Description
【0001】[0001]
本考案は園芸用のシートに係わり、特に栽培する植物の葉裏に優しい乱反射光 を当てる様にする為の園芸用可撓性シートに関するものである。 The present invention relates to a horticultural sheet, and more particularly to a horticultural flexible sheet for applying gentle diffused light to the underside of a plant to be cultivated.
【0002】[0002]
従来光反射性のシート等を植物の栽培に用いる例としては、例えば特開昭63 −137621号に開示されているような保温断熱性が良く、作物の成育や果房 の色づき促進を目的とするものがある。 又多孔性のフィルムを植物の栽培に用いる例としては、例えば実開昭61−1 91763号に開示されているような可視光を透過させるが赤外線は透過せず、 保温能力が大きく、除湿効果に優れた温室用被覆材を提供するものがある。 更に特開昭63−81038号には、近赤外光の反射フィルム層と、光吸収黒 色フィルム層からなる積層フィルムであって、該フィルム中に空気層を有する断 熱性、遮光性のマルチングフィルム或いはハウス用フィルムが提案されている。 然しこれらのもので、所謂マット灌水や底面灌水システムと呼ばれる園芸方法 に用いて、植物の成長を促進する為に応用出来るものは無い。この為本考案者等 は先に実願平4−79704号にて光反射性の園芸用可撓性シートを提案したが 、本考案は更にこれを改良したものである。 As an example in which a light-reflective sheet or the like is conventionally used for cultivating a plant, for example, the heat insulating and heat insulating property as disclosed in JP-A-63-137621 is good, and the purpose is to promote the growth of crops and the coloring of fruit clusters. There is something to do. As an example of using a porous film for cultivating plants, for example, visible light as disclosed in Japanese Utility Model Laid-Open No. 61-191763 is transmitted but infrared rays are not transmitted, which has a large heat retaining ability and a dehumidifying effect. To provide excellent greenhouse coating materials. Further, JP-A-63-81038 discloses a laminated film comprising a near-infrared light reflecting film layer and a light-absorbing black film layer, which has an air layer in the film, and has a heat insulating property and a light shielding property. Films or films for house have been proposed. However, none of these can be used for horticultural methods, so-called mat irrigation or bottom irrigation systems, to promote plant growth. Therefore, the present inventors previously proposed a light-reflecting flexible sheet for gardening in Japanese Patent Application No. 4-79704, but the present invention is a further improvement thereof.

本考案は、植物の葉裏につくアブラムシ・ダニ類等の害虫の生息を防止し、葉 の徒長を防いで植物そのものの成長を促進する為の園芸用可撓性シートを提供す るものであり、特に底面灌水システムやマット灌水システムと呼ばれる園芸方法 に於いて、鉢の下に敷くことによりその表面の光反射性を利用して葉の裏側等葉 の全面から光が照射されるようにしたものである。本考案の可撓性シートは鉢の 下に敷くにもかかわらず、鉢の下に敷いた本考案の園芸様可撓性シートの裏側( 下側)からの灌水が支障無く行われるだけで無く、成長する植物の根が鉢の下部 (灌水用の穴等)から外に張り出した場合には、本考案の可撓性シートの穴に潜 り込むことが無い為、作業性にも優れた園芸用可撓性シートを提供するものであ る。 The present invention provides a flexible horticultural sheet for preventing the infestation of aphids, mites and other harmful insects on the underside of plants, preventing leaf overgrowth and promoting the growth of the plants themselves. In particular, in the horticultural method called bottom irrigation system or mat irrigation system, it is laid under the pot so that the light is reflected from the entire surface of the leaf such as the back side of the leaf. It was done. Even though the flexible sheet of the present invention is laid under the pot, not only does the irrigation from the back side (lower side) of the horticultural-like flexible sheet of the present invention laid under the pot be performed without any trouble. Also, when the roots of the growing plant extend outside from the bottom of the pot (such as holes for watering), they do not go into the holes of the flexible sheet of the present invention, so workability is also excellent. A flexible sheet for gardening is provided.

本考案の園芸用可撓性シートは、少なくとも片側の表面が光反射性を有する可 撓性のシートであって、該シートの表裏何れの側からも水の透過が可能であるが 、植物の根の透過は妨げるような微孔を多数設けたことを特徴とする園芸用可撓 性シートであり、又該シートに設けられる微孔の密度は、1,000 〜1,000,000 個 /m2 となる様に略均一開けられた孔であることを特徴とする園芸用可撓性シー トを提供するものである。又、本考案の園芸用可撓性シートに入射する光の反射 は、ランダムな方向に乱反射して、葉裏の色々な部分に出来る限り万遍なく当た る様にする為に、用いる園芸用可撓性シートの表面に凹凸模様を付与したり、該 シートが多層構造で光の反射面が中間層である場合には、光の反射面となる中間 層の表面に凹凸模様を付与することでこの効果をより充分に発揮するようにした ものである。The flexible horticultural sheet of the present invention is a flexible sheet having a light-reflecting property on at least one surface, and water can be transmitted from both front and back sides of the sheet. It is a flexible sheet for gardening characterized by providing a large number of micropores that prevent the penetration of roots, and the density of the micropores provided in the sheet is 1,000 to 1,000,000 pieces / m 2 . The present invention provides a flexible sheet for horticulture, which is characterized in that the holes are substantially evenly opened. The reflection of light incident on the flexible horticultural sheet of the present invention is irregularly reflected in random directions so that various parts of the underside of the leaf are evenly distributed as much as possible. If the sheet has a multilayer structure and the light reflecting surface is an intermediate layer, the surface of the intermediate layer that serves as the light reflecting surface is provided with an uneven pattern. By doing so, this effect is fully exerted.
