本発明の実施の形態の設備について以下説明する。 Equipment according to embodiments of the present invention will be described below.

図２に示すように、培養液を入れる水槽１に植物の株ｋを定植する定植用パネル２を設ける。 As shown in FIG. 2, a planting panel 2 for planting a plant strain k is provided in a tank 1 containing a culture solution.

定植用パネル２には、植物の株ｋを定植する定植用の孔２ａを多数設けている。すなわち、一つの株ｋを一つの定植用の孔２ａに定植する構成である。 The planting panel 2 is provided with a large number of planting holes 2a for planting the plant strain k. That is, one stock k is planted in one planting hole 2a.

定植用パネル２の上方には、植物の株ｋの上部が貫通する案内孔３ａを多数設ける遮光パネル３を設ける。定植用パネル２と遮光パネル３は発泡スチロール等の樹脂性が望ましい。定植用パネル２は水槽１側に支持され、遮光パネル３はステー等の昇降用支持具４に支持される構成とする。なお、定植用パネル２と遮光用パネル３の載置位置は上下方向に同じ位置に設ける。これにより、定植用の孔２ａと案内孔３ａとが対向する位置に位置決めさせることができる。 Above the fixed planting panel 2, a light shielding panel 3 having a large number of guide holes 3a through which the upper part of the plant stock k penetrates is provided. The planting panel 2 and the light shielding panel 3 are preferably made of resin such as polystyrene foam. The planting panel 2 is supported on the water tank 1 side, and the light shielding panel 3 is supported by a lifting support 4 such as a stay. The planting panel 2 and the light shielding panel 3 are placed at the same position in the vertical direction. As a result, the fixed planting hole 2a and the guide hole 3a can be positioned at positions facing each other.

図１に示すように、昇降用支持具４及び遮光パネル３は、水槽１の上部より上方に向かって延びる昇降装置５によって上下方向に昇降可能に構成する。昇降装置５は例えばギアラックやネジ式のシャフト等で構成するのが望ましい。昇降装置５は架台３０の支柱に取り付ける構成でも良いし、架台の支柱を兼ねてもよい。 As shown in FIG. 1, the lifting support 4 and the light shielding panel 3 are configured to be vertically movable by a lifting device 5 extending upward from the top of the water tank 1 . The lifting device 5 is desirably composed of, for example, a gear rack, a screw-type shaft, or the like. The lifting device 5 may be configured to be attached to the support of the pedestal 30, or may also serve as the support of the pedestal.

昇降用支持具４は手動用ハンドル１２や、昇降装置５の駆動モータＭの駆動により上下動する構成である。駆動モータＭの配置は適宜行うことができる。 The lifting support 4 is configured to move up and down by driving the manual handle 12 or the driving motor M of the lifting device 5 . Arrangement of the drive motor M can be performed appropriately.

水槽１の周囲には水槽１を覆う暗幕１８で覆う。暗幕１８は昇降用支持具４側に支持される構成である。また、遮光パネル３の上方には天井部６を設ける。 The circumference of the water tank 1 is covered with a blackout curtain 18 for covering the water tank 1.例文帳に追加The blackout curtain 18 is configured to be supported on the lifting support 4 side. A ceiling portion 6 is provided above the light shielding panel 3 .

定植用パネル２と遮光パネル３は所定間隔で離間し、定植用の孔２ａと案内孔３ａを上下方向に対向する位置に設ける。栽培の開始時には、植物の株ｋの下部を定植用の孔２ａに挿入し、株ｋの根を水槽１内の培養液に浸されるようにする。そして、株ｋの上部を案内孔３ａを通過させて、株ｋの上端部を遮光パネル３より上方に突出させる。すなわち、株ｋの上端部以外は、遮光パネル３により外光に晒されないように構成している。 The planting panel 2 and the light shielding panel 3 are spaced apart at a predetermined distance, and the planting hole 2a and the guide hole 3a are provided at positions opposed to each other in the vertical direction. At the start of cultivation, the lower part of the plant strain k is inserted into the hole 2a for fixed planting so that the roots of the plant strain k are immersed in the culture solution in the water tank 1.例文帳に追加Then, the upper part of the stock k is passed through the guide hole 3 a to project the upper end of the stock k upward from the light shielding panel 3 . That is, the shading panel 3 prevents exposure to outside light except for the upper end of the stock k.

