使用されるシート、或いは、熱線を吸収して地温を高め
、かつこれを保持するシート等があるが、これ等のシー
トは、価格を安くするため、それぞれ、１つの目的のた
めの機能しか持たないのが一般的である。Popular agricultural sheets include so-called light-reflecting sheets used to improve the color and quality of fruits, sheets used to control the amount of light entering greenhouses, etc., and sheets used to control the amount of light entering greenhouses, etc. There are sheets that absorb and maintain soil temperature, but in order to keep the price low, these sheets generally only have one function.
しかしながら、果実等を栽培する場合には、果実の質向
上と共に果樹の成育をも促進することが大切であり、こ
のためには、光を反射すると同時に太陽熱を吸収し地温
を高め得るものが必要である。However, when cultivating fruits, etc., it is important to improve the quality of the fruits as well as promote the growth of fruit trees, and for this purpose, it is necessary to have something that can reflect light and at the same time absorb solar heat and raise the soil temperature. It is.
従来も、この様なものが開発されてはいたが、構造が複
雑で高価であり、しかも、それぞれの機能が１つの目的
を持つものに比べ低下する欠点があった。Although such devices have been developed in the past, they have the disadvantage that they are complicated and expensive, and each function is lower than that of a device with a single purpose.
本考案は、上記の問題を解決するために提案されたもの

第１図に示すように、本考案の農業用シート１は、熱吸
収性と耐水性を有する基材２と、接着剤層３と、アンカ
ーコート層４と、金属薄膜層５及びこの薄膜層を保護す
る透明な表面保護層６によって形成されている。As shown in FIG. 1, the agricultural sheet 1 of the present invention includes a base material 2 having heat absorbing properties and water resistance, an adhesive layer 3, an anchor coat layer 4, a metal thin film layer 5, and this thin film layer. It is formed by a transparent surface protection layer 6 that protects the surface.
前記基材２は、ポリエチレン、ポリプロプレン等にカー
ボンブラック等の黒色又はそれに近い色の顔料を混入し
、熱吸収性を高めたフィルム又はシートである。The base material 2 is a film or sheet made by mixing polyethylene, polypropylene, or the like with a pigment of black or a color close to black, such as carbon black, to improve heat absorption.
前記表面保護層６は、両光、耐候、耐水性の良好な樹脂
、例えばポリプロピレン、ポリエステル等のフィルムよ
り戒り、金属薄膜層５は、このフイルムに、アルミニウ
ム又は光反射性の良好な金属を好ましくは４００〜５０
０大の厚さに蒸着したものである。The surface protective layer 6 is made of a film made of a resin with good light, weather resistance, and water resistance, such as polypropylene or polyester, and the metal thin film layer 5 is made of a film made of a resin with good light, weather resistance, and water resistance, such as polypropylene, polyester, etc., and the metal thin film layer 5 is made of a film made of aluminum or a metal with good light reflection properties. Preferably 400-50
It was deposited to a thickness of 0.
４００Δ以上であると、太陽のほとんど全部を反射する
ことができる。When it is 400Δ or more, almost all of the sunlight can be reflected.
次に、接着剤層３は、例えはポリエチレン、ポリプロピ
レン、エチレン−酢酸ビニル、エチレン−アクリル酸、
エチレン−アクリル酸エステル等の共重合物あるいはア
イオノマー等より成る。Next, the adhesive layer 3 is made of, for example, polyethylene, polypropylene, ethylene-vinyl acetate, ethylene-acrylic acid,
It consists of a copolymer such as ethylene-acrylic acid ester or an ionomer.
なお、アンカーコート層４は、接着剤層３の接着強度を
高めるために設けられているが、省略することもできる
。Although the anchor coat layer 4 is provided to increase the adhesive strength of the adhesive layer 3, it can also be omitted.
上記のような構成のシート１に、さらに凹凸を設ける。The sheet 1 configured as described above is further provided with irregularities.
