But with the shortage of water resources and water demand increases every year the contradiction between growing, traditional irrigation is gradually being precise focus on the modern irrigation water-saving irrigation replaced by the model. in this paper, the status of economic development, to the new Ken Country and Talim rural cotton farms and drip irrigation projects as an example, the use of input-output analysis, combined with cost-effective method of drip irrigation for cotton economic analysis, Resulting in drip irrigation of cotton in the problems faced by, and in light of the realities of life given the problems facing the possibility of reasonable proposals，That pressurized drip irrigation of cotton yield significant results, bringing the overall efficiency. Key words：Drip irrigation; otton; Economic benefits 滴灌是近些年来各地试验推广的一项灌溉技术它比地面具有明显的增产、省水、省工、改良土壤、提高作物产品质量等多种效果,滴灌工程发展的较快。沙雅县是全国优质棉生产县，200年棉花产量达吨，皮棉总产达到了6.89万吨居全国植棉大县（按产量）第二位。然而，近年来由于水资源匮乏，限制了沙雅县棉花产业的进一步发展。沙雅县是有名的棉花百万担大县，也是近年来发展最
