Description

植物生育用シート、及び、植物生育用袋Plant growth sheet and plant growth bag
 本発明は、栽培土又は培地に根付いた植物の周囲を覆って内部で前記植物を生育させる樹脂製の植物生育用シート、及び、これから形成した植物生育用袋に関する。 The present invention relates to a resin-made plant growth sheet that covers the periphery of a plant rooted in cultivated soil or a medium and grows the plant therein, and a plant growth bag formed therefrom.
 観賞のために植物を長期間放置しながら生育させることが試みられている。そのためには、植物を根付かせた栽培土や培地に長期間水を保持させることが必要となる。しかし、単に栽培土や培地に水を含ませただけでは、栽培土や培地、そして特に植物の葉面から水分が周囲環境へと蒸発してしまう。そのため、水を栽培土や培地に追加して与えることなくそのまま放置すると、栽培土や培地から水が速やかに失われて、植物に水を与えることができなくなり、その結果、植物は枯れてしまう(図5,表4参照)。 An attempt has been made to grow a plant while leaving it for a long time for viewing. For that purpose, it is necessary to retain water for a long time in the cultivation soil or culture medium in which the plant is rooted. However, if water is simply contained in the cultivated soil or culture medium, water will evaporate from the cultivated soil or culture medium, and particularly from the leaves of the plant, to the surrounding environment. Therefore, if it is left as it is without adding water to the cultivated soil or culture medium, the water is quickly lost from the cultivated soil or culture medium and water cannot be given to the plant, and as a result, the plant will die. (See FIG. 5 and Table 4).
 これに対し、栽培土又は培地に根付かせた植物をシートで覆ったり、袋に入れて外部への水分の蒸発を防ぐことが考えられる。この場合、植物を袋に入れて保管することで、植物の葉面、栽培土や培地からの水の蒸発を抑制することはできる。しかし、シートや袋内に水蒸気が過度にこもることとなり、その結果、シートや袋内面に結露が生じて鑑賞性を損ない、さらには、その結露で雑菌が繁殖し、それが植物に感染した結果、植物を腐る等の不具合が起きる(図6,表5参照)。 On the other hand, it is conceivable to cover the plant rooted in the cultivation soil or culture medium with a sheet or put it in a bag to prevent evaporation of moisture to the outside. In this case, by storing the plant in a bag, the evaporation of water from the leaf surface of the plant, the cultivated soil, or the culture medium can be suppressed. However, water vapor is excessively trapped in the sheet or bag, resulting in condensation on the inner surface of the sheet or bag and deteriorating appreciation. This causes problems such as rotting plants (see FIG. 6 and Table 5).
 つまり、植物を単に放置すると、まめに水を補給しなければ速やかに枯れてしまい、一方、植物を袋等にいれて保管すると、水を補給する必要はなくなるが、水分が内部にこもりすぎて見た目が悪くなると共に、植物を腐らせてダメにしてしまう。このように、植物を長期間放置しながら生育させることは困難であった。 In other words, if a plant is simply left unattended if it is not frequently replenished with water, it will die quickly.On the other hand, if the plant is stored in a bag or the like, it will not be necessary to replenish water, but water will be trapped inside. As it looks bad, it rots the plant and makes it bad. As described above, it was difficult to grow the plant while leaving it for a long time.
 そこで、長期間放置しても植物を枯らさず、且つ、腐らせることなく、植物を内部に収容して生育可能な植物生育用シート、及び、植物生育用袋が望まれる。 Therefore, a plant growth sheet and a plant growth bag that can grow by accommodating the plant inside without causing the plant to die or rot even if left for a long period of time are desired.
 本発明に係る植物生育用シートは、
 栽培土又は培地に根付いた植物の周囲を覆って内部で前記植物を生育させる樹脂製の植物生育用シートであって、
 40℃、90%RHにおける透湿度が55~120g/m・24hである。
The plant growth sheet according to the present invention comprises:
A resinous plant growth sheet that covers the periphery of the plant rooted in the cultivated soil or medium and grows the plant inside,
The moisture permeability at 40 ° C. and 90% RH is 55 to 120 g / m 2 · 24 h.
 この構成によれば、40℃、90%RHにおける透湿度が55~120g/m・24hの範囲とすることにより、この植物生育用シートで植物の周囲を覆って植物をその内部に収容することで、例えば図2に示すように、緩やかに水分を外部に放出させることができる。このため、植物の葉面、栽培土や培地からの水の蒸発を抑制して水を栽培土又は培地に適度に保たせつつ、内部に結露が生じるほどの水蒸気がこもらない程度に適度に水蒸気を外部に放出させることが可能となる。その結果、本構成によれば、植物を腐らせたり枯らしたりすることなく、栽培土又は培地に予め含ませた水のみで長期間の保管が可能となる。 According to this configuration, by setting the moisture permeability at 40 ° C. and 90% RH to be in the range of 55 to 120 g / m 2 · 24 h, the plant is covered with the plant growth sheet and the plant is accommodated therein. Thus, for example, as shown in FIG. 2, moisture can be gradually released to the outside. For this reason, water vapor is moderately controlled so that the water vapor from the inside of the plant is not confined while the water is appropriately kept in the cultivation soil or medium by suppressing the evaporation of water from the foliage of the plant, the cultivation soil or the medium. Can be released to the outside. As a result, according to the present configuration, long-term storage can be performed only with water preliminarily contained in the cultivated soil or culture medium without causing the plant to decay or wither.
 1つの態様として、所望の透湿度を得るために、多数の微細な貫通孔が設けられていると好適である。 As one aspect, it is preferable that a large number of fine through holes are provided in order to obtain a desired moisture permeability.
 この構成によれば、55g/m・24h以下の透湿度の樹脂製シートであっても、貫通孔を設けるという後加工により所望の透湿度を得ることができ、素材に限定されることなく植物生育用シートを製造することができる。 According to this structure, even if it is a resin-made sheet | seat of the moisture permeability of 55 g / m < 2 > * 24h or less, desired moisture permeability can be obtained by the post-processing of providing a through-hole, and it is not limited to a raw material A plant growth sheet can be produced.
