近年来,随着国家六大生态建设工程的全面实施,平原地区速生杨树的种植面积迅速扩大,以中林46、欧美107、欧美108等为代表的优质速生杨,以其速生性和良好的加工性能越来越受到群众的普遍重视。速生杨已成为平原林业生产的当家树种。但是笔者调查中发现,不少地方在杨树修枝管理中存在着一些不容忽视的问题,严重影响了杨树的生长量和木材品质,应引起高度重视。一是过量修枝问题,部分干部群众缺乏科学的修枝知识,认为树木越修枝越往高处长,把树木修成一个小脑袋;还有的单位和个人,把修枝作业承包给收购薪材枝杈的单位和个人,作业时只顾剪取树权而不管树木生长,造成过重修枝。修枝过重,减少了幼树枝叶量,直接影响树木的正常生长。二是修枝不规范。不少群众修枝时不用修枝剪,而用铁锹铲掉或用铁钩硬扒,造成枝干劈裂并留有参差不齐的桩柱,既影响了树木的生长又严重降低了木材品质。 In recent years, with the full implementation of the six national ecological construction projects, the planting area of ​​fast-growing poplar in the plain has rapidly expanded. With high-quality poplar represented by Zhonglin 46, Europe and the United States 107, Europe and the United States 108, with its fast-growing and good The processing performance is getting more and more attention by the masses. Fast growing poplar has become the original tree species of forestry production in the plain. However, the author found that in many areas there are some problems that can not be ignored in the pruning of poplar and seriously affect the growth of poplar and the quality of the wood, which should be given high priority. First, excessive pruning problems, some cadres and the masses lack scientific knowledge of pruning, that the more branches pruning trees to the top, the trees into a small head; there are units and individuals, the pruning operation to the acquisition salary The branches and individuals of timber twigs, when they are doing their homework, only care about cutting the trees for their own rights, regardless of the growth of the trees, resulting in excessive pruning. Pruning too heavy, reducing the amount of young leaves, a direct impact on the normal growth of trees. The second is non-standard pruning. Many people do not prune pruning shears, shovel shovel or hook with a hard grilled, resulting in the splitting of the branches and leaving uneven piles, both affect the growth of trees and seriously reduce the quality of wood .
