绿化树和材质树的修枝方法树木修枝是造林绿化扶育管理措施之一。通过修枝人为的“助、减、缓”等技术措施调节、控制通风与透光，给树木生长发育创造适宜条件，造就通直干形、冠形优美的优质材质。修枝应根据林种与树种的不同、造林密度与造林目的差异而采取不同的方法。针叶树种造林时，可修掉残枝、死枝、多头枝，只保留一个直立枝。造林后5“15年修掉过密的枝条，修去侧枝1-2轮，每隔4—5年修一次。杨树用于营造防护林与用材林，应及时选留主干上的中心枝作为领导枝，将其竞争枝及时除掉，摘、指侧芽，修掉多余的侧枝，促进高、粗的生长。城乡四旁绿化与城市绿化小区树木的修枝要讲究树型美观大方，别具一格，适宜观赏。对于已截顶的柳树，应有目的培养成“四面斗”或“三股撑”形，避免有两个主干的“料杈”形。修剪切口要光滑，严防壁裂。茬高以1厘米—2厘米为宜。过高过低都会影响创面愈合和树木的生长。修剪季节以早春或晚秋和冬季为宜。早春以树液流动前为宜。如树木发芽时修剪，树体水分蒸腾快，失水，消耗养分多，不利于树木生长。有的速生树种，如杨、柳等也可以夏季修枝。但是，注意不要在阴雨天修枝，以免伤口浸水，感染病害。修枝要注意“冬剪枝，夏控侧”。即冬季实行强树重剪，弱树轻剪，重点把直立强壮的竞争枝从基部修掉。夏季实行强旺枝重控，控强留弱，把树势调整均衡，掌握强侧打头，壮枝重剪，弱枝轻剪、小枝多留的原则，以达到突出主干，促进树木加快生长的修剪目的。———摘自《黑龙江林业》2002.4
