大树移植与抚育管理新世纪的城市是生态健全、环境优美、人与自然和谐共存的城市。城市园林化是衡量城市现代化文明程度的重要标志，是提升城市品位，满足人民群众物质文化生活水平的需要。大树移植与抚育管理，已经成为园林城市绿化、美化不可缺少的手段和措施。大树移植可以迅速达到绿化、美化的园林效果，也是保护在城市改建扩建工程中，已成林的古树和各种树木的有效手段。大树移植中的大树是指乔木、亚乔木，胸径10厘米以上的树木。从大树移植树木来源可分为人工培育大树移植木和天然生长大树移植木两类。人工培育的移植木是经过各种技术措施培育的树木，移植后的树木能够适应各种生态环境，成活率较高。天然生长的移植木大部分生长在大森林生态环境中，移植后不适应小气候生态环境，成活率较低。从事大树移植多年的实践中观察到，不论人工、天然生长的大树移植木，只要遵循自然生长规律进行移植，就可以收到较好的成活效果。一、大树移植的主要技术措施1．移植木的选择。从植物生理学分析，无论人工、天然树木每棵树木的生长都有方向性，在同一个立地条件下，阳坡的树冠大于阴坡；阳坡的侧根短于阴坡；阳坡的叶片大于阴坡；阳坡的结实多于阴坡。故移植前必须用铅油，在朝阳向方位的胸径部位划一个记号。大树移植木最好选择在交通便利、林分郁闭度小的立地或孤树，平地立地比斜坡立地生长的移植木好。在移植木直径相同的条件下，树矮的比树高的移植木好。树种选择上树叶小的比树叶大的好，针叶树比阔叶树好，软阔叶树比硬阔叶树成活率高。2．移植时间。最好选择在树木休眠期，春季萌动前和秋季树木落叶后为最佳时间。在城市改建扩建工程中的大树移植，可以在生长旺季(夏季)移植，最好选择在连阴天或降雨前后移植。3．移植木掘苗。挖掘移植木一般距根部中心120厘米左右，沿规定的根幅外圈垂直向下挖。挖掘过程中，遇粗根时用手锯锯断，以免根部劈裂，当侧根全部挖断后，将树身推倒并切断主根，尽量不伤根皮和须根，保留原土。最后用湿草袋和草绳包扎后待运输。4．移植木修剪。修剪主要是减少树木水分蒸发、便于运输和栽植。如果有影响运输的侧枝可适当剪短，原则上针叶树不修剪，阔叶树可适当修剪。5．移植木栽植。栽植时要保持树木直立，方位正确(如方向错位树木缓苗期延长7天左右，成活率低20%左右)，分层埋土踏实，移植木要设立支撑，防止根部摇动透气影响成活。二、移植木的抚育管理大树移植后应当立即浇水，保持土壤湿润，加强管护，注意病虫害的发生。1．平衡株势。为缓解移植木根与冠之间的矛盾，把地面上的枝叶相应修减，使植株根冠比维持必要的平衡关系。2．强度修剪。为避免主干上因修剪造成过多、过大的伤面，去除主干大枝时可留高桩。粗的着生部位好的要高，细的着生部位欠佳的要低。3．浇水遮荫。生长旺季温度高，蒸腾量大，除定植时灌足饱水外，还要经常给移植木洒水和根部灌水。4．加强管护。移植后设立支架、防护栏，防治病虫害，剪除多余的萌生条，适时灌水、施肥、除草、松土。（来源：黑龙江林业2003年第1期）
