In order to know the water migration of a new micro-irrigation technique of surge root irrigation,different water migrations of surge root irrigation were studied by cross-sectional method under different hold diameters and depths in the wild loess sloping fields.The results show that under different hole diameters and depths,there are different influences on the horizontal diffusion radius,the upward infiltration distance and the downward infiltration depth of wetting front,and all of them have remarkable ...
