| 摘 要： | 应用逐步回归分析法和通径分析法研究油茶树体结构与产量的关系.结果表明:冠幅、树高、枝下高和骨干枝数4个油茶树体结构因子对产量有显著性影响,其中骨干枝数与油茶单株产量的关系最密切.并得到了4个树体结构因子与单株产量的多元线性回归方程及通径系数,说明在保证一定树高的生长条件下,增加冠幅,促进培养骨干枝数的数量,降低枝下高,...

| Abstract: | Based on stepwise regression and path analysis,the relationship between the tree composition and yield of Camellia oleifera was examined.It was found that four factors of tree composition including the crown width,the tree height,the clear bole height and the number of scaffold branches have significant impact on yield and the number of scaffold branches has closest relationship with the yield per plant.The multiple linear regression equation and the path coefficient between the four factors and yield per p... |
