【摘要】 针对新疆日益盛行的膜下滴灌技术和残膜污染的问题,提出将无膜移栽与地下滴灌相结合,形成无膜移栽地下滴灌集成技术,既可充分发挥移栽和地下滴灌的优势,提高水分利用率,又可有效减缓白色污染。本文以小区试验为基础,地下滴灌灌溉定额和灌水次数相同情况下,将无膜移栽棉花和覆膜直播棉花的生长发育情况和产量进行比较分析,结果表明:地下滴灌无膜移栽棉花比覆膜直播棉花生育进程有所提前,叶片数较多,株高较低,果枝数和铃数相当,脱蕾铃率较低,单株叶面积较大,叶面积指数较大,在耗水量相当的情况下,无膜移栽棉花比覆膜直播棉花水分生产率和产量均占有一定的优势,研究结果将为推动无膜移栽地下滴灌技术的发展提供一定的理论依据和技术支持。更多还原

【Abstract】 Directed at both the increasing under-mulch drip irrigation technique and the problem of residual plastic film in Xinjiang,transplantation without film was in combination with subsurface drip irrigation,forming the transplantation without film subsurface drip irrigation integrated technique.The technique not only gave play to the advantages of transplantation and subsurface drip irrigation,improving moisture utilization rate,but also decreased the white pollution efficiently.Based on the field experiment,under the same conditions of irrigation quota and irrigation times with subsurface drip irrigation,in comparation with the cotton growth condition and yield between transplantation without film and seeding with film,the results show that:under the subsurface drip irrigation,the cotton growth process of transplantation without film is earlier than the seeding with film,the leaf blades of the former is more than the latter,but the plant height is relatively low,the number of fruit branch and the number of bolls are equivalent, the sulfur fertilizer rate is relatively low,the single leaf area is relatively big,the leaf area index (LAI) is relatively bigger,under the same water consumption,the cotton moisture production rate and yield of the transplantation without film have superiority to the seeding with film,research results offers certain theory basis and technique support for promoting the transplantation without film subsurface drip irrigation technique.更多还原
