贴上我的作业,请指教 The lecturer described a special process of pruning which run against the good use of pruning, that is topping, which means heavy pruning on top. With an example involving a topped tree which came to be out control, the lecturer illustrated the following characteristics of topping: (1) It stimulates, rather than eliminates, the growth of leaves and branches, which betray the principle of good pruning that enable only a few strong branches to remain; (2) It increase the danger of disease and dead of branches, rather than remove diseased branches for the goodness of tree; (3) On heavy remove of mature leaves, the tree would be easy to starve, and thus run against the aim of pruning to enhance tree’s health; (4) It destroys the natural shape and beauty of the tree, while the purpose of good pruning is to enhance the natural shape and beauty; (5) Finally, it could not hold the tree within bounds as the reading stated, and actually in the example case the topped tree got wild and influenced the traffic. Simultaneously the lecturer has emphasized the importance of knowledge about pruning when looking after trees, for otherwise pruning like topping would cause more problems than it did solve. 因为点比较多,所以直接用了()加数字来列出观点,不知道是不是破坏游戏规则了..许多内容还是遗漏掉了 |
