摘　　要：再生水用于草坪绿地灌溉对拓宽再生水的应用范围、缓解城市用水危机具有重要意义。本研究采用自来水和再生水两种水源灌溉供试草坪,分析其在再生水灌溉条件下的生长、生理指标的变化。供试草种为冷季型草坪草多年生黑麦草(Lolium perenne)品种潘多拉(Panterra)、首相(Premier),高羊茅(Festuca arundinacea)品种凌志(Barlexas)、易凯(Easy care),草地早熟禾(Poa pratensis)品种百胜(Barvictor)、百斯特(Barrister),研究结果表明,再生水灌溉使各草坪草的再生量提高,叶绿素含量也显著提高,灌溉后期草坪草叶宽显著提高,但对叶片细胞膜透性和根系活力没有显著影响。再生水用于草坪灌溉在兰州市具有良好的应用前景。Reclaimed water can be used in lawn irrigation, which can broaden the application range of reclaimed water and ease the tension of water use in city. In this experiment, both tap water and reclaimed water were used in lawn irrigation test. Cool-season turf grass including Panterra cuhivar and Premier cul- tivar of Ryegrass （Lolium perenne）, Barlexas cultivar and Easy care cultivar of Tall Fescue （Festuca arundinacea）, Barvictor cuhivar and Barrister cuhivar of Kentucky bluegrass （Poa pratensis） were used as materials, and their changes of physiological indicators under reclaimed water irrigation were studied. The results show that reclaimed water irrigation can improve lawn texture and remarkably raise the leaf width of turf grass. Additionally, the grass chlorophyll content under irrigation test of reclaimed water was significantly higher than that under tap water irrigation, and there was no significant difference in the leaf cell membrane permeability and root activity between grasseses under irrigation conditions. In short, reclaimed water irrigation for turf grass has a very good application prospect in Lanzhou.