 1つの態様として、PETからなるシートとポリエチレンからなるシートとが積層されたものであると好適である。 As one aspect, it is preferable that a sheet made of PET and a sheet made of polyethylene are laminated.
 この構成によれば、低コストで、且つ、強度(いわゆるコシ)・透明性の高いPETからなる樹脂製シートと、シートを袋状に成形するために必要なヒートシールを行い易いポリエチレンからなる樹脂製シートとを積層したものとすることで、ヒートシールによって容易に袋状に成形することができるとともに、その強度・透明性から包装時の形状や袋状としたときの形状を好適に保ちつつ内部の植物を良好に観賞できる。 According to this configuration, a low-cost resin sheet made of PET with high strength (so-called stiffness) and transparency, and a resin made of polyethylene that is easy to perform heat sealing necessary to form the sheet into a bag shape. By stacking the sheet with the product, it can be easily formed into a bag shape by heat sealing, while maintaining its shape at the time of packaging and bag shape from its strength and transparency. You can appreciate the plants inside.
 本発明に係る植物生育用袋は、
 上記の1又は複数の植物生育用シートが袋状に形成されている。
The plant growth bag according to the present invention comprises:
The one or more plant growth sheets are formed in a bag shape.
 この構成によれば、上記した本発明に係る植物生育用シートを用いて形成することにより、その内部に植物を収容することで、植物を腐らせたり枯らしたりすることなく、栽培土又は培地に予め含ませた水のみで長期間の保管が可能となる。 According to this configuration, by forming the plant growth sheet according to the present invention as described above, the plant is accommodated therein, so that the plant can be cultivated or cultured without causing the plant to decay or die. Long-term storage is possible only with water contained in advance.
 1つの態様として、底部用シートからなる底部を有し、前記底部により自立可能であり、前記底部用シートの透湿度は前記樹脂製シートの透湿度より低い値であると好適である。 As one aspect, it has a bottom part made of a sheet for the bottom part and can be self-supporting by the bottom part, and the moisture permeability of the sheet for the bottom part is preferably lower than the moisture permeability of the resin sheet.
 この構成によれば、他の器具等を用いることなく底部によって自立させることができる。また、栽培土又は培地が接触することになる底部は透湿度を低くしてあるので、栽培土又は培地に含まれる水が底部から漏れ出すことを効果的に抑制できる。 According to this configuration, it can be made independent by the bottom without using other instruments. Moreover, since the bottom part which cultivation soil or a culture medium contacts has made moisture permeability low, it can suppress effectively that the water contained in cultivation soil or a culture medium leaks out from a bottom part.

 本発明に係る植物生育用シート、及び、植物生育用袋の実施形態について、図面を参照して説明する。図1は、本発明の一実施形態である、植物生育用シートを用いた植物生育用袋1を示す。概要について説明すると、植物生育用シートは、栽培土又は培地に根付いた植物7の周囲を覆って内部で植物7を生育させる樹脂製のシートであり、40℃、90%RHにおける透湿度(以下、単に透湿度と称する)が55~120g/m・24hであることを特徴としている。そして、本実施形態の植物生育用袋1は、この植物生育用シートが袋状に形成されたものである。より詳しくは、植物生育用袋1には、それぞれ表面2,裏面3、及び、底部4となる3枚の樹脂製シートから形成されており、表面2及び裏面3となる樹脂製シートに植物生育用シートが用いられている。一方、植物生育用袋1は底部4により自立可能となっており、このため、底部4となる底部用シートにはこの透湿度加工は施されておらず、この底部用シートの透湿度は表面2及び裏面3となる樹脂製シートの透湿度より低い値となっている。このように、本実施形態の植物生育用袋1では、表面2及び裏面3が植物生育用シートを用いて形成されており、植物7の周囲を植物生育用シートで覆って内部で植物7を生育させるものとなっている。以下、この本実施形態の植物生育用袋1について具体的に説明する。
〔透湿度〕
 まず、本実施形態の植物生育用袋1では、透湿度が55~120g/m・24hである植物生育用シートを表面2及び裏面3に用いていることが特徴となっている。透湿度をこの値の範囲内としているのは、透湿度が55g/m・24hを下回ると、袋内部に水蒸気が過剰にこもることになり、植物が腐る虞があり、透湿度が120g/m・24hを超えると、袋内の水蒸気が外部に放出されやすく、植物7を根付かせた栽培土又は培地から水が失われるスピードが早くなってしまうため、長期間放置して管理することができなくなるからである。
DESCRIPTION OF EMBODIMENTS Embodiments of a plant growth sheet and a plant growth bag according to the present invention will be described with reference to the drawings. FIG. 1 shows a plant growth bag 1 using a plant growth sheet according to an embodiment of the present invention. To explain the outline, the plant growth sheet is a resin-made sheet that covers the periphery of the plant 7 rooted in the cultivated soil or culture medium and grows the plant 7 inside. , Simply referred to as moisture permeability) is 55 to 120 g / m 2 · 24 h. And the bag 1 for plant growth of this embodiment is what this sheet | seat for plant growth was formed in the bag shape. More specifically, each of the plant growth bags 1 is formed of three resin sheets serving as the front surface 2, the back surface 3, and the bottom portion 4, and the plant growth is formed on the resin sheets serving as the front surface 2 and the back surface 3. Sheets are used. On the other hand, the plant growth bag 1 can be self-supported by the bottom portion 4, and therefore, the moisture permeability of the bottom portion sheet is not applied to the bottom portion sheet. 2 and the moisture permeability of the resin sheet used as the back surface 3 are lower. Thus, in the plant growth bag 1 of the present embodiment, the front surface 2 and the back surface 3 are formed using the plant growth sheet, and the plant 7 is covered with the plant growth sheet so that the plant 7 is covered inside. It is supposed to grow. Hereinafter, the plant growth bag 1 of this embodiment will be described in detail.
