摘　　要：如何提高棉花幼苗保苗率是夺得农业增产丰收的重要前提条件。本文以新疆孔雀河流域为例,对不同灌溉方式与出苗水量对棉花幼苗保苗情况的影响进行了系统分析,结果表明:在高盐渍化土壤采用750m^3/hm^2出苗水量与滴水出苗方式,其保苗率最高,达70%;在低盐渍化土壤采用750m^3/hm^2出苗水量与双膜覆盖方式,保苗率最高,达89%。研究结果为指导当地棉花灌溉方式的合理选择及棉花种植业发展提供了重要参考。How to improve the seedling rate of cotton seedling is an important precondition for yield increase and harvest of agriculture. In the paper,Xinjiang Kongque River Basin is adopted as an example for systematically analyzing the influence of different irrigation methods and seedling water amount on cotton seedling protecting condition. The results show that:750 m^3/hm^2 seedling water amount and drip irrigation seedling mode are adopted in the high salinization soil. The seedling protection rate is the highest,namely 70%. 750 m^3/hm^2 seedling water amount and double-membrane coverage mode are adopted for low salinization soil,and the seedling protection rate is the highest,namely 89%. The results provide an important reference for guiding reasonable selection of local cotton irrigation methods and development of cotton planting industry.
