摘　　要：污水处理过程中会产生大量的污泥,污泥的处置已成为人们日益关注的问题。污泥在绿地植物上的应用是实现污泥资源化的有效途径。为此,本文对污泥对绿地植物生长和生理方面影响的研究进行了总结,认为污泥对绿地植物的生长品质、生物量的增加和开花具有促进作用;对其矿质元素的积累、渗透调节、激素和酶的代谢、叶绿素和抗性的增加有良好效果;同时污泥对绿地植物发芽和幼苗生长有抑制作用,过量还能对绿地植物的生长产生毒害且有引起土壤重金属污染的风险。The sewage treatment process produced large amounts of sludge whose disposal has become a growing concern. The most effective utilization is applied on green plant. The up-to-data research about the effects of sludge on green plants growth and physiology were summa：ized in this review. Most of the research showed that sludge not only improved the quality, biomass and flowering of green plants, but also induced the accumulation of mineral elements, osmotic adjustment, hormones and enzymes metabolism, chlorophyll content and resistance enhancement. However, sludge constrain germination and seedling growth of green plants and the excess sludge poisoned green plants and caused heavy metal pollution of soil.
