摘要
以冬小麦田间试验数据为基础,依据动态规划的原理,建立了冬小麦最优灌溉制度动态模型,通过对75 % 典型年的优化求解,得到了有限水资源充分利用的满意结果,提出了不同水文年型冬小麦最优灌水方案,可作为指导冬小麦田间管理时参考.
Based on the experimental data of winter wheat in fields and the theoty of dynamic plan,the optimal irrigation program of winter wheat is established.Satisfactory results are reached by optimizatim solution of 75% typical year.It offers the best irrigation scheme of winter wheat in different hydrological years.It also can be refered in the management of winter wheat between fields.
