Time to disassemble It will help.
  • the fertilizer located on the outer side is decomposed as soon as the biodegradable plastic decomposes. Ingredients act, but the inside is hardened with biodegradable plastic, so the biodegradable plastic that surrounds the organic fertilizer particles in the vicinity of the inside of the inside is in the vicinity of the center until it is sequentially decomposed.

In fact, organic fertilizer components kneaded into biodegradable plastics are practically made as biodegradable plastics because each organic fertilizer particle is substantially covered and hardened with biodegradable plastics. Even if a biodegradable plastic that can be biodegraded in a relatively short time is used, the biodegradable plastic film that covers the fertilizer is decomposed and the fertilizer is exposed. Time to disassemble It will help. Even if a biodegradable plastic that biodegrades in a relatively short period of time is used as the outer biodegradable plastic, the fertilizer located on the outer side is decomposed as soon as the biodegradable plastic decomposes. Ingredients act, but the inside is hardened with biodegradable plastic, so the biodegradable plastic that surrounds the organic fertilizer particles in the vicinity of the inside of the inside is in the vicinity of the center until it is sequentially decomposed. The fertilizer that exists in the vicinity does not function as a fertilizer, and there is a problem that it takes too much time for the fertilizer in the vicinity of the inner center to act effectively as a fertilizer. Also, depending on the type of fertilizer, in order to make the desired time for the fertilizer to start working effectively, by selecting the type of biodegradable plastic that has a decomposition rate commensurate with the fertilizer used, There are so many grades of biodegradable plastics with different biodegradability periods on the market, even if the biodegradability plastics are selected appropriately by selecting the biodegradation period of the coconut resin constituting the outer layer and the central layer. Therefore, depending on the purpose of use, the type and grade of biodegradable plastic should be used to control the rate of biodegradation, and the degree of action of fertilizer should be relatively freely designed according to the purpose of use. Has its limits.
[0004] そして前記特許文献 1には、生分解性プラスチックとして、ポリ乳酸を使用することも 一応列挙されているが、現実には、ポリ乳酸を生分解性プラスチックとして使用して 前記特許文献 1の如くポリ乳酸と有機肥料とを混合したものを加熱溶融成型しようと すると、 170°C近傍に加熱する必要があるので、有機肥料成分が熱によって分解さ れてしまうものが多ぐまた、本発明の如ぐ有機肥料以外にも各種薬剤を用いようと する場合には、加熱溶融成型の熱によって分解されてしまい当該薬剤の機能が発揮 できなくなるものも多々ある。従って現実には、ポリ乳酸を生分解性プラスチックとして 用いた力かる有機肥料成型物は商品化されておらず、現実には高い温度で成型す る必要のな ヽポバールを生分解性榭脂として用いたパイル型有機肥料が商品化さ れているに過ぎない。  [0004] And, Patent Document 1 also enumerates the use of polylactic acid as a biodegradable plastic, but in reality, the above-mentioned Patent Document 1 uses polylactic acid as a biodegradable plastic. If a mixture of polylactic acid and organic fertilizer is heated and melt-molded as described above, it must be heated to around 170 ° C, so many organic fertilizer components are decomposed by heat. In addition to organic fertilizers as in the invention, when various drugs are to be used, there are many that are decomposed by the heat of hot melt molding and cannot function. Therefore, in reality, powerful organic fertilizer moldings using polylactic acid as a biodegradable plastic have not been commercialized, and in reality it is necessary to mold at high temperatures. The pile-type organic fertilizer used is only commercialized.
[0005] しかし、ポバールを生分解性榭脂として用いた場合、スティック表層部には、有機肥 料粒子が存在するので、スティック打ち込み後カビが発生しやす 、などの問題があつ た。  [0005] However, when poval is used as a biodegradable resin, organic fertilizer particles are present on the surface of the stick, so that there are problems such as the occurrence of mold after stick sticking.
[0006] 本発明は、これらの問題を解決し、植物育成又は保護用柱状体を土壌に差し込ん だ時から、肥料その他の植物の育成ないし保護用薬剤の薬剤作用が発揮され、しか も、その作用量や作用時間を目的に応じて変えたものを容易に提供でき、使用した 際にカビが発生しにくい植物育成又は保護用柱状体を提供することを目的とするも のである。 [0006] The present invention solves these problems and inserts a columnar body for plant growth or protection into soil. From that time, the chemical action of fertilizers and other plant growth or protection agents was demonstrated, but it was possible to easily provide the action amount and action time according to the purpose, and mold would be generated when used. It is intended to provide a columnar body for plant growth or protection that is unlikely to occur.

