pruning intensity修枝強度

綠化樹和材質樹的修枝方法樹木修枝是造林綠化扶育管理措施之一。通過修枝人為的“助、減、緩”等技術措施調節、控制通風與透光，給樹木生長發育創造適宜條件，造就通直干形、冠形優美的優質材質。修枝應根據林種與樹種的不同、造林密度與造林目的差異而采取不同的方法。針葉樹種造林時，可修掉殘枝、死枝、多頭枝，只保留一個直立枝。造林后5“15年修掉過密的枝條，修去側枝1-2輪，每隔4—5年修一次。楊樹用于營造防護林與用材林，應及時選留主干上的中心枝作為領導枝，將其競爭枝及時除掉，摘、指側芽，修掉多余的側枝，促進高、粗的生長。城鄉四旁綠化與城市綠化小區樹木的修枝要講究樹型美觀大方，別具一格，適宜觀賞。對于已截頂的柳樹，應有目的培養成“四面斗”或“三股撐”形，避免有兩個主干的“料杈”形。修剪切口要光滑，嚴防壁裂。茬高以1厘米—2厘米為宜。過高過低都會影響創面愈合和樹木的生長。修剪季節以早春或晚秋和冬季為宜。早春以樹液流動前為宜。如樹木發芽時修剪，樹體水分蒸騰快，失水，消耗養分多，不利于樹木生長。有的速生樹種，如楊、柳等也可以夏季修枝。但是，注意不要在陰雨天修枝，以免傷口浸水，感染病害。修枝要注意“冬剪枝，夏控側”。即冬季實行強樹重剪，弱樹輕剪，重點把直立強壯的競爭枝從基部修掉。夏季實行強旺枝重控，控強留弱，把樹勢調整均衡，掌握強側打頭，壯枝重剪，弱枝輕剪、小枝多留的原則，以達到突出主干，促進樹木加快生長的修剪目的。———摘自《黑龍江林業》2002.4
