Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a vegetation lawn sheet for vegetation of lawns.

[0002]

2. Description of the Related Art Conventionally, when turf is planted on a predetermined site,
The method of directly vegetating turf on a predetermined site, transplanting turf vegetated in the field, or producing a turf sheet rooted in a mat or net in the field and transferring this turf sheet to a predetermined site for deployment is there. In recent years, methods based on productivity and simplicity of construction are becoming common. Many mats or nets used in this method have a mesh shape or similar in order to ensure air permeability and water permeability,
Generally, a method of sandwiching the grass roots and fixing them on a mat or a net (for example, JP-A-2-104216 and JP-A-3-164111) is adopted.

The applicant has focused on the convenience of turf sheets,
With the aim of streamlining productivity and streamlining vegetation work,
In No. 4-241710, we proposed a lawn tensioning method using a lawn sheet in which lawn roots are entangled in a sheet. This is because the grass roots of densely turf are intricately intricately involved, the grass roots are entwined with a net in the field, the vegetated grass sheet is rolled and shipped, and it is deployed at a predetermined site.

[0004]

[Problems to be Solved by the Invention] In the previously proposed construction method, in order to repeat the production of turf sheets in the field, after each shipment, a new turf is unwound and sprinkled on a newly laid net or mat. Therefore, this point has been an obstacle to improving the production efficiency. Further, it has been difficult to change the shipping time or widely change the form of the turf sheet according to the customer's request.

Therefore, the first priority is to make efficient use of fields.
We examined it in order to enable the production of turf sheets to be put on a commercial basis by changing the shipping time and the aspect of the turf sheets according to customer needs.

[0006]

[Means for Solving the Problems] As a result, the developed turf sheet for vegetation spreads the net 4 on the cultivated field 1 and then spreads the unraveled turf 2 to sprinkle the soil 3 and the turf root 21 Grow the grass 2 until it gets entangled in the net 4, then cut the roots,
Produced. It is also possible to sprinkle the turf 2 that has been unraveled on the cultivated field 1 to spread the net 4 and then spread the soil 3 on it.

It is also possible to develop the net 4 in the field 1 in which the grass 5 has been planted, grow the grass 5 until the grass roots 51 are entangled with the net 4, and then cut the roots for production. In this case as well, the net 4 may be expanded to the cultivated field 1 and then the vegetated grass 5 may be expanded.

As described above, as a result of root cutting, grass roots remain in the field. In this case, the field 1 where the lawn remains
Expand the net 4 and put the soil 3 on the net 4,
The turf sheet can be repeatedly produced by growing the turf until the turf is entangled with the net 4 and then cutting the turf. In this method, the net 4 may be expanded to the field 1 after growing the remaining grass roots up to the grass.

The vegetation grass sheet thus produced is composed of a plurality of nets having functions such as water permeability, air permeability, degradability or water retention, or a net 44 having one or several of the above functions. Entwined with the grass 41, 43, 46 having turf carried by entanglement with, turfing artificial turf 42, processing such as molding of a predetermined shape through the front surface or the back surface or from the front surface to the back surface It may be one that supports grass by doing so.

Specific materials and shapes of the net referred to in the present invention include all net-like planar materials. For example, in addition to a mesh woven fabric made of natural materials such as cotton, wool, and hemp, a mesh woven fabric or a mesh-shaped non-woven fabric made of metal or synthetic resin, a felt-shaped mat, or the like is also included in the net herein. In addition, the net has a simple net shape and has a single function, a plurality of nets having a single function, a single net having a plurality of functions, a coarsely flocked artificial grass, etc. And processing and decoration are free.

[0011]

The production method used for obtaining the grass sheet for vegetation of the present invention is as follows: a net 4 is developed on or under the newly grown grass 2 or a net 4 is formed on or under the grass 5 already vegetated. By deploying, the net 4 and the turf roots 21 and 51 are entangled with each other to enable the production of turf sheets integrated with the net 4. As a result, the turf 2, 5 does not disperse even if the adhered soil (grain soil attached to the net) is completely removed from the turf sheet.

Further, according to this production method, even if the nets 4 spread on the turf 2, 5 are entangled with the turf roots 21, 51, the turf sheet can be produced. Deploy Net 4 from above to the Shibakane 21, 51 of
A new grass sheet can be produced by growing grass from the grass roots 21 and 51. The same applies when the nets 4 are deployed after the grass roots 21 and 51 have been grown on the grass. Thereby, the productivity of the grass sheet in the same field can be improved.

