Description
本発明は、果実栽培における二段式栽培棚に関する。
具体的には、果実栽培における二段式栽培棚において、多目的防災網のための棚の周囲柱が果実棚の周囲柱を兼ねる構造である果実栽培における二段式栽培棚に関する。
The present invention relates to a two-tiered cultivation rack for fruit cultivation.
Specifically, the present invention relates to a two-tiered cultivation shelf for fruit cultivation, in which the peripheral posts of the shelf for a multi-purpose disaster prevention net also serve as the peripheral posts of the fruit shelf.
果実栽培においては、防鳥、防虫、防風、雹害の防止のために、多目的防災網をかぶせることが行われている（特許文献１）。そのためには、果実棚、例えば、梨棚の場合には、通常の梨棚の上部に、さらに立設した支柱の間を鋼線などの線材で縦横に連結することで、多目的防災網を設置するための棚を設ける必要があり、果実栽培においては、二段式栽培棚を設置することが必要となっている。 In fruit cultivation, multipurpose disaster prevention netting is used to protect against birds, insects, wind, and hail damage (Patent Document 1). To achieve this, in the case of a fruit trellis, for example a pear trellis, a shelf must be provided on top of a normal pear trellis, with additional upright supports connected vertically and horizontally with wire such as steel wire, on which the multipurpose disaster prevention netting can be placed. In fruit cultivation, it is necessary to install a two-tier cultivation shelf.
従来、例えば、梨栽培の場合、梨棚と多目的防災網のための棚とを独立して設置しており、梨棚用の隅柱及び周囲柱を設置すると共に、多目的防災網のための棚用の隅柱及び周囲柱を設置していた。梨園の広さにもよるが、梨棚の設置のために、高さ２．５ｍ程度の４本の隅柱に加えて、５０本程度の周囲柱を用い、併せて、多目的防災網のための棚の設置のために、高さ４．５ｍ程度の４本の隅柱と３０本程度の周囲柱を用いることもあった。したがって、二段式栽培棚を設置するためには、資材が多く必要であり、設置に係る作業も負担となっていた。 Conventionally, for example, in the case of pear cultivation, the pear trellis and the shelves for the multi-purpose disaster prevention net were installed separately, and corner posts and surrounding posts for the pear trellis were installed, as well as corner posts and surrounding posts for the shelves for the multi-purpose disaster prevention net. Depending on the size of the pear orchard, in addition to four corner posts about 2.5 m high, about 50 surrounding posts were used to install the pear trellis, and at the same time, four corner posts about 4.5 m high and about 30 surrounding posts were used to install the shelves for the multi-purpose disaster prevention net. Therefore, a lot of materials were required to install two-tier cultivation shelves, and the work involved in installation was also burdensome.
本発明は、前記した従来技術の問題点を解決し、果実栽培における二段式栽培棚について、用いられる資材を削減し、簡便に設置できる二段式栽培棚を提供することを課題とする。 The present invention aims to solve the problems of the conventional technology described above and to provide a two-tiered cultivation shelf for fruit cultivation that reduces the amount of materials used and can be easily installed.
本発明者は、上記課題を解決するために検討した結果、隅柱については果実棚用の隅柱と多目的防災網のための棚用の隅柱とをそれぞれ４本ずつ設置すると共に、周囲柱については多目的防災網のための棚用の周囲柱を果実棚用の周囲柱と兼用することで、全体の保持強度を保ちつつ、果実棚用の周囲柱の本数を全体として削減できることを見出し、本発明を完成するに至った。 After studying ways to solve the above problems, the inventor discovered that by installing four corner columns for the fruit shelf and four corner columns for the shelf for the multipurpose disaster prevention net, and by using the peripheral columns for the shelf for the multipurpose disaster prevention net as the peripheral columns for the fruit shelf as well, it was possible to reduce the overall number of peripheral columns for the fruit shelf while maintaining the overall holding strength, and thus completed the present invention.
