Description

【0001】
【発明の属する技術分野】
本願発明は、植物材料の裁断茎葉(または裁断地下茎または小球根(以下「裁断茎葉」という))吹付けによる緑化工法に関し、特に裁断茎葉の活着率を大幅に向上させることができ、しかも平地に限らず傾斜地の緑化をも可能にしたものである。
【0002】
【従来の技術】
道路や敷地などに面する法面、河川などに面する堤防法面、さらには敷地などの平地を栄養繁植性植物により緑化する方法として、これまで植生基盤材などと攪拌・混合した植物苗を地盤面上に吹付ける方法が知られている。
【0003】
また、マットやロール状の芝を人力によって張り付ける方法も知られ、この場合、芝の生産現場においては一部「撒芝」と称して、裁断した芝を畑に撒いて芝を育成する方法も行われている。
【0004】
【発明が解決しようとする課題】
しかし、前者の植物苗の吹付けによる緑化工法の場合、植物苗と植生基盤材は機械で混合し吹付けるため、その厚さや植物苗の埋設深さをコントロールするのは非常に困難である。
【0005】
多くの栄養繁殖性植物はセル成型苗として育成し、それを吹付けることによってさほど埋没深さには関係なく良好な活着率を示すが、特に芝に代表される裁断茎葉は植生基盤に適度に埋没していなければ良好な活着は望めない。
【0006】
しかし、機械による吹付け緑化工法の場合、経済性の問題から一般的に植生基盤はさほど厚くないため、地表に露出してしまう苗が多い。
【0007】
経験的にも植物苗を適度な保水力を保持できる位置(埋没深さ)に吹付けられる割合は少なく、そのため乾燥の影響を受けやすく、苗が枯死する等の課題があった。
【0008】
一方、後者の芝の張付けによる緑化工法の場合、いずれも手作業で行われるため効率が悪く、非常に多くの手間暇を必要とし、また当然ながら「撒芝」は平地にしか対応できない等の課題があった。
【0009】
本願発明は、以上の課題を解決するためになされたもので、植物苗の特に芝に代表される裁断茎葉の機械吹付けにおける活着率の向上を図り、しかも平地に限らず、法面の緑化をもきわめて効率的に行えるようにした植物材料の裁断茎葉の吹付けによる緑化工法を提供することを目的とする。
【0010】
【課題を解決するための手段】
請求項1記載の植物材料の裁断茎葉吹付けによる緑化工法は、吹付けた植物材料の裁断茎葉の上に植生基盤材を吹付けることを特徴とするものである。この場合の植物材料の裁断茎葉としては、例えば芝の裁断茎葉の他にアキレア、フィソステギア、ドクダミ、チガヤ、ヨモギ、ササ類(冬期間や早春)の裁断地下茎葉、休眠期のリコリス類(ヒガンバナを含む)、クロッカス、ムスカリ、オキザリス等の小球根を用いることができる。
【0011】
また、植生基盤材は肥沃度が高く植物材料の裁断茎葉が生育できるものであれば特に限定されるものではないが、土壌と主に有機質基材(バーク堆肥、ピートモス等)やファイバー(古紙または木質材等)を混合したもので、現場の状況に応じて厚さを自由に設定できる。
【0012】
また、この場合の植生基盤材は植物材料の裁断茎葉の上に一層に限らず、必要に応じて二層ないし三層、あるいはそれ以上の層に吹付けてもよい。
【0013】
また本願発明は、地盤が岩場などで植物の生育する土壌や肥料分がほとんどない場合、植物材料の裁断茎葉を吹付ける前に下地として植生基盤材を所定の厚さに吹付け、その上に裁断茎葉を吹付けることで、植物の生育環境に適さない場所においても裁断茎葉の活着率を高めることができる。
【0014】
請求項2記載の植物材料の裁断茎葉吹付けによる緑化工法は、請求項1記載の緑化工法において、植物材料の裁断茎葉として芝裁断茎葉を吹付けることを特徴とするものである。
【0015】
請求項3記載の植物材料の裁断茎葉吹付けによる緑化工法は、請求項1または2記載の緑化工法において、ファイバーを吹付けることを特徴とするものである。特に緑化の対象地が法面のような傾斜地で、吹付け直後の裁断茎葉が転がり落ちるおそれがある場合に、植生基盤材にファイバーを混ぜることで密着性が高められて裁断茎葉が転がり落ちるのを阻止することができる。なお、この場合のファイバーとしては例えば古紙や木質材などを用いることができる。
【0016】
また、緑化の対象地が傾斜地の場合、必要に応じて溶接金網やラス金網、あるいはネット類を張り付けることで裁断茎葉と植生基盤材の滑落を防止することができる。
【0017】
また、必要に応じて植生基盤材に植物の種子を追加配合することで、吹付けられた裁断茎葉が根付き、法面が緑化されるまでの間、裸地(土壌面が露出している部分)を極力少なくして雑草の発生を抑えることができる。
【0018】
【発明の実施の形態】
図1(a),(b)は、本願発明の緑化工法によって緑化された法面の一例を示し、図において法面1に植物の裁断茎葉として芝裁断茎葉2が吹付けられ、その上に植生基盤材3が所定の厚さに吹付けられている。
【0019】
そして、時間の経過とともに芝裁断茎葉2が地盤面および植生基盤材3に根付き、生育することで法面1が緑化される。
【0020】
次に、施工方法の一例を順を追って説明する。
▲1▼ 最初に、緑化予定法面に雑草などが生えている場合、除草剤を散布し、刈り払う等して法面の事前処理を行うか、表土を剥ぎ取る。
▲2▼ 次に、表土を剥ぎ取った法面(以下「切土法面1」という)の上に芝裁断茎葉2を吹付ける。この場合、芝裁断茎葉2の吹付けとともに適量の散水を行うものとする。また、切土法面1が岩盤などで肥料分がほとんどないとき、あるいは非常に固いときは、例えば図1(b)に図示するように切土法面1の上に下地として植生基盤材3を所定の厚さに吹付ける。
▲3▼ 次に、芝裁断茎葉2の上に植生基盤材3と同じ植生基盤材4を所定の厚さに吹付ける。その際、植生基盤材4の厚さは、先に吹付けた芝裁断茎葉2が簡単に露出したり乾燥したりしない程度にする。また、厚さにむらが生じないように数回重ねて行うの望ましい。
【0021】
【発明の効果】
この発明は以上説明したとおりであり、特に地盤面に裁断茎葉を吹付け、その上に植生基盤材を吹付ける回数により、裁断茎葉の埋没深さを自由にコントロールすることができる。
【0022】
