| Abstract: | In August and September,2010,by use of electronic balance and Li-6400 photosynthesis system,the evapotranspiration,transpiration rate,water using rate and soil water content of three kinds of ground cover plant commonly used in landscape.The results showed that under different irrigating conditions,evapotranspiration increased with the irrigation amount at different increasing range.The mean transpiration rate was Iris lactea var.chinensisPotentilla anserinaSedum spectablile,and treatment ⅢⅡⅠ.The water using efficiency was Sedum spectablileIris lactea var.chinensisPotentilla anserina.The effect of soil water content on transpiration rate was significant（P0.01）,with a linear relationship between soil moisture and transpiration rate. |
