摘要： [目的]以库尔勒市包头湖农场不同盐度棉田田间实测数据为基础,研究膜下滴灌灌溉制度对土壤水盐变化的影响,并选择合理的灌溉制度.[方法]试验根据相同灌溉定额,不同灌水定额、灌水时间间隔及灌水次数,选取低、中、高盐度棉田(每个棉田三个对照),共9个处理,同时将不同处理下不同盐度棉田灌溉水盐含量及产量进行对比.[结果]在灌溉定额一定时,低、中盐度棉田灌水定额为450 m3/hm2,灌水间隔为7d,次数为10对应处理洗盐效果最好且产量最高,高盐度棉田灌水定额为375 m3/hm2,灌水间隔为5d,次数为12对应处理洗盐效果最好且产量最高.[结论]灌溉定额一定,低、中盐度棉田适合中等灌水定额,高盐度棉田适合低灌水定额高频灌溉.