また、一回の吹付けによって堆積する植生基盤材の厚さが薄い場合でも、複数回の植生基盤材の吹付けにより地表に露出してしまう裁断茎葉を減少させることができ、またそのために乾燥の影響で枯れてしまうものもほとんどなくなる。
【0023】
したがって、吹付けた裁断茎葉の活着率が非常に高くなり、植物裁断茎葉の吹付け緑化をきわめて効率的に行うことができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a revegetation method by spraying cut foliage (or cut rhizomes or small bulbs (hereinafter referred to as “cut foliage”)) of plant material, and in particular, can greatly improve the survival rate of cut foliage and improve the flat ground. Not only is it possible to green slopes.
[0002]
[Prior art]
As a method of greening slopes facing roads and sites, embankments facing rivers, and flats such as sites with vegetatively vegetative plants, plant seedlings that have been stirred and mixed with vegetation base materials have been used up to now. Is sprayed onto the ground surface.
[0003]
Also known is a method of pasting mats or rolls of turf by human power.In this case, at the turf production site, a method called scattered turf is used to cultivate turf by cutting and cutting turf. Has also been done.
[0004]
[Problems to be solved by the invention]
However, in the case of the former revegetation method by spraying plant seedlings, since the plant seedlings and the vegetation base material are mixed and sprayed by a machine, it is very difficult to control the thickness and the burial depth of the plant seedlings.
[0005]
Many vegetatively propagated plants are grown as cell-molded seedlings, and when sprayed, show a good survival rate regardless of the burial depth.However, cut foliage such as turf is suitable for vegetation bases. If not buried, good survival cannot be expected.
[0006]
However, in the case of the mechanical spraying greening method, since the vegetation base is generally not so thick due to economical problems, many seedlings are exposed on the ground surface.
[0007]
Empirically, the rate at which plant seedlings are sprayed at a position (burial depth) where a proper water retention capacity can be maintained is low, and therefore, there is a problem that the seedlings are easily affected by drying and the seedlings die.
[0008]
On the other hand, in the latter case, the greening method by sticking turf is inefficient because it is performed manually, and requires a lot of time and labor. There were challenges.
[0009]
The present invention has been made in order to solve the above-described problems, and aims to improve the survival rate in mechanical spraying of plant seedlings, particularly cutting stems and leaves typified by turf. It is an object of the present invention to provide a greening method by spraying cut foliage of plant material, which is capable of extremely efficiently performing planting.