図２に示すように、定植用パネル２と遮光パネル３の外形は同型に形成しており、相違点は、定植用パネル２の孔の径より遮光パネル３の径を小さく形成している。これにより、遮光パネル３を株ｋの上部が通過しながら外光が遮光パネル４を通過しにくくすることができながら、株ｋを定植用パネルの孔２ａに定植しやすくすることができる。また、定植用パネル２上には株ｋの周囲を覆う覆い筒体７を載置する。そして、栽培開始時には覆い筒体７の上部を遮光パネル３の下面に当接させることで、株ｋの上部が遮光パネル３の案内孔３ａに案内しやすいようにしている。また、栽培開始時に覆い筒体７の上部に遮光パネル３が当接する構成にすることで、定植用パネル２と遮光パネル３の距離を一定にすることができる。また、株ｋを案内孔３ａに挿入しやすくすることができる。覆い筒体７は定植用パネル２及び遮光用パネル３に対して特に固定しない構成にすることで、植物の収穫時には、覆い筒体７を簡単に定植用パネル２から取り外すことができる。 As shown in FIG. 2, the planting panel 2 and the light shielding panel 3 have the same outer shape, and the difference is that the diameter of the light shielding panel 3 is smaller than the hole diameter of the planting panel 2 . As a result, while the upper part of the stock k passes through the light shielding panel 3, it is possible to make it difficult for outside light to pass through the light shielding panel 4, while facilitating the planting of the stock k in the hole 2a of the planting panel. Also, on the planting panel 2, a cover cylinder 7 is placed to cover the perimeter of the stock k. At the start of cultivation, the upper part of the cover cylinder 7 is brought into contact with the lower surface of the light shielding panel 3, so that the upper part of the stock k can be easily guided to the guide hole 3a of the light shielding panel 3. In addition, the distance between the fixed planting panel 2 and the light shielding panel 3 can be kept constant by adopting a configuration in which the light shielding panel 3 contacts the upper portion of the cover cylinder 7 at the start of cultivation. In addition, the stock k can be easily inserted into the guide hole 3a. By configuring the cover tube 7 not to be particularly fixed to the planting panel 2 and the light shielding panel 3, the cover tube 7 can be easily removed from the planting panel 2 when the plants are harvested.

図１１に示すように、遮光パネル３の案内孔３ａは上端部から下広がりのテーパー状に形成してもよい。これにより、株ｋの上部を遮光パネル３の案内孔３ａに案内しやすくすることができる。この場合には、案内孔３ａの下部の径を定植用パネルの孔２ａより大きくしてもよい。この場合にも、案内孔３ａの上端部が定植用パネルの孔２ａの上端部より小さく形成することが遮光能力上望ましい。 As shown in FIG. 11, the guide hole 3a of the light shielding panel 3 may be formed in a tapered shape expanding downward from the upper end. As a result, the upper part of the stock k can be easily guided to the guide hole 3a of the light shielding panel 3. As shown in FIG. In this case, the diameter of the lower part of the guide hole 3a may be made larger than the hole 2a of the planting panel. Also in this case, it is desirable from the standpoint of light shielding ability that the upper end of the guide hole 3a is smaller than the upper end of the hole 2a of the planting panel.

図４には、定植用パネル２の水槽１への取り付け構成が示されている。すなわち、水槽１には、定植用パネル２を載置するためのフランジ部１ａが側面方向に延びるよう形成されており、定植用パネル２下面をフランジ部１ａに載置する構成であり、フランジ部１ａに設ける位置決め部１ｂで位置決めされる。これにより、定植用パネル２を簡単な構成で設置したり取り外したりすることができる。また、配置位置を一定にすることができる。 FIG. 4 shows a configuration for attaching the planting panel 2 to the water tank 1. As shown in FIG. That is, the water tank 1 is formed with a flange portion 1a for mounting the planting panel 2 so as to extend in the lateral direction, and the lower surface of the planting panel 2 is mounted on the flange portion 1a. It is positioned by a positioning portion 1b provided on 1a. Accordingly, the planting panel 2 can be installed and removed with a simple configuration. Also, the arrangement position can be made constant.

遮光パネル３の上面には高反射フィルムを張り付け、下面には銀イオンを塗布するようにしてもよい。これにより、遮光パネル３より上方に突出した株ｋの上端部に照射する外光の量を増やして株ｋの促進を図ると共に、暗幕１８に覆われ、かつ、水槽１側に面する下面の汚れを低減や防腐作用を促進させることができる。 A highly reflective film may be attached to the upper surface of the light shielding panel 3, and silver ions may be applied to the lower surface. As a result, the amount of outside light irradiated to the upper end portion of the stock k protruding upward from the light shielding panel 3 is increased to promote the growth of the stock k. It can reduce dirt and promote antiseptic action.

栽培時には、株ｋの生長に合わせて昇降装置５を作動させることにより、昇降用支持具４が上昇すると共に、暗幕１８も上昇することで、絶えず株ｋの上端部分のみ外光に晒すようにしている。暗幕１８と遮光パネル３により、株ｋの途中部は外光に晒されないため、株ｋの途中部の色が白色となる。 At the time of cultivation, by operating the lifting device 5 in accordance with the growth of the stock k, the lifting support 4 is lifted and the blackout curtain 18 is also lifted, so that only the upper end portion of the stock k is constantly exposed to the outside light. ing. Since the blackout curtain 18 and the light shielding panel 3 prevent the middle part of the stock k from being exposed to the outside light, the middle part of the stock k becomes white.

