Description

Ancient tree rejuvenation method

Technical Field

The invention relates to the technical field of ancient tree rejuvenation, in particular to an ancient tree rejuvenation method.

Background

Ancient trees grow in one place for hundreds of years and even thousands of years, the soil has limited fertilizer content, and the ancient trees often show the symptoms of lack of fertilizer; in addition, the artificial treading is hard, the ventilation is poor, the drainage is also poor, and the root system growth is extremely unfavorable. At present, there are many methods for rejuvenating ancient trees, but the method for rejuvenating the ancient trees by abutment is very few, and the effect is good.

Firstly, the ancient trees have poor self-vitality and slow metabolism, and are difficult to accept rejuvenation measures with large traumas; old root of ancient tree is many, and really can accomplish and absorb this process and need rely on the root hair to accomplish, nevertheless ancient tree is because old, and the root system is huge, and the root hair is kept away from the trunk, and the transport distance is far away, and in addition the transportation difficulty that self metabolism is slow.

Second, the treatment of the symptoms is not the root cause. Rejuvenation means, such as fertilization, soil improvement and the like, have a temporary effect as the effect is worse and worse with the passage of time. Some physical strapping support techniques work in the opposite direction if not properly done.

Disclosure of Invention

The present invention has been made to solve the above problems, and an object of the present invention is to provide a method for rejuvenating an ancient tree, which can add a long-term power to the ancient tree from the nutritional status and physiological status of the ancient tree itself, and can prevent the ancient tree from falling down due to the influence of an external force.

The technical scheme adopted by the invention for solving the technical problems is as follows:

an ancient tree rejuvenation method comprises the following steps of tree root inarching and tree hole repairing:

a, selecting tree species which are the same as or mutually exclusive with ancient trees as scions;

and B, grafting the scion to the ancient tree.

Further, in the step A, the scion is 2-5 years old and has a diameter of about 5-10 cm to grow seedlings, and a grafting inclined plane with the angle of 75 degrees and the diameter of 15-20 cm is cut on the stock scion.

Further, in the step B, before grafting, the ancient trees are simply ditched to reduce the stains.

Further, in the step B, a section of the ancient tree root of 15-20 cm is selected as an abutting part, and the abutting part is cut into V-shaped broken bark to expose a cambium.

Further, in step B, the scion is sufficiently combined with the opening, fixed with iron nails, and bundled with a bundling band.

Further, in the step B, after grafting, after healing and survival, cutting off redundant parts, removing the strapping tape and pulling out the iron nail.

Further, in the step B, a crevasse is manufactured at the tree hole or the sunken defect part, rotten tissues at the damaged part of the crevasse are removed, the crevasse is subjected to disinfection and antiseptic treatment, and the core material part is filled and sealed;

making a primary joint surface of the stock on a cambium of the sapwood at the bottom of the crevasse and cleaning the joint surface;

making a joint surface on the scion, and enabling the joint surface of the scion to be matched with the joint surface of the stock;

jointing the jointing surface of the scion and the primary jointing surface of the stock, wrapping the jointing surface with the simulated bark, binding the exterior of the simulated bark with a rope, and maintaining, thereby completing the primary rejuvenation type repair of the tree hole or the sunken defect part of the ancient tree;

and after the first rejuvenation type restoration is carried out for one year, removing the simulated barks bound outside the binding surface, and carrying out second rejuvenation type restoration on the ancient tree lacerations.

Further, the second rejuvenation type repair comprises the following specific steps;

a, making a secondary junction surface of a stock at a sapwood cambium part above a cut of an ancient tree, making a secondary junction surface of a scion at a part close to the secondary junction surface of the stock above the same scion, and enabling the secondary junction surface of the stock to be matched with the secondary junction surface of the scion;

b, cleaning the joint surface and mutually jointing the secondary joint surface of one or more scions with the secondary joint surface of the stock.

The invention has the beneficial effects that:

1. the invention increases the active roots and the number of root hairs by a inarching method, strengthens the absorption capacity of the ancient tree heels, improves the metabolism speed of new and old trees, and improves the self nutritional conditions of the tree bodies from the roots, thereby improving the vitality of the ancient trees, improving the life quality and prolonging the life.

2. In the invention, a section of the ancient tree root of 15-20 cm is selected as an abutting part, and the abutting part is cut into V-shaped broken bark to expose a cambium. According to the diameter of the ancient tree and the self condition, 2 to 8 cuts can be selected, and the principle of keeping as uniform as possible and avoiding weak parts is followed. A plurality of small wound surfaces are adopted for abutting joint, the number of the wound surfaces can be controlled, the possibility of infection is reduced, and the phenomenon that the ancient trees are too weak to bear accelerated death is avoided.

Detailed Description

and B, grafting the scion to the ancient tree.

In the step A, the scion is 2-5 years old and grows seedlings with the diameter of about 5-10 cm, the seedlings grow vigorously and have developed root systems, the roots of the seedlings are reserved, the root hairs are protected to be cut off from the root by about one meter, lateral buds are cleaned, 75-degree and 15-20 cm approach grafting inclined planes are cut on the scion of the stock, the cambium is fully exposed, and the two surfaces are flat and smooth by a quick cutter and cannot be repeatedly scraped by the cutter.

And in the step B, before grafting, simply ditching and reducing stains for the ancient trees, and cleaning the surrounding environment of the ancient trees.

And in the step B, selecting a section of the old tree root of 15-20 cm as an abutting part, and cutting a V-shaped skin at the abutting part to expose a cambium. According to the diameter of the ancient tree and the self condition, 2 to 8 cuts can be selected, and the principle of keeping as uniform as possible and avoiding weak parts is followed. A plurality of small wound surfaces are adopted for abutting joint, the number of the wound surfaces can be controlled, the possibility of infection is reduced, and the phenomenon that the ancient trees are too weak to bear accelerated death is avoided.

And step B, fully combining the scions with the openings, fixing the scions by using iron nails, bundling the scions by using a bundling belt, paying attention to sterilization and disinfection, preventing infection, enabling the moisture generated by the growth of wood layers of the trees to permeate into each other and the barks to grow continuously, and utilizing the nature of the trees to enable the roots to permeate into the liquid of the trunks, namely circulate, and enable the barks to grow into a whole.
