Description

本発明は、ぶどうを鳥獣から保護する鳥獣害防止用保護傘に関する。 The present invention relates to a protective umbrella for preventing damage to birds and beasts that protects grapes from birds and beasts.

近年、カラス、ハクビシン、アライグマ等の増加により、これらの害鳥獣がぶどう畑に侵入し農作物を荒らすことが問題になっている。これらの獣鳥害を防止するために、様々な対策が講じられている。 In recent years, due to the increase in crows, palm civets, raccoons, etc., it has become a problem that these harmful birds and beasts invade vineyards and damage crops. Various measures have been taken to prevent these beast and bird damage.

従来、ぶどうの露地栽培において、鳥獣害防止対策として、特開2005-116号公報(特許文献2)に示すような、防護ネットで覆うか、或いは、特開2011-167102号公報(特許文献1)に示すような、電気柵などが用いられていた。 Conventionally, in open-field cultivation of grapes, as a measure to prevent damage to birds and beasts, the grapes are covered with a protective net as shown in JP-A-2005-116 (Patent Document 2), or JP-A-2011-167102 (Patent Document 1). ), An electric fence or the like was used.

特開2011-167102号公報Japanese Unexamined Patent Publication No. 2011-167102 特開2005-116号公報Japanese Unexamined Patent Publication No. 2005-116 特開2016-15960号公報Japanese Unexamined Patent Publication No. 2016-15960

しかし、従来の特許文献2に示すような、ネットをかけるやり方では、設置の大変さや、少しの隙間から侵入することがあり、また、特許文献1に示すような電気柵を設置する場合、小規模園地では設置や維持のコストや労力がかかってしまう問題があり、さらに、ネットや電気柵を設置できない畑もあり、十分な対策ができない問題があった。 However, the conventional method of connecting a net as shown in Patent Document 2 may be difficult to install and may invade through a small gap, and when an electric fence as shown in Patent Document 1 is installed, it is small. In large-scale gardens, there was a problem that installation and maintenance costs and labor were required, and there were also fields where nets and electric fences could not be installed, so there was a problem that sufficient measures could not be taken.

本発明の課題は、ぶどう全体を覆うような大きく丈夫な傘をかけることにより、個々のぶどうを保護できるぶどうの鳥獣害防止用保護傘を提供することにある。 An object of the present invention is to provide a protective umbrella for preventing damage to individual grapes by wearing a large and durable umbrella that covers the entire grape.

本発明によるぶどうの鳥獣害防止用保護傘は、ぶどうの果実に合成樹脂フィルムを被せて鳥獣害から保護するための保護傘であって、前記合成樹脂フィルムは、中央の枝挿入孔から端縁に至る切り込みが形成され、対向する端縁との寸法を40cmから80cmの範囲に選定するとともに、板厚を0.18mmから0.4mmまでの範囲に選定したことを要旨としている。 The protective umbrella for preventing damage to grapes according to the present invention is a protective umbrella for covering grape fruits with a synthetic resin film to protect them from damage to birds and animals, and the synthetic resin film extends from a central branch insertion hole to an edge. The gist is that the notch is formed and the dimension with the opposite edge is selected in the range of 40 cm to 80 cm, and the plate thickness is selected in the range of 0.18 mm to 0.4 mm.

また、前記合成樹脂フィルムは、前記枝挿入孔にぶどうの枝が挿入され、前記切り込みを互いに重ね合わせて前記ぶどうを包囲する傘状の保護傘を形成し、この保護傘の前記枝挿入孔から下端に至る寸法を前記ぶどうの果実の全長よりも長くしている。 Further, in the synthetic resin film, a branch of grape is inserted into the branch insertion hole, and the cuts are overlapped with each other to form an umbrella-shaped protective umbrella surrounding the grape, and the protective umbrella is formed from the branch insertion hole to the lower end. All dimensions are longer than the total length of the grape fruit.

本発明によるぶどうの鳥獣害防止用保護傘によれば、合成樹脂フィルムの対向する端縁との寸法を40cmから80cmの範囲に選定しているので、巨峰、シャインマスカット、或いはナガノパープル等の房の長さが大きい葡萄であっても保護傘を全体に包囲することができる。これにより、ハクビシン等の害獣がぶどうに近接することができない。また、野鳥も保護傘の下端に止まった場合にも近接することができないことから、ぶどうを鳥獣害から防止することができる。さらに、合成樹脂フィルムの板厚を0.18mmから0.4mmまでの範囲に選定しているので、合成樹脂フィルムの硬度と厚さにより、害獣や野鳥が爪を保護傘に引っ掛けようとしても阻止できるので、鳥獣害から防止することができる。さらに、中央の枝挿入孔から端縁に至る切り込みが形成されているので、ぶどうを簡単な作業により包囲することができる。 According to the protective umbrella for preventing damage to grapes and animals according to the present invention, the dimension of the synthetic resin film with the opposite edge is selected in the range of 40 cm to 80 cm. Even long grapes can be surrounded by a protective umbrella. As a result, harmful animals such as masked palm civet cannot approach the grapes. In addition, since wild birds cannot approach even if they stop at the lower end of the protective umbrella, grapes can be prevented from being damaged by birds and beasts. Furthermore, since the thickness of the synthetic resin film is selected in the range of 0.18 mm to 0.4 mm, the hardness and thickness of the synthetic resin film prevent vermin and wild birds from catching their nails on the protective umbrella. Because it can be done, it can be prevented from damage to birds and beasts. In addition, a notch from the central branch insertion hole to the edge is formed so that the grapes can be surrounded by a simple operation.

