| 摘 要： | 目的]研究冬小麦产量形成模型的构建。方法]以冬小麦品种石家庄8号为例,以动态设计思想为指导,采用均匀设计方法,研究了冬小麦生育期间产量性状的形成过程;应用多重比较方法,分别分析了不同生长阶段的植株干物重和群体指标的差异;利用多元回归分析方法,构建冬小麦产量形成模型。结果]干物质积累与群体指标的关系复杂;产量形成模型均达到极显著水平,其复相关系数介于0.91～0.97。结论]为小麦高产高效栽培提供理论参考。

| Abstract: | Objective]The aim was to research on construction of yield formation model of winter wheat.Method]In the case of winter wheat-Shijiazhuang 8,the process of yield trait formation were studied by dynamic ideal and uniform experimental design; by using multiple comparison analysis,the differences between plant dry weight and population indexes were analyzed; the yield formation model was constructed by multiple regression analysis. Result]The results showed that multiple correlation coefficients of yield formation model ranged from 0.91-0.97. Conclusion]The model was significant which provided certain theoretical reference for high yield and high efficiency cultivation of winter wheat. |