すなわち、本発明は、以下の事項により特定されるとおりのものである。
（１）果実栽培用の果実棚と多目的防災網のための棚とからなる二段式栽培棚において、多目的防災網のための棚用の周囲柱が、果実棚用の周囲柱を兼ねる構造であることを特徴とする、果実栽培用の二段式栽培棚。
（２）果実が梨である、（１）に記載の果実栽培用の二段式栽培棚。
（３）多目的防災網のための棚用の周囲柱の径が、果実棚用の周囲柱の径と同じかそれよりも大きいことを特徴とする、（１）又は（２）に記載の果実栽培用の二段式栽培棚。
That is, the present invention is specified by the following items.
(1) A two-tiered cultivation shelf for fruit cultivation comprising a fruit shelf for fruit cultivation and a shelf for a multi-purpose disaster prevention net, characterized in that the peripheral pillars for the shelf for the multi-purpose disaster prevention net are structured to also serve as the peripheral pillars for the fruit shelf.
(2) A two-tiered cultivation shelf for fruit cultivation according to (1), in which the fruit is a pear.
(3) A two-tiered cultivation shelf for fruit cultivation described in (1) or (2), characterized in that the diameter of the peripheral posts for the shelf for the multi-purpose disaster prevention net is the same as or larger than the diameter of the peripheral posts for the fruit shelf.
本発明によれば、果実栽培用の二段式栽培棚を設置する際に、栽培棚の保持強度を維持しながら、用いられる資材を削減することにより、簡便かつ安価に設置できる果実栽培用の二段式栽培棚を提供するものである。また、本発明によれば、周囲柱の角度を大きくとることができることから、支柱下のスペースが広く使え、栽培棚内での管理作業が容易となる。さらに、本発明によれば、多目的防災網のための棚の周囲柱が果実棚の周囲柱を兼ねることから、果実棚の高さの変更に際して、周囲柱の建替えなどの大幅な変更をすることなく、容易に変更できるものであり、作業者や経営者が変わり、作業環境が変わった場合であっても、フレキシブルな対応が可能である。 According to the present invention, a two-tiered cultivation shelf for fruit cultivation can be easily and inexpensively installed by reducing the materials used while maintaining the holding strength of the cultivation shelf. In addition, according to the present invention, the angle of the surrounding posts can be made large, making it possible to use the space under the posts widely and facilitating management work within the cultivation shelf. Furthermore, according to the present invention, the surrounding posts of the shelf for the multipurpose disaster prevention net also serve as the surrounding posts of the fruit shelf, so that the height of the fruit shelf can be easily changed without making major changes such as rebuilding the surrounding posts, and flexible response is possible even when the workers or manager change and the work environment changes.
本発明は、隅柱と周囲柱とを立設し、立設した柱間を線材で縦横に連結してなる果実栽培用二段式栽培棚において、隅柱については、果実棚用と多目的防災網のための棚用との隅柱をそれぞれ４本ずつ設置すると共に、周囲柱については、多目的防災網のための棚用の周囲柱を果実棚用の周囲柱と兼用して設置することを特徴とする果実栽培用二段式栽培棚である。以下に、その具体的態様について、梨栽培用二段式栽培棚を例として、具体的に説明するが、本発明は梨栽培用二段式栽培棚に限定されるものではない。 The present invention relates to a two-tiered cultivation shelf for fruit cultivation, which is constructed by erecting corner posts and peripheral posts and connecting the spaces between the erected posts vertically and horizontally with wire, and which is characterized in that the corner posts are provided with four corner posts each for the fruit shelf and for the shelf for a multipurpose disaster prevention net, and the peripheral posts for the shelf for the multipurpose disaster prevention net are also provided as peripheral posts for the fruit shelf. Specific embodiments of the two-tiered cultivation shelf for pear cultivation are explained below as an example, but the present invention is not limited to two-tiered cultivation shelves for pear cultivation.
