本试验用单相关系数比较法和多重回归分析法综合考察了一些与腰果产果有关的生长和开花因子。结果表明,花开的多少是决定腰果产量的首要因子,其次是树冠面积,两性花开放的百分率对产量亦有显著影响,落果率与产量呈负相关,树高对产量无显著影响。
In this study, we used a single correlation coefficient comparison method and multiple regression analysis to examine some of the growth and flowering factors associated with cashew nuts. The results showed that the number of flowering was the most important factor in determining the yield of cashew nuts, followed by the canopy area. The percentage of openness of flowers was also significantly affected by yield, the fruit loss rate was negatively correlated with the yield, and the tree height had no significant effect on the yield.
