大樹移植與撫育管理新世紀的城市是生態健全、環境優美、人與自然和諧共存的城市。城市園林化是衡量城市現代化文明程度的重要標志，是提升城市品位，滿足人民群眾物質文化生活水平的需要。大樹移植與撫育管理，已經成為園林城市綠化、美化不可缺少的手段和措施。大樹移植可以迅速達到綠化、美化的園林效果，也是保護在城市改建擴建工程中，已成林的古樹和各種樹木的有效手段。大樹移植中的大樹是指喬木、亞喬木，胸徑10厘米以上的樹木。從大樹移植樹木來源可分為人工培育大樹移植木和天然生長大樹移植木兩類。人工培育的移植木是經過各種技術措施培育的樹木，移植后的樹木能夠適應各種生態環境，成活率較高。天然生長的移植木大部分生長在大森林生態環境中，移植后不適應小氣候生態環境，成活率較低。從事大樹移植多年的實踐中觀察到，不論人工、天然生長的大樹移植木，只要遵循自然生長規律進行移植，就可以收到較好的成活效果。一、大樹移植的主要技術措施1．移植木的選擇。從植物生理學分析，無論人工、天然樹木每棵樹木的生長都有方向性，在同一個立地條件下，陽坡的樹冠大于陰坡；陽坡的側根短于陰坡；陽坡的葉片大于陰坡；陽坡的結實多于陰坡。故移植前必須用鉛油，在朝陽向方位的胸徑部位劃一個記號。大樹移植木最好選擇在交通便利、林分郁閉度小的立地或孤樹，平地立地比斜坡立地生長的移植木好。在移植木直徑相同的條件下，樹矮的比樹高的移植木好。樹種選擇上樹葉小的比樹葉大的好，針葉樹比闊葉樹好，軟闊葉樹比硬闊葉樹成活率高。2．移植時間。最好選擇在樹木休眠期，春季萌動前和秋季樹木落葉后為最佳時間。在城市改建擴建工程中的大樹移植，可以在生長旺季(夏季)移植，最好選擇在連陰天或降雨前后移植。3．移植木掘苗。挖掘移植木一般距根部中心120厘米左右，沿規定的根幅外圈垂直向下挖。挖掘過程中，遇粗根時用手鋸鋸斷，以免根部劈裂，當側根全部挖斷后，將樹身推倒并切斷主根，盡量不傷根皮和須根，保留原土。最后用濕草袋和草繩包扎后待運輸。4．移植木修剪。修剪主要是減少樹木水分蒸發、便于運輸和栽植。如果有影響運輸的側枝可適當剪短，原則上針葉樹不修剪，闊葉樹可適當修剪。5．移植木栽植。栽植時要保持樹木直立，方位正確(如方向錯位樹木緩苗期延長7天左右，成活率低20%左右)，分層埋土踏實，移植木要設立支撐，防止根部搖動透氣影響成活。二、移植木的撫育管理大樹移植后應當立即澆水，保持土壤濕潤，加強管護，注意病蟲害的發生。1．平衡株勢。為緩解移植木根與冠之間的矛盾，把地面上的枝葉相應修減，使植株根冠比維持必要的平衡關系。2．強度修剪。為避免主干上因修剪造成過多、過大的傷面，去除主干大枝時可留高樁。粗的著生部位好的要高，細的著生部位欠佳的要低。3．澆水遮蔭。生長旺季溫度高，蒸騰量大，除定植時灌足飽水外，還要經常給移植木灑水和根部灌水。4．加強管護。移植后設立支架、防護欄，防治病蟲害，剪除多余的萌生條，適時灌水、施肥、除草、松土。（來源：黑龍江林業2003年第1期）
