Experimental research on saline-water irrigation in Hetao Irrigation District

Based on field experiments of the saline water irrigation which have been conducted in the Hongwei Water Saving Demonstration Plot in Inner Mongolia Autonomous Region, SWAP(Soil-Water-Atmosphere-Plant) model developed by Wageningen Agricultural College was used as an analyzing tool. The parameters in the model were calibrated with the data of this saline-water irrigation experiment. Then, different irrigation schedules of saline-water irrigation based on the different irrigation rations, the different irrigation times and the different irrigation types were simulated and the results were analyzed, the optimal irrigation schedule was selected.
