Description

本発明は、日除け用シート、日除け用シートの製造方法、及び日除け用シートの使用方法に関する。 The present invention relates to a sunshade sheet, a method for manufacturing a sunshade sheet, and a method for using the sunshade sheet.

地球温暖化やオゾン層破壊による太陽光の強さが植物栽培にも悪影響を及ぼすようにより、植物においても日差し、暑さ対策が必要になってきており、農の現場では土の温度低下が望まれている。従来のマルチングは平面のプラスチック製のシートで通気性がなく土の温度の高温化が避けられない。寒冷紗も日除けとして使用されることがあるが、目が粗いと遮光率が低く、土の温度低下に寄与しない。 As the intensity of sunlight due to global warming and ozone layer depletion adversely affects plant cultivation, it is becoming necessary to take measures against sunlight and heat in plants, and it is hoped that the temperature of soil will drop at farm sites. It is rare. Conventional mulching is a flat plastic sheet that is not breathable and the temperature of the soil is inevitably high. A lawn cloth may also be used as a shade, but if the eyes are coarse, the shading rate is low and it does not contribute to the temperature drop of the soil.

連通気泡が複雑に曲がり通じているスポンジ状発泡体を平板状に形成し、表面部から裏面部への通気及び通水を可能としながら遮光性を持たせた防草シート（特許文献１）や、通気性且つ透水性の細孔を備えた合成樹脂製の透明又は半透明のフィルム又はシートからなる農業用シート（特許文献２）も開示されているが、簡単な構成で、通気性を確保しつつ日差しを効果的に遮ることができる日除け用シートが求められている。 A weed-proof sheet (Patent Document 1) in which a sponge-like foam in which communicating bubbles are bent in a complicated manner is formed into a flat plate shape to allow ventilation and water flow from the front surface portion to the back surface portion while providing a light-shielding property. Agricultural sheets (Patent Document 2) made of a transparent or translucent film or sheet made of synthetic resin having breathable and water-permeable pores are also disclosed, but the simple configuration ensures breathability. However, there is a demand for a sunshade sheet that can effectively block the sunlight.

By forming the portion and the valley portion, the three-dimensional awning sheet 1 can be easily manufactured.

図３は、図１の日除け用シート１の平面図である。本発明の実施形態の日除け用シート１は、平面視した場合に、シート１０の切れ込み１４，１５，３４，３５が開いて切れ込み１４，１５，３４，３５を画成するシート１０の部分により形成される開口１４ａ，１５ａ，３４ａ，３５ａを除き、殆どがシート１０の面積により占められている。日除け用シート１を使用時の立体構造にした状態で平面視した日除け用シート１の外形の面積に対するシート１０が占める面積、言い換えると平面視した日除け用シート１の外形の面積に対する開口１４ａ，１５ａ，３４ａ，３５ａを除く面積は８０％以上、好ましくは９０％以上である。このため、日除け用シート１を被遮光物の上に設置することで、日除け用シートが被遮光物に対して落とす影により、太陽光を大幅に遮り、被遮光物の温度上昇を抑制するか、又は太陽光に曝露されていた被遮光物を冷却することができる。他方、日除け用シート１を使用時の立体構造にした状態で側面視した日除け用シート１では適度な開口１４ａ，１５ａ，３４ａ，３５ａがあいているため、開口１４ａ，１５ａ，３４ａ，３５ａが空気を効果的に流通させ、シート１０の表面の温度上昇を抑制し、また、シート１０の下部空間の熱溜まりを防止する。これにより、遮光性能および通風性能を同時に発揮し、シート１０でありながら、太陽光を遮光しつつ風も通すことで涼感を与える作用を発揮する。 FIG. 3 is a plan view of the awning sheet 1 of FIG. The awning sheet 1 of the embodiment of the present invention is formed by a portion of the sheet 10 in which the cuts 14, 15, 34, 35 of the sheet 10 are opened and the cuts 14, 15, 34, 35 are defined when viewed in a plan view. Except for the openings 14a, 15a, 34a, 35a, most of which is occupied by the area of the sheet 10. The area occupied by the sheet 10 with respect to the outer area of the awning sheet 1 viewed in a plan view with the awning sheet 1 in a three-dimensional structure at the time of use, in other words, the openings 14a and 15a with respect to the outer area of the awning sheet 1 viewed in a plan view. The area excluding, 34a and 35a is 80% or more, preferably 90% or more. Therefore, by installing the awning sheet 1 on the light-shielded object, the shadow cast by the awning sheet on the light-shielded object significantly blocks sunlight and suppresses the temperature rise of the light-shielded object. Or, it is possible to cool a light-shielded object that has been exposed to sunlight. On the other hand, since the awning sheet 1 has appropriate openings 14a, 15a, 34a, 35a when viewed from the side in a state where the awning sheet 1 has a three-dimensional structure at the time of use, the openings 14a, 15a, 34a, 35a are air. Is effectively distributed, the temperature rise on the surface of the sheet 10 is suppressed, and heat accumulation in the lower space of the sheet 10 is prevented. As a result, it exhibits light-shielding performance and ventilation performance at the same time, and even though it is a sheet 10, it exerts an effect of giving a cool feeling by allowing wind to pass through while blocking sunlight.

