摘要
2002年在内蒙古河套灌区红卫节水示范园进行了咸水灌溉试验,分析试验结果得出:咸水灌溉下的土壤经过秋浇后含盐量可以降到咸水灌溉前水平。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,模型模拟结果和田间试验结果符合较好。
The fresh water resource is scarce in the Hetao Irrigation District. Therefore, it is of importance to study saline water irrigation and its impact on soil salinity balance. A saline water irrigation experiment was conducted in Hongwei Water Saving Irrigation Experiment Station during the growing period of sunflower and spring wheat, from middle of Apr. to the end of Nov. in 2002.The results of experiment show that the accumulated salt because of saline irrigation can be removed by the autumn irrigation.SWAP (SoilWaterAtmospherePlant) model developed by Wageningen agricultural college were used as aanalyzing tool. The parameters in the model were calibrated with the data of the saline water irrigation experiment.
