摘　　要：灌排两用地下节水灌溉技术可以有效的提高田间水分的利用率,具有"旱时吸水,涝时排水"的功能,达到旱涝保收的目的;并且该灌溉技术能够降低病虫害的发生,减少因肥料流失造成的水污染,克服了目前几种常见的灌溉技术的缺陷。The reasonable layout of pumping wells is very important for the development and utilization of groundwater resources in the well-canal combined irrigation district in north China.Taking Baojixia irrigation district as an example,on the basis of the groundwater resources evaluation,groundwater utilization typical areas are divided.According to the mining-supplement characteristics,different plan-design methods are taken.As a result,the preliminary adjustment programming of current pumping wells layout are put forward.