二段式栽培棚は、隅柱、周囲柱及び線材で構成されており、隅柱と周囲柱は、それぞれ線材で連結されて均一な力で保持されている。柱の一端は地中に埋められているアンカーにより線材の張りと緊張を保たれている。 The two-tiered cultivation rack is made up of corner posts, surrounding posts, and wire. The corner posts and surrounding posts are connected with wire and held in place with uniform force. One end of the post is secured to an anchor buried in the ground, which keeps the wire taut and tensioned.
隅柱は、梨棚（下棚）用隅柱と多目的防災網のための棚（上棚）用隅柱とをそれぞれ４本ずつ設置する。梨棚（下棚）用隅柱と多目的防災網のための棚（上棚）用隅柱とを独立して設置することにより、棚全体の保持強度が向上する。梨棚（下棚）用隅柱と多目的防災網のための棚（上棚）用隅柱とは、同径の支柱を用いることもできるし、梨棚（下棚）用隅柱の径を多目的防災網のための棚（上棚）用隅柱の径よりも大きい支柱を用いることもできる。梨棚（下棚）用隅柱と多目的防災網のための棚（上棚）用隅柱とはクランプなどを用いて、連結させて設置することもできる。また、梨園の形状や広さにより、隅柱の数は４本に限られるものではない。 Four corner posts are installed each for the pear shelf (lower shelf) and the shelf (upper shelf) for the multipurpose disaster prevention net. By installing the corner posts for the pear shelf (lower shelf) and the shelf (upper shelf) for the multipurpose disaster prevention net separately, the holding strength of the entire shelf is improved. The corner posts for the pear shelf (lower shelf) and the shelf (upper shelf) for the multipurpose disaster prevention net can be of the same diameter, or the corner posts for the pear shelf (lower shelf) can be of a larger diameter than the corner posts for the shelf (upper shelf) for the multipurpose disaster prevention net. The corner posts for the pear shelf (lower shelf) and the shelf (upper shelf) for the multipurpose disaster prevention net can be connected and installed using clamps or the like. The number of corner posts is not limited to four, depending on the shape and size of the pear orchard.
周囲柱は、梨棚（下棚）用のための周囲柱と、梨棚（下棚）用と多目的防災網のための棚（上棚）用とを兼用する周囲柱とを用いることができる。すなわち、一部の周囲柱については、棚（上棚）用と多目的防災網のための棚（上棚）用とを兼ねることで、梨棚（下棚）用の周囲柱の本数を削減することができる。多目的防災網のための棚（上棚）用の周囲柱で梨棚（下棚）用の周囲柱を兼ねるものの数や割合は、棚の強度を保持できる範囲で適宜選択できるが、図１では、周囲柱の半分を多目的防災網のための棚用の周囲柱が兼用している態様を示している。梨棚（下棚）用と多目的防災網のための棚（上棚）用とを兼用する周囲柱の径は、梨棚（下棚）用のための周囲柱の径と同じでもよいが、梨棚と多目的防災網のための棚とを共に保持するために、梨棚（下棚）用の周囲柱の径よりも大きい径を用いることが好ましい。また、多目的防災網のための棚（上棚）用の周囲柱を用いることにより、周囲柱の設置角度が大きくなることから、梨棚（下棚）用の周囲柱を用いる場合に比べてスペースが広く使え、管理作業が容易になる。 The perimeter columns can be either for the pear shelf (lower shelf) or for both the pear shelf (lower shelf) and the shelf (upper shelf) for the multipurpose disaster prevention net. In other words, by using some of the perimeter columns for both the shelf (upper shelf) and the shelf (upper shelf) for the multipurpose disaster prevention net, the number of perimeter columns for the pear shelf (lower shelf) can be reduced. The number and ratio of perimeter columns for the shelf (upper shelf) for the multipurpose disaster prevention net that also serve as perimeter columns for the pear shelf (lower shelf) can be appropriately selected within a range that can maintain the strength of the shelf, but Figure 1 shows an embodiment in which half of the perimeter columns are also used as perimeter columns for the shelf for the multipurpose disaster prevention net. The diameter of the perimeter column that serves both the pear shelf (lower shelf) and the shelf (upper shelf) for the multipurpose disaster prevention net may be the same as the diameter of the perimeter column for the pear shelf (lower shelf), but it is preferable to use a diameter larger than the diameter of the perimeter column for the pear shelf (lower shelf) in order to hold both the pear shelf and the shelf for the multipurpose disaster prevention net. In addition, by using surrounding posts for the shelves (upper shelves) for the multi-purpose disaster prevention net, the installation angle of the surrounding posts is larger, allowing for more usable space and making maintenance easier than when surrounding posts are used for the pear shelves (lower shelves).
