Description

Detailed Description of the Invention

[0001]

The present invention relates to a turf seedling and a method for producing the same,
More specifically, it is excellent in water retention, not only easy to grow grass, but also to prevent grass from dying at the time of transfer to plant a seedbed with germinated grass in another place. The present invention relates to a turf seedling suitable for laying and using in a stadium and a manufacturing method thereof.

[0002]

2. Description of the Related Art Conventionally, turf is grown in a certain place, and the germinated turf is transferred to another place together with the soil having roots,
The grass was being planted at the transfer destination. In such a case, it is possible to efficiently grow the grass, transfer the grown grass that has sprouted to another place without dying, and not letting the transferred grass die at the transfer destination. is necessary.

Explaining in more detail here, in order to "grow grass efficiently", the seeds before germination or the grass after germination are protected from pests and diseases, and a certain amount of water is always kept before seed germination or germination. It was necessary to feed the grass. In addition, in order to “transfer the grown and sprouted grass to another place without dying”, first remove the grass from the ground along with the soil around the roots, and always keep the grass constant during transfer so that it does not die. It was necessary to keep water on the grass after germination.

Further, in order to prevent the transferred grass from dying at the transfer destination, it was necessary to familiarize the transfer target soil with the soil around the root and the grass separated from the ground.
From such various needs, for example, JP-A-53-75
As in the invention described in Japanese Patent No. 035, there has been provided "a vegetative carpet in which the whole root is invaded into a thin layer of compost composed of crushed bark, which itself serves as a supporting tissue".

In this vegetation carpet, seeds are mixed in a compost composed of crushed bark, and the seeds are germinated in the compost, whereby the roots of the germinated plants penetrate into the compost. Therefore, with respect to the turf after germination, it is possible to very easily grow, transfer, and transplant the turf by peeling it from the ground together with the compost and transplanting it onto the soil of the transfer destination.

[0006]

However, in the invention described in Japanese Patent Laid-Open No. 53-75035, the seeds before germination or the turf after germination are protected from pests and a certain amount of water is always kept before germination. It is extremely difficult to give seeds or turf after germination, and it takes a lot of time and labor to rehydrate, especially in the dry season.

Furthermore, although the grass after germination is separated from the ground together with the compost and transplanted onto the soil of the transfer destination, if the water is not replenished, the grass will be dead. It was supposed to take a lot of time to rehydrate. Therefore, while protecting the seeds before germination or the grass after germination from pest damage, it is possible to maintain a certain amount of water at all times to efficiently grow the grass, and without killing the germinated grass that has been grown. The invention described in JP-A-4-40827 is provided as a grass seedling and a method for producing the same, which can be easily transferred to a place where the transferred grass does not die at the transfer destination. It came to be offered.

According to the present invention, a seed bed is a mat formed by mixing a granular water-absorbent resin into a thin layer made of crushed virgin bark. Such a nursery is
It is suitable for use by spreading it in a garden etc., and efficiently growing grass as described above, transferring the grown grass that has sprouted to another location without dying, and transferring. It was sufficient to prevent the turf from being dried at the destination.

On the other hand, in recent years, various athletic competitions have become popular. Among such various competitions, for example, while professional baseball is often played on an artificial grass ground, professional soccer is supposed to be played on natural grass. Therefore, if there is a natural grass field, you can play professional baseball and professional soccer, but if you have an artificial grass field like many baseball fields, you can play professional baseball but you can not play professional soccer. It was. Furthermore, it was not possible to hold professional soccer on the ground such as Antukar, where it is assumed that natural grass is used.

Therefore, it is conceivable to lay the lawn seedling proposed in the invention described in JP-A-4-40827 on the ground. In this way, it is possible to hold a professional soccer or the like in place of the natural grass ground, whether it is an artificial grass ground or an unplayed ground. However, as a result of the experiment, when the grass seedling proposed in the invention described in JP-A-4-40827 is laid and used as it is on the ground, the seams of adjacent grass seedlings may be flipped when sliding. Or, there is a gap between adjacent lawn seedlings,
Furthermore, some grass in a single lawn seedling was peeled off, and it was not suitable for actual use.

As a result of confirming such a cause, it is a matter of course that one of the causes is that the adjacent grass seedlings are not fixed, but in addition, the grass is rooted in the ground. This is probably because some turf easily peels from the turf seedlings.

