Description

本発明は、植物を栽培するための装置及び方法にかかり、特に、植物を水耕栽培するための装置及び方法に関する。 The present invention relates to an apparatus and method for cultivating a plant, and more particularly to an apparatus and method for hydroponically cultivating a plant.

農作物等の植物を栽培する方法として、土を使わずに水と液体肥料(養液)で植物を栽培する水耕栽培といった方法がある。水耕栽培では、土を使わないことから、土壌管理が不要であり、養液を管理することで計画的な栽培が可能となる。そして、水耕栽培では、例えば、特許文献1に記載されているように、養液を収容する養液槽と、養液槽に浮かべられ植物を保持する植物保持具と、が必要となる。 As a method of cultivating plants such as agricultural products, there is a method of hydroponics in which plants are cultivated with water and liquid fertilizer (nutrient solution) without using soil. Since hydroponics does not use soil, soil management is not required, and systematic cultivation is possible by managing the nutrient solution. Then, in hydroponics, for example, as described in Patent Document 1, a nutrient solution tank for accommodating the nutrient solution and a plant holder for holding the plant floating in the nutrient solution tank are required.

[構成]
本実施形態における水耕栽培装置は、図1に示すように水田Gで用いられる。つまり、本実施形態における水耕栽培装置は、水田Gに張られた水を用いて水耕栽培を行うための装置である。但し、本発明における水耕栽培装置は、必ずしも水田Gで用いられることに限定されず、プールやため池など、水が張られた領域であれば利用可能である。
[Constitution]
The hydroponic cultivation apparatus in this embodiment is used in paddy field G as shown in FIG. That is, the hydroponic cultivation device in the present embodiment is an device for performing hydroponic cultivation using the water filled in the paddy field G. However, the hydroponic cultivation apparatus in the present invention is not necessarily limited to being used in the paddy field G, and can be used in any water-filled area such as a pool or a pond.

図1に示すように、水耕栽培装置は、水田Gの水面W上に広げられるシート材1と、当該シート材1をロール状に巻き取るシート巻取り装置10と、シート材1に連結された紐体2を折り返すための折り返し装置20と、を備える。そして、シート巻取り装置10は、水田Gの水面Wを囲う所定の縁(一方の縁)に配置され、当該シート巻取り装置10が配置される所定の縁とは水面Wを挟んで対岸に位置する他の縁(他方の縁)には、折り返し装置20が配置される。つまり、水田Gの水面Wを囲う相互に対向する一方と他方の縁に、それぞれシート巻取り装置10と折り返し装置20とが配置される。なお、水田Gの水面Wを囲う縁とは、例えば、畦であるが、水面Wを囲う領域であればいかなる場所であってもよい。 As shown in FIG. 1, the hydroponic cultivation device is connected to the sheet material 1 spread on the water surface W of the paddy field G, the sheet winding device 10 for winding the sheet material 1 in a roll shape, and the sheet material 1. A folding device 20 for folding back the string body 2 is provided. Then, the sheet winding device 10 is arranged on a predetermined edge (one edge) surrounding the water surface W of the paddy field G, and is on the opposite bank with the water surface W sandwiched from the predetermined edge on which the sheet winding device 10 is arranged. A folding device 20 is arranged at the other edge (the other edge) where it is located. That is, the sheet winding device 10 and the folding device 20 are arranged on one and the other edges of the paddy field G, which surround the water surface W and face each other. The edge surrounding the water surface W of the paddy field G is, for example, a ridge, but it may be any place as long as it is an area surrounding the water surface W.

