| 农业灌溉耗水量巨大，在农田建设中推广应用高效节水灌溉技术是解决水资源短缺的关键。本研究以华北地区冬小麦为研究对象，基于地下滴灌技术+膜调控技术，研究膜调控地下滴灌技术对冬小麦耗水和产量的影响。研究结果显示，在膜调控地下滴灌技术下，冬小麦棵间蒸发强度在整个生育期内一直处于一个较低水平，日平均棵间蒸发强度比传统畦灌减少了32.73%~40.00%；与传统畦灌相比，膜调控地下滴灌技术冬小麦的耗水量同比减少了 15.00%~19.14%，产量同比最大可提高19.46%，水分利用效率同比提高了22.72%~40.40%；此外，膜调控地下滴灌技术下，冬小麦基础作物系数Kcb随着生育阶段的推进呈现出先增大后减小的趋势，与 FAO-56推荐值的变化趋势基本相符。膜调控地下滴灌技术具有显著节水和增产效应，符合国家节水行动的要求，为雄安新区及河北平原区的农业水资源管理提供新思路。 |

| Agricultural irrigation consumes a large amount of water. Popularizing and applying high-efficiency water-saving irrigation technologies in farmland construction is key to addressing water resource shortages. This paper took winter wheat in North China as a case study and， based on subsurface drip irrigation technology and membrane regulation techniques， analyzed the effect of membrane-regulated subsurface drip irrigation technology on water consumption and yield of winter wheat. The results show that compared to traditional border irrigation， the evaporation intensity of winter wheat plants under membrane-regulated subsurface drip irrigation technology remains a relatively low level in the entire growth period， and the daily average evaporation intensity reduces by 32.73% to 40.00%， the water consumption reduces by 15.00% to 19.14%， the yield of winter wheat increases by up to 19.46%， and the water use efficiency improves by 22.72% to 40.40%. Additionally， the basal crop coefficient （Kcb） of winter wheat shows a trend of increasing first and then decreasing under membrane-regulated subsurface drip irrigation technology as the growth stage progresses， and this trend is generally consistent with the change tendency recommended by FAO-56. Membrane-regulated subsurface drip irrigation technology has significant water-saving and yield-increasing effects， meeting the requirements of the national water-saving initiative. The technology can provide new insights into agricultural water resource management in the Xiong'an New Area and the Hebei Plain region. |
