About the need to transplant dry diameter is less than 15 cm and transplanting survival of the trees, if normal time of transplanting with soil ball, can be increased without stop. On stem diameter greater than 20 cm tall trees, especially famous types, transplanting of former disposal is very necessary. I.e. before transplanting 2 3 a spring or autumn, centered on the trunk, to 6 8 times of the diameter at breast height diameter of a circle, in the first round of relatively two Duan Dong arc and arc (north or south of arc and arc) dig out 30 40 cm wide, deep 50-70 cm (detailed depth depends on the depth of the tree roots) of the annular groove and the following in the same way to dig the other two directions of annular groove. 沟挖毕，回填肥土并分层夯实，然后浇透水。这样，第3a沟内长满须根，即可起大树了，应急时，等1次断根后数月即可移栽。修剪的目的是显而易见的，主要是为了坚持树木公开、地上两局部代谢均衡。修剪强度要详细状况详细剖析，树冠愈大，根部愈裸，伤根愈多，生根愈难;时节愈反，愈应加大修剪强度，尽可能减小树冠的蒸腾面积。修剪后剪口可用塑料薄膜、凡士林、石蜡或植物专用伤口涂补剂包封。Ditch dug, backfill soil fertilizer and hierarchical compaction, and then pour water. So, 3 a ditch full of fibrous root, can be a big tree, emergency, such as increased 1 months after transplanting. Pruning is the purpose of the obvious, mainly in order to adhere to the open, the two trees local metabolic balance. Pruning intensity to a detailed situation analysis in detail, the greater the crown of a tree, the roots of the naked and the more root damage, take root and harder; Season the reverse, more should intensify the pruning intensity, reduce the canopy transpiration area as much as possible. After pruning shears used plastic film, vaseline, paraffin or plant dedicated wound coated adhesive coating. 关于裸根移栽的大树，还应对根部做必要的整理，重点剪除断根、烂根、枯根，短截无细根的主根。挖树和包装，目前普遍采用人工发掘软材包装移栽法大型玩具，适用于发掘圆形土球和胸径为1015cm的常绿乔木，用蒲包、草片或用塑编资料加草绳包装(树干用浸湿的草绳缠绕至分枝点)。此外还有木箱包装移栽法，适用于发掘方形土台和胸径1525cm的常绿乔木。About bare-root transplanting big trees and roots to do the necessary arrangement to cope with the situation, increased focus on cut off, roots rotted, dry root, short section without the taproot of fine root. Dig tree and packaging, is currently widely used artificial excavated soft wood packaging transplanting method, suitable for circular soil ball and diameter at breast height of 10 15 cm of evergreen trees, with the calceolarias, grass or packed in plastic woven materials plus straw rope (point) with wet straw rope winding to branch. In addition to wooden case packing transplanting method, is suitable for square TuTai and 15 25 cm diameter at breast height of evergreen trees. 大树移栽时，一定要尽可能加大土球，普通可按树木胸径68倍发掘圆形土球或方形土台停止包装，以尽可能多地保存根系，起树前要把干基四周23m以内的碎石、瓦砾、灌木丛等肃清洁净，对大树还应准备3根支柱停止支撑太阳能热水工程，以防倒伏后形成工伤事故和损坏树木。Big tree transplanting, must as far as possible to increase soil ball, common according to tree diameter at breast height 6 8 times round soil ball or square TuTai stop packing, in order to save as much as possible the root, the tree before within 2 3 m, the area around the stem base of debris, rubble, bushes, etc. Clean up clean, the tree also 3 pillars should be prepared to stop, to prevent lodging forms after inductrial injury accident and the damage to trees. 普通的大树移栽都采用吊车装卸、汽车运输的方法。但关于间隔较近、数量不大的树木，可用吊车直接吊移。树木装进汽车时，要使树冠朝向汽车尾部，根部靠近驾驶室锅炉辅机。树干包上柔软资料放在木架上，用软绳扎紧，树冠也要用软绳恰当缠拢。Common tree transplanting all adopt the method of crane loading and unloading, motor transport. But not about the close interval, number of trees, move directly to the crane crane is available. When trees into a car, to make the crown toward the car tail, roots near the bridge. Soft material on the gallows tree package, with soft rope tied tightly, canopy with soft rope properly wrapped properly. 大树移栽系一项难度较大的园林绿化工程技术，其难易水平常因树种、年龄、时节、间隔、地点等的不同而异。因而，移栽前必需停止精心筹划并制定完好配套的移栽计划，确保大树移栽胜利。移栽中的技术措施，移栽时期，大树移栽最好选择在树木休眠期停止，普通以春季萌动前和秋季落叶后为最佳。合理选择移栽时期，对有效降低大树移栽本钱很有裨益。Big tree transplanting is a difficult landscape engineering technology, it is difficult to xiao for ordinary tree species, age, season, spacing, location, etc. Therefore, transplanting must stop before the carefully planned and intact the transplanting of form a complete set plan, ensure that big tree transplanting. Transplanting the technical measures, transplanting time, big tree
