DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vegetation substrate suitable for use in a greening method such as a slope.

[0002]

2. Description of the Related Art In recent years, for example, in the field of greening slopes,
Revegetation technology that uses cardboard, old newsprint, and other paper sheets that are used paper as a vegetation base, supports plant seeds as necessary, and stretches the vegetation base on a slope, for example, in a bare ground. Is getting attention.

According to this greening technique, erosion of the surface soil of the slope is effectively prevented by the vegetation base, and greening of the slope is suitably achieved by the plant seeds carried on the vegetation base. And since the vegetation substrate is a sheet made of paper, which biodegrades over time,
The vegetation substrate is preferred in that it does not remain on the slope as residue.

[0004] In particular, the amount of waste in containers and packaging has increased with the expansion of production and consumption, diversification of lifestyles, and changes in consumer consciousness accompanying the recent economic development, and the environmental awareness has increased the awareness of recycling. Today, separate collection and re-commercialization have been implemented, and the use of corrugated cardboard as a vegetation substrate used in the above-mentioned greening method is a method that is significant in terms of resource conservation and environmental conservation. It is.

[0005] By the way, when a paper sheet is used as a vegetation substrate, it is necessary to form an opening in the paper sheet to make the seeds of plant seeds pass well.
Using a punching machine, countless punch holes were formed in the paper sheet.

[0006]

However, when a punching process is performed, a large amount of paper punched out of punched holes is generated as garbage, and not only resources such as corrugated cardboard and old newspaper are wasted, but also post-processing of the paper strip. There are also problems in terms of
From the germination surface of the plant seeds, it is preferable to form many punch holes, but in addition to the above problem becoming more remarkable, the tensile strength in the plane direction of the paper sheet decreases. But there was a problem.

SUMMARY OF THE INVENTION The present invention has been made in view of such circumstances, and has as its object to reduce the strength of a paper sheet which is not problematic in post-processing and the like without a significant decrease in tensile strength. An object of the present invention is to provide a vegetation substrate having no occurrence and having an opening for germination of plant seeds formed in a paper sheet.

[0008]

The technical means adopted by the present invention to achieve the above object are as follows. That is, as a vegetation substrate made of a paper sheet, a cut forming zone and a cut-free zone are alternately set in the width direction of the sheet in the paper sheet, and the cut in the sheet width direction is formed in the cut forming zone in the longitudinal direction of the sheet. And a half of the sheet strip between the cuts is bulged to one side of the sheet (claim 1).

According to the above construction, the opening for plant seed bud formation is formed in the bulging portion of the sheet strip without producing any punched paper piece which is a problem in post-processing. In addition to no waste of paper, the sheet made of paper has an uncut zone continuous in the longitudinal direction of the sheet, and further, since the sheet strips are continuous in the width direction of the sheet, No significant decrease in tensile strength is caused.

In forming the opening for buds, when the paper sheet is made of, for example, corrugated cardboard, only about half of the sheet strips are bulged to one side of the sheet so as to crush the sheet strips. Although it is possible, from the viewpoint of minimizing the crushing of the sheet strip as much as possible, it is preferable that about half of the remaining sheet strip be bulged to the other side of the paper sheet (claim 2).

It is also possible to select every two or three sheet strips and bulge them.
In order to form the vegetation substrate with a uniform thickness,
It is preferable to swell every other.

From the viewpoint of the tensile strength, it is preferable that the uncut zone is continuous over the entire length of the sheet in the longitudinal direction of the sheet, and the plurality of uncut zones are provided in the width direction of the paper sheet. ), The cut forming zone and the cut-free zone may be provided alternately in the longitudinal direction of the sheet, that is, the cut forming zone and the cut-free zone may be provided over the entire surface of the sheet, for example, in a checkered pattern. It is.

Preferably, at least one of plant seeds, fertilizers, and soil conditioners is supported on one side of a paper sheet with a sizing agent (claim 4). ,
One or more types of fertilizers and soil conditioners are carried on one side of a sheet material by a paste, and the sheet material is adhered to one side of a paper sheet (claim 5).

[0014]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a state of protection and greening of a slope N by a vegetation substrate 1 made of a paper sheet, and a vegetation substrate 1 for slope protection used in this construction includes:
As shown in FIG. 2, for example, the following configuration is made by using a separately collected cardboard, a corrugated cardboard recycled from used paper, and a sheet 2 obtained by stacking and crimping old newspaper, for example.

That is, the cut forming zone S1 and the cut-free zone S2 are alternately set in the width direction of the paper sheet 2, and the cut a in the sheet width direction is spaced in the longitudinal direction of the sheet 2 in the cut forming zone S1. Are formed substantially parallel to each other, and every other sheet strip portion 2a between the cuts a is bulged to one side and the other side of the sheet, and the bulged portion has an opening for sprouting plant seeds. A is formed.

According to the vegetation substrate 1 having the above structure, the opening A for germinating plant seeds is formed in the paper sheet 2 without punching out a piece of paper, so that there is no waste of resources.
In addition, since the paper sheet 2 has a continuous cut-free zone S2 in the longitudinal direction of the sheet 2, the sheet strip portion 2a is continuous in the sheet width direction. The strength will be kept moderate.

