- Abstract:
-
A series of experiments were conducted to analyze the effect of drip flow,lateral depth and initial soil moisture on the moving speed of wetted peak under subsurface drop irrigation(SDI) in Latosol.The results showed that drip flow had more influence on the horizontal distance of soil wetted peak than that on the vertical one,the development of crop roots is mainly controlled by the drip flow.Lateral depth had little influence on the moving of wetted peak.The moving speed of wetted peak had been increasing along with the adding of initial soil moisture,and the increasing of horizontal distance was apparent.
