根据内蒙古河套灌区秋浇节水与土壤盐渍化防治的需要,利用SHAW模型模拟确定了不同盐渍化土壤合理的秋浇节水灌溉制度.结果表明:对于轻度盐渍化土壤,秋浇定额一般为142～183 mm,秋浇时间为9月28日-10月23日;对于中度盐渍化土壤,定额应该为180～200mm,时间在10月14日-18日;对于重度盐渍化土壤,一般不种小麦,而种葵花等耐盐作物,定额为200～225 mm.因此,对于该灌区应该根据不同的土壤盐渍化程度,合理地安排秋浇.
根據內矇古河套灌區鞦澆節水與土壤鹽漬化防治的需要,利用SHAW模型模擬確定瞭不同鹽漬化土壤閤理的鞦澆節水灌溉製度.結果錶明:對于輕度鹽漬化土壤,鞦澆定額一般為142～183 mm,鞦澆時間為9月28日-10月23日;對于中度鹽漬化土壤,定額應該為180～200mm,時間在10月14日-18日;對于重度鹽漬化土壤,一般不種小麥,而種葵花等耐鹽作物,定額為200～225 mm.因此,對于該灌區應該根據不同的土壤鹽漬化程度,閤理地安排鞦澆.

In accordance with the prevention of soil salination and water-saving irrigation in autumn in Inner Mongolia Hetao irrigation district, the reasonable water-saving irrigation scheme in autumn was quantificationally established by using SHAW model in theory, which aimed at the different salinized soils. For slight salinized soils, autumn irrigation quota was from 142 to183 mm between September 28 and October 23. For moderate salinized soils, autumn irrigation quota was from 180 to 200 mm between October 14 and 18. For serious salinized soils, planting sunflower instead of wheat autumn irrigation quota was from 200 to 225 mm. In the studied irrigation district, autumn irrigation is supposed to be reasonably arranged according to the different salinized soils.
