Due to scarcity of water resources, reclaimed water irrigation is used more frequently, and its effect on plants has attracted much attention. In this study, enclosure sampling technique, GC/MS and LI-640 photosynthetic apparatus was used to study the volatilization of tall fescues, Kentucky bluegrass and ryegrass of northern urban greenbelt, which has been irrigated with reclaimed water, and compare the difference of volatilization between clean water and reclaimed water. The effects of reclaimed water irr...
