T/CZBXBZ 038-2025 Technical specification for tree protective transplanting

Scope

This document defines the terms and definitions of protective tree relocation, and stipulates the pre-relocation preparation, relocation, transportation, planting, maintenance, and archival management for protective tree relocation. This document applies to large tree relocation. Other types of protective relocation, such as for precious trees or ancient and famous trees or backup resources, can be referenced for implementation. 5.3 Relocation Principles The principle of "digging, wrapping, transporting, and planting immediately" should be followed to minimize the transplantation period and reduce the exposure time of the roots. During the operation, attention should be paid to keeping the roots moist, protecting them from sunlight and frost. 5.4 Pre-Relocation Process 5.4.1 Pruning should be carried out more than half a year before relocation. For vigorous or precious large trees, pruning should be carried out 6 months to 2 years before relocation. If necessary, pruning can be carried out in stages. The pruning scope should be within about 10 cm of the predetermined diameter of the root ball, and the depth should be determined according to the main absorption root layer. 5.4.2 The pruning cuts should be smooth, and insecticides and fungicides should be immediately sprayed and rooting agents should be watered. Backfilling soil should be selected from loose and fertile soil, and it should be compacted layer by layer and thoroughly watered. 5.4.3 The trees should be uniformly numbered and oriented (marking the north-south direction of the original habitat) to facilitate subsequent construction and planting. 5.4.4 Safety barriers and warning signs should be set up at the construction site to ensure safety during operation. 5.5 Pre-Relocation Pruning 5.5.1 Pruning should be carried out reasonably according to the difficulty of tree survival, the relocation season, and the characteristics of the crown to balance the tree's vitality. a) Deciduous tr
