In order to solve the problem of congestion in subsurface drip irrigation and to promote application of subsurface drip irrigation to forest or fruit industry, the design principle and the design requirements of model anti-clogging of subsurface drip irrigation system were proposed. These data of the system were obtained that the system pressure was 15~25kPa and the plughole spacing was 300mm, and that the distance between inner wall of protective tube and out wall of capillary was 40mm and the irrigation uniformity is more than 85% through experiment. Effects on the growth of Cabernet Sauvignon by the system show that anti-clogging subsurface drip irrigation (SDI) and drip irrigation under plastic film (MDI) compared with conventional drip irrigation (DI) can maintain the stability of soil moisture content in 20~60cm, and increase ratio of root to shoot and the effective root surface area, so as to accelerate root turnover and renewal, and enhance the absorptive capacity of plant roots to soil moisture and nutrient.
