Abstract

[PROBLEMS] There is nothing to prevent damage caused by the drying of existing roots or the invasion of weeds, etc., so that expenses are increased.
Therefore, the present invention is to provide an effective weed invasion prevention plate that is light, easy to carry and easy to install, prevents damage to planted trees, increases work efficiency, and improves survival rate. Let it be an issue.
The present invention is based on a disk-shaped donut board made of existing natural plant fibers, the base is about 40 cm in diameter and the center is about 7 cm in diameter, from the upper end of the outer arc line of the base. A cut of about 2 cm in width is made in the center, and it is used so that it can be taken in and out of the root of the planted tree.

Description

  This invention relates to a weed invasion prevention plate for protecting roots and vines and weeds from entering around the roots covered with soil when planting tree seedlings in the mountains. It is.

Conventionally, when seedlings are planted in the mountains, the portion of the soil covered with roots at the time of planting is dried, and in order to prevent this, the ground cover removed by the planting hole is collected around the roots. It is covered. Under mowing work, the bushes, weeds, shrubs, vines, etc. that grew in the area of 3m wide in the ground work are trimmed from the ground with a mowing machine to prevent stuffiness due to the pressure of planted trees. ing.
In the case of planting in autumn, the first mowing is performed in the middle of June the next year and the second mowing is performed in the middle of August.
Undercutting twice a year continues for 3 years because the planted trees are small, and then continues once for 4 years. At the end of the lowering, most of the planted trees leave the vegetation and grow into vegetation. As a point of no longer being obstructed, 10 trimmings are standard in about 7 years.
Damage to planted trees is caused by drying of the roots immediately after planting, and then damage caused by dampness, weeds and vines caused by steaming and lack of sunlight, and small planting seedlings with weeds growing during mowing As a result, it is difficult to find a high percentage of damage caused by the mowing machine. As a result, if the target survival rate of the planted tree is not reached, supplementary planting is necessary, which increases costs. Is the current situation.
From this, it is light and easy to transport, can be installed easily, prevents root drying, reduces the number of undercutting, and further improves the work efficiency and improves the survival rate without cutting with the brush cutter. Something is desired.

Since there is nothing to prevent damage caused by root invasion or weed invasion, there is an increase in expenses.
Therefore, this device is light, easy to carry and easy to install, prevents damage to planted trees, improves work efficiency, improves survival rate and decomposes soil due to natural plant fiber, considering the environment It is an object to provide an effective prevention plate for weed intrusion.

  In order to solve the above problems, the invention is based on an existing natural plant fiber disk-shaped donut board, the base is about 40 cm in diameter and the center is 7 cm in diameter, and the outer arc of the base From the upper end of the line to the center, a cut of about 2 cm in width is made so that it can be inserted into and removed from the root of the planted tree.

The weed prevention board according to the present invention has a base part with a diameter of about 40 cm, a cut of about 2 cm from the end on the outer arc line of the base part toward the center part, and the root trunk of the seedling from the gap. 4 pieces of wooden mesh skewers near the center of the arc on the outer side of the base so that the weeds and other buds grow from the bottom of the donut plate. It is extremely effective in driving and fixing to prevent intrusion of folds and weeds around the cover soil.
In addition, it takes about 4-5 years for a donut board made of natural plant fiber to decompose into soil, and the number of undercutting during that period is 6 times a year for 3 years. Can be reduced to 3 times a year. In addition, since the planted tree is easy to find, the work efficiency is improved, the cutting by the brush cutter is eliminated, and the survival rate of the planted tree can be maintained at a high rate.
Natural plant fiber is an effective weed invasion prevention board because it decomposes the soil in about 4 to 5 years and is good for the environment.

An embodiment of the invention is shown in FIG.
The base 1 body of the weed invasion prevention board according to the present invention is a disc-like structure made of natural plant fibers and is a donut board structure. The size is about 40 cm in diameter, the thickness is about 0.9 cm, and the diameter of the central part 3 is about 6 cm. As a degree, it is the structure of the donut board which put the notch part 2 about 2 cm wide from the edge on the outer side arc line of the base 1 toward the center part 3. FIG.
The root trunk of the planted seedlings is installed at the center 3 through the gap between the cuts 2 so that the movement of the wind and the weeds do not rise even if the weeds and other buds grow under the weed invasion prevention plate. In addition, about four wooden mesh skewers are fixed to the inside of the outer arc line of the base portion 1 so as to prevent the intrusion of cocoons and weeds into the covered portion of the planted tree.
The material can also be used for corrugated cardboard such as plant plastic and wood bark.
The shape may be polygonal, and the size is classified into about 60 cm in diameter, about 40 cm in diameter, about 30 cm in diameter, and about 30 cm in diameter.

It is a perspective view which shows embodiment of the weed invasion prevention board which concerns on this invention.
