Description

イチゴ苗の生育システム及び生育方法Strawberry seedling growth system and growth method
　本発明は、イチゴ苗の生育システム及び生育方法に関する。 The present invention relates to a strawberry seedling growing system and a growing method.
　従来、親株から伸長するランナーに発生した子株を親株から切り離さずに生育するイチゴ苗の生育システムとしては、親株の栽培床を横長の親株栽培用栽培棚に設置し、その短手方向の片側に横長の子株栽培用栽培棚を平行配置して、これにランナーから発生した子株を定着させたポットを設置し、更に伸長するランナーに順次発生する新たな子株を別のポットに定着させて子株栽培用栽培棚に設置していくものが一般的に採用されている。 Conventionally, as a growth system for strawberry seedlings that grow offspring grown on runners that grow from the parent strain without being separated from the parent strain, the cultivation bed of the parent strain is installed on a cultivation shelf for cultivating the parent strain in a horizontal direction, and one side in the short direction is placed. Horizontally long cultivation racks for seedling cultivation are arranged in parallel, pots in which seedlings generated from runners are fixed are installed, and new seedlings that are successively generated on the growing runners are fixed in separate pots for seedling cultivation. It is generally adopted to be installed on the cultivation rack.
　上記生育システムでは、子株栽培用ポットに培地として土を入れたり、養液を供給したりするため、病原菌の増殖による培地汚染や害虫が発生して、病虫害になり易いという問題がある。更に培地があまり乾燥すると、発根してもうまく成長せず、水を十分与えても温度上昇により根腐れすることがある。 In the above-mentioned growth system, since soil is put into the seedling cultivation pot as a medium and a nutrient solution is supplied, there is a problem that the growth of pathogenic bacteria causes medium contamination and pests, which easily causes pests. Furthermore, if the medium is too dry, the roots will not grow well even if they take root, and even if they are sufficiently watered, the temperature will rise and the roots will rot.
　これに対し、親株栽培用栽培棚から透水性シートを垂れ下げて、親株から伸びるランナーをシート上に這わせる生育システムが提案されている（例えば特許文献１参照）。シートに対し定期的に散水してシートに接触する根から水分を吸わせるので、根が土に付かず、病虫害が抑制され、根腐れも防止される。しかし、根で吸収できる水分量が少なく、子株が生育しにくいという問題がある。また、親株から伸びるランナーは相当数あるため、子株栽培用栽培棚上で多数本のランナーが入り組んで絡み合う等、手入れがしにくいという問題もある。 On the other hand, a growing system has been proposed in which a water-permeable sheet is hung from a cultivation shelf for cultivating parent strains, and runners extending from the parent strain are laid on the sheet (see Patent Document 1, for example). Since the sheet is periodically watered to absorb water from the roots in contact with the sheet, the roots do not stick to the soil, disease and insect damage is suppressed, and root rot is prevented. However, there is a problem that the amount of water that can be absorbed by the roots is small and it is difficult for the seedlings to grow. In addition, since there are a considerable number of runners extending from the parent plant, there is also the problem of difficulty in maintenance, such as a large number of runners intertwining on the cultivation shelf for cultivating offspring.