ここで、シート材1及びシート巻取り装置10の構成について、図3乃至図5を参照して説明する。まず、シート材1は、所定の幅と長さを有する帯状体からなる部材である。例えば、シート材1は、竹や葦などを編んで構成された簾にて構成されている。つまり、シート材1は、幅方向に沿って竹や葦などの複数の棒状体が並行に配置され、これら複数の棒状体が長さ方向に沿って連結されて構成されている。このため、シート材1を構成する竹や葦などの複数の棒状体間には隙間が形成されており、シート材1自体の表面と裏面とを貫通する貫通部が形成されていることとなる。また、シート材1は、竹や葦などを編んで構成されていることから、その浮力にて水面Wに浮かべられるよう構成されている。 Here, the configurations of the sheet material 1 and the sheet winding device 10 will be described with reference to FIGS. 3 to 5. First, the sheet material 1 is a member made of a strip-shaped body having a predetermined width and length. For example, the sheet material 1 is made of bamboo blinds made by weaving bamboo, reeds, and the like. That is, the sheet material 1 is configured by arranging a plurality of rod-shaped bodies such as bamboo and reeds in parallel along the width direction, and connecting the plurality of rod-shaped bodies along the length direction. Therefore, a gap is formed between a plurality of rod-shaped bodies such as bamboo and reeds constituting the sheet material 1, and a penetrating portion penetrating the front surface and the back surface of the sheet material 1 itself is formed. .. Further, since the sheet material 1 is formed by knitting bamboo, reeds, or the like, it is configured to float on the water surface W by its buoyancy.

また、シート材1は、裏面側を水面W側に向けて当該水面Wに浮かべることができ、かかる状態で表面側に栽培対象物Tを配置することで、当該栽培対象物Tは貫通部から水田G内の水を得ることができる。つまり、栽培対象物Tは、シート材1の貫通部から水田G内に根を伸ばすことで、水を得ることができる。なお、栽培対象物Tは、例えば、リーフレタス、ホウレンソウ、ミツバ、ミズナ、などの野菜類であってもよく、いかなる植物であってもよい。 Further, the sheet material 1 can be floated on the water surface W with the back surface side facing the water surface W side, and by arranging the cultivation object T on the front surface side in such a state, the cultivation object T can be transmitted from the penetrating portion. Water in paddy field G can be obtained. That is, water can be obtained from the cultivated object T by extending the roots into the paddy field G from the penetrating portion of the sheet material 1. The cultivated object T may be, for example, vegetables such as leaf lettuce, spinach, Japanese honeywort, and Mizuna, or any plant.

また、シート材1は、上述したように幅方向に沿って複数の棒状体が並行に配置されている構成であるため、長さ方向に沿ってロール状に巻き取られた状態とすることが可能である。このとき、シート材1は、シート巻取り装置10にて巻き取られてロール状に形成されるが、そのときの様子を図3乃至図4に示す。なお、図4では、シート材1である簾を構成する竹や葦などの棒状体を図示しているが、図3では、ロール状のシート材1の全体構成がわかりやすいよう、簾を構成する竹や葦などの棒状体を図示せずに簡略的に示している。また、図5においても、シート材1を簡略的に示している。 Further, since the sheet material 1 has a configuration in which a plurality of rod-shaped bodies are arranged in parallel along the width direction as described above, the sheet material 1 may be wound in a roll shape along the length direction. It is possible. At this time, the sheet material 1 is wound by the sheet winding device 10 to be formed in a roll shape, and the state at that time is shown in FIGS. 3 to 4. Note that FIG. 4 shows a rod-shaped body such as bamboo or reed that constitutes the bamboo blind, which is the sheet material 1, but FIG. 3 shows the bamboo blind so that the overall structure of the roll-shaped sheet material 1 can be easily understood. Rod-shaped bodies such as bamboo and reeds are shown briefly without being shown. Further, also in FIG. 5, the sheet material 1 is simply shown.

そして、シート巻取り装置10は、本実施形態では、シート材1を巻き取る際に中心軸となる軸体を備えており、かかる軸体が地面から所定の高さ位置で回転可能なよう支持される構造となっている。これにより、シート巻取り装置10は、軸体にシート材1を巻き付けた状態で当該軸体を回転させることで、シート材1をロール状に巻き取ることができる。なお、シート巻取り装置10は、軸体を回転させるハンドルを備えていてもよく、かかるハンドルを回転させることでシート材1をロール状に巻き取ってもよい。但し、シート巻取り装置10は、いかなる方法でシート材1をロール状に巻き取るよう構成されていてもよく、例えば、手動ではなくモータなどのアクチュエータを用いて回転して、シート材1を巻き取るよう構成されていてもよい。 In the present embodiment, the sheet winding device 10 includes a shaft body that serves as a central axis when the sheet material 1 is wound, and supports the shaft body so that it can rotate at a predetermined height position from the ground. It has a structure to be used. As a result, the sheet winding device 10 can wind the sheet material 1 in a roll shape by rotating the shaft body in a state where the sheet material 1 is wound around the shaft body. The sheet winding device 10 may include a handle for rotating the shaft body, and the sheet material 1 may be wound in a roll shape by rotating the handle. However, the sheet winding device 10 may be configured to wind the sheet material 1 in a roll shape by any method. For example, the sheet material 1 is wound by rotating the sheet material 1 using an actuator such as a motor instead of manually. It may be configured to take.

