Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing a turf mat, and more particularly to a method for producing a turf mat by cutting grown turf to obtain a turf mat.

[0002]

2. Description of the Related Art A turf mat used when covering bare ground with turf is usually formed into a mat by peeling grass cultivated in a field with a lawn stripping machine. In this case, since the surface part of the upland is usually formed of a fertile soil layer, the obtained turf mat has a bottom layer composed of a fertile soil layer.

On the other hand, in golf courses and the like, greens are produced by growing grass on sand. This is because if the green soil is composed of a sand layer, the water handling will be good and a good shot feeling will be obtained. In such a green, grass can be pasted by sticking the above-mentioned grass mat on the green sand layer. But,
In this case, the fertile soil layer and the green sand layer forming the turf mat are hard to fit in with each other, and pathogenic bacteria are easily generated in the soil layer. In addition, when used on a golf course, black soil is exposed and the appearance is likely to be impaired.

Therefore, a grass mat having a sand layer as a bottom layer is used for pasting grass. As a method of obtaining such a grass mat, a method of forming a sand layer on the surface of a field, growing grass on the sand layer, and cutting the obtained grass to obtain a grass mat is adopted. In this turf mat manufacturing method, it is necessary to form a thick sand layer, and a great amount of labor is required to form the sand layer. Further, when the growth of grass and the cutting of the grass mat are repeated, the number of rotten roots remaining in the sand layer increases, and the sand layer needs to be replaced. A great deal of labor is required for this replacement work. Therefore, the manufacturing cost of the grass mat for sand is inevitably high.

An object of the present invention is to produce a grass mat for sand at a low cost.

[0006]

The method for producing a turf mat according to the present invention includes the following steps. (1) A sand layer forming step of forming a sand layer on a sheet that is affixed to the ground surface and formed with drainage holes (2) A grass growing step of growing grass on the sand layer (3) Obtained in the grass growing step Grass mat making process to cut grass to obtain grass mat

[0007]

In the method for producing a turf mat according to the present invention, first, a sand layer is formed on a sheet which is attached to the ground surface and has drain holes. This gives a sand layer for forming the bottom layer of the turf mat. Next, grass is grown on the sand layer, and the grown grass is cut to obtain a grass mat.

Here, since the sand layer is formed on the sheet, it suffices to form a thin sand layer, and the labor required for the sand layer formation and replacement work is reduced. Therefore, the grass mat for sand can be manufactured at low cost.

EXAMPLE FIG. 1 shows an example of a turf mat obtained by the method for producing a turf mat according to the present invention. This turf mat 1 is a sheet of bent turf and is cultivated short for green. The turf mat 1 is mainly composed of a turf layer 2 and a sand layer 3. The cutting height of the turf layer 2 is 4 to 10 mm.
And the cutting height of a typical turf sheet (about 14 mm)
It is lower than. Sand layer 3 has a layer thickness of 10 mm
The grass roots are intricately entangled inside.

Next, with reference to FIG. 2, an example of the method for producing a turf mat according to the present invention will be described. First, a vinyl sheet 5 is pasted on the soil layer 4 in the field (A). The vinyl sheet 5 is an agricultural resin sheet made of polyethylene or the like. The color of the sheet 5 may be any color including black and transparent.

Next, by repeating the work of pushing the bar member 6 out of the vinyl sheet 5, the holes 5a are formed in the sheet 5 and the holes 4a are formed in the soil layer 4 (B). Bar 6
Is a round bar having a diameter of about 20 to 30 mm, and is made of, for example, iron. The formed holes 5a and 4a are for draining water. The holes 5a are provided in the vinyl sheet 5 so that, for example, about 6 to 9 holes per 1 m ² are arranged at substantially equal intervals. When forming the holes 5a, the sheet portion around the holes enters the holes 4a of the soil layer 4 so that the sheet 5 can be fixed to the soil layer 4.

Next, a sand layer 3 having a predetermined thickness is formed on the vinyl sheet 5 (C). The sand layer 3 is formed to have a thickness of about 10 mm and a thickness as uniform as possible. At this time, a part of the sand is filled in the hole 4a through the hole 5a. When the formation of the sand layer 3 is completed, seeds of grass (not shown) are sown on the surface of the sand layer 3 to grow grass with watering and fertilizer supply (D). Here the grass roots 7 extend into the sand layer 3,
A part of it penetrates into the holes 4a and also absorbs nutrients from the soil layer 4. The surplus of rainwater or sprinkling water permeates the soil layer 4 through the holes 5a of the vinyl sheet 5. Further, the vinyl sheet 5 can prevent weeds and pests from entering the sand layer 3 from the soil layer 4. Furthermore, the grass roots 7 that have entered the soil layer 4 through the holes 5a act as a locking portion, and the movement of the sand layer 3 due to rainfall or the like can be prevented.

After growing grass for more than one year, width 25-40c
The grass is peeled off into a mat shape having a length of m and a length of 150 to 300 cm (E). Here, the grass is cut into a grid shape so as to have a predetermined mat size. At this time, the sheet 5 is also cut at the same time. When the cutting work is finished, the cut grass mat 1
And, the end of the vinyl sheet 5 is grasped and rolled up. At this time, the grass mat 1 and the vinyl sheet 5 are peeled off from the surface of the soil layer 4 while cutting off the root 7 extending from the hole 5a with a cutter 8 or the like. Since only a part of the grass roots 7 grown in the sand layer 3 extends to the soil layer 4, it is easy to cut off the roots 7, and the grass mat 1 and the vinyl sheet 5 are removed from the soil layer 4. It can be easily torn off. Therefore, there is no need to perform root cutting work using a lawn stripper. In addition, since the number of grass roots 7 cut in the grass stripping operation is small and most of the roots 7 are maintained in a healthy state, the grass management after the grass sticking operation can be easily performed.

The turf mat 1 which has been peeled off is wound in a roll shape as shown in FIG. 3 after the vinyl sheet 5 is removed, and is tied with a string 10 so that it can be handled as a set of two sheets. Done. As described above, in this embodiment, since the sand layer 3 is formed on the vinyl sheet 5, it is sufficient to form the thin sand layer 3, and the labor required for forming and replacing the sand layer 3 is reduced. Therefore, the grass mat 1 for sand at low cost
Can be manufactured.

[Other Embodiments] (a) Instead of the bent grass, the grass mat 1 may be configured by using Koryo grass or other kinds of grass. (B) The present invention may be carried out using a vinyl sheet 5 in which the holes 5a are formed in advance. In this case, the hole forming work using the rod 6 can be omitted. (C) The present invention can be carried out in the same manner even if the soil layer 4 is sandy.

[0016]

In the method for producing a turf mat according to the present invention, since the sand layer is formed on the sheet, it is sufficient to form the thin sand layer, and the labor required for the sand layer formation and the replacement work is reduced. Therefore, the grass mat for sand can be manufactured at low cost.