　本発明の実施形態に係るイチゴの育苗システム１について図面を参照しながら説明する。育苗システム１は、水耕栽培用のイチゴの育苗に用いられ、図１に示すように、鉛直方向に３段（複数段）のプランター設置棚１１、１１、１１を有している。各プランター設置棚１１は、図１～３に示すように、概ね直方体形状で横長の親株栽培用プランター２と、親株栽培用プランター２の短手方向の両側方に略平行に配置される概ね直方体形状で横長の子株栽培用プランター３、３と、親株栽培用プランター２で栽培される親株Ｐから伸長するランナーＳＲに発生する子株Ｃを個別に定着させるウレタン培地４・・４を備える。各プランター設置棚１１の上方には、親株栽培用プランター２で栽培する親株Ｐ及び子株栽培用プランター３で栽培する子株Ｃに光を照射するＬＥＤ照明Ｌを備える。育苗システム１全体としては、親株栽培用プランター２及び子株栽培用プランター３と、照明Ｌと、が上下方向に交互に積層配置されることになる。 (Seedling system 1)
A strawberry seedling raising system 1 according to an embodiment of the present invention will be described with reference to the drawings. A seedling-raising system 1 is used for raising strawberry seedlings for hydroponic cultivation, and as shown in FIG. As shown in FIGS. 1 to 3, each planter installation shelf 11 includes a substantially rectangular parallelepiped planter 2 for cultivating a horizontally long parent strain, and a substantially rectangular parallelepiped that is arranged substantially parallel to both sides of the planter 2 for cultivating the parent strain in the short direction. It is provided with planters 3, 3 for cultivating offspring that are oblong in shape, and urethane media 4 for individually fixing offspring C generated on runners SR extending from the parental strain P cultivated in the planter 2 for cultivating parental strains. Above each planter installation shelf 11, an LED lighting L is provided for irradiating light to the parent strain P cultivated in the parent strain cultivation planter 2 and the offspring C cultivated in the offspring cultivation planter 3. In the seedling raising system 1 as a whole, the planters 2 for cultivating parent strains, the planters 3 for cultivating seedlings, and the lighting L are alternately stacked in the vertical direction.
（親株栽培用プランター２）
　親株栽培用プランター２は、図１～３で示すように、所定深さの養液Ｎが湛えられて、上面開口が蓋２１で閉鎖された養液槽である。蓋２１には、図２に示すように、長手方向に間隔をあけて親株Ｐを定植するための挿入孔２１aが設けられている。親株Ｐは、図３に示すように、周囲に巻いたスポンジ等の緩衝材２２を介して挿入孔２１ａに支持され、蓋２１の下方に露出する根Ｒｐが養液Ｎに浸たされる。また、図２に示すように、親株栽培用プランター２の長手方向の一端付近には、養液を供給する給液口２ａが設けられ、給液口２ａと反対側の他端付近には、養液を排出する排液口２ｂが設けられて、養液が給液口２ａから排液口２ｂへ向かって流れるように常時循環している。 (Parent strain cultivation planter 2)
As shown in FIGS. 1 to 3, the planter 2 for cultivating the parent strain is a nutrient solution tank filled with a nutrient solution N of a predetermined depth and having a top opening closed with a lid 21 . As shown in FIG. 2, the lid 21 is provided with insertion holes 21a for planting the parent strain P at intervals in the longitudinal direction. As shown in FIG. 3, the parent strain P is supported in the insertion hole 21a via a cushioning material 22 such as a sponge wrapped around it, and the root Rp exposed below the lid 21 is immersed in the nutrient solution N. In addition, as shown in FIG. 2, a liquid supply port 2a for supplying a nutrient solution is provided near one end in the longitudinal direction of the parent strain cultivation planter 2, and near the other end on the side opposite to the liquid supply port 2a, A drainage port 2b for discharging the nutrient solution is provided, and the nutrient solution is always circulated so as to flow from the supply port 2a toward the drainage port 2b.