In this example, the hollow columnar body is provided on the side wall surface on the lower side of the hollow cylindrical body main body portion 3 .
[0044] 次に、図 6は図 1で示した態様の中空柱状体の側壁面外側に、ポリ乳酸からなる抜 け防止用突起 10が更に形成されている中空柱状体の実施形態の一例である。  Next, FIG. 6 is an example of an embodiment of the hollow columnar body in which the extraction preventing projection 10 made of polylactic acid is further formed on the outside of the side wall surface of the hollow columnar body of the embodiment shown in FIG. is there.
[0045] 図 6の実施形態では抜け防止用突起 10は、略板状の略変形楔状の抜け防止用突 起であり、その上面は中空柱状体の長さ方向に対し垂直方向に水平ではなぐ斜め 上向きになる面で構成され、且つ、当該上面の外側稜 10aの長さが、当該上面の中 空柱状体側壁へのつけ根部分の稜 10bよりも大きぐ上面の外脇側 10cに少し厚み を持たせたタイプの略楔状の抜け防止用突起である。  [0045] In the embodiment of Fig. 6, the removal preventing projection 10 is a substantially plate-like, substantially deformed wedge-shaped projection for preventing removal, and the upper surface thereof is not horizontally horizontal to the length direction of the hollow columnar body. Slightly thicker on the outer side 10c of the upper surface, which is composed of a diagonally upward surface, and the length of the outer ridge 10a of the upper surface is larger than the ridge 10b of the root portion of the upper column on the side wall of the hollow columnar body This is a substantially wedge-shaped projection for preventing slipping.
[0046] この態様では、中空柱状体の側壁面の左右に設けられた抜け防止用突起 10の設 けられている位置について、中空柱状体の長さ方向(上下方向)での位置は、左右と もほぼ同じで、中空円柱状体本体部分 3の上方側の側壁面にそれぞれ設けられてい る例を示した。  [0046] In this aspect, the positions in the length direction (vertical direction) of the hollow columnar body are the left and right positions of the positions at which the protrusions 10 for preventing removal provided on the left and right of the side wall surface of the hollow columnar body are provided. The examples are the same as those shown in FIG. 1 and are provided on the upper side wall surfaces of the hollow cylindrical body part 3 respectively.
[0047] 次に、図 7は図 2で示した態様の中空柱状体の側壁面外側に、ポリ乳酸からなる抜 け防止用突起 11が更に形成されて 、る中空柱状体の実施形態の一例である。  Next, FIG. 7 shows an example of the embodiment of the hollow columnar body, in which the extraction preventing projection 11 made of polylactic acid is further formed on the outside of the side wall surface of the hollow columnar body of the embodiment shown in FIG. It is.
[0048] 図 7の実施形態では抜け防止用突起 11は、板状で略楔状の抜け防止用突起では あるが、図 4に示した抜け防止用突起 8に比べて、抜け防止用突起の下外側部分が やや緩やかに外側凸にカーブしている抜け防止用突起を設けた例を示した。中空柱 状体 1の側壁面の左右外側に、且つそのうちの一方(図 7で左側)の抜け防止用突起 は中空柱状体 1の中空円柱状体本体部分 3の上方側の側壁面に、他方(図 7で右側 )の抜け防止用突起は中空柱状体 1の中空円柱状体本体部分 3の下方側の側壁面 に設けられて 、る例である。  [0048] In the embodiment of FIG. 7, the drop prevention protrusion 11 is a plate-like, substantially wedge-shaped drop prevention protrusion, but is lower than the drop prevention protrusion 8 shown in FIG. An example is shown in which a protrusion for preventing slipping is provided in which the outer portion is slightly gently curved outward. The left and right outer sides of the side wall surface of the hollow columnar body 1 and one of them (on the left side in FIG. 7) has a protrusion for preventing slipping on the side wall surface on the upper side of the hollow cylindrical body portion 3 of the hollow columnar body 1 and the other side. In this example, the protrusion for preventing slipping (on the right side in FIG. 7) is provided on the side wall surface on the lower side of the hollow columnar body portion 3 of the hollow columnar body 1.
