Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a material for protecting grounds and slopes, and more particularly to a vegetation cylinder and a vegetation seedling suitable for protecting grounds and slopes by vegetation.

[0002]

2. Description of the Related Art The protection of natural grounds and slopes (hereinafter simply referred to as slopes) is sometimes performed by hardening concrete, but in order to make the landscape beautiful and the slopes are strengthened by rooting. For the reason that various kinds of protection can be performed, plant protection methods, so-called vegetation, have become popular.

In the conventional vegetation, a frame made of metal or synthetic resin is formed on the slope and the seeds of vegetation plants are sprayed with the vegetation base material or the seeds are put together with the vegetation base material. A large number of the vegetation bags were attached to a net made of synthetic resin and the net was stretched on the slope. In this case, the frame and net are used to prevent soil on the slope and seeds planted on the slope from being washed away by rainwater, etc. It is a thing.

However, since the components such as the frame and the net are made of a non-corrosive material such as metal or synthetic resin, they remain on the slope even after the vegetation is completed. Frames and nets remaining on such slopes will not cause any particular problems, but if possible, if they disappear into the slopes after the completion of vegetation, the protected slopes will be in a natural state. It is thought that they can be brought closer and the environment can be kept good.

[0005] Also, when constructing this type of vegetation method, it is important to consider that seeds of vegetation plants are used so that a sufficient germination rate can be secured. When using seedlings of vegetation plants, it is necessary to ensure a sufficient rooting rate. In other words, simply planting the seeds of the plant on the slope by means such as spraying does not mean that the vegetation method is completed, and that planting seedlings does not mean that it is enough. After construction, seeds must germinate and grow well, and seedlings must be well rooted.

The use of seedlings can solve the problem of germination rate and can be applied, but it is difficult to carry the seedlings on the slope, especially on steep slopes and natural ground. A large hole must be formed. Moreover, as shown in FIG. 5, in order to prevent the soil around the roots from being dropped, the roots of the seedlings are tied around with a rough rope, which adversely affects the growth of the shoots. There is a situation in which it prevents the sufficient rooting of the slope.

Furthermore, since seeds and seedlings for vegetation are living things, they must be constructed in the most suitable season (for example, March to May), and a large amount of them are required during that season. In other words, a large amount of seeds and seedlings for vegetation are needed in the optimal season for vegetation work, and trying to meet such demand is very expensive, for example, having to prepare a large seedling. It becomes.

Therefore, the inventors of the present invention fundamentally changed the components such as the frame and net so that the vegetation work itself can be easily performed, and these components are completely lost after the vegetation is completed. In addition, as a result of various studies on how to improve the germination rate / rooting rate, as a result of the new discovery that the biodegradable resin brings good results, the present invention was completed. Of.

SUMMARY OF THE INVENTION The present invention has been made based on the above-described background, and the problems to be solved are to make vegetation work easier and to complete vegetation after completion. It is to make the constituent materials familiar to the natural environment.

That is, the object of the invention according to claim 1 is that the manufacturing itself is simple, the construction work for vegetation can be easily performed, and when the vegetation is completed, It is to provide a vegetation cylinder that can be made to be the same as the surface.

Further, the object of the invention according to claim 2 is to put a vegetation base material and seedlings or seeds of vegetation plants in the vegetation cylinder according to the above-mentioned claim 1 and to put them directly on the slope. Another object is to provide vegetation seedlings that can be constructed and are easy to manage so-called products with a simple configuration.

[0012]

Means for Solving the Problems In order to solve the above problems, the means adopted by the invention according to claim 1 will be described with reference to the symbols used in the description of the following embodiments. Vegetation cylinder 10 integrally formed of a biodegradable resin that is completely or partially decomposed by a microorganism such as middle grade
A tubular portion 11 filled with the vegetation base material 20 and the like, and a pointed portion 12 formed continuously from the tubular portion 11 to close one end of the tubular portion 11 and to satisfactorily embed it in the soil. The vegetation cylinder 10 made of a biodegradable resin, characterized in that the vegetation cylinder 10 is made of a biodegradable resin, and has a plurality of openings 13 formed in the cylinder part 11 to secure the water absorption and to improve the root extension of the vegetation plant into the soil. Is.

