[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奠定理论基础。
[Objective] The research aimed to study the construction of winter wheat yield formation model. [Method] Taking the winter wheat cultivar Shijiazhuang No.8 as an example, using the dynamic design idea as a guide, the uniform design method was used to study the formation process of yield traits during the growth of winter wheat. The dry weight of plants at different growth stages was analyzed using multiple comparison methods. And the difference of population index. Using the multiple regression analysis method, the wheat winter wheat yield formation model was constructed. [Result] The relationship between dry matter accumulation and population index was complicated. The yield formation models reached extremely significant levels with complex correlation coefficients ranging from 0.91 to 0.97. [Conclusion] It laid the theoretical foundation for high yield and high efficient cultivation of wheat.
