Description

[Detailed Description of the Invention] The present invention relates to a method for controlling and sterilizing harmful insects such as pine beetles on trees, including fruit trees (hereinafter referred to as trees), and for transplanting trees, etc. It is.

BACKGROUND ART To control harmful insects and harmful bacteria on trees, etc., a method is generally used in which chemicals are sprayed over the entire tree using a sprayer. This method is not very effective against harmful insects and bacteria that have infiltrated the inside of the tree, and it is time-consuming to spray. In particular, the impact of sprayed chemicals on the human body and the environment is serious.

Instead of spraying the chemicals all over trees, etc., there is a method of spraying or injecting the chemicals into the soil and absorbing them through the roots of the trees, etc., but like the above-mentioned method, the problem of environmental pollution occurs.

In addition, a method for controlling pine beetles has been developed in which one or more holes are drilled into the tree trunk and a chemical solution is injected into the tree trunk, but the holes remain in the tree trunk, which significantly reduces the commercial value of the wood and also reduces its resistance to wind. It weakens.

Therefore, the present invention has been developed by attaching a liquid supply bag to the cut roots of trees, etc., and supplying chemical solutions, water, etc. stored in the tank to the liquid supply bag, so that the roots can be directly extracted from the cut roots. It absorbs chemical solutions, water, etc., and aims to eliminate the drawbacks of conventional methods.

Hereinafter, this invention will be explained in detail based on Examples.

First, a liquid supply bag for supplying a liquid such as a medicinal solution to a cut root to be used in carrying out this invention is prepared.
This will be explained based on FIG.

Reference numeral 1 denotes a liquid supply bag, which is made of synthetic rubber or natural rubber that is highly elastic, corrosion resistant, and chemical resistant. In particular, the material is natural or synthetic rubber latex.
This liquid supply bag 1 has a circular cross section and a "pot" shape, the upper part is formed with a smaller diameter than the lower part, and the bottom part has a
A hose connection port 2 for connecting a liquid supply hose via a joint 2' is provided, and a tube connection port 3 for inserting an air vent tube is protruded from the lower side.

In addition, the lower part of the liquid supply bag is formed thickly,
In particular, a reinforcing ring 1' is provided on the outer periphery of the boundary with the hose connection port 2, so that the liquid supply bag is crushed by earth pressure, and the liquid supply bag is crushed from between the hose connection port 2 and the joint 2'. It is designed to prevent fluid leakage.

Furthermore, although not shown, inside the upper part of the liquid supply bag 1. By providing three ring-shaped protrusions (watering holes), it is possible to completely prevent liquid leakage from between the roots and the liquid supply bag.

The size of the liquid supply bag 1 varies depending on the size of the tree, etc., and therefore the thickness of the root to be cut.

An example of controlling pine beetles using the above-mentioned liquid supply bag will be described.

As shown in FIG. 2, first, the root of the target tree T is dug down and one or more branch roots 5 next to the force root 4 are cut. Here, power roots refer to roots that serve as a base that is especially necessary for the growth of trees, and the number of branches and roots 5 to be cut is one if the diameter of the target tree is 10 cm or less as per the eye, and one if the diameter is 10 cm or more and 30 cm or more. In the following cases, 3 pieces, 30cm
In the above cases, the standard is 4 or more.

A liquid supply bag 1 whose upper inner diameter is smaller than the outer diameter of the branch root is fitted into the cut branch root 5 from the opening, and the third
As shown in the figure, fix it watertight using a fastener 6 or a string. When inserting the cut branch root, be careful not to block the hose connection port 2 and tube connection port 3.

Then, the end of the liquid supply hose 7 is connected to the hose connection port 2 via the joint 2'. The tip of the liquid supply hose 7 is connected to a tank 8 suspended from a branch of the target tree T, but if multiple liquid supply bags are required,
Use an appropriate joint such as Y-type joint 9.