[0049] 以上に示したポリ乳酸力 なる抜け防止用突起は上記の図 4〜7に示した具体的態 様例に限定されるものではなぐ本発明の目的を阻害するものでない限り、抜け防止 用突起は 1個でも、 3個以上設けてもよぐ抜け防止用突起の形状も中空柱状体を土 に差込む際に差し込めないなどの不都合が生じないような形状でない限り、且つ、土 に差込んだ後は抜け防止機能を有する形状であれば特に制限はなが、土に差込み やすぐ土に差込んだ後は抜け防止機能を発揮しやすいと言う観点力 は、後述す る図 8や図 9で示す棒状の抜け防止用突起を除いて、通常は、抜け防止用突起の上 方部分は下方部分に比べて、長手方向(長手方向とは中空柱状体の長手方向基準 )に対し垂直な方向の断面積が大きいものが好ましぐ更には下方側方向に次第に 断面積が小さくなる形状のものがより好ましい形状である。また、図 4〜図 7に具体的 に図示した態様は、図 1、図 2に示した態様の中空柱状体に抜け防止用突起が更に 形成されている実施形態例を示したが、図 3に示した態様の中空柱状体に抜け防止 用突起が更に形成されて 、てもよ 、ことは勿論である。 [0049] The above-described protrusion for preventing omission as polylactic acid is not limited to the specific embodiments shown in Figs. 4 to 7 described above, and is not used unless it obstructs the object of the present invention. Even if there are one or more protrusions, the shape of the protrusions to prevent slipping out is not a shape that does not cause inconvenience such as being unable to be inserted when inserting the hollow columnar body into the soil, and There is no particular limitation as long as the shape has a function of preventing slipping out after insertion, but the ability to easily exert the function of preventing slipping out after being inserted into the soil or immediately after being inserted into the soil is shown in Fig. 8 described later. Except for the rod-shaped removal prevention protrusions shown in Fig. 9 ordinarily, the upper part of the removal prevention protrusions is usually longer than the lower part (the longitudinal direction is the longitudinal reference of the hollow columnar body). A shape having a large cross-sectional area in the vertical direction is preferred, and a shape having a cross-sectional area that gradually decreases in the downward direction is a more preferred shape. Further, the embodiment specifically shown in FIGS. 4 to 7 shows an embodiment in which the hollow columnar body of the embodiment shown in FIGS. Needless to say, the hollow columnar body of the embodiment shown above may be further provided with protrusions for preventing the removal.
[0050] また、抜け防止用突起を 2つ以上有する態様の場合、中空柱状体の長手方向に対 し垂直な断面を仮定した場合、抜け防止用突起は、中空柱状体を中心軸としてその 周りに必ずしも均等の角度で間隔を置いて形成されている必要はなぐ適宜不均等 な間隔で設けてもよいし、中空柱状体の長さ方向(上下方向)で抜け防止用突起を 設ける位置も本発明の目的が達成される限り特に限定はない。  [0050] Further, in the case of an embodiment having two or more removal prevention protrusions, assuming a cross section perpendicular to the longitudinal direction of the hollow columnar body, the removal prevention protrusions have the hollow columnar body as a central axis. It is not always necessary to form the gaps at equal angles, and the gaps may be provided at irregular intervals as appropriate. Also, the positions of the protrusions for preventing slipping in the length direction (vertical direction) of the hollow columnar body are also present. There is no particular limitation as long as the object of the invention is achieved.
[0051] 尚、抜け防止用突起の数は 1つでもよいし、 3つ以上でもよいが、 2つがコストの面、 2つで十分抜け防止機能が発揮できることから最も好ましい。  [0051] The number of protrusions for preventing slipping may be one, or three or more, but two is the most preferable because two are cost effective and two can sufficiently exhibit the function of preventing slipping.
