【考案の詳細な説明】
本考案は農作物の温室、ハウス栽培に使用され

フイルムに関するものである。[Detailed Description of the Invention] The present invention relates to an agricultural covering film used for growing crops in greenhouses and greenhouses, and more specifically to an agricultural film suitable for horizontal curtains in greenhouses and greenhouses.
従来より、農業用被覆材として軟質ポリ塩化ビ

多重被覆の一方法であるが、カーテンの内張りは

である反面、ハウス内、外面の温度差によつて、
ハウス外張り被覆材内面に凝縮した水滴が内張り

上に水溜りを形成し、ひいては水の重みによりい
わゆる“金魚鉢現象”と呼ばれるカーテンフイル
ムの水溜り袋が発生する。 Traditionally, films based on soft polyvinyl chloride, ethylene-vinyl acetate copolymer, polyethylene, etc. have been commonly used as agricultural covering materials.
Particularly in recent years, there has been a trend toward multiple coatings in order to prevent the temperature inside greenhouses from dropping. Curtains inside greenhouses and greenhouses are also a method of multiple coating, but while the inner lining of curtains is useful for keeping the temperature high inside the greenhouse or greenhouse, it also protects the inside and outside of the greenhouse. Due to temperature difference,
Water droplets condensed on the inner surface of the house exterior sheathing fall onto the lining curtain, forming a puddle on the lining curtain, and the weight of the water eventually causes a water puddle on the curtain film, a so-called "fishbowl phenomenon." do.
このため、カーテンの開閉作業に困難をきたし

くの問題が発生し、なかでも水平張りカーテンの
場合は特に深刻な問題になつていた。 This makes it difficult to open and close the curtains, impairs the durability of the film, and sometimes the water bag acts as a lens that focuses sunlight, negatively impacting the growth of crops. A number of problems arose, particularly with horizontal curtains.
また、朝方あるいは夕方のハウス内外の急激な
温度変化により霧やモヤがカーテン近傍で発生

発生の原因となつていた。 In addition, rapid temperature changes inside and outside the greenhouse in the morning or evening cause fog and mist to form near the curtains, causing unnecessarily humid conditions for crops and causing disease.
本考案者らは、これらの状況をかんがみ鋭意検

“金魚鉢現象”が起らないということを見い出し、
本考案に到達した。 The inventors of the present invention have conducted extensive studies in consideration of these circumstances, and have found that a perforated film, in which a synthetic resin film has at least one hole with a diameter of 4 mm or less per square meter of area, can be used as a curtain film in greenhouses. We discovered that it is extremely effective in keeping the temperature warm, and that the "fishbowl phenomenon" does not occur.
We have arrived at this idea.
すなわち、ハウス外張りフイルム内面に凝縮し
た水滴は、内張りカーテンフイルム上に落下し、
徐々にフイルム上面に水のたまりを形成するが、
透孔部のところでは水の界面張力により、すぐさ

形成する。さらに水のたまりがある程度増加し、
もはや水の界面張力によつて水滴の重さが支えき

を防ぐ結果、ハウス内の保温効果を著しく向上さ
せる。 In other words, water droplets condensed on the inner surface of the house exterior film fall onto the interior curtain film,
A puddle of water gradually forms on the top of the film, but
Due to the interfacial tension of the water at the through-holes, it immediately turns into water droplets and forms a water film without flowing down from the holes. In addition, water accumulation increases to some extent,
When the weight of the water droplets becomes too much to support due to the interfacial tension of the water, they will flow down through the holes, and this situation will be repeated, causing curtains with perforated films to become ``fishbowls''. Not only does this phenomenon not occur, but the formation of a water film in the holes prevents radiation from passing through from above the ground at night, significantly improving the heat retention effect inside the greenhouse.
また、本考案の有孔フイルムをカーテン等の農

増大するなど著しい効果を発揮する。 In addition, when the perforated film of the present invention is used as an agricultural covering material such as a curtain, it is possible to prevent the generation of fog and mist, improve flowability, and keep the humidity within the perforated film covering low. It has an anti-mildew effect, can prevent the occurrence of diseases, and has remarkable effects such as increasing crop yields.
本考案に使用される合成樹脂フイルムは、農業
用ハウス被覆材として用いることのできるもので
あればいずれでも適用が可能であり特に限定され

酸化防止剤、耐候剤、可塑剤などのほか、流滴性
付与として一般に用いられる界面活性剤を含有さ
せることが可能であり、さらに保温性効果を増大
させる目的で無機フイラー、金属粉、顔料などを
必要に応じて添加することによりカーテン資材と
して理想的なフイルムが得られる。 The synthetic resin film used in the present invention is not particularly limited, and any film that can be used as an agricultural house covering material can be used. In addition, in addition to antioxidants, weathering agents, plasticizers, etc., the synthetic resin film can also contain surfactants, which are commonly used to impart droplet properties. By adding inorganic fillers, metal powder, pigments, etc. as necessary, a film ideal for curtain materials can be obtained.
本考案の特徴とする直径４mm以下の透孔を設け
る位置は特に指定はなく、規則正しいピツチであ
つてもよいし、ランダムな位置であつてもよい。
透孔の直径は、適量の水により水膜を形成させる
ため直径４mm以下が好ましいが、フイルムの強
度、水の流下サイクルから直径１〜４mmがより好
ましい。 The positions where the through holes with a diameter of 4 mm or less, which are a feature of the present invention, are provided are not particularly specified, and may be at regular pitches or at random positions.
The diameter of the pores is preferably 4 mm or less in order to form a water film with an appropriate amount of water, but is more preferably 1 to 4 mm in view of the strength of the film and the water flow cycle.
また透孔の数は面積１m2当り１個以上であれば
フイルムの強度を考慮しつついくらでも可能であ
る。 Further, the number of through holes can be any number as long as it is one or more per square meter of area, taking into consideration the strength of the film.
本考案による有孔フイルムの製造方法は特に限
定されるものではなく、機械パンチ法、溶融穿孔
法などいづれの方法で製造されても差しつかえな
い。 The method of manufacturing the perforated film according to the present invention is not particularly limited, and any method such as a mechanical punching method or a melt perforation method may be used.
