大树移植一次成功,已成为城市森林建设的重要技术。但这种技术多适合于萌芽能力较强的阔叶树,如樟树,成活率稍高;但对于针叶树,如松树却很难移植成功。因为这种技术的技术要点是截枝断根,把大树做成亚铃状,种植于城市。种植后,要过成活关、扎根关、长枝关。即使成活,由于大根都截断,要重新扎牢土壤,至少需10年时间。这10年内稍有大风,就可能被吹倒,由于大枝都截断,要重新长成大树冠最起码要10年,这10年内树木的光合作用都是负值,即二氧化碳释放得多,氧气制造得少,失去了树木本身最基本的生态功能。
The successful transplantation of large trees has become an important technology in urban forest construction. However, this technique is more suitable for broad-leaved trees with strong germination capacity, such as camphor trees, with a slightly higher survival rate. However, it is very difficult for conifers such as pine trees to be transplanted successfully. Because the technical point of this technique is cut off branches, the tree made of bell-shaped, planted in the city. After planting, to live off, take root, long branches off. Even if it survives, it will take at least 10 years to cut it off because of its large roots. This 10 years a slight wind, it may be blown down, because the large branches are cut off, to re-grow into a canopy at least 10 years, 10 years of photosynthesis of trees are negative, that is, the release of much carbon dioxide, oxygen Fewer, lost the most basic ecological function of the trees themselves.
