摘要
棉花是塔里木灌区主要种植作物。通过对该灌区历年滴灌面积、常规灌溉与滴灌棉花灌溉定额、单产及单方水效益等具体数据进行分析表明,棉花实施滴灌后每公顷可节水1 200 m3,计144元;到"十一五"末,滴灌比常规灌溉可节水约1亿m3;每公顷可使籽棉增产215 kg,计1 182.5元。
Cotton is the main crop in Tarim irrigation district. The actual datum, including drip irrigation area in past years, traditional irrigation and drip irrigation quota for cotton, unit yield and benefit per cubic meter of water, is analyzed in this paper. The result is obtained that drip irrigation for cotton can bring economic, ecological benefit and social benefit. For example water is saved by 1 200 m^3/hm^2 ,namely 144 yuan. Drip irrigation can lessen 108 ma water than traditional irrigation by the end of ＂the eleventh five year plan＂, and production increase by 215 kg/hm^2 , namely 1 182. 5 yuan.
