Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to natural grass.

[0002]

2. Description of the Related Art For the production of natural turf, it has long been practiced to directly or indirectly sow it on soil or sand, grow and cultivate it, and cut the roots each time. However, the natural grass produced by such a traditional production method is not only inconvenient for operations such as harvesting, storage, transportation, construction, management and removal, but also its application field is extremely limited.

In view of such a background, recently, as shown in FIG. 4, the turf root 6 is entangled with the bark 11 accumulated in a predetermined shape in advance, and the turf roots are also entangled with each other.
The grass root 6 and the bark 11 form a series, and the grass 7 is placed on the bark 11.
It is known that vegetation was planted.

[0004]

The natural turf according to the prior art described above lays a vinyl sheet in a vast field, deposits a mixture of bark and seeds at a predetermined size at intervals, and germinates and grows. Is produced. And, the natural grass cultivated in this way is easily peeled from the vinyl sheet, can be wound in a roll shape, or can be folded and harvested, and because it is extremely lightweight, the disadvantages of natural grass by the traditional soil production method are It is resolved for the time being.

However, in the natural grass according to this prior art, since the roots of the grass are simply entangled with the bark and are entangled with each other, the rooting is weak and the harvesting, transportation, construction,
It is easy to be divided and stretches easily during any work such as removal. Moreover, since the grass roots are exposed, some kind of reinforcing material is required depending on the laying place, and when the soil is directly applied to the soil, it will die depending on the pH value of the soil. Therefore, the above-mentioned various drawbacks of the conventional techniques are fatal wounds of this kind of natural grass, and it cannot be said that the problems of natural grass produced by soil production have been corrected.

SUMMARY OF THE INVENTION The present invention is a turf and an elastic substrate.
Always placed into a series inseparable state, very tightly entangled that the grass roots in the elastic substrate, no division and elongation, moreover, it is an object to provide a natural grass rich in elasticity. Next, the gist of the present invention will be described using the reference numerals of the drawings corresponding to the embodiments. In other words, the surface 2 of the present invention is a soft synthetic resin plate-like body 1, to form a Ru substrate 4 Na secure be implanted a soft synthetic resin ring奈状product 3, the wood chip 5 on the substrate 4 As the wood chips 5 are deposited and the grass roots 6 are entangled with the wood chips 5, and the tip of the grass roots 6 entangles the ring-shaped object 3 in an unspecified direction, the board 4 is entangled. , The wood chips 5 and the turf roots 6 are inseparable from each other, and the turf 7 is planted on the wood chips 5. It should be noted that the three-dimensional object, the pile, the loop, the spiral, and the like having the narna 7 that are continuous in an unspecified direction are suitable as the narro-shaped object 3. Also,
Instead of these ring-shaped objects 3, it is also possible to provide an infinite number of intricate open cells 9 that reach from the surface 2 to the middle and holes such as tunnels. More effective.

[0007]

According to the present invention, the wood chips are
Efficiently contains fertilizers and the like to give moisture and nutrition to the grass roots, entangle the wood chips as the grass roots grow, and
The other turf root, which is adjacent to the other, is intertwined and intertwined with each other in an unspecified direction, and the root is laid down over the entire surface of the substrate of a specified size, which forms the basis of vegetation of turf. In addition, the ring-shaped object is fixed by vegetation on a plate made of soft synthetic resin to form a substrate.
Those that pass through while conflicting pre SL wood chips抱絡the Shibane the tip portion further unspecified direction Wa奈,
In addition, by embracing the wood chip buried in the ring-shaped object, the tips are intertwined with each other indefinitely together with the ring-shaped structure, so that the root is remarkably strengthened with respect to the substrate.
Chips, rims and plates are always inseparable
Become. Then, the plate-like member prevents Shibane that you penetrate the plate-like body, and to restrain the grass vegetation within that particular size, those having a function capable of construction without the Excavation Is. In addition, in the above-mentioned configuration, in the case of forming a hole such as an open cell or a tunnel in place of the ring-shaped object, the tip of the lawn root penetrates into the open cell while growing and the root is lowered to the substrate. With a flash, it has the same function as a wannabe. In this way, the grass roots entangle the wood chips, and entangle with the ring-shaped objects or open cells, so that grasses with extremely strong rooting and elasticity can be planted on the wood chips.

[0008]

EXAMPLE 1 As shown in FIG. 1, a large and small miscellaneous pattern is formed on a surface 2 of a polyurethane resin plate 1 having a thickness of 5 mm, a width of 1.2 m, and a length of 10 m, which is continuous in an unspecified direction such as vertical, horizontal, and diagonal. the polyurethane resin wheel奈状product 3 is a three-dimensional object having a wheel Nana 8, made substrate 4 flexibility be implanted to a thickness of 4mm protrusion. After laying a vinyl sheet on a flat soil of the substrate 4, wood chips 5 in which grass seeds are mixed on the entire surface of the substrate 4 are arranged at intervals of 26 mm.
Deposited with a thickness of.

After that, when water and fertilizer were given to grow naturally, the lawn root 6 entwined the wood chips 5 and entangled with each other to form the narcissus 3.
Entangled while passing through the entanglement, and because of the entanglement of the turf roots 6 with each other, the turf roots 6, the wood chips 5 , the narcissus
3 and the plate-shaped body 1 became inseparable in series, and natural grass was planted on the wood chips 5.

In addition, the height of the natural turf 7 is 35 m.
It was cut into m, wound in a roll shape from the substrate 4 to the inside, harvested, stored, transported and laid closely on a soccer field, and a soccer game was held. There were no obstacles during the competition, and there was no damage to the natural grass after the competition, so there were no abnormalities.

[0011]

Second Embodiment In place of the ring-shaped object 3 in the first embodiment, a large number of open cells 9 reaching from the surface 2 to the middle are formed integrally with the plate-like body 1 to form the substrate 10, and the other embodiments are used. When carried out in the same manner as in Example 1, the tip of the lawn root 6 was bulged while curving the inner surface of the open cells 9 in a serpentine shape, and the others were the same as in Example 1.

[0012]

According to the present invention, the following unique effects are exhibited. Since wheel奈状was a plate-like body is vegetation fixed, Shibane was抱絡the U Tsu <br/> Dochippu further, since entangled to a wheel奈状 was Shibane, wood chips, Wa奈Whole of sheet and plate
Becomes a series of inseparable, and the vegetation of turf becomes extremely strong. As described above, the vegetation of the turf is strong, and the turf is restrained by the substrate itself, so that the turf does not split or expand or contract. Since both the plate-shaped body and the ring-shaped body are made of soft synthetic resin, this substrate has elasticity, strong corrosion resistance, and light weight, and there is no division or expansion / contraction. From
Wound up into a roll can, harvesting, storage, transportation, construction,
Highly removable. Since the grass roots are restrained by the substrate, the contact of the grass roots with the laying ground is blocked, the grass roots can be laid in any soil regardless of the pH value, weeds generated from the soil do not grow, and the grass roots are entangled. It is possible to prevent falling and outflow of wood chips. For example, soccer in humans Koshiba stadium is one that is not certified. In this case, however, a vinyl sheet is laid on the artificial turf, and the natural turf according to the present invention is precisely laid on the vinyl sheet, which is regarded as an official match. According to the present invention, the rooting of the grass on the substrate is extremely strong, and
Soft synthetic resin ring-shaped object forming plate and soft synthetic resin
Since the plate-shaped body has elasticity, these are sequentially clicked.
