Description

本願発明は、植物の水耕栽培に用いられる植栽ベッドに関するものである。   The present invention relates to a planting bed used for hydroponics of plants.

水耕栽培における栽培手法の一つとして、例えば、特許文献1及び特許文献2に示されるように、板状の植栽ベッドに植物を植栽し、この植栽ベッドを水耕栽培用の養液に浮かべて栽培する手法が知られている。   As one of the cultivation methods in hydroponics, for example, as shown in Patent Document 1 and Patent Document 2, a plant is planted on a plate-shaped planting bed, and this planting bed is used for hydroponics. There is a known technique for growing in a liquid.

この場合、上記植栽ベッドは、所要の浮力を備えることが必要であることから、これを発泡樹脂等の低比重材で板状に一体形成するのが通例である。   In this case, since the planting bed needs to have a required buoyancy, it is a common practice to integrally form it in a plate shape with a low specific gravity material such as foamed resin.

特開平10−271925号公報Japanese Patent Laid-Open No. 10-271925 特開平9−19228号公報。JP-A-9-19228.

ところが、このような植栽ベッドは、植物の栽培中は継続的に養液に浮かべられており、しかも養液温度が植物の生育に適した温度に設定されていること等から、養液中に青藻が発生し、これが上記植栽ベッドの養液浸漬部分に付着して繁殖する。このため、一回の水耕栽培が終了したときには、上記植栽ベッドを養液中から引き上げてその表面に付着した青藻を清掃によって除去し、次回の水耕栽培に備えることが必要となる。   However, such a planting bed is continuously floated in the nutrient solution during plant cultivation, and the nutrient solution temperature is set to a temperature suitable for plant growth. Blue algae are generated in the plant, and this adheres to the nutrient solution immersion part of the planting bed and propagates. For this reason, when one hydroponics is completed, it is necessary to pull up the planting bed from the nutrient solution and remove the blue algae attached to the surface by cleaning to prepare for the next hydroponics. .

この場合、青藻は、植栽ベッドの表面への付着力が強く、特に上記植栽ベッドが最も一般的な成形素材である発泡樹脂材で成形されている場合には、発泡粒の粒界溝に侵入した状態で繁殖することから、その除去作業が困難で、多大の作業時間を要し、その結果、水耕栽培全体を通じての作業効率が低下し、栽培コストの上昇を招来することになる。   In this case, the green algae has strong adhesion to the surface of the planting bed, and particularly when the planting bed is formed of a foamed resin material, which is the most common molding material, Because it propagates in a state where it has entered the groove, its removal work is difficult and requires a lot of work time, resulting in a decrease in work efficiency throughout the hydroponics and an increase in cultivation costs. Become.

また、青藻の除去作業の効率を上げるべく、比較的強い力で植栽ベッドの表面を擦ると、該植栽ベッドの発泡粒が粒界部分で破断分離して次第にその形状が損なわれその耐久性が低下するとか、場合によっては植栽ベッドが折損してその使用が不可能になることもあり、水耕栽培におけるランニングコストの上昇を招来する一因にもなる。   In addition, when the surface of the planting bed is rubbed with a relatively strong force in order to increase the efficiency of removing the blue algae, the foamed grains of the planting bed break and separate at the grain boundary part, and the shape is gradually damaged. If the durability is lowered or the planting bed is broken in some cases, the use of the bed becomes impossible, which causes a rise in running cost in hydroponics.

一方、養液の液面上に植栽ベッドを浮置して植物の水耕栽培を行なう場合、該養液の温度は植物の生育条件に対応した温度に設定されることが望ましく、係る要求に応えるべく、空気調和装置によって栽培空間の環境温度を調整する場合がある。この場合、本来的には、空調環境における空気と養液との間の熱移動によって該養液の温度も環境温度に対応するように自動的に温度調整されるが、実際的には、養液の液面は断熱性の高い発泡樹脂材からなる植栽ベッドによって覆われていることから、養液の温度調整は殆ど実効のないものとなっている。   On the other hand, when the plant is hydroponically cultivated with the planting bed suspended on the surface of the nutrient solution, it is desirable that the temperature of the nutrient solution is set to a temperature corresponding to the growth conditions of the plant. In some cases, the environmental temperature of the cultivation space is adjusted by an air conditioner. In this case, originally, the temperature of the nutrient solution is automatically adjusted so as to correspond to the environmental temperature by heat transfer between the air and the nutrient solution in an air-conditioned environment. Since the liquid level of the liquid is covered with a planting bed made of a foamed resin material having high heat insulating properties, the temperature adjustment of the nutrient solution is almost ineffective.

