| 摘 要： | 采用大田定位调查的方法,对浇灌中水(灌溉清水为对照)经过7年的草坪绿地理化性状及肥力进行测定分析,结果表明,在长期中水浇灌下,与清水对照相比,中水灌溉使绿地土壤pH降低,孔隙度增大;全氮、全磷含量均有高于清水对照的趋势,且与清水对照之间差异不显著(P＞0.05);碱解氮、有效磷和速效钾含量均高于对照,且差异显著(P＜0...

| Abstract: | The soil physicochemical properties and fertility of greenbelt irrigated with reclaimed water for 7 years were studied.The result indicated that the pH value decreased and porosity increased.The contents of total nitrogen and total phosphorus were higher than control,but there were no significant difference between reclaimed water irrigation and tap water irrigation.The contents of available nitrogen,available phosphorus and available potassium were also higher than control and the difference was significan... |
