摘　　要：在盆栽试验的基础上进行了无膜移栽、覆膜移栽、覆膜直播3种处理棉花地下滴灌小区对比栽培试验,分析了覆膜和移栽对地下滴灌棉花植株形态指标及产量的影响。结果表明,移栽技术对地下滴灌棉花的生长发育具有积极的促进作用,有利于在保持地下滴灌较高水分利用率的基础上继续提高棉花产量和水分生产率,薄膜的覆盖有利于移栽棉花及早渡过缓苗期而进入生殖生长阶段,但后期薄膜覆盖的影响基本消失,移栽而不采用薄膜覆盖对地下滴灌棉花总体影响不大,甚至有增产和提高籽棉品质的作用,在北疆地区采用棉花无膜移栽与地下滴灌相集成的新技术完全可行。Three disposals of no-film transplanted, filmed transplanted and filmed seeded subsurface drip irrigation plots contrasted cultivation tests was carried on, which is based on the pot cultivation tests, and the infection of filmed and transplanted on subsurface drip irrigated cotton plant growth parameter and yield were analyzed. The results indicates that the technology of transplantation has active effect on subsurface drip irrigation, and it is propitious to go on improving cotton yield and WUE under the high WUE of subsurface drip irrigation. Using of film is propitious to help the transplanted cotton get through rejuvenation period and enter into reproductive growth stage as soon as possible, but the effect of filming is disappeared at late growth stage. The whole effect of transplanting without film on subsurface drip irrigated cotton is not serious, which even can improve the yield and quality of seed cotton. It is suggested that the application of the new integration technology of subsurface drip irrigation and cotton transplantation technology is completely feasible in the north of Xinjiang Autonomous Region, and it is propitious to continuable and high efficiency development of cotton planting of Xinjiang.
