【発明の属する技術分野】
本発明は、生分解性素材で筒状に形成したものであって、主として砂丘や砂漠地等の砂地に樹木の苗を植え付けたり、長芋・牛蒡・長大根のような長尺根菜類の苗を植え付けて砂地で育成するために、苗とともに砂地中に埋め込んで使用する植物育成用の容体に関するものである。
【０００２】
【従来の技術】
従来から、花卉や野菜類の育苗のために広く使用されている育苗ポットは、周知のごとく黒色の塩化ビニール製薄膜シートをブロー成形手段等によって小さな植木鉢形に膨出成形したものや、樹木苗の挿し木や育成には、土中への直播きや直挿しか樹脂製や素焼き製の植木鉢が使用されている。
【０００３】
【発明が解決しようとする課題】
しかしながら、薄い合成樹脂シート製の育苗ポットや樹脂製の植木鉢にあっては、ポット壁や鉢壁から吸気・吸水や栄養分を吸収することができないため、根が蒸れ易く、潅水による養分補給を待たなければならないため、所定の大きさ以上には生育しにくくなり、成長が停滞し、素焼き鉢の場合をも含め、他の大形鉢や畑地等への植え替え時には育苗土を育苗ポットや鉢から取り出す必要があり、この植え替え作業時に育成苗や挿し木の根が損傷し易く、植え替え後の成育に一時的な成長障害を来すことが避けられない。また、薄い合成樹脂シート製育苗ポットや樹脂製植木鉢にあっては、使用後不要となったときの廃棄処分が大気汚染や土壌汚染のような環境汚染や公害問題を引き起こすという懸念も存在するものであった。
【０００４】

【００１７】
【実施例】
図は、本発明にいうところの植物育成用容体についての一実施例形態を説明する図であって、図１は、筒本体１と底部材１１とを示す正面上方向から見た斜視図。図２は、薄膜筒体２の製造手段を示す正面上方向から見た斜視図。図３は、薄膜筒体２を示す正面上方向から見た斜視図。図４は、筒本体１と薄膜筒体２との合体手段を示す正面上方向から見た斜視図。図５は、筒本体１の外周に薄膜筒体２を外嵌させて二層構造とした状態を示す正面上方向から見た斜視図である。
【００１８】
先ず、第１実施例として、樹木苗の育成に使用するのに適した植物育成用容体についての素材と製造手段について説明する。該植物育成用容体の筒本体１を製造する素材例としては、竹を打圧圧壊して得た煮沸されていない竹繊維約２０重量部と、煮沸した葦の繊維約４０重量部と、シュロやヤシのような熱帯植物からなるパーム（palm）繊維約４０重量部とを主体成分として混合した植物繊維素材に対して、蕎麦殻又は茶殻若しくはそのそれぞれを焙煎して炭化させたものを約１０重量部前後と、尿素約１０重量部（必要に応じて窒素、リン酸等のほか、マグネシウムやマンガン、硼素等も加えればよい）と、竹酢液又は木酢液若しくはその両液を約５重量部とを混入し、適量の水を加えて全体を均一に撹拌混合し泥状に練ったものを成型用素材とする。
【００１９】
この成型用素材を、吸湿軟化状態程度となるまで予め余分な水分を除去して圧縮成型金型に入れ、温度２００℃、圧力３Ｋｇ／ｃｍ²の条件下で２０〜３０秒かけてプレス成形させ、図１にみられるような所要径、所要肉厚、所要長さの円筒体１と、所要肉厚の円盤形底部材１１とを形成する。その大きさの一例としては、外径１００mm、内径９０mm、即ち筒壁１ａの肉厚５mm、長さ３００mmとした円筒体１と、肉厚５mm、直径９０mmとした円盤形底部材１１とを形成する。この底部材１１には円盤の中央部に１０mmの水抜き穴１２を形成してあるものとする。この底部材１１を円筒体１の一方の開口部（同図において下方の開口部）に押圧状に嵌め込む。
【００２０】
このようにして形成された円筒体１は、その表面に微細な凹凸を有し、水分や空気が浸透する微細な孔を備えている。また、時間の経過とともに微生物によって生分解する性質を備えている。それ自体分解とともに育成苗に対する栄養素としての役割を果たす。
【００２１】
次に、図２及び図３に基づいて、薄膜筒体２を製造する素材例について説明すると、前記のように、ポリ乳酸、ポリカプロラクトン、ポリブチレンサクシネート、ポリエチレンサクシネート、ポリビニールアルコール等の生分解性を備えた素材で形成した不織布３ａを用いる。ここでは、例えば乳酸ポリマーの不織布３ａを図２のように二つ折りとし、その内長が前記円筒体１の外周面の長さにほぼ見合う長さ、即ち、前記事例では１００mm×π（円周率）＋α（付加量）の箇所で長さ３００mm縫製２ｂし、縫い代を加えた長さ部分で裁断したものと、別途円盤形に裁断した素材３ｂを底部材２１として、前記縫い代部分と縫い合わせて、図３のように、筒状となるように形成する。この底部材２１も、その円盤中央部に×形の水抜き用切り込み２２を形成してあるものとする。
【００２２】
このようにして形成した薄膜筒体２も、薄膜の不織布であることと素材原料との関係で透水性と生分解性とを備えている。この生分解期間は、筒本体１に比して長期間維持するように設定されている。
【００２３】
次いで、図４に示したように、この薄膜筒体２に対して矢印のように筒本体１を挿入することにより、図５に示したように、筒本体１の外周に薄膜筒体２を外嵌させて内外二層構造に形成した植物育成用容体が得られる。
【００２４】
このようにして得た植物育成用容体は、地上において使用する場合の苗育成土投入後の形状維持期間を、例えば、筒本体１を平均６０日〜８０日、薄膜筒体２を平均２．５年〜３年に設定し、地中に埋め込んだ生分解期間を、例えば、筒本体１を平均２５日〜４０日、薄膜筒体２を平均２年〜２．５年に設定し、何れの場合も、筒本体１に比し薄膜筒体２の生分解期間を長期間維持するように設定しておく。
【００２５】
以上本発明の代表的と思われる実施例について説明したが、本発明は必ずしもこの実施例に示した素材のみに限定されるものではなく、他の繊維素材や肥料等を適宜付加して実施することができるものであって、本発明にいう構成要件を備え、かつ、本発明にいう前記の目的を達成し、以下にいう効果を有する範囲内において適宜改変して実施することができるものである。
【００２６】
【発明の効果】
以上の説明から明らかなように、本発明にいう植物育成用容体は、樹木苗の育成の場合は、地中への植え込みを終えるとそのままにしておくことによって、筒本体及び薄膜筒体がともに育成樹木の生育とともに自然分解し、樹木の肥料として作用し成長を促進させることができる。また、例えば長芋や牛蒡、長大根のような長尺の根菜類を育成する場合は、地中においてその生育とともに筒本体が自然分解し肥料として作用し、薄膜筒体は根菜類の形状を異常に変形しないように規制する作用をなす。また、収穫時には薄膜筒体を引き抜くことによって、収穫根菜類を痛めることなく収穫することができる。殊に、栄養素が少なく乾燥の激しい砂地において、樹木の植林に役立ち、根菜類の収穫を行うことに役立つという従来の育苗ポットや植木鉢では到底期待することができなかった顕著な効果を発揮するものである。
【００２７】
また、本発明にいうところの植物育成用容体は、筒本体を構成する主体素材が繊維であるため、植物育成用容体が微細な気孔を有しているので、根を張り易く、地上にあっては苗根が蒸れることなく健康に生育し、地中に配置する場合をも含めて、苗の根が筒本体の繊維内に直接食い込んで根張りの良い状態で安定良く継続的に生育させることができる効果がある。しかも、主体素材としての植物繊維は、廃材として原野に放置されている未利用材や廃棄植物の繊維を再利用し、薄膜筒体を含めて容体全体が利用後は土に返すことができるので、環境浄化の一助となるという効果をも有するものである。