また、合成樹脂フィルムにより形成された傘状の保護傘は、この保護傘の枝挿入孔から下端に至る寸法をぶどうの果実の全長よりも長くしているので、害獣がぶどうに近接することを阻止することができる。 In addition, the umbrella-shaped protective umbrella made of synthetic resin film has a dimension from the branch insertion hole to the lower end of the protective umbrella longer than the total length of the grape fruit, preventing vermin from approaching the grape. can do.

本発明によるぶどうの鳥獣害防止用保護傘は、ぶどうの果実に合成樹脂フィルムを被せて鳥獣害から保護するための保護傘であって、前記合成樹脂フィルムは、中央の枝挿入孔から端縁に至る切り込みが形成され、対向する端縁との寸法を40cmから80cmの範囲に選定するとともに、板厚を0.18mmから0.4mmまでの範囲に選定したことを要旨としている。 The protective umbrella for preventing damage to grapes according to the present invention is a protective umbrella for covering grape fruits with a synthetic resin film to protect them from damage to birds and animals, and the synthetic resin film extends from a central branch insertion hole to an edge. The gist is that the notch is formed and the dimension with the opposite edge is selected in the range of 40 cm to 80 cm, and the plate thickness is selected in the range of 0.18 mm to 0.4 mm.

以下、ぶどうの鳥獣害防止用保護傘の実施例について、図1及び図2により説明する。図1は、鳥獣害防止用の保護傘1を示している。この保護傘1は、透明または半透明のプラスチック素材からなる合成樹脂フィルムであり、サイズは、長辺の寸法を40cmから80cmの範囲に選定している。また、厚さは0.18mmから0.4mmまでの範囲に選定している。また、材質としては、PP(ポリプロピレン)高透明PP(ポリプロピレン)再生PP(ポリプロピレン再生高透明PP(ポリプロピレン)再生PETが好適である。その他、延伸ナイロン、延伸ポリ乳酸、または延伸ポリスチレン、エチレン-ビニルアルコール共重合体の材質のプラスチック素材も使用することができる。さらに、合成樹脂フィルムは、透明または半透明または乳白色にすることが望ましい。 Hereinafter, examples of a protective umbrella for preventing damage to grapes and animals will be described with reference to FIGS. 1 and 2. FIG. 1 shows a protective umbrella 1 for preventing wildlife damage. The protective umbrella 1 is a synthetic resin film made of a transparent or translucent plastic material, and the size of the long side is selected in the range of 40 cm to 80 cm. The thickness is selected in the range of 0.18 mm to 0.4 mm. Further, as the material, PP (polypropylene) highly transparent PP (polypropylene) recycled PP (polypropylene recycled highly transparent PP (polypropylene) recycled PET is suitable. In addition, stretched nylon, stretched polylactic acid, or stretched polystyrene, ethylene-vinyl. A plastic material as the material of the alcohol copolymer can also be used. Further, it is desirable that the synthetic resin film is transparent, translucent or milky white.

保護傘1は、図1に示すように正方形に形成され、中央には、枝挿入孔2が形成されている。この枝挿入孔2の内径は、ぶどうの枝の太さとほぼ同じに設定している。さらに、枝挿入孔2から保護傘1の端縁に至るまでの間に、切り込み3が形成されている。なお、保護傘1の形状は、長方形、円形、楕円形、或いは多角形のいずれでも良い。 The protective umbrella 1 is formed in a square shape as shown in FIG. 1, and a branch insertion hole 2 is formed in the center thereof. The inner diameter of the branch insertion hole 2 is set to be substantially the same as the thickness of the grape branch. Further, a notch 3 is formed between the branch insertion hole 2 and the end edge of the protective umbrella 1. The shape of the protective umbrella 1 may be rectangular, circular, elliptical, or polygonal.

以上のように構成された保護傘1は、図2に示すように、ぶどう4の周囲に包囲される。この保護傘1によりぶどう4を包囲する時期は、ぶどう4の果実の肥大が始まり、袋掛け作業が終わる開花30日を過ぎた頃から、ぶどう4の着色が始まる満開後50日までの間に設置することが望ましい。保護傘1が特に必要な時期は、ぶどう4が甘く熟す頃になると、ハクビシンなどの獣が好んで摂取し、ぶどう4の収穫時期に食害に合う可能性が高くなることから、食害に合う前に未然に防止するためである。 As shown in FIG. 2, the protective umbrella 1 configured as described above is surrounded by the grape 4. The time to surround the grape 4 with this protective umbrella 1 is from about 30 days after the flowering when the fruit of the grape 4 starts to grow and the bagging work ends to 50 days after the grape 4 starts to be colored. It is desirable to do. When the grape 4 is sweet and ripe, the beasts such as masked palm civet prefer to ingest it when the protective umbrella 1 is particularly needed, and it is more likely that the grape 4 will be damaged during the harvest. This is to prevent it from happening.