It is to be noted that every other sheet strip 2a is
Swelling on one side and the other side is suitable for forming the vegetation substrate 1 to have a uniform thickness.
a and every other three may be selected and swelled on one side and the other side of the sheet 2, and when the cardboard is selected as the paper sheet 2, the sheet It is possible to swell only about half of the sheet strips 2a to one side of the sheet so as to crush the strips 2a. In other words, the remaining sheet ridges 2a bulge out to the other side of the paper sheet 2.

When the slope N is protected and greened by the vegetation substrate 1 having the above-mentioned structure, if the slope N adapted to the local ecosystem is to be greened by using local buried seeds or flying seeds, The vegetation substrate 1 may be stretched as it is in a bare ground portion or a slope of the slope N, and if the slope N is to be greened at an early stage, it is preferable to sow local plant seeds on the slope N. Or, spray a vegetation base material in which plant seeds are blended with at least one of organic compost, chemical fertilizer, vegetable fiber, water retention agent, soil improvement material, etc. onto the slope N, and cover the slope N. Then, the vegetation base 1 may be stretched, and the vegetation base 1 is appropriately fixed using, for example, an anchor nail or the like.

Alternatively, as shown in FIG. 3, a vegetation base material 3 in which at least one of organic compost, chemical fertilizer, vegetable fiber, water retention agent, soil improvement material, etc. is blended with a plant seed b is used. 4 or a thin cotton-like mat or thin paper or a water-soluble material capable of germinating and growing plant seeds b, as shown in FIG. The vegetation base material 3 is held on the sheet material 4 by a water-soluble glue, and the sheet material 4 is adhered to the back surface of the paper sheet 2. A so-called upholstery body in which the vegetation base material 3 is sandwiched between the sheet materials 4 and 4 is attached to the back surface side of the paper sheet 2, and the vegetation base material 1 is stretched on the slope N as necessary. Polyethylene and biodegradable plastics,
The vegetation substrate 1 may be covered with a net 5 or a wire net made of jute or palm fiber material.

At this time, when the vegetation substrate 1 is stretched on the slope N so that the sheet strip 2a is directed in the contour line direction of the slope N, the opening A for budding due to the swelling of the sheet strip 2a extends in the vertical direction. Since it is open so that the seeds are open, the seeds are suitable for the budding surface of the plant seed b, and there are advantages that the flying seeds can be easily caught and fixed.

Further, since the vegetation substrate 1 is easily bent, the vegetation substrate 1 is easily adapted to the unevenness of the slope N.
Reduces the impact of raindrops, as well as the sheet strip 2a
The swollen portion of the soil has both the function of reducing the speed of the down-flow water and the function of preventing the flow of soil, so that the erosion of the slope surface soil can be effectively prevented. Since the sheet 2 is made of a biodegradable material over the years, the vegetation substrate 1 does not remain on the slope N as a residue, and the natural environment can be favorably maintained.

In the notch forming zone S1, the notches a in the sheet width direction are formed to have a substantially constant length. As shown in FIG. 5, the cuts a having a substantially constant length have a length between them. Is formed partially between adjacent sheet strips 2a, 2a to form a connecting portion 2b extending therebetween, and the sheet strip 2 between the cuts a1, a1 is formed.
a1 may be bulged to the side opposite to the bulging side of the sheet strip portion 2a to form the large-sized sprout opening A and the small-sized sprout opening A1.

At this time, the connecting portion 2b may be formed over three or four adjacent sheet strips 2a, and such connecting portions 2b may be formed every two or three sheets. It may be formed between the ridges 2a. According to the vegetation base 1 having such a configuration, the connecting portion 2b has an effect of further increasing the rigidity of the vegetation base 1.

In each of the above embodiments, the vegetation base 1 is appropriately stretched on the slope N by using, for example, an anchor nail, and then, if necessary, the vegetation base 1 is covered with a net 5 or a wire mesh. However, the vegetation substrate 1 to which the water-soluble sheet material 4 holding the vegetation base material 3 is adhered, as shown in FIG. A greening form in which only the base 1 is stretched on the slope N may be adopted.

[0025]

As described above, according to the vegetation substrate according to the present invention, the opening for germination of plant seeds is formed on a paper sheet without producing any punched paper pieces which are problematic in post-treatment. Is formed, no waste of resources occurs at all, and since there is a continuous cut-free zone in the paper sheet in the longitudinal direction of the sheet, furthermore, the sheet strip is formed in the width direction of the sheet. Since they are continuous, there is no accompanying significant decrease in the tensile strength of the sheet.

Also, since the opening for germination of plant seeds can be oriented in the vertical direction, it is suitable for the germination surface of plant seeds, and has the advantage of easily catching and fixing flying seeds. In addition to being able to easily adapt the substrate to the unevenness of the slope, the vegetation substrate softens the impact of raindrops,
In addition, since the sheet strip has both the function of reducing the velocity of the flowing water and the function of preventing the flow of soil, it is suitable for preventing erosion of the surface soil on the slope.

In addition, since the vegetation substrate is a sheet made of paper and biodegrades, the vegetation substrate does not remain on the slope as a residue, and therefore, the natural environment can be favorably maintained. According to the present invention, there is provided a vegetation substrate suitable for use which exhibits excellent functions in environmental conservation in addition to functions not remaining as residues.
