| 摘 要： | 通过盆栽模拟试验,研究短期中水灌溉对绿地土壤理化性质的影响.结果表明:中水灌溉可引起土壤物理指标不同程度的增减变化,其中土壤pH值呈降低趋势,土壤全盐和有机质含量均明显提高,土壤容重、土壤孔隙度和田间持水量与具体植物的种类有关;中水灌溉后绿地土壤养分含量与具体的植物种类有关,各处理与清水对照之间差异显著(P<0.05);同时,中水水质中少量重金属在土壤中有积累的现象,但与清水对照相比差异不显著(P>0.05). |

| Abstract: | Variation of greenbelt soil physicochemical properties under short-term reclaimed water irrigation were studied by potted simulation test.The results showed that using reclaimed water irrigation,soil physical indicators changed differently,which were related to different greenbelt plants.Organic matter and salt content of soil were obviously increased after reclaimed water irrigation,and were significantly different with that of control(P<0.05).Meanwhile,a little of heavy metals in reclaimed water accumulated in soil,but was not significantly different with that of control(P>0.05). |
| Keywords: | reclaimed water irrigation soil physicochemical properties soil salt heavy metal |