That is, since the vegetation cylinder 10 is integrally formed of a biodegradable resin, it is biodegraded by microorganisms such as bacteria and bacteria in the soil after the construction is completed using the vegetation cylinder 10. Then, part or all of it is changed to carbon dioxide and water. For this reason, cuttings 3 which are seedlings of vegetation plants
1 and plant seeds 32 and the like grew sufficiently on the slope 40 (about 6 months to 1 year after construction), the vegetation cylinder 10 had almost no shape on the slope 40. This means that the surface 40 is homogenized. Therefore, when the vegetation cylinder 10 according to the present invention is used for vegetation, the slope 40 can be brought into a state close to nature and the landscape can be made beautiful.

Various types of biodegradable resins are conceivable for constructing such a vegetation cylinder 10, and they are roughly classified into two types, that is, a completely degradable type and a partially degradable type. Completely degradable biodegradable resins include "polyhydroxybutyrate" derived from microorganisms, "blend product of starch and synthetic polymer" derived from natural polymers, and "polycaprolactone, polyglycol, Lactic acid "
Etc. Further, as the partially degradable biodegradable resin,
Examples include blended products of starch and polyethylene, and polyblended products of polycaprolactone and general-purpose plastics.

Of these biodegradable resins, for example, polyhydroxy plate, polyglycolic acid, etc. are difficult to mold, but the vegetation cylinder 10 is composed of a cylinder part 11 and a pointed part 12. Moreover, since it is constructed as described below, there is no need to make it particularly strong. Therefore, if the materials to be blended with these are taken into consideration, the molding difficulty can be resolved. For example,
Polylactic acid, which is the same biodegradable resin, has already been developed as a technology for molding it into a fibrous material.
If the fibers made of polylactic acid are mixed into the biodegradable resin having the above-mentioned molding difficulty, it is possible to obtain the vegetation cylinder 10 having the minimum necessary rigidity.

In order to construct the slope 40 using this vegetation cylinder 10, first, a vegetation seedling 100 as shown in FIG. 3 is obtained. That is, whether the vegetation cylinder 10 is filled with the vegetation base material 20 and the cuttings 31 which are seedlings of the vegetation plant are planted in the vegetation base material 20 (in the case of (a) of FIG. 3),
The plant seeds 32 for vegetation are sown on the upper surface of the vegetation base material 20 (in the case of (B) of FIG. 3). The thus-prepared vegetation cylinder 10 is directly embedded in the construction hole 41 formed in the slope 40 as shown in FIG. In this case, since the lower end of the vegetation cylinder 10 is the pointed portion 12, the pointed portion 12 divides the soil in the construction hole 41 laterally during construction.
The burial work can be done easily.

After the construction as described above, not only rainwater or the like enters from the upper end opening of each vegetation cylinder 10, but also water in the soil is supplied from each opening 13 formed in the cylinder part 11. It will be. Further, from each opening 13, the cutting 3
1 and not only the oxygen necessary for the roots of the plant seeds 32 to grow is supplied from the soil side, but FIG.
As shown in (b) of (3), the root system 33 of the vegetation plant easily extends into the soil through the opening 13.

Of course, this vegetation cylinder 10 is completely in the process until the cuttings 31 and the plant seeds 32 extend the root system 33 and reach the slope 40 sufficiently (for about 6 months after construction). Since it is not biodegraded, the vegetation base material 20 is held against the slope 40, and the root system 33 and the like of the vegetation plant grows in a stable state. Further, in the illustrated vegetation cylinder 10, the cylinder portion 11 is a straight one having the same inner diameter, but the cylinder portion 11 may be implemented as a taper-like shape that expands toward the opening like a bucket. .
It is needless to say that if this is done, the vegetation cylinders 10 can be stacked (stacked), and the dead space during transportation and storage can be reduced.

