Abstract:: In order to determine the effects of aquasorb with different mixed-application dosages on characteristics and dynamic changes of soil water infiltration, the dynamic changes of infiltration rates, cumulative infiltrations, and wetting front of soil water under aquasorb were analyzed through the lab experiments. The results showed that the mixed-application aquasorb reduced the infiltration rates, the cumulative infiltration and the move distance of the wetting front. The more the mixed-application dosages of aquasorb is applied, the greater the inhibition degree on the infiltration rates is, the cumulative infiltration and the move distance of the wetting front were smaller. When the dosages of aquasorb were 0.75% and 1.00%, the surface soil moisture was increased sharply; meanwhile, the soil moisture in 8-14 cm layer was lower because of the role of the larger penetration resistance. When the dosage of aquasorb was 0.50%, the soil moisture in 8-14 cm layer was more.
