Big tree transplanting survival method

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...

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