本発明の実施形態の日除け用シート１は、屋内、屋外のいずれで用いることもできる。本発明の実施形態の日除け用シート１により被覆される被遮光物は、光を遮りたい物であれば特に限定されない。典型的には植物が挙げられ、植物としては、蔬菜（野菜とも言う）、果樹、花卉等が挙げられる。野菜、果樹、花卉等を本発明の実施形態の日除け用シート１を用いて飼育すると、土の表面や日除け用シート１の下にある植物体が日陰となって、通気性を確保しつつ涼しく保たれるため、強い日差しの下でも良好な生育を促すことができる。 The awning sheet 1 according to the embodiment of the present invention can be used indoors or outdoors. The light-shielding object covered with the sunshade sheet 1 of the embodiment of the present invention is not particularly limited as long as it is an object that wants to block light. Typical examples include plants, and examples of plants include oligoculture (also referred to as vegetables), fruit trees, and flowers. When vegetables, fruit trees, flowers, etc. are bred using the awning sheet 1 of the embodiment of the present invention, the soil surface and the plants under the awning sheet 1 become shaded and cool while ensuring breathability. Because it is maintained, it can promote good growth even in strong sunlight.

図４は、植物の地上部の一部を本発明の実施形態の日除け用シート１のＶ字の切れ込みに通過させて太陽に露出するようにした状態で、土を覆って図１に示す日除け用シート１を配置した例を示す。このように、日除け用シート１の切れ込みにより通気性を確保しつつ、太陽に露出させる部分以外の植物の部分や土の表面を遮光し、地面の温度上昇を防ぐことができる。 FIG. 4 shows the awning shown in FIG. 1 in a state where a part of the above-ground part of the plant is passed through the V-shaped notch of the awning sheet 1 of the embodiment of the present invention to be exposed to the sun, and the soil is covered. An example in which the sheet 1 is arranged is shown. In this way, it is possible to prevent the temperature of the ground from rising by shielding the plant portion and the soil surface other than the portion exposed to the sun while ensuring the air permeability by the notch of the sunshade sheet 1.

図５は、写真の側方に延びる２つの畝を、植物体の地上部の全部又は一部が露出するように公知の遮光シートで覆い、２つの畝間と、２つの畝の各々の片側の側面とのそれぞれに本発明の実施形態の日除け用シート１を配置した状態を畝の上から撮影した写真である。このように、本発明の実施形態の日除け用シート１は、畝の真上だけでなく、２つの畝の間や、畝の側面にも配置することができる。 In FIG. 5, the two lateral ridges in the photograph are covered with a known light-shielding sheet so that all or part of the above-ground part of the plant is exposed, between the two ridges and on one side of each of the two ridges. It is a photograph taken from the top of the ridge in the state where the awning sheet 1 of the embodiment of the present invention is arranged on each side surface. As described above, the awning sheet 1 according to the embodiment of the present invention can be arranged not only directly above the ridges but also between the two ridges and on the side surfaces of the ridges.

図６は、複数並べて配置した育苗ポットの上に日除け用シートを配置した例を示す。育苗ポットには植物の種子、幼苗、その他育苗ポットで生育可能な任意の植物が植えられている。このように、日除け用シート１のＶ字の切れ込みにより通気性を確保しつつ、太陽に露出させる部分以外の植物の部分や土の表面を遮光し、地面の温度上昇を防ぐことができる。育苗ポットを日除け用シート１で覆うことで乾燥を防ぐこともできるため、育苗ポットにて栽培されている植物の生育が促される。 FIG. 6 shows an example in which a sunshade sheet is arranged on a plurality of seedling raising pots arranged side by side. The seedling pot is planted with plant seeds, seedlings, and any other plant that can grow in the nursery pot. In this way, it is possible to prevent the temperature of the ground from rising by shielding the plant parts and the soil surface other than the parts exposed to the sun while ensuring the air permeability by the V-shaped notch of the sunshade sheet 1. Since it is possible to prevent the seedling raising pot from drying out by covering it with the sunshade sheet 1, the growth of the plants cultivated in the seedling raising pot is promoted.
