Infiltration experiments were conducted by using double ring infiltration meter and the TST-70 indoor soil infiltration meter in the field for no irrigation, one irrigation and two irrigation times for soil bulk density of 1.35g/cm3 . The parameters of Kostiakov infiltration model were analyzed. The result showed that experience index α increased with irrigation times, and indoor experiment had a bigger α Simultaneously , the first unit time average infiltrates i0 in the Kostiakov infiltration model for indoor test and after irrigation had obvious reduction lowpared with no irrigation. The experience index α was less than relative reference. In four treatments, the accumulation infiltration of the one irrigation time and indoor experiment had a good helationship with the time. Therefore , when using the Kostiakov model to determine infiltration parameters for irrigation, the soil condition should be considered.