In order to solve the above-mentioned problems, a second aspect of the present invention is provided.
Means adopted by the invention according to, when described with the reference numerals used in the description of the following embodiment, "integrally formed by biodegradable resin that is completely decomposed or partially decomposed by microorganisms such as soil The tubular portion 11 and the pointed portion 12 which is formed continuously with the tubular portion 11 to close one end of the tubular portion 11 to make the embedding in the soil good and which is formed in the tubular portion 11 to absorb water. , A vegetation cylinder 10 composed of a plurality of openings 13 for improving the tension of the roots of the vegetation plant into the soil, and an improving material, a rooting agent, a water retention material, etc. filled in the vegetation cylinder 10. , Or a seedling or seed of a vegetation plant planted in the vegetation base material 20, and a vegetation seedling 100 ".

That is, the vegetation seedling 1 according to claim 2
00 is a seedling of a vegetation plant with respect to this vegetation base material 20 as shown in FIG. 3A while filling the vegetation cylinder 10 according to the above-mentioned claim 1 with the vegetation base material 20. The cuttings 31 are planted, or, as shown in (b) of FIG. 3, plant seeds 3 to be vegetation plants are provided on the covering portion of the vegetation base material 20.
The planting work is completed by sowing No. 2 and constructing it on the slope 40 as it is.

Therefore, according to the vegetation seedling 100 according to the second aspect, when the cuttings 31 as the source of the vegetation plants are adopted, the whole is kept cool, and the plant seeds 32 are employed as the sources of the vegetation plants. In such a case, if the vegetation base material 20 is not given water, the growth and rooting of the cuttings 31 or the germination of the plant seeds 32 can be stopped, and if a large amount is not used seasonally. The vegetation plants can be stored in a dormant state in case they do not happen. Of course, if the vegetation seedlings 100 using the cuttings 31 are constructed in a warm season, the temperature for rooting is naturally added, and the rooting of the cuttings 31 will start after construction. It goes without saying that, in the vegetation seedling 100, if water is poured into the vegetation base material 20, each plant seed 32 will germinate and start growing.

When the cuttings 31 are adopted as the vegetation plants and the vegetation seedling 100 as described above is obtained, the relationship between the cuttings 31 and the vegetation cylinder 10 may be as shown in FIG. That is, the vegetation seedlings 100 may be arranged in the center of the vegetation cylinder 10 so that the vegetation seedlings 100 may be arranged with respect to the slope 40. If the cuttings 31 are located at the center of the vegetation cylinder 10, the root system 33 of the cuttings 31 can extend from any of the openings 13 of the vegetation cylinder 10 into the slope 40, and the root system 33 that normally extends downwards. The vegetation cylinder 10 will no longer be in the way.

The vegetation seedling 100 constructed as described above is
As shown in (a) of FIG. 2 and the like, it may be buried as it is in the construction hole 41 formed in the slope 40, which completes the construction for vegetation. Of course, if the slope 40 is hard rock such as natural ground, the construction hole 4
1 must be made by mechanical drilling, but the drilled construction hole 41 is rather useful for holding this vegetation seedling 100 because the surrounding area is rock. Of course, since the vegetation base material 20 for vegetation plants is put in the vegetation seedlings 100, bedrock does not pose a problem for the growth of vegetation plants.

Therefore, according to this vegetation seedling 100, the vegetation plant which is a living thing is possessed while having the advantage that the workability of the vegetation cylinder 10 according to claim 1 is improved. Even if there is, it can be easily stockpiled in case it is used in large quantities.

[0025]

BEST MODE FOR CARRYING OUT THE INVENTION Next, each invention will be described according to the embodiments shown in the drawings. FIG. 1 is a partially cutaway front view of a vegetation cylinder 10 according to claim 1. This vegetation cylinder 10 uses polylactic acid fiber made of polylactic acid resin produced as a raw material, for example, by hydrolyzing a glucose source such as plant starch with an enzyme and then subjecting this to lactic acid fermentation to produce a dimer of lactic acid. And integrally molded.