[Moisture permeability]
First, the plant growth bag 1 of the present embodiment is characterized in that a plant growth sheet having a moisture permeability of 55 to 120 g / m 2 · 24 h is used for the front surface 2 and the back surface 3. The moisture permeability is within the range of this value. If the moisture permeability is less than 55 g / m 2 · 24 h, water vapor may be excessively accumulated in the bag, and the plant may be rotted. If it exceeds m 2 · 24h, the water vapor in the bag is likely to be released to the outside, and the speed at which water is lost from the cultivation soil or culture medium in which the plant 7 is rooted becomes faster. It is because it becomes impossible.
 なお、透湿度は、保管期間に合わせて適宜変更可能である。例えば、透湿度の値が低いほど、袋内の水蒸気が外部に放出されにくくなって栽培土又は培地から水が失われるスピードは遅くなるが、反対に袋内部に水蒸気がこもりやすくなって植物が腐りやすくなってしまう。一方、透湿度の値が高いほど、袋内の水蒸気が外部に放出されやすくなって袋内部に水蒸気がこもりにくいが栽培土又は培地から水が失われるスピードは速くなる。このため、植物をより長期間放置しながら生育させることを目的とするときは、透湿度55~120g/m・24hの中央付近の値を採ることが好ましく、したがって、透湿度が65~105g/m・24hであると好ましい。また、それほど長期間の放置を予定していない場合には、透湿度55~120g/m・24hの上限や下限付近としてもよい。なお、透湿度はJIS Z-0208により測定することができる。 The moisture permeability can be changed as appropriate according to the storage period. For example, the lower the value of moisture permeability, the less the water vapor in the bag is released to the outside and the slower the water is lost from the cultivated soil or culture medium. It becomes easy to rot. On the other hand, the higher the value of moisture permeability, the easier it is for the water vapor in the bag to be released to the outside, and the water vapor from the cultivation soil or culture medium becomes faster, although the water vapor is less likely to stay inside the bag. For this reason, when the plant is intended to grow while standing for a longer period of time, it is preferable to take a value near the center of the moisture permeability of 55 to 120 g / m 2 · 24 h, and therefore the moisture permeability is 65 to 105 g. / M 2 · 24h is preferable. In addition, in the case where it is not planned to leave for a long time, the upper limit or the lower limit of the moisture permeability of 55 to 120 g / m 2 · 24 h may be set. The moisture permeability can be measured according to JIS Z-0208.
〔透湿度加工〕
 本実施形態では、表面2及び裏面3となる植物生育用シートに、所望の透湿度を得るために、透湿度加工として、多数の微細な貫通孔が設けられている。この貫通孔の大きさや数密度を調整することにより、所望の透湿度を得ることができる。その方法としては、例えば、特公平6-61859号公報に開示された装置のように、ローラーの表面に多数の硬い粒子を付着し、そのローラーを樹脂製シートに押し当てた状態でローラーを転がすことによって、樹脂製シートに多数の微細な貫通孔を設けることができる。これにより、55g/m・24h以下の透湿度の樹脂製シートであっても、貫通孔を設けるという後加工により所望の透湿度を得ることができ、素材に限定されることなく好適な植物生育用シートを製造することができる。
[Moisture permeability processing]
In the present embodiment, a large number of fine through holes are provided in the plant growth sheet serving as the front surface 2 and the back surface 3 as moisture permeability processing in order to obtain a desired moisture permeability. The desired moisture permeability can be obtained by adjusting the size and number density of the through holes. As the method, for example, as in the apparatus disclosed in Japanese Patent Publication No. 6-61859, a large number of hard particles are attached to the surface of the roller, and the roller is rolled with the roller pressed against the resin sheet. Thus, a large number of fine through holes can be provided in the resin sheet. Thereby, even if it is a resin-made sheet | seat of moisture permeability of 55 g / m < 2 > * 24h or less, desired moisture permeability can be obtained by the post-processing of providing a through-hole, and it is suitable for a plant without being limited to a raw material A growth sheet can be produced.
 なお、上記した範囲の透湿度を得る方法は多数の微細な貫通孔を設ける方法に限られず、適宜選択して用いることができる。また、このような透湿度加工を行うことなく、製造時から上記した範囲の透湿度となる樹脂製シートを植物生育用シートとして用いてもよい。 In addition, the method of obtaining the moisture permeability in the above-described range is not limited to the method of providing a large number of fine through holes, and can be appropriately selected and used. Moreover, you may use the resin-made sheet | seat which becomes the moisture permeability of the above-mentioned range from manufacture at the time of manufacturing, without performing such a moisture permeability process.
〔植物生育用袋の構造〕
 本実施形態の植物生育用袋1は、上記のようにして所望の透湿度となった2枚の植物生育用シートを表面2及び裏面3とし、その2枚の植物生育用シートと上記の透湿度加工を行っていない底部用樹脂製シートとが互いに貼り合わされて、いわゆるスタンディングパウチ構造で形成されている。スタンディングパウチ構造とするには公知の方法を用いればよく、詳細な説明は省略するが、具体的には、表面2及び裏面3となる植物生育用シートを重ねあわせると共に、両樹脂製シートの下側に折り込みを入れた底部用樹脂製シートを挟み込み、その側辺と底辺部分をヒートシール5により貼りあわせてある。このように構成することで、底部4により自立可能なスタンディングパウチ構造となっている。そして、開放された状態の上部から対象の植物を袋内部に入れ、その後、上部の適当箇所をヒートシール等により貼りあわせることで袋内部がヒートシール5によって密閉された状態となり、完成する。
[Structure of plant growth bag]
In the plant growth bag 1 of the present embodiment, the two plant growth sheets having the desired moisture permeability as described above are used as the front surface 2 and the back surface 3, and the two plant growth sheets and the above-described transparent material are used. A bottom resin sheet not subjected to humidity processing is bonded to each other to form a so-called standing pouch structure. A well-known method may be used to obtain a standing pouch structure, and detailed description is omitted. Specifically, the plant growth sheets to be the front surface 2 and the back surface 3 are overlapped, and under both resin sheets. A resin sheet for the bottom portion that is folded on the side is sandwiched, and the side and the bottom portion are bonded together by the heat seal 5. With this configuration, a standing pouch structure that can stand on its own by the bottom 4 is formed. Then, the target plant is put into the bag from above in the opened state, and then the upper portion is pasted together by heat sealing or the like, whereby the inside of the bag is sealed by the heat seal 5 and completed.
