Delineation result based on the improved ant clustering indicated that the study area could be partitioned into two irrigation management zones. Soil field capacity, saturation moisture content and permanent wilting point in Zone I were greater than those in Zone II, which indicated that soil in Zone I had stronger drought resistance than that in Zone II under the same climate conditions. Delineation of irrigation management zones could provide references and data support for site-specified irrigation management.

By field and indoor test, the paper measures soil physical property, soilmoisture constant and soil water movement parameter, provides the soil specificgravity , the soil apparent density, the soil fraction, the soil field moisturecapacity, the soil saturated moisture capacity, the soil percent moisture content ofcom germination and seedlings emergence, the corn wilting point, and alsoestablishes the equation of soil water retention curves, the equation of soil waterdispersion coefficient and the relationship between pressure and soil apparentdensity, and so those provides the parameter for numerical simulation.