As shown in FIG. 1, FIG. 3 or FIG. 4, the vegetation cylinder 10 is formed by a cylinder portion 11 filled with the vegetation base material 20 and the like and a continuous portion of the cylinder portion 11. A pointed portion 12 that closes one end of the tubular portion 11 to improve the embedding in the soil
And a plurality of openings 13 which are formed in the tubular portion 11 to secure the water absorption and to make the roots of the vegetation plants adhere well to the soil. The size of the cylindrical portion 11 and the pointed portion 12 is
Although it is variously changed depending on what is selected as a vegetation plant for performing vegetation, a cylindrical shape as shown in FIG. 4 can be easily manufactured, stored or constructed, Alternatively, it is most preferable for the reason that it can be easily handled, but it goes without saying that the cross section may be square.

Using such a vegetation cylinder 10, the slope 4
When the protection of 0 is performed, the vegetation base material 20 and the vegetation plants may be put in the vegetation seedling 100 described later and then applied to the slope 40, as shown in FIG. As shown in (a), the vegetation cylinder 10 is provided with the construction holes 4 on the slope 40.
It is also possible to embed the vegetation base material 20 and vegetation plants after burying the vegetation base material 1 inside. To form the construction hole 41 on the slope 40, the construction hole 41 shown in the uppermost part of FIG. The hole may be removed as a large one.
In addition, the second construction hole 41 shown in FIG.
As described above, even if a relatively large construction hole 41 is formed in the slope 40, and the vegetation cylinder 10 is housed in the construction hole 41, the construction is carried out so that the vegetation cylinder 10 is filled with soil. Good.

In the vegetation cylinder 10 as described above, a vegetation base material 2 made of a soil improving material, a rooting agent, a water retaining material, a fertilizer, etc.
By filling with 0 and planting or sowing cuttings 31 or plant seeds 32 of vegetation plants, the vegetation seedling 100 according to claim 2 as shown in FIG. 3 is obtained.

That is, the vegetation seedling 100 shown in (a) of FIG. 3 employs the cuttings 31 as seedlings of the vegetation plant and is rooted to some extent before the slope 40 is constructed. . Further, the vegetation seedling 100 shown in FIG. 3B is obtained by sowing plant seeds 32 in an upper portion of the vegetation base material 20 in the vegetation cylinder 10. In the vegetation seedling 100 of the present embodiment, as shown in FIG. 3, a protective material 21 formed of natural fibers such as pulp or biodegradable resin is provided on the upper surface of the vegetation base material 20 filled in the vegetation cylinder 10. It is arranged. The protective material 21 prevents the vegetation base material 20 filled in the vegetation cylinder 10 from spilling during transportation or construction, and is decomposed by microorganisms or the like when the vegetation plant grows to some extent. Is. Needless to say, it is possible to prevent the vegetation base material 20 from spilling from each opening 13 by covering each opening 13 on the vegetation cylinder 10 side from the inside with such a protective material 21.

The reason why the cuttings 31 are used as seedlings for vegetation is that there is a desire to make flowering trees that are difficult to obtain seeds and germinate into vegetation plants. As such cuttings 31, hydrangea, The deciduous flowering trees such as Noriyutsugi and Azalea, and evergreen flowering trees such as Hisagaki, Quercus chinensis and Gardenia are specifically considered. If the mother tree for forming such a cutting 31 is kept cold in winter, it can be put into so-called hibernation, and the cutting tree 31 cut from this mother tree
Is convenient because rooting takes place in about 1 to 2 weeks only by releasing the cold insulation. Also, with such cuttings 31 planted,
If the entire vegetation seedling 100 is kept cold at a temperature of 1 to 3 degrees, it can be stored for a long period of 5 years or more.
