| 摘 要： | 本试验以乌盟地区主栽品种紫花白为材料,设置5个密度处理,采用通径分析及数学模拟等手段进行数据处理分析,得到的结果是:决定产量的主要因素是密度X_1与中薯重率X_7,其次是每株块茎重X_3和大薯重率X_4,无论是相关系数或通径系数或决定系数均达显著或极显著水平.进行逐步回归分析,计算结果的最优回归方程为: ??=516.4685+803.9325x_1+3.5125x_3+6.26x_4+13.775x_7

MATHEMATICAL MODEL OF YIELD COMPONENTS FOR HIGH YIELD POTATO POPULATION |
| |
| Abstract: | The cultivar Zihua Bai was used as the experimental material, and five treatments of density were carried out. The data obtained were analysed by the methods of path coefficient analysis and mathematical model. The results indicated that the density x_1 and percentage of intermediate tuber weight per hill x_7 were first important, and the tuber weight per hill x_3 and percentage of large tuber weight per hill x_4 second for yield determination in potato populations. The optimal regression equation, ??=516.4685+803.9325x_1+ 3.5125x_3+6.26x_4+13.775x_7 was established by means of stepwise regression. |
