Abstract
Based on the water infiltration experiments in field soil with different moisture content, effects of moisture content on cumulative infiltration, two infiltration parameters of Kostiakov infiltration equations, and the change of infiltration capacity of field soil was analyzed and discussed in this paper. The results indicated that infiltration capacity of field soil decreased while the moisture content increased. The relationship between two infiltration parameters and soil moisture content conformed to logarithm function law. The result is of practical meaning in determining the field irrigation technical parameters.
