摘　　要：河北平原水资源的日益短缺,冬小麦节水灌溉制度的研究对于农业节水将具有重要意义。根据望都试验站1991～1993两年的冬小麦试验资料,利用Jensen模型,建立冬小麦水分生产函数,求解出冬小麦作物敏感系数,编制二维动态规划程序,确定出冬小麦的灌溉制度。其结果与试验相吻合,可用于指导农业灌溉和生产。With the increasing scarce of water resources in Hebei plain, the research of water saving irrigation system on winter wheat will have important meaning for agricultural. According to the winter wheat experiment on 1991-1993 in Wangdutest station, establish winter wheat moisture production function using Jensen model(g) find the solution of sensitivity coefficient on winter wheat, build the 2 dimension dynamic operation program(g) the irrigation system of winter wheat has determined. Its result coincides with experiment, can be used to guide the agriculture irrigation and the production.