 このように袋内部が密閉された状態にあるため、水蒸気が発生したときは、表面2及び裏面3の透湿度に応じて水蒸気が外部に放出されることとなる。また、底部4により自立可能となっているため、自立した状態で陳列させたり、自宅等で観賞することが可能となっている。上部のヒートシール5の上側にはパンチ穴6も開けてあり、パンチ穴6により吊り下げた状態で陳列させたり、また観賞することもできる。その他、底部4となる底部用シートには透湿度加工は施さず、底部用シートの透湿度は植物生育用シートの透湿度より低い値としてあるので、栽培土又は培地に含まれる水が底部4から漏れ出すことを効果的に抑制できる。つまり、本実施形態の植物生育用袋1では、袋内部には栽培土又は培地に根付いた植物を収容し、このとき、植物を根付かせ栽培土又は培地は水を含ませた状態とするのであるが、栽培土又は培地が接触する底部4について透湿度を低くすることで、栽培土又は培地に含まれる水が底部から漏れ出すことを効果的に抑制してある。 Since the inside of the bag is sealed in this manner, when water vapor is generated, the water vapor is released to the outside according to the moisture permeability of the front surface 2 and the back surface 3. Moreover, since it can become independent by the bottom part 4, it can be displayed in an independent state or can be viewed at home or the like. A punch hole 6 is also formed on the upper side of the upper heat seal 5 so that it can be displayed in a state of being suspended by the punch hole 6 or can be viewed. In addition, the bottom sheet that becomes the bottom 4 is not subjected to moisture permeability processing, and the moisture permeability of the bottom sheet is lower than the moisture permeability of the plant growth sheet. It is possible to effectively suppress leakage from the. That is, in the bag 1 for plant growth of this embodiment, the plant rooted in cultivation soil or a culture medium is accommodated inside the bag, and at this time, the plant is rooted and the cultivation soil or culture medium is in a state of containing water. However, it is possible to effectively suppress leakage of water contained in the cultivated soil or the medium from the bottom by lowering the moisture permeability of the bottom 4 that the cultivated soil or the medium contacts.
 なお、各樹脂製シートは必ずしもヒートシール5によって貼りあわせる必要はなく、他の適当な手段を用いて貼りあわせてもよい。例えば、袋内部をヒートシール5によって密閉された状態とするのではなく、図1においてヒートシールとしている一部をチャックなどの開閉機構に置き換えるなど、植物生育用袋1を開閉可能な開閉機構を設け、必要時にその開閉機構を開けて、内部の植物を取り出して、植物の栽培土又は培地に水を追加補給可能にしてもよい。その他、植物の栽培土又は培地に水を追加供給するためのスポイトの先端を袋内部に挿入可能な差し込み孔を植物生育用袋1の任意箇所に設けてもよい。この場合、差し込み孔を閉鎖可能な蓋部も併せて設けるとよい。 Note that the resin sheets are not necessarily bonded together by the heat seal 5, and may be bonded using other appropriate means. For example, an opening / closing mechanism capable of opening and closing the plant growth bag 1 is provided, such as replacing a part of the heat seal in FIG. 1 with an opening / closing mechanism such as a chuck, instead of sealing the inside of the bag with the heat seal 5. If necessary, the opening and closing mechanism may be opened to take out the plant inside, so that additional water can be supplied to the plant cultivation soil or medium. In addition, you may provide the insertion hole which can insert the front-end | tip of a dropper for adding water to the cultivation soil or culture medium of a plant in the bag inside the bag 1 for plant growth. In this case, a lid that can close the insertion hole may also be provided.
 そのほか、本実施形態の植物生育用袋1は必ずしもスタンディングパウチ構造である必要はなく、透湿度が55~120g/m・24hである植物生育用シートを用いて袋状に形成されるものであれば、どのような形状であってもよく、例えば、2枚の植物生育用シートをその端縁で貼りあわせたり、1枚の植物生育用シートを折り返して重ねあわせた端縁を貼りあわせて形成してもよい。また、底部4については透湿度加工が施されていないものとする必要もなく、底部4についても透湿度が55~120g/m・24hである植物生育用シートから形成されるようにしてもよい。 In addition, the plant growth bag 1 of this embodiment does not necessarily have a standing pouch structure, and is formed into a bag shape using a plant growth sheet having a moisture permeability of 55 to 120 g / m 2 · 24 h. As long as there is any shape, for example, two plant growth sheets are pasted together at their edges, or one plant growth sheet is folded back and pasted together. It may be formed. Further, it is not necessary that the bottom portion 4 is not subjected to moisture permeability processing, and the bottom portion 4 is also formed from a plant growth sheet having a moisture permeability of 55 to 120 g / m 2 · 24 h. Good.