【0005】 即ち本考案の園芸用可撓性シート(3)は、例えばポリプロピレン、ポリエチ レン、ポリエステル、ポリアミド、弗素樹脂等の耐薬品性や肥料に対する耐久性 、耐侯性のある素材の単独フィルム又はこれらの材質を複数枚積層して接着した フィルム等からなるシート(1)の少なくとも片面、アルミ蒸着等を施して光反 射性を付与した層(2)或いはその中間層に用いるフィルムの積層前にアルミ蒸 着等を施して光反射性を付与した層を設けた可撓性シートに、水は透過するが、 植物の根は透過しない微孔(4)を多数開けたもの等であって、必要に応じてエ ンボス等の方法により表面に凹凸模様(5)を付与することにより、本考案の可 撓性シートを敷いてあっても上に載せる鉢に底面からの十分な灌水が可能で、且 つ光線を乱反射する機能を有する様にしたものである。That is, the horticultural flexible sheet (3) of the present invention is, for example, a single film of a material having chemical resistance such as polypropylene, polyethylene, polyester, polyamide, and fluororesin, durability against fertilizer, and weather resistance. Before lamination of the film used for at least one surface of a sheet (1) made of a film or the like obtained by laminating and adhering a plurality of these materials, a layer (2) provided with light reflectivity by performing aluminum vapor deposition or an intermediate layer thereof A flexible sheet provided with a layer that is light-reflecting by aluminum vapor deposition, etc., has a large number of micropores (4) that penetrate water but not plant roots. By adding an uneven pattern (5) to the surface by a method such as embossing, if necessary, even if the flexible sheet of the present invention is laid, sufficient watering from the bottom is possible in the pot to be placed on top. And It has a function of irregularly reflecting light rays.
【0006】 本考案に用いる可撓性シートに必要な特性としては、上記基本的機能の他に園 芸用に使用する為コストがかからない事と、簡単に破損せずに軽く扱い易いと言 う特性も重要となる。この為種々の材料にて試行錯誤を繰り返した末に、厚さ1 0〜30μ程度の市販のポリプロピレン製フィルム、ポリエチレン製フィルム、 アルミニウム蒸着ポリプロピレンフィルム等を複数枚重ねてそれぞれをドライラ ミ方式等にて接着して、約40〜100μ程度の厚さ(より好ましくは55〜8 0μ程度の厚さ)の積層フィルムとしたものを用いて微孔を開けたものが、安価 で且つ必要とする機能を満たす為に非常に有用であることを見出した。 しかし 微孔の開け方によって、即ち孔の散布状態(密度)や孔の大きさによって引裂強 度等の物性が大きく変化してしまう為に、園芸用可撓性シートとして適用し得る 条件が材質の選択と共に重要な要素となる。In addition to the basic functions described above, the flexible sheet used in the present invention requires no cost because it is used for horticultural purposes, and it is easy to handle without light damage. Characteristics are also important. Therefore, after repeated trial and error using various materials, multiple commercially available polypropylene films, polyethylene films, aluminum vapor-deposited polypropylene films, etc., with a thickness of about 10 to 30μ are stacked, and each is subjected to a dry lamination method or the like. It is an inexpensive and necessary function to make fine holes by using a laminated film having a thickness of about 40 to 100 μ (more preferably a thickness of about 55 to 80 μ) that is bonded by adhesion. It has been found to be very useful for satisfying. However, because the physical properties such as tear strength change greatly depending on how to open the micropores, that is, the scattering state (density) of the pores and the size of the pores, the conditions applicable to the flexible gardening sheet are the materials. Will be an important factor along with the choice of.
【0007】 種々の実験結果により得られた好適例としては、ポリエチレン樹脂フィルムを 間に挟んで、アルミニウム蒸着ポリプロピレン樹脂フィルムとポリプロピレン樹 脂フィルムとをドライラミした積層フィルムに、0.1〜1.5mmの孔を10 00〜1000000個/m2 に略等間隔に開けたものがあげられる。当然のこ とながら、孔の径が小さければ孔の数を増やしても一定の強度は保たれるが、孔 の径が大きくなれば孔の数を減らして一定の間隔を保つ様にしないと、強度が落 ちて破れ易く実用価値が無くなってしまう。 又底面灌水に使用することから、水の吸い上げ効果等を考えれば孔径は0.5 mm以上あることが好ましく、又根が透過しない為には1.3mm以下であるこ とが都合良い。A preferred example obtained by various experimental results is 0.1 to 1.5 mm in a laminated film obtained by dry laminating an aluminum vapor-deposited polypropylene resin film and a polypropylene resin film with a polyethylene resin film sandwiched therebetween. The holes of 100 to 1,000,000 holes / m 2 are formed at substantially equal intervals. As a matter of course, if the diameter of the holes is small, the strength can be kept constant even if the number of the holes is increased, but if the diameter of the holes is increased, the number of the holes must be reduced to keep a constant interval. However, the strength is reduced and it is easy to tear and loses practical value. Further, since it is used for irrigating the bottom surface, the pore diameter is preferably 0.5 mm or more in consideration of the effect of sucking up water, and it is convenient that it is 1.3 mm or less so that the roots do not penetrate.
