Problems solved by technology

The deficiencies in the above methods are: 1. Only play a certain role in minimizing root damage, reducing water consumption, shortening root recovery time, etc. During this period of time, there is a problem with the balanced supply of water and nutrients, so the survival rate of transplanting is extremely low; 2. Although transplanting with soil balls can keep part of the intact root system, during the excavation process, 60-80% of the absorbed roots are destroyed. Cut off, in order to reduce the damage of the root system, the diameter of the soil ball is increased, but the overall weight is increased, which increases the difficulty of transportation and the cost of transplanting; Cut off 1 / 2-2 / 3 of the total amount, and it will take several years for the canopy to return to its original size, which cannot meet the requirements of urban greening ecological benefits and landscape benefits; 4. Shading and water spraying can only It plays a certain auxiliary role, but cannot fundamentally solve the water absorption problem of the tree body; 5. The management of fertilizer and water in the underground can only create conditions for root system recovery, but cannot solve the water supply during the period from planting to survival
[0003] The key to ensure the survival of tree transplantation is whether the supply of water and nutrients can be guaranteed from transplanting to before survival. Due to the serious damage of the root system, even if the soil moisture can be guaranteed to be saturated, the tree body cannot absorb sufficient water. , which is the root cause of the low survival rate of large trees transplanted, especially when planted with leaves in the growing season, a few hours of dehydration may cause permanent death

Embodiment 1

[0008] Transplanting broadleaf trees during dormancy.

[0009] A large broad-leaved tree with a diameter of 20 cm is transplanted from the field to a newly built park in the city. First, the large tree is dug out. When digging, a circle is drawn at a distance of 1.5 meters from the bottom of the trunk, and a width of 60-80 cm is dug vertically downward from the outside of the circle. While digging, cut off the dug roots with saws or scissors. The cut is flush with the saw. For thicker roots, cut off the extension appropriately. The soil near the rhizome does not need special protection. How much to bring, and then hoisted for transportation. Then dig a hole in advance, and trim the planting hole dug in advance according to the length and shape of the root system dug out on the original basis, so that the whole root system can be loosely placed in the planting hole. Then put the transported big tree into the planting pit, fill the pre-configured nutrient soil at the bottom and...

Embodiment 2

[0011] Transplant with leaves during growing season.

[0012]Both broad-leaved trees and conifers can be transplanted with leaves in the growing season, and the big trees are dug out and pitted in advance and planted and mixed with nutrient soil with embodiment 1. A large coniferous tree with a diameter of 25cm is transplanted from the field to a newly built park in the city in spring, and 4 holes are drilled at equal distances around the trunk at a height of 3 meters. The hole diameter is 10mm and the depth of the hole is 12cm. Insert the hollow bolts, and then connect the high-pressure water pipes, filters, water storage tanks, and pressure pumps in sequence. When loading the transport vehicle, start water injection. Water, the branches and leaves of the canopy are slightly trimmed to facilitate transportation. During transportation, the peripheral branches are properly bundled with soft ropes to prevent excessive damage to the branches and leaves. In order to make the water...

Embodiment 3

[0014] A Chinese pagoda tree has grown on the hillside for 500 years. The diameter of the tree is round, the largest diameter is 80cm, and the smallest diameter is 54cm. Excavation of large tree, digging a hole in advance, making culture soil are all with embodiment 1. When excavating and transporting, just drill holes and inject water. At a tree height of 3.5 meters, drill 10 holes equidistantly along the circumference of the tree. The hole depths are 15, 20, and 35 cm. Inject water once every 15 days, and stop water injection until spring germinates and survives as scheduled. The tree has survived for two years after planting.

Abstract

The big tree transplanting survival method includes digging out big tree, treating roots, digging hole in advance and planting. The present invention features that during the period from digging out to restoring the water absorbing root system, the trunk is bored and water is pressurized into inside the tree to balance the water content. The method has convenient conveyance and transplantation, low cost and high survival rate, is especially suitable for transplanting big tree with branches and leaves, and may be also used in curing ancient tree and famous tree.

Description

technical field [0001] The invention belongs to a method for transplanting trees, in particular to a method for transplanting and keeping large trees alive, which is suitable for transplanting large trees, ancient trees and precious trees. Background technique [0002] Trees play an important role in protecting the living environment of human beings and the ecological balance of the earth, especially in the current urban construction and road engineering construction. Trees, large trees, to maximize the ecological benefits of urban green spaces, and the landscape benefits of rare trees, ancient trees, and large trees, it is extremely important to study a successful method of transplanting large trees to keep them alive. Most of the transplanting refers to the transplanting of trees with a breast height and diameter of 15-20 cm or more. Old tree transplantation refers to the transplanting of trees over 100 years old. Since such trees have grown in situ f...