株ｋが所定の長さまで生長したら、オペレータは遮光パネル３を取り外し、覆い筒体７を取り外し、定植用パネル２から植物の株ｋを引き抜いて収穫する。 When the stock k grows to a predetermined length, the operator removes the light shielding panel 3, removes the cover cylinder 7, pulls out the plant stock k from the planting panel 2, and harvests it.

あるいは、定植用パネル２毎水槽１より取り外して収穫してもよい。 Alternatively, the planting panel 2 may be removed from the water tank 1 and harvested.

本実施の形態は白ネギ等のいわゆる軟白野菜を栽培するのに適している。 This embodiment is suitable for cultivating so-called soft white vegetables such as white onions.

次に、天井部６に栽培用の人工光用照射部材１３を取り付けた場合について図６、図７に基づいて説明する。 Next, the case where the artificial light irradiation member 13 for cultivation is attached to the ceiling portion 6 will be described with reference to FIGS. 6 and 7. FIG.

図６に示すように、天井部６に人工光用照射部材１３を取り付け、天井部６を昇降装置５で昇降自在に構成している。天井部６は、昇降用支持具４の上昇と共に上昇させる。すなわち、昇降用支持具４の上面と人工光照射部材１３との距離を略一定とするよう調節する。これにより、株ｋの上端部への人工光の照射が一定となり、安定した栽培を行うことが可能である。 As shown in FIG. 6 , the artificial light irradiation member 13 is attached to the ceiling portion 6 , and the ceiling portion 6 is configured to be vertically movable by the lifting device 5 . The ceiling part 6 is raised together with the lifting support 4 . That is, the distance between the upper surface of the lifting support 4 and the artificial light irradiation member 13 is adjusted to be substantially constant. As a result, the irradiation of the artificial light to the upper end of the strain k becomes constant, and stable cultivation can be performed.

昇降用支持具４の上昇及び天井部６の上昇は手動でも調節可能であるが、制御で上昇させることも可能である。例えば図１０に示すように昇降用支持具４の上面に光電センサ１４を配置する。光電センサ１４は遮光パネル３より上方に突出する株ｋの上端部の長さを検出できる構成としており、図６に示すように光電センサ１４による株ｋの上端部の生長の検出を制御部Ｓで判定する。そして、制御部Ｓから昇降装置５に出力することで、昇降用支持具４を所定距離上昇させる。光電センサ１４も昇降用支持具４と共に上昇可能に構成することで、遮光パネル３から突出する株ｋの長さを良好に検出できる。光電センサ１４はいわゆるエリアセンサでも可能である。 The elevation of the lifting support 4 and the elevation of the ceiling portion 6 can be adjusted manually, but it is also possible to raise them by control. For example, as shown in FIG. 10, the photoelectric sensor 14 is arranged on the upper surface of the lifting support 4 . The photoelectric sensor 14 is configured to be able to detect the length of the upper end of the stock k that protrudes upward from the light shielding panel 3. As shown in FIG. to judge. Then, by outputting from the controller S to the lifting device 5, the lifting support 4 is lifted by a predetermined distance. By configuring the photoelectric sensor 14 so that it can be lifted together with the lifting support 4, the length of the plant k protruding from the light shielding panel 3 can be detected satisfactorily. The photoelectric sensor 14 can also be a so-called area sensor.

人工光用照射部材１３は調光器Ｔにより、光量の調節が可能である。光量は栽培開始から期間毎に変更制御するように設定する構成としてもよい。望ましくは、株ｋの生長に伴って光量を多くする。 The light amount of the artificial light irradiation member 13 can be adjusted by a dimmer T. FIG. The amount of light may be set so as to be changed and controlled for each period from the start of cultivation. Desirably, the amount of light is increased as the strain k grows.

人工光用照射部材１３を備える天井部６は図１に示すように固定式にして調光器Ｔにより株ｋの生長に応じて光量を変更する構成にしてもよい。 As shown in FIG. 1, the ceiling part 6 provided with the artificial light irradiation member 13 may be of a fixed type, and may be configured to change the amount of light according to the growth of the plant k by means of a dimmer T.

あるいは、人工光用照射部材が無く、太陽光による栽培でも良い。 Alternatively, there is no irradiation member for artificial light, and cultivation by sunlight may be used.

