很多研究资料指出,文冠果大面积栽植,其单位面积产量较低的主要原因是类型混杂,单株间产量相差悬殊。因此,近十年来各地从现有母树中已筛选出一批具有座果率高、种子产量高、产油量高、抗逆性强和连续丰产等性能的不同类型优良单株。本文拟从光合作用强度及有机养料输导与丰产的相关性方面,对优树丰产特性作一些粗浅的探索,以期对正在开展的选优工作有所助益。 A lot of research data pointed out that the large-scale planting of Wen Guan Guo, its low yield per unit area is mainly due to the type of hybrid, a significant difference between the yield of single plant. Therefore, in recent ten years, a batch of fine plants with different types with high fruit yield, high seed yield, high oil yield, strong resistance and continuous high yield have been screened from the existing mother trees. This paper intends to make some superficial exploration on the yield characteristics of elite trees from the aspects of the photosynthesis intensity and the correlation between the organic nutrient transport and high yield, in the hope of helping the ongoing optimization work.