On the other hand, the grass sheet that can be produced by this production method is a net 41,43,4 having a shape capable of entwining the grass roots.
If it is 4,46, its functionality, processing, and decoration can be freely set, so that a turf sheet having a wide range of characteristics can be obtained. For example, a turf sheet that can be stored for a long period of time can be made by using a net with excellent water retention, or a turf sheet that can be settled at the transplanted site early after transplanting can be made by using a net that is degradable by microorganisms. .

EXAMPLES Examples of vegetation grass sheet production method and grass sheet according to the present invention will be described below with reference to the drawings. FIG. 1 is a partially cutaway perspective view of a first embodiment showing a produced turf sheet, and FIGS. 2 to 4 are sectional views showing the production procedure of the first embodiment at each stage. Is a state in which a net is developed in the field and turf and soil are laid, Fig. 3 is a state in which turf grows and entangles turf in the net, and Fig. 4 is a state in which the turf is cut and the turf sheet is shipped in a roll state. Represents In addition, this 1st Example sprinkles the turf which was unfolded on the net 4 which spread | deployed in the cultivated field 1, and produced it by covering the soil 3.

The field 1 seen in FIGS. 1 and 2 has a width of 1.2.
The soil 6 cultivated in a 100 m ² area with a length of 84 m and a length of about 20 cm was cultivated by rolling the soil 6 with tire rollers (not shown). The net 4 is a mesh fabric made of polypropylene and made of degradable plastic.
Woven into a 16 mm square mesh, the same width as in field 1.
It is cut to a length of 1.2 m and a length of about 84 m.

First, as shown in FIG. 2, the net 4 is spread on the field 1, the grass 2 is sprinkled to a density of about 10%, and the soil 3 is applied to a thickness of about 15 mm. Roll with a tire roller (not shown). This work will be performed from winter to spring, around the beginning of March.

In this way, the turf 2 which has been planted in the field 1 in the beginning of March is sprayed with a herbicide (simazine wettable powder) in the end of April (about 0.1 g / m ² ), and is chemically treated in the beginning of May. Fertilizer (10-10-10) was applied (40 g / m ² ). Further, weeding was performed mechanically or manually in the middle of May, and in the beginning of June, chemical fertilizer (10-10-10) was applied again (40 g / m ² ). The turf 2 thus grown is in a state in which the turf root 21 is entwined with the net 4 as shown in FIG. 3 in the middle of June, and the turf sheet 11 is completed.
The density of the grass at this point was 60 to 70%.

The finished turf sheet 11 is cut off from the field 1 by a length of about 42 m and an area of 50 m ² divided in the longitudinal direction in the state of the middle of June, and as shown in FIG.
The adhered soil 31 was thoroughly wiped off, and the roll wound 7 was then shipped. Immediately after the transplanting work was completed at the shipping destination, the progress was observed, and as a result, it was confirmed that the entire turf sheet was found to be active in the beginning of July, the density was about 80% in the middle of July, and almost bare soil in the middle of August. Disappeared, and it became completely dense in mid-September. The example of the turf sheet 11 shipped from the field 1 at this early stage is for early shipment to grow and densely grow the turf at the construction site, and if the construction date is uncertain, it can be shipped according to the construction. Is shown.

On the other hand, as shown in FIG. 1, the 50 m ² turf sheet 12 left in the field 1 was shipped to the field 1 at the time when it became dense in late August, and transplanted. I went. After that, I observed that for this turf sheet 12,
Both engraftment and vegetation progressed at the same time, and by mid-September, they had fully engrafted and became vegetative. The example of the turf sheet 12 shipped from the field 1 at this late time has a limited construction date,
It has the convenience of not needing to grow grass at the construction site.

Since the turf root 21 remains in the field 1 where the turf sheets 11 and 12 are cut off and peeled off, a new turf root 21 is left on the turf root 21 as shown in the sectional view of FIG. A new turf sheet is produced by unfolding the net 4 and applying the soil 3 and rolling it with the tire rollers. This is because the turf sheet of the present invention uses a method of integrating the turf 2 and the net 4 by entwining the turf root 21 with the net 4 instead of sandwiching the turf with a plurality of nets. Is an advantage.

