摘要：This study was conducted under a dual Line Source Irrigation System (LSIS). Both LSIS covering 380 m2 (24 by 16 m) were laid out in a West-East direction and separated by a 15 m wide turf buffer zone. The LSIS in the east side received municipal potable water [Electrical Conductivity (EC) = 0.12 dS m-1]. The west LSIS received saline well water (EC = 3.0 dS m-1). Each LSIS was then equally divided into 12 plots in which Kentucky bluegrass and tall fescue were seeded in strips along the irrigation gradients. Data were collected on turf establishment, soil salinity , soil pH and drought responses. Saline well water irrigation increased soil salinity , sodium adsorption ratio and pH. Salty well water irrigation dramatically reduced and delayed the germination of Kentucky bluegrass, whereas tall fescue germination and establishment were unaffected when compared with potable water irrigation. Grasses subjected to well water irrigation exhibited greater iron chlorosis. Under moderate drought conditions tall fescue survived drought conditions better and required less irrigation to maintain acceptable quality. However, under severe drought conditions when soil moisture was depleted in deep soil profile, tall fescue did not show advantages in drought resistance over Kentucky bluegrass.
