Problems solved by technology

[0004] When repairing the tree hole, because the shape of the tree hole is unique and ornamental, the tree hole is usually kept instead of being filled. In this case, repairing the tree hole usually requires cleaning and disinfecting the rotten surface of the tree hole. By improving the shape of the tree hole to facilitate drainage and reduce the accumulation of water to soak and rot again, but although the rainwater is drained, the tree hole is always in a dark environment. The surface of the hole is again rotting due to long-term humidity, which affects tree growth, so there is room for improvement

Embodiment 1

[0055] A protective layer composition, the preparation method of the protective layer composition protects the following steps:

[0056] a. Grinding, as follows:

[0057] Add polyacrylonitrile, polyphthalamide and hydroxyethyl cellulose into a grinder and grind them into powders with a particle size of 10-100 nm.

[0058] b. Mixing, as follows:

[0059] Add 20kg of paraffin wax to the stirred tank and heat it to 70°C. After the paraffin wax is completely melted, add 100kg of polypropylene particles, 15kg of polyacrylonitrile powder, 12kg of polyphthalamide powder and 3kg of hydroxyethyl cellulose powder at a speed of 45r. / min, stirring for 10min to form a premix.

[0060] c. Extrusion granulation, as follows:

[0061] The premix was discharged into a twin-screw extruder, heated to 150° C., extruded into underwater granulation and granulated to form a protective layer composition.

Embodiment 2

[0063] A protective layer composition, the preparation method of the protective layer composition protects the following steps:

[0064] a. Grinding, as follows:

Abstract

The invention relates to the technical field of ancient tree rejuvenation and provides a tree hole repair method for rejuvenation of ancient trees to solve the re-rot problem after tree hole repair. According to the technical scheme, the method includes the following steps of S1, polishing, S2, disinfection, S3, spray-coating of a tree hole protective layer and S4, polishing, wherein the tree hole protective layer is formed by curing a protective layer composition, and the protective layer composition comprises, by mass, 100 parts of polypropylene, 15-20 parts of polyacrylonitrile, 12-18 parts of polyphthalamide, 3-5 parts of hydroxyethyl cellulose and 20-30 parts of paraffin. Through spray-coating of the tree hole protective layer, the inner walls of tree holes can be protected through the protective layer after disinfection, and the inner walls of the tree holes are not easily eroded by water and thus not easy to rot.

Description

technical field [0001] The invention relates to the technical field of rejuvenation of old trees, in particular to a tree hole restoration construction method for rejuvenation of old trees. Background technique [0002] Ancient and famous trees are not only a kind of precious natural resources, but also a living historical relic, but in a long growth cycle, most of them have suffered different degrees of man-made and natural damage, and it is necessary to rejuvenate ancient and famous trees. . [0003] Generally, old tree rejuvenation includes soil improvement, tree hole repair, tree damage treatment, tree reinforcement, etc. [0004] When repairing the tree hole, because the shape of the tree hole is unique and ornamental, the tree hole is usually kept instead of being filled. In this case, repairing the tree hole usually requires cleaning and disinfecting the rotten surface of the tree hole. By improving the shape of the tree hole to facilitate drainage and reduce the ac...