通常、梨棚（下棚）用に用いられる隅柱の長さは約２．５ｍであり、多目的防災網のための棚（上棚）用に用いられる隅柱の長さは約４．５ｍであり、周囲柱の長さは隅柱の長さよりも２０～５０ｃｍ程度短いことが好ましい。また、果実の種類、果樹園の状況により、長さは適宜選択することができる。 Normally, the length of the corner posts used for pear trellises (lower trellises) is about 2.5 m, and the length of the corner posts used for trellises (upper trellises) for multipurpose disaster prevention nets is about 4.5 m, and it is preferable that the length of the perimeter posts is about 20 to 50 cm shorter than the length of the corner posts. In addition, the length can be selected appropriately depending on the type of fruit and the conditions of the orchard.
梨棚（下棚）用と防災棚（上棚）用とに用いられる隅柱及び周囲柱の材質は、錆びたり、腐ったりすることがなければいずれの材質でも構わないが、ＪＩＳ規格鋼管が好適であり、また、柱の間をつなぐ線材についても特に制限はないが、日光の紫外線や農薬、外傷に対して耐久性があることから、鋼より線をポリエチレン被覆した線材が好適である。 The corner posts and surrounding posts used for the pear shelf (lower shelf) and the disaster prevention shelf (upper shelf) can be made of any material as long as it does not rust or rot, but JIS standard steel pipes are preferred. There are no particular restrictions on the wire connecting the posts, but polyethylene-coated steel strands are preferred because they are resistant to ultraviolet rays from sunlight, pesticides, and external damage.
本発明によれば、これまで、１０ａ当たりの梨園について、梨棚（下棚）用の周囲柱を４０本以上用いていたが、用いられる梨棚（下棚）の周囲柱の数を３分の１以下にしても、同程度の強度を維持することができた。 Until now, more than 40 peripheral posts for pear trellises (lower trellises) were used per 10a of pear orchards, but with this invention, the number of peripheral posts for pear trellises (lower trellises) used can be reduced to one-third or less and the same level of strength can be maintained.
以下に、図１を用いて、本発明の具体的な態様を説明するが、図１は本発明を何ら限定するものではない。 A specific embodiment of the present invention will be described below with reference to Figure 1, but Figure 1 does not limit the present invention in any way.
