A method of whitening tree trunks

Abstract

The invention belongs to the field of tree maintenance and particularly relates to a trunk whitewashing method. The method comprises the following steps that a roller type hairbrush is used for smearing a trunk with a layer of zinc sulfate water solution with the mass concentration of 8%, then the roller type hairbrush is dipped in white pigment containing titanium dioxide, and the trunk is whitewashed. The roller type hairbrush comprises a handle and a roller set, the handle is composed of a handle body and a fixing rod, the fixing rod is connected with one end of the roller set or a fixing board, the roller set is formed by connecting five roller brushes in series, a bearing is arranged in the center of each roller brush, the roller brushes are installed on a steel wire bent to be arc in a rolling mode through the bearings, one ends of all layers of roller sets are fixed on the fixing board, the other ends of all layers of roller sets are fixedly connected through a wire; the spacing between the roller sets is 1 cm, and the roller type hairbrush saves a large amount of labor and a large number of materials. The white pigment containing the titanium dioxide is high in adhesive force, is good in burning prevention capacity, and has the sterilization, insect prevention and warmth keeping effects.

Description

technical field [0001] The invention belongs to the field of tree maintenance, and in particular relates to a method for whitening tree trunks. Background technique [0002] Whitening the trunk can prevent pests and diseases, delay tree germination and avoid sunburn damage. In areas with large sunshine and temperature changes, whitewashing can reduce the absorption of solar radiant heat by the aboveground part of the tree, reflect sunlight, and avoid local increase in the humidity of the trunk. [0003] When using traditional brushes to smear, it takes a lot of manpower and time, and it is easy to cause uneven smearing and waste of whitening agent. With the development of science and technology, a large number of mechanized whitening devices have appeared, but these devices only It is not practical to use for specific areas and whitening agents. In the prior art, the whitening agent is mostly used after raw materials such as quicklime water are prepared, and it is easy to c...

Problems solved by technology

[0003] When using traditional brushes to smear, it takes a lot of manpower and time, and it is easy to cause uneven smearing and waste of whitening agent. With the development of science and technology, a large number of mechanized whitening devices have appeared, but these devices only It is used for specific areas and whitening agents, and the actual operability is not good

In the prior art, the whitening agent is mostly used after raw materials such as quicklime water are prepared, and it is easy to cause peeling off in dry or rainy and snowy weather, and the durability is not strong, and too much quicklime will easily cause corrosion of the trunk, and too little will cause corrosion. The whiteness is not enough, and the anti-burning strength is poor. In order to improve the durability, polyvinyl alcohol and other binders are added to the existing whitening agent. The product is used in autumn and winter, when the temperature is low, it needs to be applied quickly