また、図3に示すように、上記シート材1の長さ方向の一端、つまり、ロール状となっているときの最外周に位置する一端には、紐体2が連結されている。具体的に、紐体2は、シート材1の一端において、所定の間隔をあけて2本連結されており、かかる2本の紐体2はその先で1本に集約されている。そして、紐体2は、全体の長さが、水田Gの水面Wを挟んだ縁間を1往復する長さ以上に形成されている。つまり、紐体2は、水田Gの水面Wを挟んで相互に対岸に配置されたシート巻取り装置10と折り返し装置20との間の距離の2倍以上の長さに形成されている。 Further, as shown in FIG. 3, the string body 2 is connected to one end of the sheet material 1 in the length direction, that is, one end located at the outermost circumference when the sheet material 1 is in a roll shape. Specifically, two string bodies 2 are connected at one end of the sheet material 1 at a predetermined interval, and the two string bodies 2 are aggregated into one at the end. The total length of the string body 2 is formed to be longer than the length of one round trip between the edges of the paddy field G sandwiching the water surface W. That is, the string body 2 is formed to have a length more than twice the distance between the sheet winding device 10 and the folding device 20 arranged on opposite banks of the water surface W of the paddy field G.

また、上述したシート巻取り装置10とは水田Gの水面Wを挟んで対岸に配置された折り返し装置20は、例えば、滑車を備えて構成されている。折り返し装置20は、水田Gの一方の縁に位置するシート巻取り装置10にてロール状に巻き取られたシート材1の端部から他方の縁側に延びる紐体2を、滑車に巻き付けて再度一方の縁側に折り返させ、紐体2の先端をシート巻取り装置10の位置まで延ばして配置させる。これにより、紐体2の先端が、シート巻取り装置10の位置で一方の縁側に引っ張られることで、折り返し装置20の滑車にて円滑に紐体2の引っ張り方向が反転し、シート材1の端部を他方の端部側に引っ張ることができる。なお、折り返し装置20は、必ずしも滑車を備えていることに限定されず、いかなる構成であってもよい。 Further, the folding device 20 arranged on the opposite bank of the paddy field G with the water surface W sandwiched from the sheet winding device 10 described above is configured to include, for example, a pulley. The folding device 20 winds the string body 2 extending from the end of the sheet material 1 wound in a roll shape by the sheet winding device 10 located at one edge of the paddy field G to the other edge side around the pulley again. It is folded back to one edge side, and the tip of the string body 2 is extended to the position of the sheet winding device 10 and arranged. As a result, the tip of the string body 2 is pulled toward one edge side at the position of the sheet winding device 10, so that the pulling direction of the string body 2 is smoothly reversed by the pulley of the folding device 20, and the sheet material 1 The end can be pulled towards the other end. The folding device 20 is not necessarily limited to having a pulley, and may have any configuration.

First, the procedure for planting the cultivated object T in the paddy field G will be described mainly with reference to the flowchart of FIG.

まず、作業者Uは、シート材1をシート巻取り装置10で巻き取ってロール状にし、水田Gの一方の縁に配置する。また、作業者Uは、シート巻取り装置10を配置した水田Gの一方の縁の対岸に位置する他方の縁に、折り返し装置20は配置する(図6のステップS1)。そして、作業者Uは、水田Gの一方の縁に位置するシート巻取り装置10にロール状に巻き付けられているシート材1の一端に連結された紐体2を、対岸である水田Gの他方の縁に位置する折り返し装置20の滑車に巻き付けて一方の縁側に折り返し、さらに紐体2の先端側を一方の縁に位置するシート巻取り装置10の場所に配置する(図6のステップS2)。これにより、作業者Uは、図1に示すように、水田Gの一方の縁側のシート巻取り装置10の位置にて、紐体20を把持した状態となる。 First, the worker U winds the sheet material 1 with the sheet winding device 10 to form a roll, and arranges the sheet material 1 on one edge of the paddy field G. Further, the worker U arranges the folding device 20 on the other edge located on the opposite bank of one edge of the paddy field G in which the sheet winding device 10 is arranged (step S1 in FIG. 6). Then, the worker U attaches the string body 2 connected to one end of the sheet material 1 wound in a roll shape to the sheet winding device 10 located at one edge of the paddy field G to the other side of the paddy field G on the opposite bank. Wrap around the pulley of the folding device 20 located at the edge of the string, fold it back to one edge side, and further arrange the tip end side of the string body 2 at the location of the sheet winding device 10 located at the one edge (step S2 in FIG. 6). .. As a result, as shown in FIG. 1, the worker U is in a state of gripping the string body 20 at the position of the sheet winding device 10 on one edge side of the paddy field G.

