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殊重要作用 ,它在很大程度上与雌花数量、结果枝粗度和结果母枝粗度密切相关 ;也证实了二次结实板栗自身生物学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。
The application of stepwise regression and analysis of variance showed that the P content of shoots was of special importance for the high yield of Chinese chestnut. It was closely related to the number of female flowers, the thickness of the branches and the thickness of the parent branches. It was also confirmed that the secondary consolidation Chestnut its biological characteristics of the secondary growth and fruiting there is a negative correlation with each other constraints, the mutual restraint of the relationship not only to avoid chestnut production common size year-round phenomenon, but also to achieve the first time the amount of solid and the second Robust regulation of labor provides the possibility.