 次に、本実施形態の植物生育用シートに用いる素材について説明する。本実施形態では、植物生育用シートとしてPETからなるシートとポリエチレンからなるシートとが積層された積層シートが用いられている。また、底部用樹脂製シートも同様にPETからなるシートとポリエチレンからなるシートとが積層された積層シートが用いられている。そして、表面2、裏面3に用いる積層シートについては上記の透湿度加工を施して植物生育用シートとし、底部4に用いる積層シートについては上記の透湿度加工を施していない。 Next, the material used for the plant growth sheet of this embodiment will be described. In the present embodiment, a laminated sheet in which a sheet made of PET and a sheet made of polyethylene are laminated is used as the plant growth sheet. Similarly, as the bottom resin sheet, a laminated sheet in which a sheet made of PET and a sheet made of polyethylene are laminated is used. And about the laminated sheet used for the surface 2 and the back surface 3, the said moisture-permeable process is given to make a plant growth sheet, and the laminated sheet used for the bottom part 4 is not given the above-mentioned moisture-permeable process.
 このように、低コストで、且つ、強度(いわゆるコシ)・透明性の高いPETからなるシートと、シートを袋状に成形するために必要なヒートシールを行い易いポリエチレンからなるシートとを積層した樹脂製シートを用いることで、ヒートシールによって容易に袋状に成形することができるとともに、その強度・透明性から包装時の形状や袋状としたときの形状を好適に保ちつつ内部の植物を良好に観賞できる。 In this way, a sheet made of PET with low cost and high strength (so-called stiffness) / transparency and a sheet made of polyethylene that is easy to heat seal necessary to form the sheet into a bag shape were laminated. By using a resin sheet, it can be easily formed into a bag shape by heat sealing, and the inner plant can be maintained while maintaining the shape at the time of packaging and the shape of the bag shape from its strength and transparency. Good appreciation.
 なお、植物生育用シートや底部用樹脂製シートの素材はこれに限定されることはなく、その他、ポリエステル、ナイロン、セロハンなどを単独で、又はこれらを組み合わせて積層させたものを用いてもよい。 The material for the plant growth sheet and the bottom resin sheet is not limited to this, and other materials such as polyester, nylon, cellophane, etc. may be used alone or in combination. .
 また、本実施形態の植物生育用袋1に用いる植物は、切り花や収穫後の青果物などを対象とするのではなく、栽培土又は培地に根付いた状態にあり現に生きて呼吸や蒸散を行う植物を対象としている。そして、植物生育用袋1内で栽培土又は培地に根付かせて生育可能であれば特に限定されず、例えば、プテオラータ、テーブル椰子、ポトス、ポトスライム、オキシブラジル、サンデリアーナ、ベゴニア等の一般観葉植物、花苗、野菜苗などが挙げられる。培地についても特に限定されず、保水スポンジなど適宜自由に選択可能であり、また、小型の植木鉢等の容器を用いてその容器内で栽培土に植物を根付かせ、容器ごと本実施形態の植物生育用袋1に収容するようにしてもよい。 Moreover, the plant used for the bag 1 for plant growth of this embodiment does not target cut flowers or harvested fruits and vegetables, but is a plant that is rooted in the cultivated soil or culture medium and actually respires and transpirations. Is targeted. And it will not specifically limit if it can grow by rooting in the cultivation soil or culture medium in the bag 1 for plant growth, for example, general ornamental plants, such as pteolata, table eggplant, potos, potoslime, oxy-Brazil, sundeliana, begonia, Examples include flower seedlings and vegetable seedlings. The medium is not particularly limited, and can be freely selected as appropriate, such as a water-retaining sponge. In addition, a plant such as a small flower pot is used to root a plant in the cultivated soil, and the whole plant grows in this embodiment. You may make it accommodate in the bag 1.
〔実施例〕
 次に、本実施形態の植物生育用袋1を実際に用いた実施例について説明する。図2は、培地の一例としてのパフカル(登録商標、サントリーホールディングス株式会社)に種々の植物を根付かせ、パフカルに十分量の水を含ませた状態でそれぞれ本実施形態の植物生育用袋1に収容して、そのまま水を補給することなく放置したときの全体の重量(袋を除く)の時間変化を示す。植物生育用袋1に用いた各植物生育用シートの透湿度は、平均値がおよそ79g/m・24h(最小はおよそ68g/m・24hで最大がおよそ100g/m・24h)となっている。なお、表面2及び裏面3における袋部分(いわば、ヒートシール5の内側部分)の寸法はそれぞれ145mm×300mmであり、植物生育用袋1あたりの水蒸気透過量はおよそ6.8g/24h(79g/m・24h×0.145m×0.300m×2)となる。
〔Example〕
Next, an example in which the plant growth bag 1 of this embodiment is actually used will be described. FIG. 2 shows a plant growth bag 1 of the present embodiment in which various plants are rooted in puffal (registered trademark, Suntory Holdings, Ltd.) as an example of a medium, and a sufficient amount of water is contained in the puffal. It shows the time change of the total weight (excluding the bag) when stored and left without being refilled with water. Moisture permeability of the plant growth sheet used in the plant growth bag 1 has an average value of approximately 79g / m 2 · 24h (minimum approximately 68 g / m up to 2 · 24h is approximately 100g / m 2 · 24h) It has become. In addition, the dimension of the bag part (in other words, the inner part of the heat seal 5) on the front surface 2 and the back surface 3 is 145 mm × 300 mm, respectively, and the water vapor permeation amount per plant growth bag 1 is approximately 6.8 g / 24 h (79 g / m 2 · 24h × 0.145 m × 0.300 m × 2).
 まず、図2に示すように、本実施形態の植物生育用袋1を用いることで、緩やかに全体の重量が減少していることがわかる。これは、植物生育用袋1から緩やかなペースで水蒸気が外部に逃げていっていることを示す。そして、次の表1に、各植物についての状態の変化を示す。○は植物や袋内に変化が特に変化が生じていないことを示し、×は植物又は袋内に何らかの異常が生じたことを示す。 First, as shown in FIG. 2, it can be seen that the overall weight is gradually reduced by using the plant growth bag 1 of this embodiment. This indicates that water vapor escapes from the plant growth bag 1 to the outside at a moderate pace. And in the following Table 1, the change of the state about each plant is shown. ○ indicates that there is no particular change in the plant or bag, and x indicates that some abnormality has occurred in the plant or bag.

