The technology of in-situ protection and rejuvenation of famous trees and old trees by trunk root promotion

Abstract

The invention discloses a technology of promoting growth of roots from tree trunks and in situ protecting and rejuvenating famous and ancient trees. The technology includes the following steps: firstly, peeling the cork layer of the tree trunks; then, mixing a water-retaining agent with rooting powder to obtain a mixture and coating the tree trunks with the mixture; finally, backfilling soil; retaining water and keeping normal field management. After 2-3 months, the buried tree trunk sections quickly grow roots in an explosive manner, so that root mass regeneration is achieved. The technology provided by the invention aims at the problems of the existing measures for protecting the famous and ancient trees, and adopts scientific and technical means to preserve the tree crowns completely, enable the famous and ancient trees with dead roots and withered leaves to be gradually luxuriant and vibrant, and prevent the trees from declining and dying, and the trees can be refreshed and rejuvenated effectively. The technology is simple to operate, little in investment and small in risk, does not destroy the landscape, and can promote the ancient trees to grow roots from the tree trunks, so that an enormous root system can be established in the plough layer of the soil surface, and root regeneration is realized.

Description

technical field [0001] The invention relates to the technical field of forestry, in particular to a technology for in situ protection and rejuvenation of famous and ancient trees through trunk root promotion. Background technique [0002] Famous trees and ancient trees are the witness of a local history and culture, and they are living textbooks. At present, due to the needs of drainage and flood control in the process of urbanization, it has become a common phenomenon to raise the ground level. This has caused a large part of the trunk of many large trees to be preserved in situ to be submerged below the surface, and the root system is buried deep underground, and the root system breathes. The effect is inhibited, gradually suffocated and dies, the tree grows weak because the root system cannot provide effective nutrient supply, the leaves become yellow, necrotic spots appear on the leaves, photosynthesis cannot be carried out normally, and the nutritional status of the tre...

Problems solved by technology

However, since the main capillary roots of the big tree are far away from the main trunk, it is difficult to have a good effect, and a large pit is left on the ground, which is neither beautiful nor safe.

Another protective measure is to adopt a plan of digging big soil balls to lift and transplant, but this is expensive. Because the root system of the digging tree is seriously damaged, the branches of the tree need to be retracted significantly to reduce the amount of branches and leaves to ensure survival.
