中水灌溉对绿地植物影响的研究

污水再利用是解决现代城市缺水问题的最有效途径之一。综述了近年来国内外中水（再生水）灌溉对绿地植物影响的研究成果，即中水灌溉对绿地植物生长有正负两方面的影响，与中水水质、灌溉方式、植物种类、土壤类型及灌溉时间长短等多种因素有关。研究表明，中水灌溉对绿地植物的生长特性、抗逆生理、光合生理和营养水平有一定的影响，但不至于影响绿地植物的正常生长发育；中水灌溉不会造成绿地植物体内毒害离子如钠、氯、硼和重金属离子的大量累积，因此运用中水灌溉绿地是切实可行的。

Research progress on application of reclaimed water for irrigating greening plants

Reuse of reclaimed water was one of the most efficient means for resolving water shortage of city.The paper summarized the recent research work on the influence of reclaimed water to greening plants,which showed that there were positive and negative influences,and it was correlated with the quality of reclaimed water,irrigation models,plant species,soil type and irrigation time.The results showed that reclaimed water irrigation could affect plant growth characteristics,stress resistance physiology,photosynt...