続いて、作業者Uは、図1の矢印Y1に示すように、紐体2を一方の縁側に引っ張る。このとき、わずかな距離だけ紐体2を引っ張ることで、図3に示すように、ロール状のシート材1の先端が他方の縁側に引っ張られて、当該シート材1がロール状から引き出される(図6のステップS3)。これにより、シート材1が、シート巻取り装置10の上部にて面を形成するよう広がる。そして、作業者Uは、図3に示すように、シート巻取り装置10の上部にて広げられたシート材1の表面に、1つ又は複数の栽培対象物Tを配置する(図6のステップS4)。なお、このときに配置する栽培対象物Tは、水耕栽培されるリーフレタス、ホウレンソウ、ミツバ、ミズナ、などの野菜類といった植物の苗であるが、いかなる植物であってもよい。また、苗などの栽培対象物Tは、土がついたままの状態であってもよく、いかなる状態のものであってもよい。 Subsequently, the worker U pulls the string body 2 toward one edge side as shown by the arrow Y1 in FIG. At this time, by pulling the string body 2 by a slight distance, as shown in FIG. 3, the tip of the roll-shaped sheet material 1 is pulled toward the other edge side, and the sheet material 1 is pulled out from the roll-shaped sheet material 1 ( Step S3 in FIG. 6). As a result, the sheet material 1 spreads so as to form a surface at the upper part of the sheet winding device 10. Then, as shown in FIG. 3, the worker U arranges one or a plurality of cultivation objects T on the surface of the sheet material 1 spread at the upper part of the sheet winding device 10 (step of FIG. 6). S4). The cultivated object T arranged at this time is a seedling of a plant such as leaf lettuce, spinach, Japanese honeywort, Japanese honeywort, etc. that are hydroponically cultivated, but any plant may be used. Further, the cultivated object T such as seedlings may be in a state where the soil is still attached, or may be in any state.

その後、作業者Uは、上述したように、紐体2をわずかな距離だけ引っ張る作業と(図6のステップS3)、シート巻取り装置10の上部に広げられたシート材1の表面に栽培対象物Tを配置する作業と(図6のステップS4)、を繰り返し行う。つまり、作業者Uは、紐体2を少しずつ引っ張りながら、ロール状からシート材1を少しずつ引き出し、新たに引き出されたシート材1のシート巻取り装置10の上部に広がる領域に、新たな栽培対象物Tを配置することを繰り返す。これにより、図5に示すように、シート材1の表面に栽培対象物Tが配置された状態で、水田Gの水面W上に徐々に広げられることとなる。 After that, as described above, the worker U pulls the string body 2 by a slight distance (step S3 in FIG. 6), and the worker U cultivates the surface of the sheet material 1 spread on the upper part of the sheet winding device 10. The work of arranging the object T and (step S4 of FIG. 6) are repeated. That is, the worker U pulls out the sheet material 1 from the roll shape little by little while pulling the string body 2 little by little, and a new area spreads over the sheet winding device 10 of the newly pulled out sheet material 1. The arrangement of the cultivation target T is repeated. As a result, as shown in FIG. 5, the cultivated object T is arranged on the surface of the sheet material 1 and is gradually spread on the water surface W of the paddy field G.

