【発明の詳細な説明】 この発明は、木本を発芽生育させる植生筒を法面に配置
した植生袋に打込み、法面に育生した草本中に木本を育
生させる緑化工法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a greening method in which a vegetation tube for germination and growth of woody plants is placed in a vegetation bag placed on a slope, and woody plants are grown among the grass growing on the slope.

今まで、草本種子を蒔いた植生袋に木本種子を同時に蒔
いて法面の草本中に木本を保護育生させる技術は確立し
ていない。Until now, no technology has been established to protect and grow woody plants among the grassy plants on a slope by simultaneously sowing woody seeds in a vegetation bag in which herbaceous seeds have been sown.

このため、地山法面などを緑化するに当っては、草本の
種子を蒔いて草本を生育させ、その後に木本苗を植えて
生育を図る必要があり、草本と木本とを混生じて緑化を
図るには多大の工数を必要とした。Therefore, when greening slopes of the ground, it is necessary to sow herbaceous seeds and allow the herbaceous plants to grow, and then to plant and grow woody seedlings, resulting in a mixture of herbaceous and woody plants. A large amount of man-hours were required to achieve greening.

この発明は上記の問題点に着目してなされたものである
。This invention was made by paying attention to the above-mentioned problems.

その目的は、植生袋と植生筒により草本の種子と木本の
種子を同時に蒔いて草本が植生した土地に草本の根層の
下層部に木本種干る位置せしめて発芽生育を図るにある
。The purpose is to sow herbaceous seeds and woody seeds at the same time using vegetation bags and vegetation tubes, and to position the woody seeds in the lower layer of the herbaceous root layer in the herbaceous-vegetated land so that they can germinate and grow. .

。The gist of this invention is to create a vegetation tube by filling woody seeds and soil into a shell made of easily collapsible material with an open bottom end, a large number of through holes in the side wall, and a tapered bottom end. The vegetation tubes are placed uniformly on the slope and driven into the required locations of a vegetation bag filled with herb seeds and soil. This is a greening method that allows seeds inserted into the cylinder to germinate and grow inside the cylinder, which is isolated from the surrounding herbaceous root layer, thereby creating a simultaneous coexistence of herbaceous and woody plants.

以下実施例を図面を用いて説明する。Examples will be described below with reference to the drawings.

第１図は植生筒６を示すもので、その外筒１は土下端が
開口し、下端部が先細り状となっていてその側壁に筒内
外へ連通した多数の透孔２を穿設した筒状のものである
。Figure 1 shows a vegetation tube 6, the outer tube 1 of which is open at the bottom end, tapered at the lower end, and has a number of through holes 2 in its side wall that communicate with the inside and outside of the tube. It is in the form of

この外筒１内に木本種子３、土壌４、および保湿材５が
充填されて植生筒６が作られる。This outer cylinder 1 is filled with woody seeds 3, soil 4, and moisturizing material 5 to form a vegetation cylinder 6.

前記外筒１は、紙、腐食質物質、繊維、竹、木材等の分
解崩壊する性質をもった易崩壊性物質より作られ、土壌
中には必要に応じ肥料および保湿材が添加されるもので
ある。The outer cylinder 1 is made of easily disintegrating materials such as paper, corrosive substances, fibers, bamboo, wood, etc., and fertilizers and moisturizing materials are added to the soil as necessary. It is.

第２図に示すように法面７に一様に植生袋９を配置し、
次に植生袋９に間隔をおいて必要数の植生筒６を打込む
。As shown in FIG. 2, vegetation bags 9 are placed uniformly on the slope 7,
Next, a required number of vegetation tubes 6 are inserted into the vegetation bag 9 at intervals.

植生袋９は、麻、綿、化学繊維、合成繊維等の粗目織物
より作られ、袋内部に草本種子８およぴ生育用の土壌４
が充填されている。The vegetation bag 9 is made of coarse fabric such as hemp, cotton, chemical fiber, or synthetic fiber, and contains herbaceous seeds 8 and soil 4 for growing inside the bag.
is filled.

なお植生筒６を打込んだ位置に案内棒を立てるならば木
本種子位置を明示するとともに、木本生育時の支えとす
ることができるので便利である。If a guide rod is erected at the position where the vegetation tube 6 is driven, it is convenient because it can clearly indicate the location of woody seeds and can also be used as a support during the growth of woody plants.

この緑化工法は上記のごとく草本種子と木本種子を同時
に蒔いて発芽生育し混生を図ることができる。As mentioned above, this greening method allows herbaceous seeds and woody seeds to be sown at the same time, allowing them to germinate and grow, resulting in mixed growth.

これは外簡によって草本の根層と木本の根層とが隔離し
ているためで、種子が発芽すると茎は上端開口部より立
上り根は外筒内で生育し草本の根によって阻害されるこ
とはない。This is because the herb root layer and the woody root layer are separated by the outer tube, and when the seed germinates, the stem rises from the upper opening and the roots grow inside the outer tube and are inhibited by the herb roots. Never.

木本が生長するに伴ない根は外筒下端開口より土壌中に
真直ぐに伸長し、あるいは外筒透孔より植生袋の土壌中
を経て伸長し、次第に草本根層と土壌中で共存し、草本
と木本は安定した混生状態となる。As the woody plant grows, the roots extend straight into the soil through the opening at the bottom of the outer cylinder, or through the holes in the outer cylinder through the soil of the vegetation bag, and gradually coexist with the herbaceous root layer in the soil. Herbaceous and woody plants form a stable intergrowth.

′外筒は分解崩壊したり、破壊されたりし、木本が大き
く生成するのを阻害しない。'The outer cylinder decomposes, collapses, or is destroyed, and does not inhibit the growth of large woody plants.

なお、木本種子は外筒１内に入っているので、地面に直
接蒔く場合に比べ、動物により喰べられる機会も少なく
、喰害防止の上でも効果がある。In addition, since the woody seeds are contained in the outer cylinder 1, there is less chance of them being eaten by animals compared to when they are sown directly on the ground, which is also effective in preventing damage from being eaten.

この発明は以上の通りであって、次の効果をもたらす。The present invention is as described above, and brings about the following effects.

■植生筒を法面に配置した植生袋に打込むことにより草
本と木本を同時に種子を蒔いて法面の混生緑化を図るこ
とができ、■植生袋と植生筒とを使用するから工期を短
縮し、施工コストを低減することができる。■ By driving vegetation tubes into vegetation bags placed on slopes, it is possible to sow herbaceous and woody seeds at the same time and achieve mixed greening of slopes. ■ Using vegetation bags and vegetation tubes reduces construction time. It is possible to shorten the construction time and reduce construction costs.

■木本種子は動物にょる喰害の防止ができ、木本は草本
により生育に必要な湿度が医たれ充分成長する迄草本よ
り隔離することができる。■ Woody seeds can be prevented from being eaten by animals, and woody plants can be isolated from herbaceous plants until they have sufficient humidity to grow.
