A method of explanting old trees and rejuvenating them

Abstract

The invention discloses a method for movement and rejuvenation of old trees and belongs to the field of transplantation of old trees and big trees. The method comprises the steps that 1, the old treesare subjected to mathematical modeling; 2, the crowns of the old trees are pruned; 3, according to a mathematical modeling result, lump digging contour lines are marked on the surrounding ground where the trunks are located, lump digging operation is conducted along the outer edges of the lump digging contour lines, root breaking grooves are dug accordingly, and cylindrical soil lumps are formed;4, the cylindrical soil lumps are subjected to root pruning operation, and apple-shaped soil lumps are formed; 5, beams are transversely inserted in the bottoms of the apple-shaped soil lumps in thehorizontal direction and connected to form a first base; 6, a second base is assembled on a carrying plate of a semitrailer; 7, hoisting equipment is used for hoisting the first base, the big trees are lifted accordingly, and the first base is moved to the carrying plate of the semitrailer; 8, the old trees are lain down, and the apple-shaped soil lumps are placed on the second base; 9, the old trees are transported to planting points for unloading, loading and planting.

Description

technical field [0001] The invention relates to the technical field of transplanting old trees and big trees, in particular to a method for relocating and rejuvenating old trees. Background technique [0002] Most of the existing large tree transplanting technology objects are deciduous trees with a trunk diameter of more than 20 cm and evergreen species of more than 15 cm under the age of 100 years; A set of scientific and mature technology is often to copy the technology of transplanting ordinary large trees to transplanting old trees. Compared with "young" trees less than 100 years old, the metabolic level of old trees is relatively low, so the conventional transplanting of large trees is adopted. Tree Techniques Transplanting old trees can greatly reduce transplant survival. [0003] The big tree transplanting method of prior art is: the first step, search the historical record of big tree, grasp the data such as tree age, living habit, climatic condition; Changes in o...

AI Technical Summary

Problems solved by technology

Among them, the requirement for the excavation size of the soil lump only refers to the diameter of the trunk, that is, 5 to 8 times the diameter of the trunk is the only basis for excavating the size of the soil lump, and the accuracy is poor

[0006] 2. The amount of absorbing roots (mainly capillary roots) in the transplanting technique will directly affect the survival rate and rejuvenation quality and speed of seedlings after transplanting old trees, especially the absorbing roots around the soil lump and the technology of promoting new roots after root breaking It will be an important guarantee for the success rate of transplantation. In the prior art, the absorption root treatment of large trees is relatively extensive, which greatly reduces the survival rate of trees.

[0007] 3. In the process of transporting large trees in the existing transplanting technology, there will be direct use of ropes to wrap the trunk, and then the large tree will be transported to the transport vehicle through a crane. damage to the facility, while the ropes can also damage the bark, affecting arbor graft survival and overall appearance

[0008] 4. The existing technology is relatively backward in the technical management after replanting of large trees, which also affects the resurrection and growth of trees

[0009] 5. The pruning technology for the crown of the existing technology is relatively backward, which is very easy to cause damage to the branches, and at the same time, too many broken branches will be accumulated in the crown, which greatly delays the speed of crown pruning

[0011] The above-mentioned patent documents mainly improve the survival rate of transplanted trees by improving the quality of the soil to improve the root system revival and growth. The embarrassment of having backward means