そして、作業者Uは、図1の矢印Y2に示すように、シート材1がシート巻取り装置10が位置する水田Gの一方の縁側から対岸の他方の縁側まで引き出されると(図6のステップS5でYes)、上述したシート材1の引き出しと栽培対象物Tを配置する作業を停止する。これにより、シート材1が、可能な限り水田Gの水面Wに広げられ、その表面に配置された栽培対象物Tの水耕栽培用の植え付けが完了する(図6のステップS6)。 Then, as shown by the arrow Y2 in FIG. 1, the worker U is pulled out from one edge side of the paddy field G where the sheet winding device 10 is located to the other edge side of the opposite bank (step in FIG. 6). Yes) in S5, the work of pulling out the sheet material 1 and arranging the cultivation target T described above is stopped. As a result, the sheet material 1 is spread as much as possible on the water surface W of the paddy field G, and the planting of the cultivation object T arranged on the surface thereof for hydroponics is completed (step S6 in FIG. 6).

上記のように植え付けられた栽培対象物Tは、シート材1が竹や葦などを編んで構成されていることから、図1に示すように水面Wに浮かべられた状態となる。また、栽培対象物Tは、シート材1の竹や葦などの隙間で形成された貫通部から、水田G内に根を伸ばして水を得ることができる。このようにして水耕栽培が実施される。 The cultivated object T planted as described above is in a state of being floated on the water surface W as shown in FIG. 1 because the sheet material 1 is formed by knitting bamboo, reeds, and the like. Further, the cultivated object T can obtain water by extending its roots into the paddy field G from the penetrating portion formed by the gap between the bamboo and the reeds of the sheet material 1. Hydroponics is carried out in this way.

次に、主に図7のフローチャートを参照して、水田で水耕栽培した栽培対象物Tを収穫する手順を説明する。作業者Uは、上述したように水田Gに植え付けられた栽培対象物Tである苗が栽培されて収穫可能な程度に成長した後に、以下の手順で収穫を行う。 Next, a procedure for harvesting the cultivated object T hydroponically cultivated in the paddy field will be described mainly with reference to the flowchart of FIG. 7. After the seedlings, which are the cultivation target T planted in the paddy field G, have been cultivated and grown to a harvestable extent as described above, the worker U harvests the seedlings according to the following procedure.

まず作業者Uは、シート巻取り装置10を操作して、水田Gの水面W上に広げられたシート材1を、長さ方向の他端側からロール状に巻き取る(図7のステップS11)。これにより、図2の矢印Y3に示すように、シート材1が水田Gの他方の縁側から一方の縁側に移動するよう巻き取られる。このとき、作業者Uは、シート巻取り装置10の上部付近に位置するシート材1の領域に水耕栽培された栽培対象物Tが位置するまで当該シート材1を巻き取り、かかる領域の栽培対象物Tを回収する(図7のステップS12)。 First, the operator U operates the sheet winding device 10 to wind the sheet material 1 spread on the water surface W of the paddy field G in a roll shape from the other end side in the length direction (step S11 in FIG. 7). ). As a result, as shown by the arrow Y3 in FIG. 2, the sheet material 1 is wound so as to move from the other edge side of the paddy field G to one edge side. At this time, the worker U winds the sheet material 1 until the hydroponically cultivated object T is located in the area of the sheet material 1 located near the upper part of the sheet winding device 10, and cultivates the area. The object T is collected (step S12 in FIG. 7).

その後、作業者Uは、シート材1を少しずつ巻き取る作業と(図7のステップS11)、シート巻取り装置10の上部に位置するシート材1の領域の栽培対象物Tを回収する作業と(図7のステップS12)、を繰り返し行う。つまり、作業者Uは、シート材1を少しずつ巻き取りながら、巻き取ったシート材1のシート巻取り装置10の上部に広がる領域に位置する栽培対象物Tを回収することを繰り返す。これにより、図2に示すように、水田Gの水面W上に広げられたシート材1の表面で栽培された栽培対象物Tが、次々と収穫されることとなる。 After that, the worker U winds up the sheet material 1 little by little (step S11 in FIG. 7), and collects the cultivated object T in the area of the sheet material 1 located at the upper part of the sheet winding device 10. (Step S12 in FIG. 7) is repeated. That is, the worker U repeats collecting the cultivated object T located in the region extending above the sheet winding device 10 of the wound sheet material 1 while winding the sheet material 1 little by little. As a result, as shown in FIG. 2, the cultivated object T cultivated on the surface of the sheet material 1 spread on the water surface W of the paddy field G is harvested one after another.

