- 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。
- Abstract:
- 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.
