil root- The impact of migration. The results showed that the control rate of boriculture + regulator + traditional fertilization was 79.07%, boring + regulator + optimal fertilization was 86.05%. Optimized fertilization can reduce the nitrogen and phosphorus nutrients to the lower soil migration, thereby reducing the risk of environmental risks. This study has important reference value for controlling root-knot nematode, increasing fertilizer utilization and reducing the risk of fertilization environment.