[0012]

Therefore, the present invention is based on a lawn seedling proposed in the invention described in Japanese Patent Application Laid-Open No. 4-40827, and has a base having substantially the same plane shape as this seedbed and having a large number of root holes. By forming a member, locating the seedbed on the base member, and forming the roots of the seedbed turf in the root hole of the base member to form a sliding member, by fixing the seedbed to the base member by the roots. Even if it is done, some turf is prevented from peeling from the turf seedlings, and the seams of adjacent turf seedlings are turned up or there is a gap between adjacent turf seedlings. It is an object of the present invention to provide a turf seedling that is prevented from doing and a method for producing the same.

[0013]

In order to achieve the above-mentioned object, the invention according to claim 1 of the present invention is a granular water absorbent resin in a thin layer composed of crushed virgin bark. The mat formed by mixing the seedlings with a lawn as a seedbed is formed into a planar rectangular shape, and the seedbed has almost the same planar shape as the seedbed and has a large number of root holes and has a biting portion on the lower surface. A base member is formed, the seedbed is positioned on the base member, and the roots of the grass of the seedbed are entwined with the root holes of the base member.

According to a second aspect of the present invention, virgin bark is crushed and formed, and turf seed and granular water-absorbing resin are mixed into the vertices to form a flat rectangular mat. The turf is germinated, and after germination, the seedbed formed by the mat and the germinated turf is peeled off, while the seedbed has substantially the same plane shape and a large number of root holes,
A base member having a biting portion on the lower surface is formed, the seedbed is positioned on the base member, and the roots of the lawn of the seedbed are entwined with the root holes of the base member.

Furthermore, the invention according to claim 3 is one in which turf seeds and granular water-absorbing resin are mixed into crushed virgin bark to form a flat rectangular mat-like material, and the matte lower surface is formed. In the state where a base member having a large number of root holes is positioned, and further a sheet having a large number of water holes, which are drainable but do not allow the roots to enter, is positioned on the lower surface of the base member, the mat is placed. The turf inside was germinated, and after germination, the nursery formed by the mat and the germinated turf was peeled off together with the base member with the roots entangled.

[0016]

In the lawn seedling according to the present invention, a mat formed by mixing granular water absorbent resin into a thin layer composed of crushed virgin bark is used as a nursery bed. In addition, such a nursery bed is formed by crushing virgin bark into which mats of grass seeds and granular water-absorbing resin are mixed are formed into a mat, and the grass is germinated in the mat, and after germination, It can be obtained by peeling the nursery formed by the mat and the germinated turf.

On the other hand, in the turf seedling according to the present invention, in addition to the seedbed, a base member having substantially the same planar shape as the seedbed and having a large number of root holes is formed. Then, by placing the seedbed on the base member and further growing grass, the roots of the grass are entangled with the root holes of the base member, and the seedbed and the base member are integrated.

In this case, the base member is placed on a sheet having a large number of water passage holes which are drainable but whose roots do not enter, or a waterproofed concrete, to grow grass. By doing so, the roots of the turf are easily entangled in the root holes of the base member, and the seedbed and the base member are more firmly integrated. Therefore, when laying the lawn seedlings, the biting portion of the base member bites into the ground so that the lawn seedlings will not be displaced. As a result, even when sliding, some grass is prevented from peeling from the grass seedlings, the seams of adjacent grass seedlings are turned over, or there is a gap between adjacent grass seedlings. It is possible to prevent it from being completed.

Since virgin bark is used here,
A resin is mixed in the bark, and this resin can protect seeds before germination or grass after germination from pests and diseases. Furthermore, since the water absorbent resin is mixed in the seedbed, when water is given, the water is absorbed and held by this water absorbent resin, so it should be temporarily dried when the lawn seedling is not used. However, the water in the water absorbent resin is supplied to the seed before germination or the grass after germination.
Therefore, it is possible to maintain a constant water content in the nursery at all times, so that it is possible to efficiently grow grass and transfer the grown grass to the other place without dying the germinated grass. The turf does not die at the destination.

[0020]

Embodiments of the present invention will be described below with reference to the drawings. 1 is a cross-sectional view of a mat-shaped nursery bed in a state before germination, FIG. 2 is a cross-sectional view of a mat-shaped nursery bed in a state after germination, FIG. 3 is a cross-sectional view of a turf seedling according to the present invention, and FIG. It is sectional drawing for demonstrating the other manufacturing method of the lawn seedling which concerns on this invention.

First, the production of a nursery bed will be described with reference to FIGS. 1 and 2. First of all, the virgin bark 10 is not powdered and has a maximum diameter of 10
Grind to about mm. For this diameter,
If you make it too large, it will be difficult to form a mat-shaped nursery,
On the contrary, if it is too small, the air permeability is lowered, so that the maximum diameter is preferably about 10 mm.