　排液口２ｂから排出された養液は、育苗システム１の下部に設置した養液槽（不図示）に流下し、該養液槽のフィルターで異物を除去し、エアレーション装置（不図示）で溶存酸素を補った後、ポンプ（不図示）で給液口２ａへ送出される。排液口２ｂは、親株栽培用プランター２の底面から突出して上端が開口したオーバーフロー管で形成されており、根Ｒｐの略全体を浸せる養液深さを維持している。親株栽培用プランター２の養液Ｎは、蓋２１と、挿入孔２１ａに挿入した親株Ｐ及び緩衝材２２がプランター内部への光の進入を遮断することにより、青粉（藻類）の発生が抑制されている。なお、図１において、親株栽培用プランター２と下部に設置される養液槽やポンプ等とを繋ぐ配管等は省略されている。 The nutrient solution discharged from the drainage port 2b flows down into a nutrient solution tank (not shown) installed at the bottom of the seedling raising system 1, foreign matter is removed by a filter in the nutrient solution tank, and an aeration device (not shown) is used. After replenishing the dissolved oxygen, it is delivered to the liquid supply port 2a by a pump (not shown). The drain port 2b is formed by an overflow pipe protruding from the bottom surface of the planter 2 for cultivating the parent strain and having an open upper end, and maintains the depth of the nutrient solution so that substantially the entire root Rp can be immersed. In the nutrient solution N of the planter 2 for cultivating the parent strain, the cover 21, the parent strain P inserted into the insertion hole 21a, and the cushioning material 22 block the entry of light into the planter, thereby suppressing the generation of blue powder (algae). It is In addition, in FIG. 1, the piping etc. which connect the planter 2 for parent strain cultivation, and the nutrient solution tank, pump, etc. which are installed in the lower part are abbreviate|omitted.
（子株栽培用プランター３）
　子株栽培用プランター３、３は、図１～３で示すように、所定深さの水Ｗが湛えられ、上面が全面開口していて短手方向に大きな幅がある水槽で、親株栽培用プランター２の親株Ｐから伸びるランナーＳＲに順次発生する子株Ｃを水Ｗに浸して栽培することができる。各子株栽培用プランター３は、図２に示すように、長手方向の一端付近に水を供給する給水口３ａが設けられ、給水口３ａと反対側の他端付近に水を排出する排水口３ｂが設けられて、水Ｗは給水口３ａから排水口３ｂへ向かって流れるように常時循環している。 (Planter 3 for seedling cultivation)
As shown in FIGS. 1 to 3, the planters 3, 3 for cultivating parent stocks are water tanks filled with water W of a predetermined depth, open on the entire top surface, and having a large width in the lateral direction. 2 can be cultivated by immersing it in water W. As shown in FIG. 2, each seedling cultivation planter 3 is provided with a water supply port 3a for supplying water near one end in the longitudinal direction, and a drainage port 3b for discharging water near the other end on the opposite side of the water supply port 3a. is provided, and the water W is constantly circulating so as to flow from the water supply port 3a toward the water discharge port 3b.
　排水口３ｂから排出された水は、育苗システム１の下部に設置した水槽３１に流下し、水槽３１に設けたフィルターで異物を除去し、エアレーション装置（不図示）で溶存酸素が補った後、ポンプ（不図示）で給水口３ａへ送出される。排水口３ｂは、子株栽培用プランター３の底面から突出すると共に上端が開口しているオーバーフロー管で形成されて、子株Ｃの根Ｒｃ（図３）を浸すのに十分な水深を維持している。具体的には、後述するウレタン培地４の上下の厚み寸法と略同じであり、ウレタン培地４に十分吸水させて略全体が水中に沈むようにしたときに、ウレタン培地４の上面が子株栽培用プランター３の水面と略同じ高さとなるように設定されている。 The water discharged from the drain port 3b flows down to the water tank 31 installed at the bottom of the seedling raising system 1, the filter provided in the water tank 31 removes foreign matter, and the dissolved oxygen is supplemented with an aeration device (not shown). It is delivered to the water supply port 3a by a pump (not shown). The drain port 3b is formed by an overflow pipe protruding from the bottom surface of the planter 3 for cultivating seedlings and having an open upper end, and maintains a depth of water sufficient for immersing the roots Rc (Fig. 3) of the seedlings C. . Specifically, it is substantially the same as the vertical thickness dimension of the urethane culture medium 4, which will be described later, and when the urethane culture medium 4 is allowed to absorb sufficient water so that substantially the entirety is submerged in water, the upper surface of the urethane culture medium 4 is a planter for cultivating seedlings. It is set to be approximately the same height as the water surface of 3.