【0008】 また、本考案に用いる素材であるアルミ蒸着ポリプロピレン樹脂フィルムにエ ンボッシングして表面に凹凸模様(5)をつけてからポリエチレン樹脂フィルム を挟んでポリプロピレン樹脂フィルムとをドライラミして積層したり、或いはポ リエチレン樹脂フィルムを間に挟んで、アルミニウム蒸着ポリプロピレン樹脂フ ィルムとポリプロピレン樹脂フィルムとをドライラミした積層フィルムにエンボ ッシングしてフィルム全体に凹凸をつけたものを用いると、入射した光線を乱反 射する為に葉裏に万遍なく光線が当たって、光線の当たらない影の部分が減少す る為に、本考案の効果は特に顕著にあらわれる。この時の凹凸模様は、光線を乱 反射させる為のものであるから、出来ればランダムな柄の様に光線が乱反射し易 い柄であって、一定以上の深さを有し、個々の凸部間(若しくは凹部間)が空き 過ぎる大柄なものや、逆に個々の凸部間(若しくは凹部間)が詰り過ぎている様 な、細か過ぎる柄は不適当である。本考案者等の実験では、エンボス後の全体の 厚みが、エンボス前の状態の1.3倍以上より好ましくは1.6倍以上となる様 な深さの柄が好適であった。これ以上浅い柄の場合には、エンボス柄を施さない ものと、効果の差が殆ど見られなかった。又柄の深さは、少なくともエンボス後 の厚さがエンボス前の厚さの3倍迄は問題無く項結果が得られた。In addition, the aluminum vapor-deposited polypropylene resin film, which is the material used in the present invention, is embossed to form a concavo-convex pattern (5), and then the polyethylene resin film is sandwiched between the polypropylene resin film and dry laminated to be laminated. Alternatively, if a polyethylene resin film is sandwiched between the aluminum vapor-deposited polypropylene resin film and the polypropylene resin film and the laminate film is embossed on the laminated film to make the entire film uneven, incident light rays are disturbed. The effect of the present invention is particularly remarkable because the light rays hit the underside of the leaf evenly due to the reflection, and the shadow portion where the light rays do not hit decreases. Since the uneven pattern at this time is to diffusely reflect the light rays, it is a pattern in which the light rays are likely to be diffusely reflected, such as a random pattern if possible. It is inappropriate to use a large pattern with too large spaces between parts (or recesses) or, on the contrary, too small a pattern with too large spaces between individual projections (or recesses). In an experiment conducted by the present inventors, a handle having a depth such that the total thickness after embossing is 1.3 times or more, and more preferably 1.6 times or more, that of the state before embossing is suitable. When the pattern was shallower than this, there was almost no difference in effect from the one without the embossed pattern. As for the depth of the handle, at least the thickness after embossing was up to 3 times the thickness before embossing, and the result was obtained without any problem.

本考案の園芸用可撓性シートの使用方法としては、例えば灌水マットの上に光 反射面を上向きにして敷き、その上に園芸用鉢を載せて植物を栽培することによ り、灌水マットから本考案の園芸用可撓性シートを通して鉢に給水したり肥料を 供給することができ、且つ光反射面に当たった光の乱反射により園芸植物の葉の 裏側にも十分な光を当てることができる。一方、鉢の底部の給水部等から鉢の外 に伸びてくる根は、本考案の園芸用可撓性シートの孔に潜りこもうとするが、根 が透過出来ない大きさに設定されている為に、フィルムの孔に絡みついたり、孔 を通過して下のマットに絡みつくことが無いので、出荷その他で鉢を動かす時に も根の損傷を心配する必要が無く、作業性が非常に良いものである。 The flexible sheet for horticultural use of the present invention can be used, for example, by laying a light-reflecting surface upward on a watering mat and cultivating a plant by placing a pot for gardening on the watering mat. It is possible to supply water to the pots and to supply fertilizers through the flexible sheet for gardening of the present invention, and it is possible to apply sufficient light to the back side of the leaves of the garden plant due to the irregular reflection of the light hitting the light reflecting surface. it can. On the other hand, the roots extending from the water supply part at the bottom of the pot to the outside of the pot will try to dive into the holes of the flexible horticultural sheet of the present invention, but the size is set so that the roots cannot penetrate. Since it does not get entangled in the hole of the film or entangled with the mat below after passing through the hole, there is no need to worry about damage to the root when moving the pot during shipping etc., and workability is very good It is a thing.
