Problems solved by technology

[0006]1. Weak regeneration ability of cells and tissues: older trees, older stages of development, weak cell dedifferentiation ability, slow recovery of damaged root system during excavation and transplantation, and regeneration of new roots , new branch ability is weak
[0007]2. Poor absorption capacity of root system: During the long-term growth of big trees, the range of root system continues to expand, not only far beyond the extension range of the main branch, but also into the soil In the depths, most of the effective absorbing roots are outside the deep layer and the crown projection circle. When transplanting large trees, the range of rooting is much smaller than this range, generally only 7 to 10 times the diameter of the tree, and most of the main roots are within this range. And larger lateral roots, the root system is seriously lignified, and the absorption capacity is poor
[0008]3. Large transpiration of branches and leaves: Because of its luxuriant branches and leaves, large trees often have a large transpiration area. Dehydration, withering and death due to excessive water transpiration
In addition, strong sunlight, high temperature and drought in special years can also lead to the death of transplanted trees

Embodiment 1

[0035] Transplanted trees: Ginkgo, the age of the trees is 20-50 years, and the diameter of the trunk is 20-50 cm. The trees are native mountainous areas. The transplantation site is a park. The specific steps are:

[0036] (1) Root-cutting and crown-shrinking: Root-cutting will be carried out in situ during the dormant period of ginkgo 11 months in advance, and a 30-40cm wide and 50-70cm deep ring trench will be dug along 8-10 times the ground diameter of the trunk, and the thick lateral roots will use electricity. Saw to cut, smooth the cut, fill the ring trench with fertile soil and step on it, apply soil fungicides and rooting agents to promote the germination of new roots after filling the soil; after cutting the roots, cut off on the basis of maintaining the basic skeleton of the tree Excess branches, smooth the incision, smear the incision with wound smear;

[0037] (2) Excavation: Determine the diameter of the soil ball according to 6-10 times the diameter of the ginkgo tr...

Embodiment 2

[0048] Transplanting trees: Osmanthus, the age of the trees is 20-35 years, and the diameter of the trunk is 20-32 cm. The trees are native mountainous areas, and the transplant location is a park. The specific steps are:

[0049] (1) Cut the root and shrink the crown: cut the roots in situ during the slow growth period of the sweet-scented osmanthus 10 months in advance, dig a 30-40cm wide and 50-70cm deep ring trench along the trunk 8-10 times the ground diameter for thick lateral roots The chainsaw cuts, the cut is smooth, the ring trench is filled with fertile soil and stomped, and after the soil is filled, a soil fungicide and a rooting agent to promote the germination of new roots are applied; after the roots are cut, the tree is cut on the basis of maintaining the basic skeleton of the tree. Remove excess branches, make the incision smooth, and smear the incision with a wound smear;

[0050] (2) Excavation: Determine the diameter of the soil ball according to 6-10 times the...

Embodiment 3

[0061] Transplanting trees: Phoebe porcupines, the age of the trees is 18-20 years, the trunk diameter: 16-20cm, the trees are native mountain forests, and the transplantation locations are the green belts (mountains and planting soil) on both sides of the road. The specific steps are as follows:

[0062] (1) Cut the roots and shrink the crown: cut the roots 11 months in advance at the slow growth period of the prune, dig a 30-40cm wide and 50-70cm deep ring groove along the trunk 8-10 times the ground diameter, and thick lateral roots Use an electric saw to cut and make the cut smooth. Fill the ring trench with fertile soil and step on it. After filling the soil, apply a soil fungicide and a rooting agent to promote the germination of new roots; after cutting the roots, maintain the basic tree-shaped skeleton. Cut off the excess branches, make the incision smooth, and smear the incision with wound smear;

[0063] (2) Excavation: Determine the diameter of the earth ball for excavat...

Abstract

The invention provides a tree transplanting method. The tree transplanting method is used for processing the whole tree transplanting process to enable every step of the tree transplanting process to be provided with corresponding guaranteeing methods and measures, wherein the whole tree transplanting process comprises pre-transplanting pretreatment, digging, trimming, packaging, trunk wrapping, loading and transportation, planting, post-transplanting maintenance and the like. The tree transplanting method is particularly suitable for the tree transplanting for trees and rare plants, which have diameters at breast height above15-20cm. When the tree transplanting method is used, the survival rate of transplanted trees is greatly improved from 60-65% to 90-95%, so that the greatest effectiveness of the utilization of the limited resources is obtained.

Description

technical field [0001] The invention relates to a method for transplanting perennial woody plants, in particular to a method for transplanting large trees. technical background [0002] The big trees referred to mainly refer to those tree species that are tall or old and have a certain greening and ornamental value, with a trunk diameter of more than 10-15 cm, such as camphor, ginkgo, osmanthus, Zhennan, yellow jue tree, small Ye Rong et al. [0003] With the rapid development of urbanization, large tree transplantation is more and more widely used in various urban greening and landscape engineering constructions, especially some urban landscape projects, which require immediate greening effects in a short period of time and improve Ecological benefit of urban green land. However, there is a risk of survival in the transplantation of large trees. After transplantation of large trees in different places, there is often a large difference between the climate and soil of the...
