不知你是否留心过，钻天杨高于其它树木的原因在于没有横枝（即舍弃了横向发展），挺拔的身材只是一股劲地纵向往上生长着。类似的情形还有杉木和椰子树。它们其所以成为绿色植被中的尧尧旗手，令人仰面而视，实乃有所为有所不为也。与此相反，哪些横向发展的矮树，尤其是果树 I do not know if you have noticed that the reason why Tianying is higher than the other trees is that there are no horizontal branches (that is, the horizontal development is discarded) and the tall and straight body is only growing up vertically. Similar situations include fir and coconut trees. As a result, they became Yao Yao-bearers in the green vegetation, which made people look upside down. In contrast, what are the laterally developed shrubs, especially fruit trees?