In addition to the first embodiment, the turf sheet 13 may be prepared by using the turf 5 which has grown to some extent as in the second embodiment shown in the perspective view of FIG.
Can be produced. In this case, since the grass 5 has already grown, it is not necessary to apply the soil. Therefore, the first
The grass sheet 13 can be produced in a shorter time than in the case of the embodiment. In any case, these turf sheets 11,12,13
Since the grasses 2 and 5 are integrated with the net 4, it is easy to cut into a shape that matches the shape of the construction site, so it is possible to design freely assuming the grass surface after construction. .

Next, an embodiment according to the difference in net will be described. In the third embodiment, artificial turf is added to the net of the first embodiment.
As shown in the partially broken perspective view of FIG. 7, a net 41 in which 42 hairs are planted is used, and natural grass 2 and artificial grass 42 are mixed to produce a grass sheet 14 having a strong pedaling pressure. it can.
For example, when this turf sheet 14 is transplanted to a place with a lot of pedestrians such as a walking path of a golf course or a standing ground of a racetrack,
The artificial turf 42 serves as a cushioning material and is gentle to pedestrians, and at the same time, the artificial turf 42 protects the natural turf 2 from the pedaling pressure and can suppress the damage. Moreover, since the artificial turf 42 in the turf sheet 14 does not die, it is possible to maintain the appearance of the lawn surface throughout the year.

As shown in the partially cutaway perspective view of FIG. 8 as a fourth embodiment, if a net 43 woven of thick filaments made of vinylon is used, it can be applied even on the slope 81. The turf sheet 15 will not be displaced, and the construction condition can be maintained until the turf is alive and dense. In this case, as described above, the turf sheet of the present invention can be cut into a free shape and can be attached to the slope. Then, as shown in the partially broken perspective view of FIG. 9 as a fifth embodiment, when a net 44 made of coconut palm fiber is used, the grass which is strong in pedaling pressure, excellent in water permeability and breathability is used. Since the seat 16 can be produced, it can be a turf sheet suitable for a place where a lawn surface is required in a sports facility, for example, a soccer field.

Further, in the case of pursuing productivity and convenience, as shown in the partially broken perspective view of FIG. 10 as the sixth embodiment, for example, instead of the net of the net body, the communicating portion 45 of the upper and lower surfaces is formed.
By using the styrene foam mat 46 having a large number, it is possible to produce the grass sheet 17 that is lightweight and relatively easy to replace. In addition, by impregnating nets, sheets, or mats with immediate-acting or slow-acting fertilizers, or incorporating or mixing them, turf sheets can be used as turf sheets that quickly thrive and vegetate quickly. It becomes possible to grow grass on a veranda of a general household.

[0025]

According to the present invention, since it is possible to produce grass sheets that can be shipped even before grass is densely populated, the utilization rate in the field can be improved and the cost can be reduced. Conversely, since the turf sheet can be shipped regardless of the degree of growth of the turf, it will be possible to ship the turf sheet according to the enforcement time at the place where you want to grow the grass, the geological condition, etc. Than the conventional one
Flexibility in shipping is secured. Moreover, the grass used for production may be sufficiently densely grown, so by using grass that has been sufficiently grown in a field with good conditions, it is possible to avoid the risk in the field where the grass sheet is produced. .

As for the turf sheet produced, the turf sheet can be easily cut into an arbitrary shape by completely removing the adhering soil by integrating the turf and the net. So, in a narrow sense, it was tailored to the construction,
In a broad sense, it becomes possible to provide a turf sheet having a shape according to the application. In other words, the grass can be treated like a vegetated textile. Naturally, the finished turf sheet is not bulky, is light in weight, has a small volume when rolled, is easy to carry and store, and can be easily handled.

Further, paying attention to the fact that the attached soil can be brushed off, pathogens that cause diseases of grass, seeds of weeds, and pests are not brought into the construction site, and the grass roots can directly attach to the soil of the construction site (adhesion). If there is soil, an impermeable layer may be formed due to the trampling pressure). Of course, when it is preferable to have the adhered soil, it is not necessary to brush off the adhered soil, and it is also a feature of the grass sheet of the present invention that the presence or absence and the degree of the adhered soil can be adjusted.

On the other hand, the turf sheet of the present invention is made of a material having the properties such as water permeability and air permeability of the net, conversely water retention and degradability, and a structural shape as long as the turf root can be entangled. Can be a sheet or mat, and can be impregnated with fertilizer or mixed, so it is possible to maintain the life of the turf during transportation and storage, and to produce a turf sheet that is strong against treading after construction. Another advantage is that a grass sheet with high added value can be provided.