 表1から明らかなように、ポトスを除けば、41日経過時点も植物や袋内になんらの異常を生じていない。また、ポトスについては41日経過時点に枯葉が生じているが、その前では植物や袋内になんらの異常を生じていない。このように、本実施形態の植物生育用袋1では、図2に示すように緩やかに水蒸気を外部に逃がすことができるため、袋内部の湿度を結露の生じさせることのない適度な湿度に保つことができ、また、適度な湿度に保つことにより、水を補給することなく放置したときでもパフカル(即ち、栽培土や培地)に水を長期間保つことができ、少なくとも30~40日間の長期保存が可能になっている。 As is clear from Table 1, with the exception of Potos, there was no abnormality in plants or bags even after 41 days. In addition, with regard to Potos, dead leaves have occurred at the time when 41 days have passed, but before that, no abnormality has occurred in the plant or bag. In this way, in the plant growth bag 1 of this embodiment, as shown in FIG. 2, water vapor can be gradually released to the outside, so that the humidity inside the bag is kept at an appropriate level without causing condensation. In addition, by maintaining an appropriate humidity, water can be maintained in puffal (ie, cultivated soil and culture medium) for a long period of time even when left without being replenished, and for a long period of at least 30 to 40 days. Saving is possible.
〔比較例1〕
 比較例1として、本実施形態の植物生育用袋1に対する裏面3に実施例とおなじ植物生育用シートを用い、表面2となる樹脂製シートについては透水度加工を施さなかったシートを用いた植物生育用袋による例について説明する。なお、表面2となる樹脂製シートの透湿度はおよそ7.1g/m・24hであった。図3は、実施例と同様に、パフカルに種々の植物を根付かせ、パフカルに十分量の水を含ませた状態で、本比較例1の植物生育用袋に収容してそのまま水を補給することなく放置したときの全体の重量(袋を除く)の時間変化を示す。
[Comparative Example 1]
As Comparative Example 1, a plant using the same sheet for plant growth as the example on the back surface 3 with respect to the plant growth bag 1 of the present embodiment, and a resin sheet that has not been subjected to water permeability processing for the resin sheet that becomes the surface 2 An example using a growth bag will be described. The water vapor permeability of the resin sheet serving as the surface 2 was approximately 7.1 g / m 2 · 24 h. FIG. 3 is similar to the Example, in which various plants are rooted in the puffal, and in a state where the puffal contains a sufficient amount of water, it is accommodated in the plant growth bag of this Comparative Example 1 and replenished with water. It shows the change over time of the total weight (excluding the bag) when left without.
 図3から明らかなように、図2(実施例)よりも、各植物について総重量の時間変化が小さく、即ち、袋内から水蒸気があまり逃げて行っていないことがわかる。次の表2に、各植物についての状態の変化を示す。 As is clear from FIG. 3, it can be seen that the time change of the total weight of each plant is smaller than that of FIG. 2 (Example), that is, the steam does not escape much from the bag. Table 2 below shows the change in state for each plant.
Figure JPOXMLDOC01-appb-T000002
Figure JPOXMLDOC01-appb-T000002
 表2から明らかなように、テーブル椰子を除けば、28日経過時点に葉の表面に水滴が生じ始めるか、さらには葉が黄色に変色してしまっているなど、何らかの異常が生じてしまっていることがわかる。 As is clear from Table 2, some abnormalities have occurred, with the exception of the table insulator, that water droplets have begun to appear on the surface of the leaves after 28 days, or that the leaves have turned yellow. I understand that.
〔比較例2〕
 比較例2として、実施例のものより透湿度の低い樹脂製シートを同形状に形成した植物生育用袋を用いた例を説明する。比較例2に用いた各樹脂製シートの透湿度は、平均値がおよそ43g/m・24h(最小はおよそ35g/m・24hで最大がおよそ53g/m・24h)であった。図4は、パフカルにプテオラータを根付かせ、パフカルに十分量の水を含ませた状態で、本比較例2の植物生育用袋に収容してそのまま水を補給することなく放置したときの全体の重量(袋を除く)の時間変化を示す。
[Comparative Example 2]
As Comparative Example 2, an example using a plant growth bag in which a resin sheet having a moisture permeability lower than that of the example is formed in the same shape will be described. The moisture permeability of each resin sheet used in Comparative Example 2 was about 43 g / m 2 · 24 h (minimum is about 35 g / m 2 · 24 h and maximum is about 53 g / m 2 · 24 h). FIG. 4 shows the entire state when the pateolata is rooted in the puffal and the puffal is contained in a sufficient amount of water and then stored in the plant growth bag of this Comparative Example 2 without being replenished with water. The time change of a weight (except a bag) is shown.
 図4から、図2(実施例)よりも総重量の時間変化が小さく、即ち、袋内から水蒸気があまり逃げて行っていないことがわかる。次の表3に、プテオラータについての状態の変化を示す。 FIG. 4 shows that the change in the total weight with time is smaller than that in FIG. 2 (Example), that is, the steam does not escape from the bag. Table 3 below shows the change in state for the pteolata.

 表3から明らかなように、17日経過時点で枯葉が一枚生じ、さらに、28日経過時点でもう一枚枯葉が生じた。このように、実施例のものより透湿度の低い樹脂製シートを用いることにより、植物に異常が生じてしまっていることがわかる。 As is apparent from Table 3, one dead leaf occurred after 17 days, and another dead leaf occurred after 28 days. Thus, it turns out that abnormality has arisen in the plant by using the resin-made sheet | seat whose moisture permeability is lower than the thing of an Example.
