Based on the vertical one-dimensional infiltration under the condition of –5 kPa, the water permeability of pot clay and PVFM in Chernozem zone A and zone B were analyzed. And the infiltration capacity, infiltration rate, humid peak and soil moisture content were measured and used to test the applicability of Kostiakov model, Horton model, Philip model and algebraic method of vertical one-dimensional unsaturated soil water movement in evaluating negative pressure infiltration, and further compared the model parameters under different treatments. The results indicate: 1) PVFM can replace pot clay as negative pressure infiltration device due to no significant difference in their measured accumulated infiltration; 2) Chernozem zone B has worse infiltration characteristics, less cumulative infiltration capacity and faster infiltration rate decrease compared with zone A in the same time; 3) In short time negative pressure irrigation, significant linear correlation exist between infiltration capacity and humid peak, between infiltration rate and reciprocal humid peak, between humid peak squared and time; 4) When using negative pressure irrigation, soil moisture contents within 15 cm up and down from infiltration device keep within 20%—33% with a variation coefficient of about 10%; 5) Fitting calculation proves that Kostiakov model and Philip model describe better the infiltration characteristics, while Horton model describes poorly in later period.
