摘　　要：我国粮食需求增量与耕地减少的矛盾已然成为焦点,尤以北方干旱半干旱地区水资源严重不足更显突出。提高农业水资源利用效率,完善节水高效灌溉体系,提高作物产量已势在必行。针对河南洛阳半干旱地区主要种植模式———冬小麦夏玉米连作,通过作物需水特征分析、生育期降水时序耦合分析,突出一水两用理念,控制水分胁迫时间,依据旱作物土壤计划湿润层水量平衡方程提出最佳供水过程。同时,考虑不同灌溉技术条件下的适宜灌水技术参数,探索不同灌溉方式的灌水量、灌水时间以及实施办法,最终提出不同频率年、不同灌溉模式的适宜灌溉制度。Abstract： Food demand increment and the reduction of arable land has become the focus of the conflict, especially in arid and semi-arid areas of northern severe water shortage is even more prominent. Improving agricultural water use efficiency, water conservation and efficient irrigation system and improving crop yield are imperative. Against the serious problems in water-saving irrigation, this paper investigated the characteristics of water requirement , highlighting a dual concept of water, control of water stress time, and the best water supply process based on upland crops plan wet- ting layer soil water balance equation in wheat-maize rotation mode considering the characteristics of Luoyang semi-arid region. According to tile dif- ferent irrigation modes, the suitable technical parameters and the exploration of irrigation quantity, irrigation time and implementing method were analyzed based on field experiments. Finally, the suitable irrigation schedules in wheat-maize rotation mode in different frequency years and differ- ent planting patterns were proposed.