　親株Ｐと子株ＣはランナーＳＲで繋がれて、育苗に必要な養分はランナーＳＲを通じて親株Ｐから各子株Ｃへ供給されており、あとは子株Ｃの発根と培地への活着及び光合成等に必要な水分を与えれば足りるため、子株栽培用プランター３の水Ｗには青粉を発生させるような養分は添加されていない。したがって、親株栽培用プランター２とは異なり、光を照射されても青粉発生の心配がなく、上部を全面的に開口できるものである。なお、図１において、子株栽培用プランター３と下部に設置される水槽やポンプ等とを繋ぐ配管等は省略されている。 Parent strain P and offspring strain C are connected by a runner SR. Nutrients necessary for raising seedlings are supplied from parent strain P to each offspring strain C through the runner SR. Since it is sufficient to supply the required amount of water, the water W in the planter 3 for cultivating seedlings is not added with any nutrients that generate blue powder. Therefore, unlike the planter 2 for cultivating the parent strain, there is no risk of blue powder generation even when exposed to light, and the top can be opened entirely. In addition, in FIG. 1, the piping etc. which connect the planter 3 for seedling cultivation, the water tank installed in the lower part, a pump, etc. are abbreviate|omitted.
（ウレタン培地４）
　ウレタン培地４は、ウレタンスポンジ製の培地であり、直方体形状に形成されていて、上面には、図４に示すように、ランナーＳＲに発生した子株Ｃを挟み込ませるように人手で留めて定着させるスリットＳを設けている。使用するウレタンスポンジは連続気泡構造であり、水中で圧縮して空気を押し出した後で、圧縮状態を解除すれば十分な水を吸水保持できるので、ウレタン培地４に定着させる際には発生間もなく殆ど根が出ていない子株でも、速やかに発根させることができる。また、吸水したウレタン培地４を子株栽培用プランター３に設置し、湛えた水Ｗに浸せば、図３に符号Ｘで示すように、培地の略全体が水中に沈んで、溶存酸素を補われた水が常時供給されるようになり、発根後も継続的な成長が促される。 (Urethane medium 4)
The urethane culture medium 4 is a culture medium made of urethane sponge, and is formed in a rectangular parallelepiped shape, and as shown in FIG. A slit S is provided. The urethane sponge used has an open-cell structure, and after being compressed in water to push out the air, it can absorb and retain a sufficient amount of water by releasing the compressed state. Even seedlings without roots can be rooted quickly. Also, if the urethane medium 4 that has absorbed water is placed in the planter 3 for cultivating seedlings and is immersed in the water W that has been flooded, as indicated by symbol X in FIG. Water is constantly supplied, and continuous growth is promoted even after rooting.
　子株Ｃから発根した根Ｒｃは、成長に伴いウレタンスポンジ内を下向きに伸びてゆき、ウレタン培地４の下面を突き破って発出する。ウレタンスポンジによる抵抗がなくなることで、その後、横方向にも広がるように大きく成長し、取り込める水分量が増えることで、子株全体が更に大きく成長する。しかし、根Ｒｃが発出した後も、ウレタン培地４が水中に沈んだままでは、ウレタン培地４と子株栽培用プランター３の底面の隙間が狭く、根Ｒｃの成長の妨げになる。そこで、根Ｒｃが発出した後は、前記隙間を広げて根Ｒｃの成長を促すため、図３に符号Ｙで示すように、ウレタン培地４に後述する突起体５を取り付ける。 Roots Rc rooted from offspring C extend downward inside the urethane sponge as they grow, break through the lower surface of the urethane medium 4, and emerge. Since the resistance of the urethane sponge disappears, the seedlings grow so as to spread out in the horizontal direction, and the amount of water that can be taken in increases, so that the whole seedling grows even larger. However, if the urethane medium 4 remains submerged in water even after the roots Rc emerge, the gap between the urethane medium 4 and the bottom surface of the planter 3 for cultivating seedlings is narrow, hindering the growth of the roots Rc. Therefore, after the root Rc emerges, in order to widen the gap and promote the growth of the root Rc, as indicated by symbol Y in FIG.