そして、作業者Uは、シート材1上のすべての栽培対象物Tを回収し、シート材1をすべてシート巻取り装置10に巻き取ると(図7のステップS13でYes)、栽培対象物Tの収穫が完了する(図7のステップS14)。 Then, when the worker U collects all the cultivated objects T on the sheet material 1 and winds all the sheet material 1 on the sheet winding device 10 (Yes in step S13 of FIG. 7), the cultivated object T Harvesting is completed (step S14 in FIG. 7).

以上のように、本実施形態における植物栽培装置及び植物栽培方法によると、作業者Uは、ロール状に巻き取られたシート材1の紐体2を引っ張りつつ、その場で栽培対象物Tをシート材1の表面に配置することで、栽培対象物Tが配置されたシート材1を水田Gの水面W上に広げることができる。また、作業者Uは、シート巻取り装置10にてシート材1を巻き取ることで、巻き取った場所に位置するシート材1上の栽培対象物Tを収穫することができる。このため、水田Gといった広い領域であっても、簡易な構成の装置を用いて栽培対象物Tの水耕栽培を行うことができ、装置にかかる費用の低減を図ることができる。また、植え付け作業や収穫作業をシート巻取り装置10の配置箇所で行うことができるため、広い範囲であっても一人で水耕栽培を行うことができ、作業効率の向上を図ることができる。 As described above, according to the plant cultivation apparatus and the plant cultivation method in the present embodiment, the worker U pulls the string body 2 of the sheet material 1 wound in a roll shape and grows the cultivation target T on the spot. By arranging it on the surface of the sheet material 1, the sheet material 1 on which the cultivated object T is arranged can be spread on the water surface W of the paddy field G. Further, the worker U can harvest the cultivated object T on the sheet material 1 located at the wound place by winding the sheet material 1 with the sheet winding device 10. Therefore, even in a wide area such as a paddy field G, the cultivation target T can be hydroponically cultivated by using an apparatus having a simple configuration, and the cost required for the apparatus can be reduced. Further, since the planting work and the harvesting work can be performed at the location where the sheet winding device 10 is arranged, hydroponics can be carried out by one person even in a wide range, and the work efficiency can be improved.

なお、上記では、シート材1の端部に連結された紐体2を、対岸の折り返し装置20を用いて折り返させて、シート巻取り装置10の配置箇所でシート材1の引き出し操作を行うこととしているが、紐体2は必ずしも対岸の折り返し装置20を用いて折り返すよう配置することに限定されない。例えば、シート巻取り装置10が配置された水田Gの一方の縁の対岸である他方の縁側に紐体2の先端を配置し、かかる紐体2を他方の縁側に位置する他の作業者が徐々に引っ張ってもよい。そして、水田Gの一方の縁側では、シート巻取り装置10の配置箇所にてもう一人の作業者Uが、少しずつ引き出されたシート材1の表面に栽培対象物Tを配置する作業を行ってもよい。これにより、栽培対象物Tが配置されたシート材1を、水田Gの一方の縁側から他方の縁側に向かって徐々に水面W上に広げることができる。 In the above, the string body 2 connected to the end of the sheet material 1 is folded back by using the folding device 20 on the opposite bank, and the sheet material 1 is pulled out at the location where the sheet winding device 10 is arranged. However, the string body 2 is not necessarily limited to being arranged so as to be folded back using the folding device 20 on the opposite bank. For example, another worker who arranges the tip of the string body 2 on the other edge side opposite to one edge of the paddy field G where the sheet winding device 10 is arranged and positions the string body 2 on the other edge side. You may pull it gradually. Then, on one edge side of the paddy field G, another worker U performs a work of arranging the cultivated object T on the surface of the sheet material 1 pulled out little by little at the arrangement location of the sheet winding device 10. May be good. As a result, the sheet material 1 on which the cultivated object T is arranged can be gradually spread on the water surface W from one edge side of the paddy field G toward the other edge side.

以上、上記実施形態等を参照して本願発明を説明したが、本願発明は、上述した実施形態に限定されるものではない。本願発明の構成や詳細には、本願発明の範囲内で当業者が理解しうる様々な変更をすることができる。 Although the invention of the present application has been described above with reference to the above-described embodiment and the like, the present invention is not limited to the above-described embodiment.
