The characteristics of soil water infiltration to different salt contents soils are the basis for accurate acquiring soil hydraulic parameters.Based on the infiltration experiments using a disc infiltrometer,the characteristics of the soil water movement under the different negative heads(-1,-3,-6,-9 and -12 cm)for 4 soils with different soil salt contents were analyzed.The results showed that with the decrease of the negative head,the parameters including the sorptivity, the steady infiltration rate,the un...
