摘　　要：通过对试验区葡萄基地进行监测并对监测结果分析研究表明:在地下水浅埋条件下的干旱内陆河灌区,无排水条件下采用滴灌灌溉方式十分有效。可以充分利用滴灌的干排盐功能把作物根区的土壤盐分排积到行间无效空间区域,减少洗盐、排盐的淡水资源;在距滴头越近的土体,土壤盐分运动越剧烈,滴灌后,在有效浸润土体范围内,土壤盐分的浓度可迅速降低,适宜的滴灌频度,可长期保证有效浸润土体内土壤盐分浓度保持在较低的水平;研究区葡萄基地现状滴灌状况下,目前的滴灌制度不合理,灌水量不够,灌溉周期略长。虽然干排盐效果明显,但排盐和土壤浸润范围不能满足葡萄的正常生长,也不能保证葡萄基地建设生产的可持续性发展。According to adynamic analysis of monitoring experiments for soil water, soil salt and ground water transport in soil in arid inland river irrigation regions. This paper is an attempt to reveal the dynamic change regularities of soil profile salinity in the cotton growing periods proces, and draw up the science moisture content management and the salinity management measure for the cotton growth. Groundwater I uctuation can warn development of agricultural field salinization, It can help adjust irrigation quota and take preventive measures.