３０．０ｍ×３３．０ｍ四方の果樹園の４隅に、梨棚用の隅柱（１）と多目的防災網のための棚用の隅柱（２）を受石により設置した。梨棚用の隅柱（１）は８９．１ｍｍ径で、２７００ｍｍ長のサイズであり、多目的防災網のための棚用の隅柱（２）は７６．３ｍｍ径で、４５００ｍｍ長のサイズとした。隅柱の間に、等間隔に、８の周囲柱を受石により設置し、周囲柱は梨棚用のための周囲柱（３）と、梨棚（下棚）用と多目的防災網のための棚（上棚）用とを兼用する周囲柱（４）とを交互に設置した。梨棚用の周囲柱（３）は４８．６ｍｍ径で、２５００ｍｍ長のサイズであり、多目的防災網のための棚用の周囲柱（４）は６０．５ｍｍ径で、４０００ｍｍ長のサイズとした。したがって、本発明による周囲柱は、梨棚用の周囲柱（３）１６本と多目的防災網のための棚用の周囲柱（４）１６本との、計３２本を使用した。対向する周囲柱を線材で連結することで、梨棚及び多目的防災網のための棚を形成した。形成された梨棚及び多目的防災網のための棚の保持強度は、従来の棚と比べて、同程度であった。一方、従来の梨棚用の周囲柱と多目的防災網のための棚用の周囲柱とを分離して設置する方式では、梨棚用の周囲柱（３）３２本と多目的防災網のための棚用の周囲柱（４）１６本との、計４８本を使用するものであり、本発明により、梨棚用の周囲柱を１６本削減できることがわかった。 At the four corners of an orchard measuring 30.0 m x 33.0 m, corner posts (1) for a pear trellis and corner posts (2) for a shelf for a multipurpose disaster prevention net were installed with support stones. The corner posts (1) for the pear trellis were 89.1 mm in diameter and 2700 mm long, and the corner posts (2) for the shelf for the multipurpose disaster prevention net were 76.3 mm in diameter and 4500 mm long. Eight peripheral posts were installed at equal intervals between the corner posts with support stones, and the peripheral posts were alternately installed between peripheral posts (3) for the pear trellis and peripheral posts (4) that serve both the pear trellis (lower shelf) and the shelf (upper shelf) for the multipurpose disaster prevention net. The peripheral posts (3) for the pear trellis were 48.6 mm in diameter and 2500 mm long, and the peripheral posts (4) for the shelf for the multipurpose disaster prevention net were 60.5 mm in diameter and 4000 mm long. Therefore, a total of 32 perimeter columns were used according to the present invention, consisting of 16 perimeter columns (3) for the pear shelf and 16 perimeter columns (4) for the shelf for the multipurpose disaster prevention net. The shelves for the pear shelf and the multipurpose disaster prevention net were formed by connecting the opposing perimeter columns with wire. The holding strength of the formed shelves for the pear shelf and the multipurpose disaster prevention net was comparable to that of the conventional shelves. On the other hand, in the conventional method of separately installing the perimeter columns for the pear shelf and the perimeter columns for the shelf for the multipurpose disaster prevention net, a total of 48 columns were used, consisting of 32 perimeter columns (3) for the pear shelf and 16 perimeter columns (4) for the shelf for the multipurpose disaster prevention net. It was found that the present invention can reduce the number of perimeter columns for the pear shelf by 16.
以上の例からも、本発明によれば、果実棚用の周囲柱の数を削減することが可能となるだけでなく、周囲柱の設置に係るアンカー、受石などの部材も同様に削減できることがわかった。 From the above examples, it can be seen that the present invention not only makes it possible to reduce the number of surrounding pillars for a fruit shelf, but also reduces the number of anchors, receiving stones, and other components required for installing the surrounding pillars.
本発明によれば、果樹園における周囲柱の本数を削減することができ、コスト削減が図れると共に、果樹園のスペースを広く使うことが可能となることから、草刈りなどの管理作業が容易になり、さらに、周囲柱が上棚と下棚とを兼用することから、下棚の高さの変更を容易に行うことができ、経営者の変更に伴う改修のほかのみならず、多目的防災網を利用する技術に広く応用されることが期待されるものである。 This invention makes it possible to reduce the number of perimeter posts in an orchard, thus reducing costs and allowing for more space in the orchard, making maintenance tasks such as weeding easier. Furthermore, since the perimeter posts serve as both the upper and lower shelves, the height of the lower shelf can be easily changed. This invention is expected to be widely applied not only to renovations following a change in management, but also to technology that utilizes multipurpose disaster prevention nets.
