Experimental Study on Urban Turfgrass Evapotranspiration from Yinchuan City,China
Based on the experiments, soil water contents of urban turf field and evapotranspiration of urban turf and highway green belt turf were analyzed with different irrigation methods in Yinchuan city,China. The results showed that the variation pattern of turf crop coefficient Kc in the three experimental sites was same as soil water content and turf reference evapotranspiration. The values of Kc changed obviously in different months. The mean of Kc for urban turf from sprinkler irrigation was lower than urban turf and highway green belt turf with flood irrigation, while mean of Kc for highway green belt turf with flood irrigation was highest. Similarly, the evapotranspiration (or water consumption) of urban turf irrigated with sprinkler method was less and the growth situation was better than urban turf and highway green belt turf with flood irrigation method. Evapotranspiration for highway green belt turf with flood irrigation was most and its growth situation was worst among three experimental sites.