（突起体５）
　突起体５は、プラスチック製で、図５に示すように、概ね丸棒状の脚部５１と、その上部に同心に形成される円盤状の受部５２と、受部５２の上面の中央から真直ぐ突出し、先端に抜け止め５３ａを備えるピン部５３とを有してなる。ピン部５３をウレタン培地４の下面の四隅に差し込めば、図３に符号Ｙで示すように、脚部５１によりウレタン培地４が子株栽培用プランター３の底面との隙間を広げるように浮かされて、その状態で安定的に支持される。これにより、下面から発出した根Ｒｃが成長を妨げられることがなくなる。根の発出部位から外れており、ウレタン培地４を安定的に支持することができれば、ピン部５３は四隅に限らず他の部位に差し込んでも良い。なお、脚部５１の長さが異なるものを複数種類用意しておくことにより、様々な水深に対応することができる。 (Projection 5)
The projecting body 5 is made of plastic and, as shown in FIG. It has a pin portion 53 that protrudes and has a retainer 53a at its tip. When the pin portions 53 are inserted into the four corners of the bottom surface of the urethane culture medium 4, the legs 51 float the urethane culture medium 4 so as to widen the gap between it and the bottom surface of the planter 3 for cultivating seedlings, as indicated by symbol Y in FIG. It is supported stably in that state. As a result, the growth of roots Rc protruding from the lower surface is not hindered. The pin portions 53 may be inserted not only at the four corners but also at other portions as long as the pin portions 53 can stably support the urethane culture medium 4 away from the root-protruding portions. By preparing a plurality of types of leg portions 51 having different lengths, it is possible to cope with various water depths.
（育苗システム１及びそれを用いた育苗方法の特徴）
　上述したイチゴの育苗システム１は、溶存酸素を補われながら循環する水Ｗに子株Ｃを浸して育苗するので、速やかな発根が促され、発根した根Ｒｃに水分補給及び酸素補給が十分に行われて子株Ｃを確実に成長させることができる。土を用いないので、虫が発生しにくい。水には養分が含まれていないので、病原菌が増殖しにくい。そして、水は常時循環しているので、根腐れが発生するリスクが低い。 (Features of the seedling-raising system 1 and the seedling-raising method using it)
In the above-described strawberry seedling-raising system 1, seedlings C are immersed in circulating water W while being supplemented with dissolved oxygen to raise seedlings, so rapid rooting is promoted, and rooted roots Rc are sufficiently hydrated and oxygenated. The offspring C can be reliably grown by performing the following steps. Since no soil is used, it is difficult for insects to grow. Water does not contain nutrients, so it is difficult for pathogens to grow. And since the water is constantly circulating, the risk of root rot occurring is low.
　親株栽培用プランター２の両側に平行配置した二台の子株栽培用プランター３は、各親株Ｐから伸長するランナーＳＲを左右反対方向に振り分けて誘引することができるうえ、各子株栽培用プランター３は、全面開口しており短手方向に十分な幅があるので、ランナーＳＲの取り回しや子株Ｃ（ウレタン培地４）の設置レイアウトの自由度が高い。すなわちランナーどうしが入り組んで絡み合うことを防止するように取り回して、ランナーＳＲから順次発生する子株Ｃを管理することができる。 The two offspring planters 3 arranged in parallel on both sides of the parental strain cultivation planter 2 can distribute and attract the runners SR extending from each parental strain P in the left and right opposite directions. Since the entire surface is open and has a sufficient width in the lateral direction, there is a high degree of freedom in the placement layout of the runner SR and the seedlings C (urethane culture medium 4). In other words, it is possible to manage the offspring C that are sequentially generated from the runner SR by arranging so as to prevent the runners from being complicatedly entangled with each other.
