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.