[0010]
[Means for Solving the Problems]
The planting method according to the first aspect of the present invention, wherein the plant material is sprayed with cut stems and leaves, is characterized in that a vegetation base material is sprayed on the cut stems and leaves of the sprayed plant material. In this case, the cutting stems and leaves of the plant material include, for example, cutting stems and leaves of turf, cutting subterranean stems and leaves of lycoris (higanbana), cuttings of Achillea, physostegea, dokudami, chigaya, mugwort, sasa (winter season and early spring). ), Crocus, muscari, oxalis and the like.
[0011]
The vegetation base material is not particularly limited as long as it has a high fertility and can grow cut stems and leaves of the plant material. However, soil and mainly organic base materials (such as bark compost and peat moss) and fibers (waste paper or Wood material), and the thickness can be set freely according to the situation at the site.
[0012]
In this case, the vegetation base material is not limited to a single layer on the cut foliage of the plant material, but may be sprayed on two or three or more layers as necessary.
[0013]
Further, the invention of the present application, when there is almost no soil or fertilizer component where the plant grows on the rocky ground or the like, before spraying the cut foliage of the plant material, spraying the vegetation base material to a predetermined thickness as a groundwork, By spraying the cut foliage, the survival rate of the cut foliage can be increased even in a place that is not suitable for the growth environment of the plant.
[0014]
According to a second aspect of the present invention, there is provided a greening method by spraying cut stems and leaves of a plant material, wherein turf cut stems and leaves are sprayed as cut stems and leaves of the plant material.
[0015]
According to a third aspect of the present invention, there is provided a tree planting method according to the first or second embodiment, wherein fibers are sprayed. In particular, when the target area for greening is a slope such as a slope, and there is a risk that the cut stems and leaves immediately after spraying may fall down, mixing fibers with the vegetation base material increases the adhesion and the cut stems and leaves roll down. Can be prevented. In this case, as the fiber, for example, waste paper or wood material can be used.
[0016]
Further, when the target site for greening is a sloped land, a cut wire and a vegetation base material can be prevented from slipping off by attaching a welding wire net, a lath wire net, or nets as necessary.
[0017]
In addition, by adding plant seeds to the vegetation base material as necessary, the sprayed cut stems and roots take root, and until the slope is greened, the bare land (the part where the soil surface is exposed) ) Can be reduced as much as possible to suppress the occurrence of weeds.
[0018]
BEST MODE FOR CARRYING OUT THE INVENTION
FIGS. 1 (a) and 1 (b) show an example of a slope that has been greened by the greening method of the present invention. In the figure, lawn cutting foliage 2 is sprayed on the slope 1 as cutting foliage of a plant. The vegetation base material 3 is sprayed to a predetermined thickness.
[0019]
Then, as the time elapses, the turf cutting stem leaves 2 are rooted on the ground surface and the vegetation base material 3 and grow, whereby the slope 1 is greened.
[0020]
Next, an example of a construction method will be described step by step.
(1) First, when weeds and the like are growing on the slope to be revegetated, apply a herbicide and cut off the grass to perform pretreatment on the slope, or peel off the topsoil.
{Circle over (2)} Next, turf cutting foliage 2 is sprayed on the slope from which the topsoil has been stripped (hereinafter referred to as “cut slope 1”). In this case, an appropriate amount of watering is performed together with the spraying of the turf cutting stems 2. Also, when the cut slope 1 is a bedrock or the like and hardly contains any fertilizer, or is very hard, for example, as shown in FIG. Is sprayed to a predetermined thickness.
{Circle around (3)} Next, the same vegetation base material 4 as the vegetation base material 3 is sprayed on the cut turf foliage 2 to a predetermined thickness. At this time, the thickness of the vegetation base material 4 is set to such a degree that the previously cut turf cutting foliage 2 is not easily exposed or dried. In addition, it is desirable to perform the operation several times so that the thickness is not uneven.
[0021]
【The invention's effect】
The present invention is as described above. In particular, the burial depth of the cut foliage can be freely controlled by spraying the cut foliage on the ground surface and spraying the vegetation base material thereon.
[0022]
In addition, even when the thickness of the vegetation base material deposited by a single spray is thin, the number of cut foliage exposed on the ground surface by multiple sprays of the vegetation base material can be reduced, and as a result, drying Almost nothing that withers due to the effects of the weather.
[0023]
Therefore, the survival rate of the sprayed cut leaves becomes extremely high, and the sprayed greening of the cut plant leaves can be performed very efficiently.
