1992~1996年在商丘试验区进行了“冬小麦-夏玉米节水高效吨粮水肥耦合及其配套技术”试验研究和示范应用。探讨了吨粮田建设的生态环境指标,提出了节水高效吨粮田综合技术,即以水肥耦合及其优化运筹为关键技术,通过品种搭配、灌水技术和土壤-植物系统水分调控等技术的综合集成,实现节水节肥、高产高效、合理利用资源和保护环境的目标。经1万亩示范应用,平均年亩产1041kg;水分利用效率(WUE)2.07kg/m3,比一般田高1.0kg/m3;N化肥利用率44.9%,比一般田高13个百分点;亩产值增加72.5%,亩盈利提高1134%,劳动生产率提高31.13%;综合技术在经济效果中的作用占45.36%。
From 1992 to 1996 in Shangqiu experimental area, “winter wheat - summer corn water-efficient and efficient tonnage of water and fertilizer coupling and supporting technology” experimental research and demonstration application. This paper discussed the eco-environment index of the construction of the grain-grain field and put forward the comprehensive technology of water-saving and high-efficiency ton grain field, that is, the key technology of water-fertilizer coupling and its optimization, through the combination of variety, irrigation technology and soil-plant system moisture regulation Integrated and integrated to achieve the goal of saving water and fertilizer, high yield and high efficiency, rational use of resources and protection of the environment. The average annual yield per mu is 1041kg; the water use efficiency (WUE) is 2.07kg / m3, which is 1.0kg / m3 higher than the average farmland; N fertilizer utilization rate is 44.9%, which is 13% The output value of mu increased by 72.5%, the profit of mu increased by 1134% and the productivity of labor increased by 31.13%. The effect of comprehensive technology in economic effect accounted for 45.36%.