　各子株Ｃは、個別のウレタン培地４に定着させられた状態で子株栽培用プランター３に設置されるので、生育中に他の子株と根が相互に絡み合うことが防止される。また、ウレタン培地４がアンカーのような役割を果たしてランナーＳＲの取り回し位置を安定させるので、ランナーが動いて相互に絡み合うことが防止される。子株ＣをランナーＳＲから切り離してイチゴ苗として使用する場合に、ウレタン培地４が不要であれば、これを切り裂いて容易に除去することもできる。 Each offspring C is installed in the offspring cultivation planter 3 in a state of being fixed in an individual urethane medium 4, so that other offspring and roots are prevented from becoming entangled with each other during growth. Further, the urethane medium 4 serves as an anchor and stabilizes the routing position of the runners SR, thereby preventing the runners from moving and becoming entangled with each other. When the offspring C is separated from the runner SR and used as a strawberry seedling, if the urethane medium 4 is unnecessary, it can be easily removed by cutting it.
　子株Ｃが発生したばかりの初期段階ではウレタン培地４に吸水させて、図３に符号Ｘで示すように、湛えられた水Ｗに浸すことで十分な水と溶存酸素を与えて発根を促す一方、根Ｒｃがウレタン培地４内を下向きに伸びて、ウレタン培地４の下面から発出した後は、図３に符号Ｙで示すように、突起体５を取り付けてウレタン培地４の下面とプランター底面との隙間を広げることで、根Ｒｃの成長用スペースが確保され、また、根Ｒｃが溶存酸素を補充された水に直接晒されることにより、拡大的成長を促されるようになる。なお、突起体５は棒状に形成されているので、根Ｒｃと絡み合うことがなく、子株ＣをランナーＳＲから切り離して苗として取り出すときには、ウレタン培地４から抜き取ることにより容易に除去できる。抜け止め５３ａは、球状に形成されているので、抜き取り作業が行い易い。 At the initial stage when the offspring C has just emerged, the urethane medium 4 is allowed to absorb water, and as indicated by the symbol X in FIG. On the other hand, after the root Rc extends downward in the urethane medium 4 and protrudes from the bottom surface of the urethane medium 4, as indicated by symbol Y in FIG. A space for the growth of the roots Rc is ensured by widening the gap between the roots Rc, and the roots Rc are directly exposed to water supplemented with dissolved oxygen, thereby promoting expansive growth. Since the projections 5 are rod-shaped, they are not entangled with the roots Rc, and when the seedlings C are separated from the runner SR and taken out as seedlings, they can be easily removed by extracting them from the urethane medium 4.例文帳に追加Since the retainer 53a is formed in a spherical shape, it can be easily removed.
（上記実施形態の変形例）
　上記実施形態では、ウレタン培地４に設けたスリットＳに子株Ｃを挟み込むように固定する（図４）こととしたが、スリットに代えて差し込み穴を設けてこれに差し込むように固定しても良く、Ｕ字形の留め具など別の固定部材を用いても良い。ウレタン培地４は、子株栽培用プランターの水深と略同じ厚みがあって安定的に設置できるものであれば、直方体形状に限らず、他の多角柱形や円柱形、その他の形状のものを用いることができる。 (Modification of above embodiment)
In the above embodiment, the seedling C is fixed so as to be inserted into the slit S provided in the urethane medium 4 (Fig. 4), but instead of the slit, an insertion hole may be provided and fixed so as to be inserted into the hole. , U-shaped fasteners, or other securing members may be used. The urethane culture medium 4 is not limited to a rectangular parallelepiped shape, and other shapes such as polygonal prisms, cylinders, and other shapes can be used as long as it has a thickness substantially equal to the water depth of the planter for cultivating seedlings and can be installed stably. be able to.
