摘　　要：本研究针对黄淮海冬小麦-夏玉米两熟区面临的出苗质量、播种—出苗期水分供应、灌溉施肥及时性及技术粗放等问题,并就进一步提高光温水肥资源利用效率是实现该区域粮食单产提升和绿色发展的重要途径等,从2018年起开展了一系列创新研究。通过实施冬小麦“四密一稀”条带种植配套卫星导航播种技术、冬小麦-夏玉米周年浅埋滴灌水肥药一体化技术等关键核心技术,结合配套现代化农机与信息技术装备,形成了一套集成的“冬小麦-夏玉米周年‘四密一稀’浅埋滴灌水肥药一体化绿色生产技术”。2010—2023年田间示范表明,该技术有效解决了上述生产难题,达到了小麦玉米周年增产和水肥资源高效利用的目标。与农民传统相比,小麦增产9%~17%,玉米增产12%~14%,周年节水450~750 m^(3)/hm^(2),节肥20%,节约人工成本2250~3000元/hm^(2)。该技术为黄淮海区冬小麦-夏玉米周年绿色高产提供了新的可行性方案。The Huang-Huai-Hai region is a significant production area for winter wheat and summer maize in China.Currently,the limiting factors include poor maize seeding quality due to no-tillage planting after wheat harvesting,difficulty in irrigation during the sowing to emergence period,untimely irrigation and fertilization,and poor farming techniques.Further enhancement of the use efficiency of radiation,temperature,water and fertilizer resources is the crucial way to achieve high grain yield and sustainable,green agricultural development in this region.To addresses these challenges,since 2018,we have innovated a comprehensive solution integrating several new technologies including the“four to one narrow-wide strip planting”for winter wheat,satellite-guided precision planting,annual shallow subsoil drip irrigation for synchronizing water-fertilizer-pesticide management.The corresponding modern agricultural machinery and information technology have been also matched.The integrated technique is called“Green water-fertilizer-pesticide synchronizing technology characterized of‘four to one narrow-wide strip planting’plus shallow subsoil drip fertigation for winter wheat-summer maize cropping system”.The field demonstration experiments conducted between 2010 and 2023 indicated that this novel comprehensive technology effectively addressed the aforementioned challenges and achieved both high yield and efficient resource utilization.Compared with traditional farmer practice,the new technology increased grain yield by 9%-17%in winter wheat and by 12%-14%in summer maize.The new technology also saved water input by 450-750 m^(3)/hm^(2),fertilizer input by 20%,and labor cost by 2250-3000 yuan/hm^(2).This comprehensive technology provides a novel feasible solution for the green and high-yielding production of winter wheat and summer maize in the Huang-Huai-Hai region.
