摘要
再生水灌溉利用是解决世界范围内水资源短缺的重要途径。通过查阅国内外相关文献,介绍了使用再生水灌溉对土壤和微生物的影响研究概况。从文献报道情况看,短期使用再生水灌溉对土壤的影响不显著,长期使用再生水灌溉可以增加土壤肥力和微生物种群密度,但会造成盐分(尤其是钠盐)及重金属浓度的累积,导致土壤盐渍化和重金属污染。同样,再生水灌溉对植物也会产生不同的影响。
Reclaimed water for green land irrigation is an important way to solve the shortage of water resources around the world. By reviewing relevant literatures at home and abroad, the general situation of research on the effects of reclaimed water irrigation on soils and microbes were introduced. In general, the effects on soils of short-term use of reclaimed water for soil irrigation is not significant, but long-term use will change soils fertility and microorganisms population density, which lead to accumulation of salt （especially Sodium salt） and heavy metals. Meanwhile, reclaimed water irrigation has no significant effect on plant growth and development, but will increase mineral element content in plants.