[0022] Then with respect to the virgin bark 10 1 m ^3, a seed 20 lawn about 75 kg, to form a mixture of the water absorbing resin 30 is mixed about 2 kg. In addition, here, since the water absorbent resin 30 is mixed in a dry state,
Although the diameter is about 150 to 250 μm, the maximum diameter is about 2 to 3 mm by absorbing water. Further, specifically, it is preferable to use "Igetagel P (trade name, trademark)" manufactured by Sumitomo Chemical Co., Ltd.

Further, if necessary, virgin bark 10
1 m ³ of lime, 3 kg of lime and magnesium sulfate of 0.
Appropriate fertilizers such as 5 kg or 3 kg of compound fertilizer can be mixed. Then, this mixture is spread to a thickness of about 20 to 35 mm on the soil that has excellent drainage and is in a horizontal state before the seeds 20 of the lawn are germinated in the mixed state to form a mat-shaped mixture. A seedbed 40 is formed (see FIG. 1).

At this time, if the mat-shaped nursery bed 40 is pressed from the upper surface, it is possible to prevent the seeds 20 and the like from flowing out due to watering. After making such a state, sprinkling water and adding a fertilizer containing nitrogen as needed are performed. At this time, in the mat-shaped nursery 40 according to the present invention, since the virgin bark 10 is used, it is in a state of containing resin or sap, and the seed 20 before germination or after germination is caused by this resin or sap. It can protect the lawn grass from pests and diseases. Of course, the effect of using the bark 10 is that although it suppresses the evaporation of water, it also has the effect of good air permeability.

Since the water absorbent resin 30 is mixed in,
It does not require frequent watering and can be easily managed. Furthermore, when cultivated in a high temperature area,
Although high temperature accelerates the growth, the labor required for watering can be saved and efficient growth can be achieved. In this way, when the mat-shaped nursery 40 is formed, and water is sprinkled and a fertilizer containing nitrogen is added as needed, about 4 to
It will germinate in 6 weeks and the turf 50 will grow (see FIG. 2).

Therefore, although it is possible to ship in this state, it is preferable to mow the grass 50 once at the first germination and mow the grass 50 after 1 to 2 weeks, and at the same time prepare for shipment. Then, the roots 60 are sufficiently stretched in the seedbed 40, and are easily separated from the soil in which the seedbed 40 is grown. Of course, if the growing is continued in the first growing portion for a longer period, the grass 50 becomes more durable.

Before the seed bed 40 is peeled from the soil thus grown, the seed bed 40 is filled with water and dispersed so that the water-absorbent resin 30 absorbs a sufficient amount of water. It is not necessary to sprinkle water before planting first. Further, at the time of peeling, it is peeled after being cut into strips having a constant width, or by being cut into rectangular plates having a constant size.

In the turf seedling according to the present invention, it is necessary to form the seed bed 40 and the base member 70 as described above. Here, the base member 70 is formed to have a large number of root holes 71. As such a base member 70, a plate-shaped member formed of plastic or a band-shaped member formed of soft plastic can be used as long as it has a large number of root holes 71. The root hole 71 is the root 6 of the turf 50.
Since it suffices for 0 to pass, the base member 70 itself can be formed as a net-shaped member.

Further, after the base member 70 was prepared in this way, the mat-shaped nursery bed 40 was formed, and watering and addition of nitrogen-containing fertilizer as needed were carried out.
The seedbed 40 in a state where the turf 50 germinated in 6 weeks, or the lawn 50 was once mowed at the time of the first germination, and the seedbed 40 in which the turf 50 was trimmed when a further 1 to 2 weeks had passed, the first nurturing spot was peeled off. The lawn 50 is placed on the base member 70, and the lawn 50 is further grown while sprinkling water and adding a fertilizer containing nitrogen as needed.

Then, the turf 50 is further grown, and eventually the turf 5
The roots 0 of 0 broke through the lower surface of the nursery 40, and the base member 70
Will be reached. As a result, the root 60 of the turf 50 of the seedbed 40 protrudes below the base member 70 through the root hole 71 of the base member 70, and eventually the root 60 of the turf 50 may integrate the seedbed 40 and the base member 70. Yes (see Figure 3).