この凹凸は、例えばシート１全体に設けられたり（第１
図）、或は第２図のように、金属薄膜層５を設けた表面
保護層６に予め凹凸を形成したのち、基材２と貼り合せ
てもよい。This unevenness may be provided, for example, on the entire sheet 1 (the first
), or as shown in FIG. 2, the surface protection layer 6 provided with the metal thin film layer 5 may be formed with unevenness in advance and then bonded to the base material 2.
なお、シート１に適当な小孔７をあけておくことができ
る。Incidentally, a suitable small hole 7 can be made in the sheet 1.
第３図及び第４図は他の実施例を示すものであり、金属
薄膜層５は、アルミニウム箔又はその他の光反射性の良
好な金属箔であってもよい。FIGS. 3 and 4 show other embodiments, and the metal thin film layer 5 may be an aluminum foil or other metal foil with good light reflectivity.
この場合は、当然蒸着膜よりも厚みが充分厚くなる。In this case, the thickness will naturally be sufficiently thicker than the deposited film.
この様な箔を用いた場合には、第３図のように、表面に
コート剤或いはポリプロピレン、ポリエステル、ポリエ
チレン等の防食被膜層８を形成し金属薄膜層を保護する
。When such a foil is used, as shown in FIG. 3, a coating agent or an anticorrosion coating layer 8 of polypropylene, polyester, polyethylene, etc. is formed on the surface to protect the metal thin film layer.
なお、金属薄膜層の保護は、第４図に示すように、前記
表面保護層６によって行ってもよい。Note that the metal thin film layer may be protected by the surface protection layer 6, as shown in FIG.
また、第２図と同様、アンカーコート層を省略し、基材
２と金属薄膜層５を接着することもできる。Further, as in FIG. 2, the anchor coat layer can be omitted and the base material 2 and the metal thin film layer 5 can be bonded together.
なお、凹凸の形成の仕方は、第１図及び第２図の場合と
同様である。Note that the method of forming the unevenness is the same as in the case of FIGS. 1 and 2.
要は、金属薄膜層に当った光が乱反射するようにしてお
けばよい。The point is that the light hitting the metal thin film layer should be diffusely reflected.
本考案に係る農業用シートは以上の様な構成であって、
これを使用する場合、表面保護層６を上にすると、凹凸
を有する金属薄膜層５によって太陽光線が乱反射され、
従ってこれを果樹周辺に敷きつめておくと、従来のよう
に、果実の下面のみでなく日陰になる側面にも充分に自
然光が当たり、果実の育成に好影響を与える。The agricultural sheet according to the present invention has the above structure,
When using this, when the surface protective layer 6 is placed on top, the sun's rays are diffusely reflected by the metal thin film layer 5 having unevenness.
Therefore, if this is spread around fruit trees, sufficient natural light will reach not only the underside of the fruit but also the shaded sides, as in the conventional method, and this will have a positive effect on the growth of the fruit.
さらに、保護層６の表面積が凹凸によって増加し、シー
トの受熱量が多くなって、これが地表に伝わるため、果
樹の成育により良い影響を与える。Furthermore, the surface area of the protective layer 6 increases due to the unevenness, and the amount of heat received by the sheet increases, which is transmitted to the ground surface, which has a better effect on the growth of fruit trees.
同様に、温室の屋根等を用いると室温が上昇し、直射日
光に弱い野菜等が保護される。Similarly, using the roof of a greenhouse raises the room temperature and protects vegetables etc. that are sensitive to direct sunlight.
また、シート１を裏返すと、熱吸収性の良好な基材２に
よって熱が吸収され地温が上昇する。Further, when the sheet 1 is turned over, heat is absorbed by the base material 2 having good heat absorption properties, and the ground temperature increases.
しかも、地表からの輻射熱は、下側になった反射面によ
って遮られ放散しないので地温が保持される。Moreover, the radiant heat from the ground surface is blocked by the lower reflective surface and does not dissipate, so the ground temperature is maintained.
以上の様に、本考案の農業用シートは極めて優れた効果
を有する。As described above, the agricultural sheet of the present invention has extremely excellent effects.