保護傘1を図2に示すようにぶどう4に包囲するには、まず、図1に示す保護傘1の切り込み3を広げながらぶどう4の枝4aが枝挿入孔2に達するまで挿入する。その後、ぶどう4に巻き付けるように切り込み3の左右に引きながら重ね合わせ、この状態で止め具5により数ヶ所を固定する。なお、ぶどう4には、害虫による食害などから守る、雨水などによって感染する病気から守る、防除による果粉(ブルーム)の溶脱を防ぐ、日焼けを防止するなどの目的で、予め袋6が掛けられている。従って、保護傘1は、袋6の周囲を包囲するように設置される。 In order to surround the protective umbrella 1 with the grape 4 as shown in FIG. 2, first, the branch 4a of the grape 4 is inserted until the branch 4a of the grape 4 reaches the branch insertion hole 2 while widening the notch 3 of the protective umbrella 1 shown in FIG. After that, they are overlapped while being pulled to the left and right of the notch 3 so as to be wrapped around the grape 4, and in this state, several places are fixed by the stopper 5. The grape 4 is preliminarily hung with a bag 6 for the purpose of protecting it from feeding damage caused by pests, protecting it from diseases transmitted by rainwater, preventing leaching of fruit powder (bloom) by controlling it, and preventing sunburn. There is. Therefore, the protective umbrella 1 is installed so as to surround the circumference of the bag 6.

ぶどう1は、多くの種類が存在しているが、保護傘1の合成樹脂フィルムの大きさを、対向する端縁との寸法を40cmから80cmの範囲にすることにより、巨峰、シャインマスカット、或いはナガノパープル等の房の長さが大きいぶどう4の場合にも、図2に示すように、ぶどう4の下端UL1よりも、保護傘1の下端UL2が下方になり、ぶどう4の全体が完全に包囲される。保護傘1の合成樹脂フィルムの大きさを40cmから80cmの範囲とするのは、上述したぶどう1の他、多種なぶどう4の房が包囲するための長さによって選定される。また、厚さを0.18mmから0.4mmまでの範囲に選定しているのは、ぶどう4に巻き付けた後、切り込み3の左右を引きながら重ね合わせるときの作業性が良好であり、しかも、害獣7或いは野鳥の爪等によって破れることがない必要最小限の厚さとしている。 There are many types of grape 1, but by setting the size of the synthetic resin film of the protective umbrella 1 to the range of 40 cm to 80 cm with the opposite edge, Kyoho, Shine Muscat, or Nagano Even in the case of grape 4 having a large bunch of purple or the like, as shown in FIG. 2, the lower end UL2 of the protective umbrella 1 is below the lower end UL1 of the grape 4, and the entire grape 4 is completely surrounded. Grape. The size of the synthetic resin film of the protective umbrella 1 is selected in the range of 40 cm to 80 cm according to the length for surrounding the various bunches of grapes 4 in addition to the above-mentioned grape 1. In addition, the thickness is selected in the range of 0.18 mm to 0.4 mm because the workability is good when the grapes are wound around the grape 4 and then overlapped while pulling the left and right sides of the notch 3. The thickness is set to the minimum necessary so that it will not be torn by the vermin 7 or the claws of wild birds.

このように、保護傘1によって、ぶどう4を包囲することにより、例えば、ハクビシン等の害獣7、或いは野鳥がぶどうに近接しても、ぶどう4に接触することができない。また、保護傘1の合成樹脂フィルムの板厚が0.18mmから0.4mmと厚くなっていて、しかも、害獣7や野鳥が爪を引っ掛けても破れることがないので、ぶどう4を鳥獣害から防止される。 In this way, by surrounding the grape 4 with the protective umbrella 1, for example, even if a vermin 7 such as a palm civet or a wild bird approaches the grape, it cannot come into contact with the grape 4. In addition, the thickness of the synthetic resin film of the protective umbrella 1 is as thick as 0.18 mm to 0.4 mm, and even if the vermin 7 or wild birds catch their claws, they will not be torn. Be prevented.

以上、本発明を実施例に基づき具体的に説明したが、本発明は上記実施例に限定されるものではなく、その要旨を逸脱しない範囲で種々変形可能であることは言うまでもない。例えば、上述した実施例において、重ね合わせた保護傘を止める止め具として、粘着テープを用いても良い。 Although the present invention has been specifically described above based on the examples, it is needless to say that the present invention is not limited to the above examples and can be variously modified without departing from the gist thereof. For example, in the above-described embodiment, an adhesive tape may be used as a stopper for stopping the overlapping protective umbrellas.
