| Abstract: | With a mathematical model, soil water movement under subsurface irrigation was simulated with different soil characters, initial soil water content, pipe position, water pressure and duration of water supply. The influences of these factors to subsurface irrigation performance also are discussed and some relevant design parameters are presented in this paper. As a sample, the application of subsurface irrigation in vegetables in greenhouse is introduced. |