[0052] 抜け防止用突起を設けた中空柱状体は、また法面などに芝などを植え付ける場合 には、芝の複数本を集めてある程度の大きさのマット状にした芝生マットが用いられる 力 芝がまだ当該法面に根が伸びていない状態なので、法面に芝生マットなどを固 定し、風や雨などで当該法面に植え付けた芝生マットが剥がれてしまうことを防止す る上でも、抜け防止用突起を設けた中空柱状体を植え付ける芝生マット面に差し込 んで法面の土に芝生マットを固定することもでき好ましく用いられる。このような状況 で抜け防止用突起を設けた中空柱状体を用いる場合には、抜け防止用突起の少な くとも 1つは、中空柱状体の長さ方向の上方部分に設けられているものが好ましい。 同様に、土の法面を植物で保護ないし緑の景観にするために、織物、編物、不織布 、ネット状物、ヤシの繊維のマットなどの天然の繊維状物を用いたマットなどに植物の 種や、自然に当該法面に飛んできた植物の種を育成するための肥料などを固着した いわゆる植生シートとか植生マットなどを法面に固定する場合にも本発明の抜け防止 用突起を設けた植物育成又は保護用柱状体は有効に用いることができる。また、必 ずしも法面に限られず、比較的平坦な地形を有していても、特に風などの強い地域 に上述したような芝生マット、植生シート、植生マットなどを固定する場合にも本発明 の抜け防止用突起を設けた植物育成又は保護用柱状体は有効に用いることができ る。 [0052] The hollow columnar body provided with the protrusions for preventing slipping is also used when a lawn mat having a certain size is collected by collecting a plurality of lawns when planting turf or the like on a slope. Since the turf is not yet rooted on the slope, the lawn mat is fixed to the slope and the lawn mat planted on the slope is prevented from being peeled off by wind or rain. The lawn mat can be fixed to the sloped soil by inserting it into a lawn mat surface on which a hollow columnar body provided with protrusions for preventing slippage is planted. In this situation, when using a hollow columnar body provided with a protrusion for preventing slipping, at least one of the protrusions for preventing slipping is provided at an upper portion in the length direction of the hollow columnar body. preferable. Similarly, in order to protect the soil slope with plants or to make it a green landscape, the plant is applied to mats using natural fibrous materials such as woven fabrics, knitted fabrics, nonwoven fabrics, nets, and palm fiber mats. Protrusion for preventing omission of the present invention is also provided when fixing a so-called vegetation sheet or vegetation mat to which a seed or a fertilizer for growing a seed of a plant that naturally flies to the slope is fixed. The plant growth or protection columnar body can be used effectively. In addition, it is not necessarily limited to slopes, and even when it has a relatively flat terrain, especially when fixing lawn mats, vegetation sheets, vegetation mats, etc. as described above to windy areas. The columnar body for plant growth or protection provided with the protrusion for preventing omission of the present invention can be used effectively.
[0053] 次に、図 8と図 9に押さえ用突起と抜け防止用突起が更に形成されている本発明の 中空柱状体の少数の具体例の斜視図を示した。  Next, FIG. 8 and FIG. 9 show perspective views of a few specific examples of the hollow columnar body of the present invention in which a pressing protrusion and a drop prevention protrusion are further formed.
[0054] 図 8は図 2で示したような態様の中空柱状体 1の側壁面外側の上端近傍に、ポリ乳 酸からなる押さえ用突起 21が更に形成され、且つ、前記押さえ用突起 21より下方で 、前記中空柱状体 1の側壁面外側に、ポリ乳酸力もなる抜け防止用突起 12が更に形 成されて!/ヽる中空柱状体の実施形態の一例である。  In FIG. 8, a pressing protrusion 21 made of polylactic acid is further formed in the vicinity of the upper end on the outside of the side wall surface of the hollow columnar body 1 having the form shown in FIG. Below is an example of an embodiment of a hollow columnar body in which a protrusion 12 for preventing slippage that also has a polylactic acid force is further formed on the outside of the side wall surface of the hollow columnar body 1.
[0055] この態様では、中空柱状体 1の側壁面外側の上端近傍からほぼ横方向に張り出す 、ポリ乳酸力もなる押さえ用突起 21が左右に 2個形成されている。この押さえ用突起 21はほぼ板状の押さえ用突起で中空柱状体 1の側壁面外側の上端より若干下方か らほぼ横方向に張り出している。押さえ用突起は上面、下面とも必ずしも平滑面であ る必要はなぐ芝生マットなどの天然植物の集合体力 なるマットや、植生シート、植 生マットなどの上面を押える機能が発揮できるか、或!、は保護用ネットのストランドな どを引っ掛けて押える機能が発揮できればよぐ本発明の目的が達成できる限り、粗 面や凹凸面とすることは任意である。また、押さえ用突起 21の張り出し方向は、図示 したこの態様のものでは、ほぼ水平方向である力 押さえ用突起 21の少なくとも下側 面において、その先端が若干斜め下方向になる様に少なくとも下側面が斜めに傾斜 した方向でも良い。芝生マットなどの天然植物の集合体力もなるマットや、植生シート 、植生マットなどの上面を押える機能が発揮できる力 或いは保護用ネットのストラン ドなどを引っ掛けて押える機能が発揮できれば押さえ用突起 21の張り出し方向は適 宜変更可能である。また、この例では、押さえ用突起 21は、中空柱状体 1の側壁面 外側の上端より若干下方に設けられているが、中空柱状体 1の側壁面外側の上端か ら横方向に張り出していても良い。更にまた、この例では、押さえ用突起 21は 2個設 けられた態様を示しているが、実質上、上述のような押え機能が発揮される限り 1個で も良いし、 3個以上としても良い。尚、図 8に示した中空柱状体の態様は、抜け防止用 突起 12が中空柱状体 1の側壁面の左右外側に、且つそのうちの一方(図 8で左側) の抜け防止用突起は中空柱状体 1の中空円柱状体本体部分 3の上端部より下側で あるが、中空円柱状体本体部分 3の上方側の側壁面に、他方(図 8で右側)の抜け防 止用突起は中空柱状体 1の中空円柱状体本体部分 3の下方側の側壁面に設けられ ている。この抜け防止用突起 12は、細めの棒状で先端 12aの厚さが薄くなつた形状 の抜け防止用突起であり、中空円柱状体本体部分 3の長さ方向に対し、斜め上に開 V、て 、るような角度で設けられて 、る。抜け防止用突起はこの様に細めの棒状とする と、植物の根などを傷める割合が少なく好ましい。 [0055] In this embodiment, two pressing protrusions 21 having a polylactic acid force are formed on the left and right sides, which protrude substantially laterally from the vicinity of the upper end outside the side wall surface of the hollow columnar body 1. The pressing protrusion 21 is a substantially plate-shaped pressing protrusion that protrudes in a substantially lateral direction from slightly below the upper end on the outer side of the side wall surface of the hollow columnar body 1. The pressing protrusions need not be smooth on both the upper and lower surfaces, and can function to hold the upper surface of natural plants such as lawn mats, vegetation sheets, vegetation mats, etc. As long as the object of the present invention can be achieved as long as the function of hooking and pressing the strand of the protective net can be exerted, it is optional to make the surface rough or uneven. In addition, the protruding direction of the pressing protrusion 21 is at least the lower surface so that the tip of the pressing protrusion 21 is slightly inclined downward in at least the lower surface of the force pressing protrusion 21 that is substantially horizontal in the illustrated embodiment. The direction of slanting may be used. The mating force of a natural plant such as a lawn mat, the ability to exert the function of pressing the top surface of a vegetation sheet, a vegetation mat, or the function of holding a protective net strand, etc. The overhang direction can be changed as appropriate. In this example, the pressing protrusion 21 is provided slightly below the upper end on the outer side of the side wall surface of the hollow columnar body 1. It may be overhanging laterally. Furthermore, in this example, two pressing protrusions 21 are shown. However, as long as the presser function as described above is substantially exhibited, one may be used, or three or more. Also good. In the embodiment of the hollow columnar body shown in FIG. 8, the protrusion 12 for preventing slippage is formed on the left and right outer sides of the side wall surface of the hollow columnar body 1 and one of the protrusions for preventing slipping (left side in FIG. 8) is hollow columnar. The hollow columnar body part 3 of the body 1 is below the upper end of the hollow cylindrical body part 3, but the other side (on the right side in FIG. 8) protrusion prevention protrusion is hollow on the upper side wall surface of the hollow cylindrical body part 3 The columnar body 1 is provided on the side wall surface on the lower side of the hollow cylindrical body portion 3. This removal prevention protrusion 12 is a thin prevention rod-like protrusion with a thin tip 12a, and is open obliquely upward with respect to the length direction of the hollow cylindrical body part 3. It is provided at such an angle. It is preferable to make the protrusions for preventing slipping in such a thin rod shape because the ratio of damaging the roots of plants is small.
[0056] この実施形態例の様に、押さえ用突起と抜け防止用突起を設けた中空柱状体は、 例えば、法面などに芝などを植え付ける場合には、法面に芝生マットなどを固定し、 風や雨などで当該法面に植え付けた芝生マットが剥がれてしまうことを防止する機能 が極めて優れている。押さえ用突起と抜け防止用突起を設けた中空柱状体を、芝生 マットのおもて面力 差し込んで法面の土に芝生マットを固定すると、風などの力で マットが地面力 浮き上がろうとするのを押さえ用突起で押える機能が十分発揮され 、且つ、地面に打ち込まれた当該植物育成又は保護用柱状体が風などの力で芝生 マットと共に抜けるのを抜け防止用突起で防止できるので、芝生マットや植生シート、 植生マットなどを固定する機能が一層強化され、植物保護用ネットなどを固定する場 合にも、極めて有効に使用できる。  [0056] As in this embodiment, the hollow columnar body provided with the pressing protrusion and the removal preventing protrusion has a lawn mat or the like fixed to the slope when planting grass or the like on the slope, for example. The function of preventing the grass mat planted on the slope from being peeled off by wind or rain is extremely excellent. Inserting a hollow columnar body with a holding protrusion and a slip-off prevention protrusion into the surface of the lawn mat and fixing the lawn mat to the sloped soil will cause the mat to lift the ground force with the force of the wind. The function of pressing down with the pressing protrusion is sufficiently exerted, and the plant-growing or protective columnar body driven into the ground can be prevented from coming off with the lawn mat by the force of the wind, etc. The function of fixing lawn mats, vegetation sheets, vegetation mats, etc. is further strengthened, and it can be used extremely effectively when fixing plant protection nets.
