Description

[Detailed Description of the Invention] <<Industrial Application Field>> The present invention provides a repair material for a ground, such as a golf course, in which a green belt is formed using green grass, and
The present invention relates to a method of forming a ground using this repair material.

<<Prior Art>> For example, at golf courses, the green grass is often stripped off by the club head during shots.

In such a case, the spot becomes a depression where the soil surface is exposed, called a dot, and if there are many dots scattered around the course, it may cause damage to the green area that was created at a great deal of expense. In addition to detracting from its aesthetic appearance, it was also difficult to hit the ball if it fell, and it was also uncomfortable to walk on.

In addition, there were many cases where the green grass was worn out and the soil surface was exposed.

For example, since the teeing ground is the starting point for play, the grass is often stripped or cut away by footsteps or club heads, leaving the soil exposed and unsightly.

In addition, the position of the pin was often moved on the green.

In this case, a new cup hole is drilled at the desired location on the green, and the cup hole that is no longer needed is drilled and filled with soil with grass to cover it. The soil surface was exposed in a circular shape between the grass and the buried soil, and these spots were scattered throughout the green, which had the disadvantage of greatly detracting from the beauty of the green itself.

The above-mentioned drawbacks were a serious problem because the aesthetics of this green are so important that the grass within the green is sometimes colored in order to always maintain a bright green color.

In addition, we aim to promote the growth of green grass, and
In order to deal with the grass that has grown, sand is spread several dozen times a year, and this is usually called top-filling sand, but since conventional top-filling sand has the same color as natural sand, In fact, it did not enhance the green tone of the green grass and instead spoiled its aesthetic appearance.

<<Problems to be Solved by the Invention>> As described above, this invention solves the drawbacks that occur when the green grass is torn off or worn out when the ground is formed using green grass. Providing effective repair materials to resolve problems in cooperation with the grass;
The present invention also aims to provide a method for forming a ground using this repair material.

≪Means for Solving the Problems≫ In order to solve the above-mentioned problems, the present invention involves coloring sand obtained by removing salt, plant seeds, mud, and other plants with a green coloring agent, and also by coloring sand obtained by removing plants such as salt, plant seeds, and mud. The present invention is characterized in that, in a ground having green grass such as that shown in FIG.

<<Description of Examples>> The details of the present invention will be described below with reference to Examples.

The green turf repair material according to this invention uses sand mined from the mountains and the sea, especially when used for natural turf.
After removing impurities such as salt, plant seeds, and mud that are harmful to the growth of turf, it is colored with green pigment or the like.

For its production, the green coloring agent ``Lone Green'' (trade name, manufactured by Sumitomo Chemical Co., Ltd.) is used.
Mix 600 c.c. with 3 parts of water to form a mixed aqueous liquid,
Pour each 200 kg of sand and stir and mix for about 5 minutes.

By stirring and mixing at such a ratio, green colored sand can be obtained without residual water.

Although the coloring production process is as described above, it is possible to obtain green sand of good quality, but the properties of the coloring agent used, the scale of mass production, and the cost of mass production, such as blowing hot air and spraying the sand while rotating, etc. The material to be colored is not limited to the sand mentioned above, but can be any material that can achieve the purpose of this invention. If so, it can be used as appropriate.

In addition, the constituent components of the green pigment described above include Nitroso Green, Visment Number, Visment Green, Visment Eight, a surfactant, and water. Of course, other colorants may be used as long as a repair material for use can be obtained.

Next, the color tone of this repair material changes slightly depending on the season, so if you color the sand to be almost the same color as the discolored grass, you will not only always have a constant green color, but also the green grass. We can provide sand with a coordinating shade depending on the tone of the sand.

In this case, the dilution rate of the green pigment may be changed as appropriate depending on the shade of coloring.

Furthermore, since the sand that is conventionally spread is often used for the growth of grass, in the repair material of the present invention, by mixing colored sand with fertilizer for grass, it is possible to simply modify the color and aesthetic appearance of the ground. However, it is also very effective for growing grass.

Next, a method of forming a ground using this repair material will be explained.

Example 1 What is shown in FIG. 1 is for a ground having green grass A, such as a course in a golf course, for example.
A dowel 1, which is a depression where the green grass A is dug up and the soil surface B is exposed, is buried with a repair agent 2 colored almost in the same color as the green grass A.

In this case, the repair agent 2... will remove the day bot 1.
Since the ball is buried, the ball does not fall into it, and it is also made easier to walk on.

Also, areas with different colors in the green belt (soil surface B)
It is possible to maintain the beauty of the course by cooperating with the surrounding green grass A.

Example 2 On a ground with green grass A in a golf course, green grass A was torn off or worn out and exposed from the soil surface B, such as the club head at the start of play, and the soil surface where the grass was damaged by foot stepping. As shown in Figures 2 to 4, green grass A is applied to the exposed teeing ground and cracks in grass A caused by the movement and formation of the pin cup hole 3 being dug out and buried with soil 4. Spray repair agent 2, which is colored almost the same color as ....

In addition, not only at golf courses but also at baseball stadiums, if soil gets mixed into the green grass area and the grass surface becomes dirty, by spraying the repair agent 2 of this invention, the green grass surface can be restored. The desired area can always be kept green, and the boundary line between green grass A and the adjacent soil surface B of other colors can be clearly distinguished.

Example 3 A green area such as a teeing ground formed by green grass A is formed using repair agent 2, which is colored almost the same color as green grass A, replacing the green grass A.

By doing this, it is possible to replace the areas where the grass is severely damaged with green grass A and form a green zone. This has the advantage of being able to be removed when unnecessary.

<<Effects>> As described above, the present invention relates to a repair material for green grass and a method of forming a ground using this repair material, and therefore has the following effects.

Effects of the first invention (1) Since the green grass repair material is made of green colored sand, the exposed soil surface can be buried or hidden in the same color as the grass, and it works in harmony with the green grass. It is possible to maintain the beauty of the lawn surface.

(2) Infrared absorption becomes stronger, promoting a rise in soil temperature, promoting the germination and growth of plants (green grass), and also exerting a frost-preventing effect.

Effects of the second invention (1) There is no need to spray or dye damaged areas of green grass with green paint as in the past, and a ground that can be easily repaired by simply spraying a repair agent can be created. can do.

(2) The ground surface can be made in the same color tone to match the color tone of the grass, which changes with the changing seasons.

(3) Also, because it is sand, it is very good for water drainage and walking.
