Temporal Variation of Soil Steady-state Infiltration Rate Under Typical Cultivated Land in Hilly Region of Loess Plateau
[Objective] The temporal variations of soil steady-state infiltration rate under typical cultivated lands were studied and the potential factors causing those changes were explored in order to provide theoretical bases and data support for soil erosion control
soil and water conservation
and the utilization of limited water resource in the Loess Plateau. [Methods] Using two-ring infiltration experiments
the temporal variations of soil steady-state infiltration rate under typical cultivated lands were studied. [Results] The temporal variations of soil steady-state infiltration rate under typical cultivated lands fluctuated significantly over time and displayed different temporal patterns(p < 0.05). Significant differences in soil steady-state infiltration rate were found between croplands and a bare land(p < 0.05). Among the croplands
the maximum mean soil steady-state infiltration rate occured at area planted with potato
and followed by a soybean land
and a millet land. The temporal variations in soil steady-state infiltration rate were closely related to agriculture activities
dry bulk density
total porosity
and root growth. [Conclusion] The temporal variations of soil steady-state infiltration rate under typical cultivated land displayed significantly different temporal patterns during one growing season(p < 0.05)
which was mainly affected by agriculture activities
dry bulk density
total porosity
and root growth.