図３及び図１２には、定植用パネル２から植物を収穫する際に、定植用パネル２の下方から伸長する根を除去し易くするための構成である。すなわち、水槽１に株ｋの根が通過するための孔１７ａを多数形成するメタル部材１７を載置し、メタル部材１７に定植用パネル２を載置する。植物の収穫時には定植用パネル２を持ち上げてメタル部材１７と離間させ、当該離間した部分にカッター等の根の切断装置Ｄを挿入することで、株ｋの根を切断する。これにより、定植用パネル２を持ち上げ易くすることができ、定植用パネル２から植物を引き抜きやすくすることができる。 FIGS. 3 and 12 show configurations for facilitating removal of roots extending from below the planting panel 2 when harvesting plants from the planting panel 2 . That is, a metal member 17 having a large number of holes 17a for the roots of the stock k to pass through is placed in the water tank 1, and the planting panel 2 is placed on the metal member 17. As shown in FIG. When the plant is harvested, the planting panel 2 is lifted to separate it from the metal member 17, and a root cutting device D such as a cutter is inserted into the separated portion to cut the root of the stock k. Thereby, the planting panel 2 can be easily lifted, and the plant can be easily pulled out from the planting panel 2. - 特許庁

図５には、水槽１に培養液の供給及び排出を行う構成が示されている。水槽１を架台３０に載置し、架台３０の下方のスペースに培養液を収容する培養液収容タンク８を設置してもよい。培養液収容タンク８には水槽１へ培養液を供給する供給ポンプ１８を設け、培養液供給ライン１９を水槽１へ接続することで、培養液を水槽１へ供給する構成である。
また、水槽１には、培養液を排出する培養液排出ライン２０と培養液の排出を行うための排出弁２１を設け、培養液排出ライン２０は培養液収容タンク８と接続することで、排出した培養液を再度、利用できる構成である。なお、詳細は記載しないが培養液収容タンク８内に水や各種肥料を投入して培養液を生成できる構成としている。 FIG. 5 shows a configuration for supplying and discharging the culture medium to and from the water tank 1. As shown in FIG. The water tank 1 may be mounted on a frame 30, and the culture solution storage tank 8 for containing the culture solution may be installed in the space below the frame 30. FIG. The culture solution storage tank 8 is provided with a supply pump 18 for supplying the culture solution to the water tank 1 , and a culture solution supply line 19 is connected to the water tank 1 to supply the culture solution to the water tank 1 .
Further, the water tank 1 is provided with a culture solution discharge line 20 for discharging the culture solution and a discharge valve 21 for discharging the culture solution. It is a configuration in which the culture solution obtained after the culture can be used again. Although not described in detail, the tank 8 is configured so that water and various fertilizers can be put into the tank 8 to generate a culture solution.

培養液収容タンク８内には培養液のＥＣ値を検出するＥＣセンサ及び培養液のｐｈ（ペーハ）を検出するｐＨセンサを設けてもよい。これにより、培養液の濃度，酸度管理が可能となる。また、リン酸イオンセンサを設けてリン酸イオンを管理し，欠乏症を予防できるようにしてもよい。特に、ネギ類はリンが欠乏することによる葉先の白変が生じることによる商品価値の低下を防止することができる。また、ＮＨ４+イオンセンサを設け、アンモニア態窒素（ＮＨ４+）を所定量供給することで、葉折れを防止することができる。 An EC sensor for detecting the EC value of the culture medium and a pH sensor for detecting the ph (pH) of the culture medium may be provided in the culture medium storage tank 8 . This makes it possible to control the concentration and acidity of the culture solution. Also, a phosphate ion sensor may be provided to manage phosphate ions and prevent deficiency. In particular, welsh onions can be prevented from deteriorating in commercial value due to white discoloration of leaf tips due to phosphorus deficiency. Further, by providing an NH4+ ion sensor and supplying a predetermined amount of ammonium nitrogen (NH4+), leaf folding can be prevented.

また、水温計及び培養液の加温部材を設け、培養液の水温を所定範囲内の温度に維持することも可能である。 It is also possible to provide a water thermometer and a heating member for the culture solution to maintain the water temperature of the culture solution within a predetermined range.

また、酸素濃度計とエアーポンプを加えた構成により、酸素濃度により撹拌用のエアーポンプをON－OFF制御し、溶存酸素濃度管理による生育促進を図ることができる。そして、エアーポンプの吐出口をタンク内水位よりも高く配管することで、撹拌時に水とエアを同時に落とし込むことで培養液内の酸素を確保することができる。エアーポンプは常時駆動でも良い。 In addition, by adding an oxygen concentration meter and an air pump, the air pump for stirring can be ON-OFF controlled according to the oxygen concentration, and growth can be promoted by managing the dissolved oxygen concentration. By setting the discharge port of the air pump higher than the water level in the tank, water and air are dropped at the same time during stirring, thereby ensuring oxygen in the culture solution. The air pump may be constantly driven.
