沈阳地区冬小麦水分生产函数与水分敏感指标的初步研究

Water Production Function and Sensitivity Index to Water Deficit for Winter Wheat in Shenyang Region

根据沈阳地区1999～2001年的试验资料 ,研究了冬小麦不同生育阶段缺水对其产量的影响 ,并采用Jensen模型推求了冬小麦的水分敏感指标 ,分析了沈阳地区冬小麦水分敏感指标的变化规律 ,得出了初步的水分生产函数模型 ,为沈阳地区冬小麦的非充分灌溉研究提供了参考和借鉴。

Based on the experimental data in1999～2001in Shenyang,water-deficit effect on the yield of winter wheat under differˉent growth stages was studied.With Jensen model,winter wheat moisture sensitivity index was determined and its changes were anaˉlyzed.The preliminary water production function was obtained,which could provide reference for winter wheat insufficient irrigation in Shenyang region.