〔比較例3〕
 比較例3として、実施例のように植物を袋に包装することなくそのまま放置した例について説明する。図5は、水を含ませたパフカルに植物(ベゴニア、サンデリーナ)を根付かせたものをそのまま水を補給することなく放置したときの全体の重量の時間変化を示す。図5から明らかなように、3,4日経過した時点でいずれも苗の総重量が底をついた状態になっている。そして、表3に、各植物についての状態の変化を示す。
[Comparative Example 3]
As Comparative Example 3, an example in which a plant is left as it is without being packaged in a bag as in the example will be described. FIG. 5 shows the time change of the overall weight when a plant (Begonia, Sanderina) rooted in a puffal containing water is left without being replenished with water. As is clear from FIG. 5, the total weight of the seedlings is in a state where the bottom is attached at the time when 3 or 4 days have passed. And in Table 3, the change of the state about each plant is shown.
Figure JPOXMLDOC01-appb-T000004
Figure JPOXMLDOC01-appb-T000004
 表4から明らかなように、3,4日経過した時点で植物が枯死してしまっている。つまり、3,4日経過した時点の苗の総重量が底をついた状態とは、水分が植物と保水スポンジからほぼなくなって枯れた状態になったこと(つまり、保水スポンジ自体の重量と植物の繊維部分の重量のみ)を意味しており、外部に野ざらしで放置すると、栽培土又は培地から水が速やかに失われ、その結果、植物も枯れてしまうことがわかる。 As is clear from Table 4, the plants have died when 3 or 4 days have passed. In other words, when the total weight of the seedlings at the time when three or four days have passed has reached the bottom, the moisture has almost disappeared from the plant and the water-holding sponge (that is, the weight of the water-holding sponge itself and the plant It is understood that water is quickly lost from the cultivated soil or culture medium and, as a result, the plant also withers if left untreated outside.
〔比較例4〕
 比較例4として、表面2及び裏面3に用いるシートにいずれも透湿度加工を施さなかった例について説明する。図6は、図5と同様の苗を透湿度加工をしていない樹脂製シート(比較例1に用いたものと同じもので透水度は7.1g/m・24h)からなる袋に入れて密閉した状態にして水を補給することなく放置したときの苗の全体の重量の時間変化を示し、表5は各植物についての状態の変化を示す。
[Comparative Example 4]
As Comparative Example 4, an example in which the sheet used for the front surface 2 and the back surface 3 is not subjected to moisture permeability processing will be described. FIG. 6 shows that the same seedling as in FIG. 5 is put in a bag made of a resin sheet not subjected to moisture permeability processing (the same as that used in Comparative Example 1 and the water permeability is 7.1 g / m 2 · 24 h). Table 5 shows the change over time in the total weight of the seedlings when left in a sealed state without replenishing water, and Table 5 shows the change in state for each plant.

 図6から明らかなように、袋に入れて保管することで苗の総重量の変化を抑制できており、外部への水分の蒸発が防がれていることがわかる。ただし、この場合、ある程度の時間がたつと袋の内表面が曇りだし、やがてシートや袋内面に結露が生じ出してしまい、表5に示すように、その結露によって2週間以内には植物が腐り出す等の現象が起こる。つまり、植物を袋に入れて保管することで、植物の葉面、栽培土又は培地からの水の蒸発を抑制することはできるが、その分袋内に水蒸気が過度にこもってしまい、シートや袋内面に結露が生じて鑑賞性を損ない、さらには、その結露で雑菌が繁殖し、それが植物に感染した結果、植物を腐る等の不具合が起きる。 As is clear from FIG. 6, it can be seen that the change in the total weight of the seedling can be suppressed by storing it in a bag, and the evaporation of moisture to the outside is prevented. However, in this case, after a certain amount of time, the inner surface of the bag becomes cloudy and eventually condensation occurs on the sheet and the inner surface of the bag, and as shown in Table 5, the plant rots within two weeks due to the condensation. Phenomenon occurs. In other words, by storing the plant in a bag, it is possible to suppress the evaporation of water from the leaf surface of the plant, the cultivated soil or the culture medium, but the water vapor is excessively stored in the bag, and the sheet or Condensation occurs on the inner surface of the bag, thereby deteriorating the appreciation. Furthermore, as a result of the propagation of various germs due to the condensation and infecting the plant, problems such as rotting of the plant occur.
 このように、本実施形態の植物生育用袋1では、底部4を除く表面2及び裏面3が、透湿度が55~120g/m・24hである2枚の植物生育用シートを用いて形成されているため、その内部に収容する植物につき、水を補給することなく放置したときでも栽培土や培地に水を長期間保つことができ、少なくとも30~40日間の長期保存が可能になっている。そして、この場合、30~40日間おきに植物7の栽培土や培地に水を与えるようにすれば、さらに保存可能期間を延ばすことができる。 As described above, in the plant growth bag 1 of the present embodiment, the front surface 2 and the back surface 3 except the bottom 4 are formed using two plant growth sheets having a moisture permeability of 55 to 120 g / m 2 · 24 h. Therefore, even if the plant housed in the plant is left without being replenished with water, the water can be kept in the cultivation soil and medium for a long period of time, and long-term storage for at least 30 to 40 days becomes possible. Yes. In this case, the storage period can be further extended by supplying water to the cultivation soil and medium of the plant 7 every 30 to 40 days.
 また、本実施形態の植物生育用袋1は種々の形態で使用することができる。まず、水を与えることなく長期保存が可能であるため、観賞用として、植物を長期間放置しながら生育させるのに用いることができる。また、長期輸送させる場合など、植物を流通させる用途で用いても好適である。その他にも、長期の外出の際の保管用に用いても好適であり、例えば、平常時は植物生育用袋1に収容することなく植物を育てておき、長期(一か月)の外出の際に植物を植物生育用袋1に収容するといった形態で使用することもできる。 Moreover, the plant growth bag 1 of the present embodiment can be used in various forms. First, since it can be stored for a long time without giving water, it can be used for growing plants while standing for a long period of time. Moreover, it is suitable also for the use which distribute | circulates a plant, such as when carrying out long-term transportation. In addition, it is also suitable for storage for long-term outings. For example, plants are grown without being stored in the plant growth bag 1 in normal times, and long-term (one month) outings are possible. At this time, the plant may be used in such a form that it is housed in the plant growth bag 1.
