摘  要:
以内蒙古河套灌区红卫节水示范园的咸水灌溉试验为基础,以荷兰Wageningen农业大学等单位开发的土壤—水分—大气—作物系统模拟软件SWAP为工具,应用示范园的土壤、水、盐分试验资料对模型的参数进行了率定和验证。在此基础上设计了示范园不同灌溉水量、不同灌溉方式、不同灌溉次数的多种灌溉方案,并应用SWAP模拟了各种方案的水盐平衡。以作物产量为指标,采用正交设计进行直观分析,提出了适合当地条件的以咸淡水轮灌作为灌溉方式,灌水3次,灌溉定额2812.5m3/hm2的咸水灌溉指导方案。研究结果对河套地区的咸水利用具有一定的借鉴意义。

摘  要:
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.
