Influence of reclaimed water irrigation on cool season turf growth

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 cultivar and Premier cultivar of Ryegrass (Lolium perenne), Barlexas cultivar and Easy care cultivar of Tall Fescue (Festuca arundinacea), Barvictor cultivar and Barrister cultivar 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.
