《云南林业》1985年第五期刘锐章同志发表的《怎样给树木修枝打杈》一文,谈到对针阔叶树的修枝时,文章认为:“从加速切口愈合,消除无节和培养无节材的角度来说,最好贴近树干修枝,这叫平切。它适合于大多数针阔叶树种,但要求技术较高。”对这一问题,我有点不同的看法。我们河北省对于树木的修枝,在群众中流传着这样一条林业谚语“杨树要平,松柏留钉”。这就是说,不同树种有不同的修枝打杈方法,不能一概而论。例如,杨树等速生阔叶树种,愈合能力强,修枝时要用锋利的工具,紧贴树干削平,不留枝茬,以免形成死节或在茬口腐烂成洞,积存雨水,引起树干腐朽、罹病。而对于松柏等针叶树木,由于生长缓慢,愈合能力差,修枝时若进行“平切”,不留枝茬,边修成平滑的茬口,势必造成茬口过大,不能很快愈合,就容易招致病虫
When talking about pruning of coniferous and broad-leaved trees, the article entitled “From Accelerating Incision Heal, Eliminating Nodules and Having No Nodules It is best to stick to the trunk pruning, which is flat cut, it is suitable for most coniferous and broad-leaved trees, but requires higher technology. ”I’m a bit different on this issue. We in Hebei Province for the pruning of trees, among the masses circulating such a forestry proverb “poplar to be flat, pine and cypress nails.” This means that different tree species have different methods of pruning, which can not be generalized. For example, poplar and other fast-growing broad-leaved species, healing ability, pruning should use sharp tools, close to the trunk flattened, leaving no stubble, so as to avoid the formation of dead ends or stubble holes in the stubble rot, accumulated rain, causing trunk decay, Illness. Conifer and other conifers and other trees, due to slow growth, poor healing ability, if the pruning “flat cut”, leaving no stubble, while repairing a smooth stubble, will inevitably cause stubble is too large, can not heal quickly, it is easy to incur Pests
