城市树木移植成活的机理与技术研究

Study on Survival Mechanisms and Technologies for Tree Transplantation in Urban

针对目前城市树木移植中因缺少系统性的技术指导,造成部分移植树木成活率低与生长态势差的现状,结合近几年城市树木移植工程的实践经验,分析了城市树木移植成活机理,阐述了树木移植中应遵循的近似生境和树势平衡两大基本原理以及季节适时和断根缩坨两大基本条件,着重介绍了树木移植在挖掘、包扎、起吊、定植等诸环节中应掌握的技术要领与新技术新方法的采用以及移植后在水肥管理、遮荫防寒、病虫害防治、跟踪观察等养护管理措施,期望能为同行提供有效借鉴。

To the conditions of some trees transplanted with low survival rate and bad growth for the lack of technical advice in urban, the survival mechanism of tree transplantation was analyzed, and two basic principles of approximate habitat and balanced tree vigor, two basic conditions of proper time and root pruning and ball clay reduction which must be carried out in transplanting were introduced. Moreover, the technical essentials and new techniques and methods adopted in the process of digging, wrapping, lifting and fix planting for tree transplanting, and the maintenance measures where were water and fertilizer management, shading and cold proof, pest control and prevention, tracing observation were emphasized. All of those were combined with the experiences summarization derived from the engineering practices of tree transplantation in urban, and would be beneficial to others.