 そのほか、上記では植物生育用シートを袋状にした植物生育用袋1について説明したが、植物生育用袋に成形することなく植物生育用シートの状態で使用することもできる。つまり、栽培土又は培地に根付いた植物をそのまま植物生育用シートでその周囲を覆って内部で植物を生育させる形態で使用することも可能であり、例えば鉢に植えた状態の植物をそのまま植物生育用シートで周囲を覆って包装するようにしてもよい。 In addition, although the plant growth bag 1 in which the plant growth sheet is formed into a bag shape has been described above, the plant growth sheet 1 can be used without being formed into a plant growth bag. In other words, it is also possible to use a plant rooted in the cultivated soil or culture medium as it is in a form in which the plant is grown as it is by covering the periphery with a plant growth sheet. For example, a plant planted in a pot is grown as it is. It is also possible to cover the periphery with a sheet for packaging.
 また、本実施形態の植物生育用袋1は、種々の大きさの植物に用いることができる。つまり、植物の大きさが大きい(小さい)ほど、植物や植物が根付いている栽培土や培地からの水蒸気の放出量も大きく(小さく)なるが、植物が大きい(小さい)分だけその植物の周囲を覆うのに使用する植物生育用シートも多く必要になって、その分だけ用いる植物生育用シートから放出される総水蒸気透過量(g/24h)も大きく(小さく)なって、結果的に植物側からの水蒸気の放出量と植物生育用シートから放出される総水蒸気透過量との間の均衡も保たれる。このように、植物の大きさが変わっても、結果的に、植物側からの水蒸気の放出量と植物生育用シートからの水蒸気の透過量との間の均衡が保たれるため、水を与えることなく長期保存が可能となる。 Also, the plant growth bag 1 of the present embodiment can be used for plants of various sizes. In other words, the larger (smaller) the size of the plant, the larger (smaller) the amount of water vapor released from the plant and the cultivated soil and medium in which the plant is rooted, but the larger the plant (smaller) the surroundings of the plant A large number of plant growth sheets used to cover the plant are also required, and the total water vapor transmission amount (g / 24h) released from the plant growth sheet used by that amount is increased (decreased). A balance is also maintained between the amount of water vapor released from the side and the total amount of water vapor transmitted from the plant growth sheet. In this way, even if the size of the plant changes, as a result, the balance between the amount of water vapor released from the plant side and the amount of water vapor permeated from the plant growth sheet is maintained, so that water is given. Long-term storage is possible without any problems.
 本実施形態の植物生育用シートにおける55~120g/m・24hという透湿度は、基本的には植物の大きさに応じた適切な範囲を覆うように用いることを想定したものであり、植物の輸送や観賞に適した範囲を植物生育用シートで覆うようにすれば、用いる植物生育用シート全体でみたときの水蒸気の透過量(g/24h)(用いる植物生育用シートの表面積(m)×透湿度(g/m・24h))が、対象の植物側から放出される水蒸気の量に対して特に適切な値になり、より好適な結果を発揮することができる。 The moisture permeability of 55 to 120 g / m 2 · 24 h in the plant growth sheet of this embodiment is basically assumed to be used so as to cover an appropriate range according to the size of the plant. If the range suitable for transportation and appreciation of the plant is covered with the plant growth sheet, the amount of water vapor permeation (g / 24h) (the surface area of the plant growth sheet used (m 2 )) ) × moisture permeability (g / m 2 · 24 h)) is a particularly suitable value for the amount of water vapor released from the target plant side, and more favorable results can be exhibited.
 なお、本実施形態では、植物生育用シートの透湿度に着目したものとなっているが、植物生育用袋1当たりの水蒸気透過量や植物の周囲を覆うのに用いる植物生育用シート全体の水蒸気透過量に主点を置いて、水蒸気透過量という観点から植物生育用袋1を作成したり、植物の周囲を覆うのに用いる植物生育用シートの種類や使用する面積を決定するようにしてもよい。例えば、実施例の植物育成用袋1(145mm×300mmのシートを両面に用いたもの)と同程度かそれに近い大きさの袋、又はシートを作成する場合には、55~120g/m・24hという透湿度の範囲に対応する範囲として、4.8~10.5g/24hという値の水蒸気透過量となるように製造してもよい。 In this embodiment, the moisture permeability of the plant growth sheet is focused. However, the water vapor permeation amount per plant growth bag and the water vapor of the whole plant growth sheet used to cover the periphery of the plant. Focusing on the permeation amount, the plant growth bag 1 may be created from the viewpoint of water vapor permeation amount, or the type and area of the plant growth sheet used to cover the periphery of the plant may be determined. Good. For example, in the case of making a bag or sheet having a size similar to or close to that of the plant-growing bag 1 of the example (using a sheet of 145 mm × 300 mm on both sides), 55 to 120 g / m 2 · As a range corresponding to the moisture permeability range of 24 h, the water vapor transmission amount may be 4.8 to 10.5 g / 24 h.
 本明細書において開示された実施形態は全ての点で例示であって、本発明の範囲はそれらによって限定されることはないと理解されるべきである。当業者であれば、本発明の趣旨を逸脱しない範囲で、適宜改変が可能であることを容易に理解できるであろう。従って、本発明の趣旨を逸脱しない範囲で改変された別の実施形態も、当然、本発明の範囲に含まれる。 It should be understood that the embodiments disclosed herein are illustrative in all respects and that the scope of the present invention is not limited thereby. Those skilled in the art will readily understand that modifications can be made as appropriate without departing from the spirit of the present invention. Accordingly, other embodiments modified without departing from the spirit of the present invention are naturally included in the scope of the present invention.
