| 摘 要： | 应用逐步回归和方差分析方法，证实枝条的P含量对板栗丰产具特性上的二次生长及结实存在着互相制约的负相关，这种相互制约的关系不仅可避免板栗生产上常见的大小年现象，而且为实现第一次结实量与第二次结实量的人工调控提供了可能。

| Abstract: | The correlation study was conducted using step by step regression and variance analysis. Results showed that the content of phosphorous in the shoot plays a positively crucial role in the nut yield because of its great impact on the number of female flowers germinated and the size of the bearing shoot. It was also found that this re bearing chestnut tree, which bears twice a year biologically, is negatively correlated in growth and fruiting, thus avoiding the common phenomenon of on year and off year and enabling the horticultural control over the first crop and the second crop of the year to be possible. |
