摘　　要：采用对净灌溉需水量作频率分析的方法,确定不同灌溉典型年;通过多年资料,利用乘法模型计算得出不同年份烤烟各生育阶段水分敏感指数;利用节水灌溉制度优化设计的动态规划逐次渐进法,对烤烟不同水平年的灌溉制度进行了动态优化设计。结果显示,该模型充分反应了灌水时间、灌水定额、灌溉水量产生的烤烟产量效应,所建模型和参数确定较合理,实用性较强。This paper is an attempt to determine different typical years by analyzing the frequency of the net irrigation water supply. Combined with material of tobacco water-saving irrigation experiments in Enshi Autonomous Prefecture, Hubei Province, the authors optimally designed the irrigation procedures of tobacco in different typical years based on the successive asymptotic of dynamic programming. Results show that less water is needed to obtain more potential and that the model established and the parameter are rational and practical.
