Description

[Detailed Description of the Invention] Technical Field: The present invention relates to a container for injecting a chemical solution into a tree trunk.

Prior Art: In order to eliminate or kill pests in trees, it has been conventional practice to spray liquid insecticides on trees or into the soil around the roots of trees. In such conventional methods, the insecticide is washed away by rain, making it impossible to obtain a sufficient insecticidal effect. In addition, there is a risk that the washed away pesticides may contaminate well water or tap water sources, causing environmental pollution. As an improvement method, it has been proposed to make a hole at an appropriate location in the tree trunk and insert the tip of a chemical solution injection container into the hole to inject the chemical solution into the tree trunk. However, according to this method, in trees that secrete a relatively large amount of resin liquid, such as pine trees, the resin liquid flows from the tip of the inserted chemical liquid injection container and closes the chemical liquid injection port. Therefore, injection of drug solutions becomes impossible during periods of high biological activity. Biological activity flourishes throughout the year.
In tropical regions, it is impossible to inject chemicals using this method. Additionally, if air remains in the hole provided in the tree trunk, absorption of the chemical solution into the tree trunk will be impaired. Depending on the type of resin liquid, it solidifies when it comes into contact with residual air, resulting in significantly poor absorption of the chemical liquid.

Purpose of the invention: The purpose of the invention is to provide a chemical solution injection container that can inject a chemical solution into a tree trunk regardless of the season or region. Another object of the present invention is to provide a chemical solution storage container that allows resin liquid to flow into the chemical liquid container and utilizes the inflow pressure at that time to increase injection efficiency of the chemical liquid. Still another object of the present invention is to provide a chemical liquid injection container that can effectively absorb chemical liquid into trees.

Summary of the invention: The drug solution injection container of the present invention includes a drug solution storage section, a conduit whose one end communicates with the storage section and whose other end opens to the outside, and a stopper attached around the conduit in a liquid-tight manner. and the conduit partially or entirely constitutes a shoulder at a suitable distance from the open end thereof, and has at least one through hole in the shoulder, whereby the above object is achieved. be done.

Examples: The present invention will be described in detail below based on examples and with reference to the drawings.

As shown in FIG. 1, the container 1 of the present invention includes a drug solution storage section 11 that stores a drug solution 10, and a conduit 2. One end of the conduit 2 is connected to the chemical solution storage section 11, and the other end is open to the outside. At appropriate locations on the conduit 2, plugs 3 are fitted around the conduit 2 in a liquid-tight manner. The stopper 3 is, for example, a cylindrical or conical cup, with one end open and the other end integrally fixed to the conduit 2.

As shown in FIGS. 2a or 2b, the conduit 2 partially or entirely constitutes a shoulder 21 at an appropriate distance along its axial direction from its open end 210. This shoulder portion 21 is provided with at least one through hole 20, and this hole 20 is formed in the drug solution storage portion 1.
It is connected to 1. Conduit opening end 210 and shoulder 21
The distance from the hole to the tree trunk is appropriately selected depending on the capacity and shape of the hole to be drilled in the tree trunk.

The chemical solution 10 includes an insecticide, an antimicrobial agent,
This includes chemicals that are preferably administered directly to the tree trunk, such as fertilizers, nutrients, and plant hormones. Examples include insecticides such as lannate, dicistone, and teracure P; and antimicrobial agents such as captan, gliodin, benlate, thiobendazole, amical, biocide, kasugamycin, griseofulvin, and polyoxin. This is used in the form of a solution, emulsion or suspension.

A chemical solution is injected into a tree trunk using the container 1 of the present invention as follows: First, a hole is made diagonally downward in the tree trunk with a drill. The diameter of the hole is desirably selected so that the stopper 3 provided on the conduit 2 of the container 1 fits therein in a liquid-tight manner. The container 1 is inserted into this hole as shown in FIG.
The conduit 2 is attached so that the through hole 20 provided in the shoulder 21 is positioned upward.

The drug solution 10 in the container 1 is injected into the hole 40 through the conduit 2. This injected chemical solution is absorbed through the vascular bundles of the tree 4. The air in the hole 40 flows into the container 1 from the through hole 20 as the chemical solution 10 is injected. The chemical solution 10 is injected into the tree while displacing air. On the other hand, the resin liquid 12 gradually flows out from the resin path into the hole 40. Since the resin liquid 12 has a lighter specific gravity than the chemical liquid, it accumulates in the upper layer inside the hole 40. The resin liquid 12 accumulated in the hole flows into the chemical liquid storage part 11 through the through hole 20 of the conduit shoulder 21. Resin liquid 1
2 floats above the chemical liquid in the chemical liquid storage section 11. In this way, even if the resin liquid accumulates in the hole 40 of the tree trunk 4 and further flows into the container 1, the resin liquid and the chemical liquid flow into the conduit 2 and the chemical liquid storage part 11 as if each liquid were mixed due to the difference in specific gravity between the resin liquid and the chemical liquid. Since the flow paths flow as if they were formed separately, the injection of the chemical solution into the tree trunk 4 is not hindered in any way.

Effects of the invention: The container of the present invention is configured to contain the chemical solution in a manner that replaces the air and resin liquid in the tree trunk hole, so the injection of the chemical solution is not hindered by air or resin liquid. do not have. Rather, the injection of the chemical liquid can be performed more smoothly and efficiently due to the inflow pressure of air and resin liquid. Since no air remains in the tree trunk hole, absorption of the chemical solution into the tree is improved. This container also has the function of removing the resin liquid from the tree trunk hole, so it can be used regardless of the season or region, and can also exhibit excellent functionality even in seasons when biological activity is rather active.