[0057] また、必ずしも法面に限られず、比較的平坦な地形を有して!/、ても、特に風などの 強い地域に上述したような芝生マット、植生シート、植生マットなどを固定する場合に も本発明の押さえ用突起が少なくとも設けられた植物育成又は保護用柱状体は有効 に用いることができる。  [0057] Further, the terrain mat, vegetation sheet, vegetation mat, etc. as described above are fixed to a strong windy area especially with a relatively flat terrain! Even in this case, the plant growth or protection columnar body provided with at least the pressing protrusion of the present invention can be used effectively.
[0058] 次に図 9は図 1で示したような態様の中空柱状体 1の側壁面外側の上端近傍に、ポ リ乳酸力 なる押さえ用突起 22が更に形成され、且つ、前記押さえ用突起 22より下 方で、前記中空柱状体 1の側壁面外側に、ポリ乳酸からなる抜け防止用突起 13が更 に形成されて ヽる中空柱状体の実施形態の一例である。 Next, FIG. 9 shows that a pressing protrusion 22 having a polylactic acid force is further formed in the vicinity of the upper end on the outside of the side wall surface of the hollow columnar body 1 having the embodiment shown in FIG. The protrusion 13 for preventing slipping made of polylactic acid is further provided on the outside of the side wall surface of the hollow columnar body 1 below 22. 1 is an example of an embodiment of a hollow columnar body formed in

The pressing protrusion 22 is a substantially disk-shaped pressing protrusion having a circular hole in the center, and slightly protrudes from the upper end outside the side wall surface of the hollow columnar body 1 in a substantially lateral direction. The upper and lower surfaces of the pressing protrusions do not necessarily have to be smooth surfaces. It can function to hold the upper surface of vegetation sheets, vegetation mats, etc. As long as the object of the present invention can be achieved as long as the function of hooking and pressing the strands can be exerted, it is arbitrary to make the surface rough or uneven. Further, the protruding direction of the pressing protrusion 22 is substantially horizontal in this embodiment shown in the figure, but at least the lower surface of the pressing protrusion 22 is at least the lower side so that the tip is slightly inclined downward. Even in a slanted direction, Protrusions for pressing if the function of pressing the upper surface of the mat, such as a lawn mat, or the vegetation sheet, the vegetation mat, etc. The overhanging direction of 22 can be changed as appropriate. Further, in this example, the pressing projection 22 is provided slightly below the upper end outside the side wall surface of the hollow columnar body 1 Even if the upper end force extends outside the side wall surface of the hollow columnar body 1 good. Furthermore, in this example, the pressing protrusion 22 has a substantially disk-like shape, but a cutout portion is appropriately provided as long as the pressing function as described above is substantially exhibited. Alternatively, it may be a polygonal plate shape of a triangle or more connected in a disc shape, an elliptical plate shape, or a mountain shape with a hole in the center. In the embodiment of the hollow columnar body shown in FIG. 9, the protrusion 13 for preventing slipping is on the left and right outer sides of the side wall surface of the hollow columnar body 1, and one of the protrusions for preventing slipping (left side in FIG. 9) is hollow columnar. The hollow columnar body part 3 of the body 1 is below the upper end of the hollow cylindrical body part 3 but the other side (on the right side in FIG. 9) is provided with a protrusion for preventing it from coming out on the side wall surface in the longitudinal direction. The hollow columnar body 1 is provided on the side wall surface on the lower side of the hollow cylindrical body body portion 3. This drop-out prevention protrusion 13 is a drop-out prevention protrusion having a tapered rod-shaped cross-section with a substantially square rod shape, and the tip 13a is not thin like the drop-out prevention protrusion 12 in FIG. It opens diagonally upward with respect to the length direction of the cylindrical body part 3 It is provided at such an angle. It is preferable that the protrusions for slipping out have such a thin rod shape because the ratio of damaging the roots of plants is small.