Further, as described above, the root hole 7 of the base member 70 is formed.
When entwining the root 60 of the turf 50 of the nursery 40 with 1
By positioning the base member 70 on a sheet in which the pores of the turf 50 are not penetrated and growing, the root 60 once reaching the lower part from the root hole 71 is again placed in the root hole 71. It is possible to ensure the engagement between the base member 70 and the seedbed 40 when entering.

Similarly, when the base member 70 is placed on the waterproofed concrete and the seedbed 40 is positioned on the base member 70, the root hole 71 is once moved downward as described above. The root 60 reenters the root hole 71, so that the base member 70 and the seedbed 40 can be more securely engaged with each other. Then, the seedbed 40 is filled and dispersed with water, stored in a state where the water absorbent resin 30 has sufficiently absorbed the water, and laid on an artificial grass ground, an ant-car ground, etc., as necessary, and the artificial grass ground or an It can be used in place of a turf ground or the like for a natural grass ground.

In addition to the athletic field, the base member 70 is previously placed on the roof of a general household,
The seedbed 40 is placed on the base member 70 and the grass 5
You can also train 0. When formed in this manner, the roots 60 of the grass 50 of the nursery 40 are entangled with the root holes 71 of the base member 70, so that even if the roots 71 are violently moved on the rooftop, a part of the grass 50 is peeled off from the seedlings together with the roots 60. It is possible to prevent this from happening, and it is possible to further prevent the seams of the adjacent grass seedlings 40, 40 from being turned up, or the gaps between the adjacent grass seedlings 40, 40 from being formed.

Next, another method for producing a lawn seedling according to the present invention will be described with reference to FIG. In this embodiment, a mixture of seed 20 of turf 50 and granular water-absorbent resin 30 formed by crushing virgin bark 10 is formed into a flat square mat-like shape, and a large number of mats are formed on the lower surface of the mat. The base member 70 having the root hole 71 is located, and the base member 7
After sprouting the turf 50 in the mat in a state where the sheet 80 having a large number of water passage holes 81 having a size that does not allow the root 60 to enter the lower surface of the mat 0 is positioned, The seedbed formed by the mat and the germinated turf 50 is peeled off together with the base member 70 in which the root 60 is entangled.

Here, it is desirable that the water passage holes 81 have a diameter of 2 mm or less and a pitch of about 3 to 5 cm. When the grass 50 is grown in this manner, the roots 60 of the grass 50 grow downward as the grass 50 of the nursery 40 grows, and eventually,
The root 60 extends downward from the root hole 71 of the base member 70. However, since the seat 80 is located on the lower surface of the base member 70, the root 60 thus extended does not extend below the seat 80, and conversely the base member 70 is extended.
From the root hole 71 of the above, it will invade the seedbed 40 again.

Here, instead of the sheet 80, the base member 70 may be placed on waterproof concrete to grow the grass 50. Therefore, when the turf 50 is grown in this manner, the roots 60 of the turf 50 are well entangled with the root holes 71 of the base member 70, and the base member 70 and the nursery 40.
Ensuring engagement with and raising seedbed 4 once
It is possible to save the trouble of placing 0 on the base member 70 and further growing it.

When the root 60 of the turf 50 is well entangled with the root hole 71 of the base member 70 in this manner, even if a force is applied to some turf 50 by sliding or the like, the turf 50 will not be removed.
Since the root is entwined with the root hole 71 of the base member 70 by the root 60, only a part of the grass 50 is not peeled off. A strip-shaped member formed by peeling the lawn seedling 40 into a strip and formed of soft plastic as the base member 70,
Alternatively, if a member on the net is used and the lawn seedlings are fixed to the base member 70 by the roots 60 of the lawn 50, the lawn seedlings can be wound during storage when not in use.

The turf seedling described above is made of the water-absorbent resin 30.
Not only can the number of times of water spraying be reduced by this, but evaporation of water can be reduced by the bark 10, and storage or management becomes extremely easy. In the above description, the virgin bark 10 refers to a bark that has not yet been used for such a purpose, and does not necessarily mean immediately after being stripped from a tree.

[0039]

As described above, according to the present invention, the turf seedling proposed in the invention described in JP-A-4-40827 is
A base member having substantially the same plane shape as this seed bed and having a large number of root holes and having a biting portion 72 on the lower surface is formed, and the seed bed is positioned on the base member to form a base of the lawn of the seed bed. The seedbed is fixed to each base member by roots by being formed by being entwined with the root hole of the member, and by fixing this base member to the ground by the biting part 72, even when sliding, etc. This prevents some of the grass from peeling from the inside, and also prevents the seams of adjacent turf seedlings from turning over or forming a gap between adjacent turf seedlings.