[0019]
This molding material is preliminarily removed from excess moisture until it is in the hygroscopic softened state, put into a compression mold, and press molded at a temperature of 200 ° C. and a pressure of 3 kg / cm ² for 20 to 30 seconds. A cylindrical body 1 having a required diameter, a required wall thickness, and a required length as shown in FIG. 1 and a disk-shaped bottom member 11 having a required wall thickness are formed. As an example of the size, a cylindrical body 1 having an outer diameter of 100 mm and an inner diameter of 90 mm, that is, a wall thickness of 5 mm and a length of 300 mm, and a disk-shaped bottom member 11 having a thickness of 5 mm and a diameter of 90 mm are formed. To do. The bottom member 11 has a 10 mm drain hole 12 formed in the center of the disk. The bottom member 11 is fitted into one opening (the lower opening in the figure) of the cylindrical body 1 in a pressing manner.
[0020]
The cylindrical body 1 formed in this way has fine irregularities on its surface and has fine holes through which moisture and air permeate. It also has the property of biodegrading by microorganisms over time. It itself plays a role as a nutrient for growing seedlings along with decomposition.

As is clear from the above description, the plant-growing container according to the present invention, in the case of growing tree seedlings, is left as it is after planting in the ground, so that both the tube main body and the thin film tube body Naturally decomposes along with the growth of the cultivated tree and can act as a fertilizer for the tree to promote growth. Also, for example, when growing long root vegetables such as long bean, beef bowl and daikon radish, the tube body naturally decomposes as it grows in the ground and acts as a fertilizer. It acts to regulate so as not to deform. Moreover, by harvesting the thin film cylinder at the time of harvesting, it is possible to harvest without damaging the harvested root vegetables. In particular, it is effective in planting trees and harvesting root vegetables on sandy soils with low nutrients and high dryness. It is.

Further, in the plant growing container referred to in the present invention, since the main material constituting the cylinder body is a fiber, the plant growing container has fine pores, so that it is easy to have roots, and is suitable for the ground. The seedling root grows healthy without being steamed, and the root of the seedling eats directly into the fiber of the tube body, including the case where it is placed in the ground, and it grows stably and continuously in a well-rooted state. There is an effect that can. In addition, plant fibers as the main material can be reused from unused materials left in the wild as waste materials and fiber from discarded plants, and the entire container, including thin-film cylinders, can be returned to the soil after use. It also has the effect of helping to purify the environment.
