摘要(Abstract):

【目的】提高南方大型平原自流灌区农业用水效率,发展精准灌溉。【方法】针对江苏省洪金灌区,基于降雨短期预报和水量平衡方程,开展水稻灌溉制度的实时优化研究。【结果】基于7 d短历时天气预报,2017年7月7─13日洪金灌区采用实时优化方法确定的灌溉方案与传统灌溉制度相比,在满足同样灌水要求情况下的灌溉水量减少了32%。【结论】该方法对南方水稻区种植具有普遍指导意义,能够更加精确地安排水稻灌溉制度,提高雨水利用率,优化地区水资源分配。
【Objective】Improve efficiency of agricultural irrigation and develop precision irrigation in southern large-scale irrigation districts.【Method】A research on optimization of irrigation schedule for paddy in a irrigation area based on precipitation forecast and water balance equation in Jiangsu was conducted in this paper. The method was applied to Hongjin irrigation area.【Result】Based on the 7-days short-term precipitation forecast, irrigation water derived from the real-time optimal irrigation schedule from July 7 to July 13, 2017 was 32% less than that derived from the traditional irrigation schedule under the same irrigation requirements.【Conclusion】The proposed method may provide reference for paddy irrigation in the south. It can determine paddy irrigation schedule more accurately, improve rainwater utilization and optimize regional water resource allocation.
