The decline of greenhouse soil quality restricted the sustainable development of vegetable industry. The influence of different conditioner on the physical and chemical properties and the nutrients environmental effect were studied by experiment. The result showed that the experiment treatments had lower surface soil bulk density and higher field moisture capacity by applying test materials, and soil improvement effect of woody conditioner was better than the humic acid potassium and herb source conditioner. By applying test materials, the contents of soil organic matter were improved, the contents of nitrogen, phosphorus and potassium were also improved, the contents of the total nitrogen were decreased, soil carbon and nitrogen ratio was risen. Using woody source and herb source conditioners would reduce soil nitrogen movement. In addition, using potassium humate and woody source conditioner to cucumber made higher output than other treatments. This study would have some reference value for improving soil properties and soil quality.%设施菜田土壤质量下降制约着蔬菜产业持续发展. 采用不同调理剂对设施土壤理化性状及氮磷环境效应进行试验研究.结果表明,施用试验材料的表层土壤容重均低于对照,田间持水量均高于对照,其中木本调理剂改土作用优于腐植酸钾和草本源调理剂处理;施用试验材料土壤有机质含量有所上升,土壤有效氮磷钾含量均有所提高,全氮含量有所下降,土壤C/N比有所增加;施用木本源和草本源调理剂对减缓土壤氮下移有一定作用. 另外,腐植酸钾和木本源调理剂处理黄瓜产量均显著高于其他处理. 该研究对改善土壤性状与提升设施土壤质量具有一定参考价值.
