摘  要：
地下滴灌可能是最复杂、节水效率最高的技术,将地下滴灌和无膜移栽技术结合起来会发挥更大的综合效益,以6个测坑为试验基础,在灌溉定额相同的情况下,研究了不同移栽时间对地下滴灌棉花生理形状及产量的影响,从而确定最佳的移栽时机,即移栽期内适宜的日平均气温为18.4~20℃,日最高气温为26.2~27.2℃,地下10cm日平均地温为20.92~22.22℃,日最高地温为27.5~28.1℃;15 cm日平均地温为20.26~21.41℃,日最高地温为24.6~25.1℃;移栽后10天日气温最低有效积温为66.46~70.65℃,日气温最高有效积温为78.08~83.28℃,地下10 cm日地温有效积温为104.72~106.71℃,为推动地下滴灌技术的发展提供一定的参考。

摘  要：
Subsurface drip irrigation may be the most complicated,the most efficient water saving irrigation technique.Its combination with transplantation without film will give more comprehensive benefits.Based on six measured hole for experiment,under the same irrigation quotas,the influence of different transplantation time on physiological character and yield of cottons under subsurface drip irrigation is studied in order to determine the best transplantation time.The result shows that during the transplantation time,the suitable daily average temperature is 18.4~20℃,the daily highest temperature is 26.2~27.2℃,the daily average geotemperature underground at 10 cm is 20.92~22.22℃,the daily highest geotemperature is 27.5~28.1℃,the daily average geotemperature underground at 15 cm is 20.26~21.41℃,the daily highest geotemperature is 24.6~25.1℃,the lowest daily effective accumulated temperature after transplanting ten days is 66.46~70.65℃,the highest daily effective accumulated temperature is 78.08~83.28℃,the daily effective accumulated geotemperature underground at 10cm is 104.72~106.71.The study result offers reference for the development of subsurface drip irrigation.
