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 was transplanted from the wild to a newly built park in the city. First, the large tree was dug out. When digging, a circle was drawn at a distance of 1.5 meters from the bottom of the trunk, and the width was 60-80 cm vertically downward from the outside of the circle. Cut off the dug roots with a saw or scissors while digging. The cut and the saw cut are flush. The thicker roots should be cut off appropriately. The soil close to the rhizomes does not need to be specially protected. How many to carry, then hoist and transport. Dig the hole in advance, and trim the planting hole dug in advance according to the length and shape of the root system, so that the entire root system can be loosely placed in the planting hole. Then put the transported big tree into the planting pit, fill in the pre-configured nutrient soil at the bottom and around the root system, compact t...

Embodiment 2

[0011] Transplant with leaves during the growing season.

[0012] Both broad-leaved trees and coniferous trees can be transplanted with leaves in the growing season. The excavation and digging of large trees in advance and the planting and nutrient soil are the same as in Example 1. A large coniferous tree with a diameter of 25cm is transplanted from the wild to a newly built park in the city in spring. 4 holes are equally spaced around the trunk at a height of 3 meters. The hole diameter is 10mm and the hole depth is 12cm. Insert the hollow bolts, and then connect the high-pressure water pipes, filters, water storage tanks, and pressure pumps in sequence. When the transport truck is installed, start water injection, and the water injection pressure is 0.4Mpa to prevent transitional loss in the tree body after root breaking and transportation. Water, the branches and leaves of the canopy should be slightly trimmed to facilitate transportation. During transportation, the outer bra...

Embodiment 3

[0014] A Chinese locust tree has been growing on the hillside for 500 years. The diameter of the tree is off-round, with a maximum diameter of 80cm and a minimum diameter of 54cm. It is an ancient tree that is mainly protected and transplanted for highway construction. The excavation of the big tree, the digging of the hole in advance, and the preparation of the cultivation soil are all the same as in Example 1. When excavated and transported, punch holes and inject water. At the height of 3.5 meters, punch 10 holes equally spaced along the tree circumference. The hole depths are 15, 20, and 35cm. The holes are arranged at intervals. The water injection pressure is 0.6Mpa. Inject water once every 15 days until the spring sprouts and survive as scheduled, stop water injection. The tree has survived for two years after being planted.

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 keeping alive large trees, which is suitable for transplanting large trees, ancient trees and precious trees. Background technique [0002] Trees play a major 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, in order to speed up urban greening, optimize the plant configuration and spatial structure of urban green spaces, and protect ancient Trees, big trees, to maximize the ecological benefits of urban green space, as well as the landscape benefits of valuable trees, old trees, and big trees, it is extremely important to study a successful method of transplanting big trees to keep alive. Most transplantation refers to the transplantation of trees with a breast height of 15-20cm or more. Ancient tree transplantation refers to the transplantati...