The tank 8 contains aqueous insecticides such as acephate hydration powders, which are agricultural chemicals for controlling pine beetles, and Cartap aqueous solvents, or oil-based insecticides such as organic phosphorous liquids. For example, an acephate hydrating agent (trade name Ortolan hydrating agent) containing 50% acephate, the main ingredients of which are carbamoylthio, N・N-
Dimethylamino, Cartap aqueous solvent (trade name Padan aqueous solution) containing 50% Cartap is diluted to 25 c.c. per 100 c.c. of water, usually at a ratio of about 4 c.c. to 10 c.c. do.

Further, the end of a transparent air vent tube 10 is inserted into the tube connection port 3, and the tip of the air vent tube is fixed to a stake 11 driven into the ground. Note that the tip of the air vent tube is connected to tank 8.
Keep the water level higher than the water level of the chemical solution stored inside.

Finally, open the cap 8' of the tank 8 to start supplying the liquid, and after confirming that the chemical solution is being supplied into the liquid supply bag 1 using the air vent tube 10 (if the air vent tube is transparent) (This makes it easy to check the water level), inspect each part, and bury the roots back in.

In this way, the chemical solution in the solution bag is absorbed from the cut roots and distributed throughout the target tree. According to experiments, it takes 3 to 4 days for the medicinal solution to permeate to the leaf tips, so the period for absorbing the medicinal solution is 1.
More than a week.

As explained above, if this invention is implemented,
There is no problem of environmental pollution, and unlike the method of making a hole in the tree trunk and injecting a chemical solution, this method does not damage the commercial value of the tree or weaken its resistance to wind.

Note that this invention is not limited to controlling pine beetles, but can also be implemented to control other harmful insects and harmful bacteria by selecting an appropriate chemical solution, and can also be implemented to absorb hormones and liquid fertilizers. .

Next, an embodiment in which the present invention is utilized for transplanting trees and the like will be described.

Traditionally, transplanting of trees and the like has been carried out as follows.

First, around the trunk, dig around 3.3 times the diameter of the tree to be transplanted, for example, if the diameter of the trunk is about 30cm, dig up an area of about 100cm to cover the local soil. To the extent that it is possible to transport the roots with the roots still attached, use rough ropes, etc. to pack the roots into a spherical root ball and transport. At the transplant site, a root ball is buried in the hole that is dug, and then the soil is filled.

With this type of transplanting method, even the fine roots are cut during digging, making it impossible to absorb water, and even if the branches and leaves are removed, the tree tends to weaken, resulting in a poor survival rate.

For this reason, various hormonal agents have been developed, but there is no specific medicine that is better than water, and extreme care must be taken in water management after transplantation. However, the mortality rate is high due to lack of water, especially in the summer, and root rot is also common due to overwatering.

In contrast to the conventional method, the present invention is implemented as follows.

The digging work required for transplanting and the packing of the root ball are the same as before, but before constructing the root ball, one power root (for small trees for bonsai) must be placed in the vertical center of the root area. For garden trees, select three power roots and cut them leaving about 6 cm of excess outside of the intended root ball. At the same time as cutting the power roots, attach a rehydration bag filled with water to each power root and tie it with a string to secure it. This water supply bag is made of linen cloth coated with vinyl chloride, and must not be removed until it is replaced with the fluid supply bag.

As shown in Figure 4, at the transplant site, completely bury the root ball 12 with the water replenishment bag attached to a depth of about 10 cm beneath the root root to make the next work easier. root ball 1
2, the above-mentioned liquid supply bag 1 is attached to the power root instead of the water supply bag. Connecting the liquid supply bag to the tank 8 via the liquid supply hose 7 and connecting the air vent tube 10 is the same as in the previous embodiment. If there are a plurality of power roots cut, the liquid supply hose 7 is branched using a joint, and each liquid supply bag is connected to the tank.

When the above work is completed, start water supply, confirm that water is being supplied to the liquid supply bag 1 through the air vent tube 10, and after checking each part, cover the root ball with soil and continue to do so for 4 hours. You only need to supply water for a month or five months.

In addition, when transplanting a large number of trees, etc., 1
Water is supplied from each tank to the liquid supply bag using a joint.

As mentioned above, after transplantation, the transplanted tree can absorb water from its cut roots as needed, so the survival rate is extremely high.
