Discussion on ancient trees and big trees transplanting in urban garden

The introduction of big trees into Shanghai, is an effective way to promote the process of greening process and improve the environment quality.

Mature technical managements were probed during transplanting the evergreen big trees and defoliated bare root trees to provide guidance for the increase of surviving rate and standardization of the maintenance of transplanted big trees.

More labors,mechanical equipment and money are needed for big tree transplantation,and big trees renewable capacity is much weaker than saplings and seedlings and consequently they are hard to survive.

Based on the successful experience of the replanting of potted plant trees in Tianyi square,this paper discusses about the method of the replanting way of big trees in different conditions,thus pointing out its application in similar projects.

The survival rate of transplanting old or big trees lies in the transplanting technology of big trees,which includes heeling in and transplanting.