　上記実施形態では、ウレタン培地４は、培地間の隙間を水路として水が循環し易くなるように、或いは根Ｒｃの成長具合に応じてプランター底面との隙間を個別に広げられるようにするため、分割形成したものに各子株を定着させるようにしたが、例えば水の経路となる溝を上面に設ける等の手当てをして一体形成するようにしても良い。また、ウレタンスポンジに代えて、気泡連続構造を有する他のスポンジを用いても良く、或いは他の吸水性培地を用いても良い。また、培地を用いることなく、例えば透孔やスリットが形成された筒状体を子株栽培用プランターに設置して、その中に子株Ｃを落とし込むように設置し、或いは子株Ｃをそのまま水Ｗに浸すように設置しても良い。 In the above embodiment, the urethane medium 4 is arranged so that water can easily circulate through the gaps between the mediums, or the gaps between the bottom surface of the planter can be individually widened according to the growth of the roots Rc. Although each sub-stalk is fixed to the separately formed one, it may be integrally formed by, for example, providing a groove on the upper surface to serve as a path for water. Further, instead of the urethane sponge, another sponge having an open cell structure may be used, or another water-absorbing medium may be used. In addition, without using a medium, for example, a cylindrical body having a through hole or a slit is installed in a planter for seedling cultivation, and the seedling C is dropped into it, or the seedling C is directly added to the water W. You may install it so that it may be submerged.
　上記実施形態では、突起体５を棒状に形成したが、これに限らず、ウレタン培地４とプランター底面の間に介在して隙間を広げて、根Ｒｃの成長用スペースを確保できるものであれば、他の形状の突起体を用いても良い。また、ウレタン培地４に取り付けるものでなくても、プランター底面に設置されて、ウレタン培地４の下面との間に介在することにより、ウレタン培地をプランター底面から浮かせて隙間を広げられる、他の介在物を用いることにしても良い。 In the above embodiment, the protrusions 5 are formed in a rod shape, but the present invention is not limited to this, as long as the space between the urethane medium 4 and the bottom surface of the planter can be widened to secure a space for the growth of the roots Rc. , other shapes of protrusions may be used. In addition, even if it is not attached to the urethane medium 4, it is installed on the bottom surface of the planter and interposed between the bottom surface of the urethane medium 4 to float the urethane medium from the bottom surface of the planter and widen the gap. You can also use objects.
　上記実施形態及び変形例では、ウレタン培地４から子株Ｃの根Ｒｃが発出した後、根がＲｃの成長用スペースを確保するために、ウレタン培地４とプランター底面の間に物を介在させて根Ｒｃの成長用スペースを確保したが、これに代えて、ウレタン培地４を子株栽培用プランター３から持ち上げて絞るように脱水して空気を多く含ませることにより浮力を与えて、水Ｗに浮かべるようにしても良い。これによれば、物を使用しないので、コストが抑えられて、苗として取り出したときの後始末の負担が少なく済む。 In the above-described embodiment and modification, after the roots Rc of the offspring C emerge from the urethane medium 4, the roots are placed between the urethane medium 4 and the bottom of the planter to secure a space for the growth of Rc. A space for the growth of Rc is secured, but instead of this, the urethane medium 4 is lifted from the seedling cultivation planter 3 and dehydrated by squeezing it to contain a lot of air to give buoyancy and float on the water W. You can do it. According to this method, since no material is used, the cost can be reduced, and the burden of cleaning up after the seedlings are taken out can be reduced.
　上記実施形態において、プランター設置棚は、図１～２に示すように、四本の中央支柱１２・・・１２のうち二本ずつに架け渡された二本の梁１３、１３に対して略垂直に固定される五本の梁１４・・・１４により設けられているが、例えば矩形状棚板の四隅をそれぞれ垂直に立てられた支柱で支持してなる等、様々な形状の棚を用いることができる。なお、棚は一段のみ設置することにしても良く、或いは棚を設けることなく床に直接設置しても良い。その他、本発明はその要旨を逸脱しない範囲で種々の変更をなし得るものである。 In the above-described embodiment, the planter installation shelf, as shown in FIGS. It is provided by five vertically fixed beams 14 . be able to. It should be noted that only one shelf may be installed, or it may be installed directly on the floor without providing a shelf.
