中文摘要: 分析冬小麦越冬前后叶龄变化，温度有效性随播期、发育期变化及其对叶龄的影响。用样条回归方法，建立了叶龄与有效积温模式，并用该模式确定冬小麦适播期以及插补缺测的叶龄。
中文关键词: 冬小麦,叶龄,有效积温,样条模式
Abstract:A spline regression model was used to describe the relationship between the leaf age and the accumulated effective temperature, based on analysing the change of leaf age of winter wheat during the pre-and post-overwinter period. Interpolation of leaf age data was made and the optimal seeding date was decided with this model.