[0060] この実施形態例の様に、押さえ用突起と抜け防止用突起を設けた中空柱状体は、 例えば、法面などに芝などを植え付ける場合には、法面に芝生マットなどを固定し、 風や雨などで当該法面に植え付けた芝生マットが剥がれてしまうことを防止する機能 が極めて優れている。押さえ用突起と抜け防止用突起を設けた中空柱状体を、芝生 マットおもて面力 差し込んで法面の土に芝生マットを固定すると、風などの力でマツ トが地面力 浮き上がろうとするのを押さえ用突起で押える機能が十分発揮され、且 つ、地面に打ち込まれた当該植物育成又は保護用柱状体が風などの力で芝生マツ トと共に抜けるのを抜け防止用突起で防止できるので、芝生マットや植生シート、植 生マットなどを固定する機能が一層強化され、植物保護用ネットなどを固定する場合 にも、極めて有効に使用できる。  [0060] As in this embodiment, the hollow columnar body provided with the pressing protrusion and the removal preventing protrusion has a lawn mat or the like fixed to the slope when planting grass or the like on the slope, for example. The function of preventing the grass mat planted on the slope from being peeled off by wind or rain is extremely excellent. Inserting a hollow columnar body with a holding protrusion and a slip-off prevention protrusion into the surface of the lawn mat and fixing the lawn mat to the sloped soil, the mat will lift the ground force with the force of the wind. The function of pressing the protrusion with the pressing protrusion is sufficiently exerted, and the plant-growing or protective columnar body driven into the ground can be prevented from coming off with the lawn mat by the force of wind etc. Therefore, the function of fixing lawn mats, vegetation sheets, vegetation mats, etc. is further strengthened, and can be used extremely effectively when fixing plant protection nets and the like.
[0061] また、必ずしも法面に限られず、比較的平坦な地形を有して!/、ても、特に風などの 強い地域に上述したような芝生マット、植生シート、植生マットなどを固定する場合に も本発明の押さえ用突起が少なくとも設けられた植物育成又は保護用柱状体は有効 に用いることができる。  [0061] In addition, it is not necessarily limited to a slope, and has a relatively flat terrain! / Even if a lawn mat, a vegetation sheet, a vegetation mat, etc. as described above are fixed to a particularly strong windy area. Even in this case, the plant growth or protection columnar body provided with at least the pressing protrusion of the present invention can be used effectively.
[0062] 本発明において押さえ用突起は、中空柱状体 1の側壁面外側の上端近傍に設けら れていればよぐ植物育成又は保護用柱状体の大きさにもよるが、中空柱状体 1の側 壁面外側の上端並びに上端から lcm下までの範囲で設けられていることが好ましい  [0062] In the present invention, the pressing protrusion is provided in the vicinity of the upper end on the outer side of the side wall surface of the hollow columnar body 1, although depending on the size of the plant growing or protecting columnar body, the hollow columnar body 1 It is preferable that it is provided in the range from the upper end of the outside of the wall surface to the lcm below the upper end.
[0063] 尚、押さえ用突起と抜け防止用突起を有する本発明の植物育成又は保護用柱状 体 30を林檎などの果榭 31に適用し、その根元の周りに動物忌避材を付着させた保 護用ネット 32を設け、ネットのストランドを引っ掛けて押えている状態の一実施形態例 を示す概念図を図 10に示した。野鼠などが林檎などの果樹の根元力もはい上がり、 新芽ゃ果榭をカゝじってしまうのを防止するため、動物忌避材を付着させた保護用ネッ ト 32を設け、本発明の植物育成又は保護用柱状体 30として、その中空部に動物忌 避剤、または動物忌避剤とそれ以外の植物の育成な 、し保護用薬剤とを組み合わ せた成分が充填された例えば図 8に示したような押さえ用突起と抜け防止用突起を 有する本発明の植物育成又は保護用柱状体 30 (図 10参照)を用いて、前記保護用 ネット 32の周囲縁のストランドを押さえ用突起(図 8の 21など参照)にて押さえ込む様 に植物育成又は保護用柱状体 30を地面に押し込んだものである。 [0063] It should be noted that the plant-growing or protective column 30 of the present invention having a pressing protrusion and a slip-preventing protrusion is applied to an orchard 31 such as an apple, and an animal repellent material is adhered around its root. FIG. 10 is a conceptual diagram showing an example of a state in which a protective net 32 is provided and a net strand is hooked and pressed. In order to prevent wild cabbage and other fruit trees from growing in the roots of apples and to catch new buds, a protective net 32 with animal repellent material is provided to grow the plant of the present invention. Alternatively, as the protective column 30, the hollow part is filled with an animal repellent, or a combination of an animal repellent and other plant repellent and a protective agent, for example, as shown in FIG. Such as a holding protrusion and a prevention protrusion The plant growth or protection columnar body 30 (see FIG. 10) of the present invention is used to grow the plant so that the strand at the peripheral edge of the protection net 32 is pressed by a pressing projection (see 21 in FIG. 8). Alternatively, the protective column 30 is pushed into the ground.
