This paper reported evapotranspiration of Puccinellia chinampoensis growing on a saline soil under irrigation with different salt solutions and plain water. In condition of equal water supply, evapotranspiration of P. chinampoensis was negatively correlated with salt concentration of the irrigated water. Evapotranspiration of the plant waw controlled by amount of salt accumulated in the soil. When soil salinity had increased from original 1.13% to 1.33% and above, evapotranspiration of the plant decreased s...
