Experiments on factors affecting ponding time under soil infiltration conditions

In order to study the effects of water supply intensity, soil bulk density, initial soil moisture and soil texture on infiltration ponding time under the condition of non-sufficient water supply, and build mathematical relation on infiltration ponding time and each factor, infiltration experiments with eight kinds of homogenized soils under non-sufficient water supply condition were conducted indoors. The results showed a negative-exponent power function relationship between water supply intensity and infiltration ponding time, and logarithmic function relationship between soil bulk density, initial soil moisture, soil texture and infiltration ponding time. The research is of an important significance for studying soil and water conservation and hydrology runoff, and also of practical meaning for instructing the design of sprinkler irrigation system.