[0064] この様にすることにより、植物育成又は保護用柱状体 30中の動物忌避剤、並びに 保護用ネット 32に付着している動物忌避剤により、野鼠などの有害動物から果榭を 保護することができ、風などが吹いても、保護用ネット 32は、植物育成又は保護用柱 状体 30の押さえ用突起(図 8の 21など参照)にて押さえ込まれているので、保護用ネ ット 32が吹き飛んでしまうことがなぐ有効に動物忌避作用を発揮できる。柱状体 30 の中空部に動物忌避剤のみでなぐ例えば肥料などが混合されていれば、動物忌避 作用と、当該果樹の生育作用が発揮されることになる。  [0064] By doing so, fruit repellants are protected from harmful animals such as wild boars with animal repellents in the plant growth or protection column 30 and animal repellents attached to the protection net 32. Even if wind blows, the protective net 32 is pressed by the pressing protrusions (see 21 in FIG. 8) of the plant growing or protective column 30. It is possible to exert the animal repellent effect effectively without the G 32 being blown away. If the hollow part of the columnar body 30 is mixed with, for example, fertilizers that are only mixed with animal repellents, the animal repellent action and the fruit tree growing action are exhibited.

By setting the thickness within this range, there is no problem that the thickness is too thin, and when plant growth or a protective columnar body is driven into the soil, the strength is too weak to easily collapse. The upper limit may be appropriately determined in consideration of the target time required for the complete growth of the plant growing or protecting agent completely biodegraded and filled in the hollow part. In particular, when a slower acting columnar body is used, the thickness of the hollow columnar body is preferably greater than 2 mm. Further, in the case of a more immediate type columnar body, the thickness of the hollow columnar body is preferably 1 to 2 mm.
すなわち厚みが薄いほど早く分解され、厚みが厚いほど分解されるのに時間がかか るので、目標とする分解時間に応じて適宜厚みを選定することが好ましい。  That is, the thinner the thickness, the faster it is decomposed, and the thicker the time it takes for the material to be decomposed. Therefore, it is preferable to select an appropriate thickness according to the target decomposition time.

By providing the small holes, from when the plant growing or protecting columnar body of the present invention is applied to the soil, until the hollow columnar body of the plant growing or protecting columnar body is almost biodegraded. When a plant growth or protection agent gradually acts effectively through the small holes, the hollow columnar body is almost completely biodegraded and the shape of the hollow columnar body collapses. The drug effect will act. In the plant growth or protection columnar body of the present invention, the degree to which the plant growth or protection agent filled in the hollow portion acts can be gradually adjusted by appropriately adjusting the size and number of the small holes ( (Slow effect) or faster (fast effect). Also, considering the total area of a plurality of small holes provided in the hollow columnar body, it can be made smaller to make it a slow-acting type, or it can be made to be a fast-acting type by making it larger. In this way, by adjusting the number and size of the plurality of small holes to be provided, the amount of action and the time of action of the drug appropriate for the type of drug used and the type of plant to be applied are met. Things can be provided easily and easily It is possible to create a slow-acting type and a fast-acting type of various grades, and by using different types and grades of biodegradable plastics, create a fast-acting type separately. Compared to the case, the manufacturing is easy, and the type can be arbitrarily selected according to the purpose by adjusting the number and size of the small holes.
[0087] また、小孔の大きさは、中空柱状体の太さ、長さなどの大きさによっても変わるが、 通常前記小孔の径は 1〜: LOmm程度が好ましぐより好ましくは 3〜 7mm程度、更に 好ましくは 4〜6mm程度である。あまり小孔の径力 、さ過ぎると小孔を開けた効果が 発揮されないし、あまり小孔の径が大き過ぎると、臭いの強いものは臭いが強く感じら れ不快感を与えやすくなつたり、カビが発生しやすくなる傾向がある。小孔の径は小 孔が円以外の形状の際は、同面積の円に換算した際の円の直径とする。  [0087] The size of the small holes also varies depending on the thickness, length, etc. of the hollow columnar body. Usually, the diameter of the small holes is preferably about 1 to: LOmm, more preferably 3 About 7 mm, more preferably about 4-6 mm. If the diameter of the small hole is too large, the effect of opening the small hole will not be exerted.If the diameter of the small hole is too large, a strong smell will be felt strong and uncomfortable.