また、空気調和装置による環境温度の調整が行なわれていない栽培環境下においては、例えば、空気温度によっては、養液との間の熱移動を促進させたい場合と、熱移動を抑制したい場合とが起こり得るが、植栽ベッドが断熱性の高い発泡樹脂材で構成されている場合には、少なくとも室内空気と養液との間の熱移動を促進することには対処できないことになる。   Moreover, in the cultivation environment where the adjustment of the environmental temperature by the air conditioner is not performed, for example, depending on the air temperature, the case where it is desired to promote the heat transfer between the nutrient solution and the case where it is desired to suppress the heat transfer. However, when the planting bed is made of a highly heat-insulating foamed resin material, at least the heat transfer between the indoor air and the nutrient solution cannot be promoted.

そこで本願発明では、表面に付着した青藻の清掃が容易で且つ耐久性にも優れ、水耕栽培全体としてのランニングコストを低く抑えることができるとともに、養液温度の調整性能にも優れた水耕栽培の植栽ベッドを提供することを目的としてなされたものである。   Therefore, in the present invention, water that is easy to clean blue algae attached to the surface and excellent in durability, can reduce the running cost of the entire hydroponics, and is excellent in adjusting the nutrient solution temperature. It was made for the purpose of providing a cultivation bed.

本願発明ではかかる課題を解決するための具体的手段として次のような構成を採用している。   In the present invention, the following configuration is adopted as a specific means for solving such a problem.

本願の第1の発明に係る水耕栽培の植栽ベッドでは、樹脂板材又は金属板材によって、底壁1aと該底壁1aの周囲から立ち上がる周壁1bと上記底壁1aの下面に開口して上方へ立ち上がる多数の筒状の植栽部1cを形成したことを特徴としている。   In the hydroponics planting bed according to the first invention of the present application, the resin plate material or the metal plate material opens to the bottom wall 1a, the peripheral wall 1b rising from the periphery of the bottom wall 1a, and the bottom surface of the bottom wall 1a. It is characterized in that a large number of cylindrical planting parts 1c that rise up to are formed.

本願の第2の発明に係る水耕栽培の植栽ベッドでは、上記第1の発明に係る水耕栽培の植栽ベッドにおいて、上記各植栽部1c間に断熱材5を設けたことを特徴としている。   In the hydroponics planting bed according to the second invention of the present application, the heat insulating material 5 is provided between the planting parts 1c in the hydroponics planting bed according to the first invention. It is said.

本願の第3の発明に係る水耕栽培の植栽ベッドでは、上記第1の発明に係る水耕栽培の植栽ベッドにおいて、上記各植栽部1c間に断熱空間4を設けたことを特徴としている。   In the hydroponics planting bed according to the third invention of the present application, in the hydroponics planting bed according to the first invention, a heat insulating space 4 is provided between the planting parts 1c. It is said.

本願発明では次のような効果が得られる。
(a) 本願の第1の発明に係る水耕栽培の植栽ベッドは、樹脂板材又は金属板材によって、底壁1aと該底壁1aの周囲から立ち上がる周壁1bと上記底壁1aの下面に開口して上方へ立ち上がる多数の筒状の植栽部1cを形成した浮体構造をもつことから、これを養液の液面上に浮かべることができ、しかもこの状態では上記植栽部1c内に養液が進入している。従って、上記植栽部1c内に植物20を植栽すると、該植物20の根部分は養液に浸漬されることとなり、該植物20の水耕栽培が促進される。
In the present invention, the following effects can be obtained.
(A) The hydroponics planting bed according to the first invention of the present application is opened to the bottom wall 1a, the peripheral wall 1b rising from the periphery of the bottom wall 1a, and the lower surface of the bottom wall 1a by a resin plate material or a metal plate material. Since it has a floating structure in which a large number of cylindrical planting parts 1c rising upward are formed, it can be floated on the surface of the nutrient solution, and in this state, it is fed in the planting part 1c. Liquid has entered. Therefore, when the plant 20 is planted in the planting part 1c, the root portion of the plant 20 is immersed in the nutrient solution, and hydroponics of the plant 20 is promoted.

そして、係る水耕栽培に用いられる植栽ベッド1においては、以下のような特有の効果が得られる。
(a−1) 上記植栽ベッド1が、樹脂板材又は金属板材によって形成されその表面が滑らかであることから、青藻の付着は植栽ベッド1の表面側に限られ、例えば、従来の発泡樹脂製の植栽ベッド1のように青藻が表面側のみに止まらず発泡粒界にまで侵入して繁殖するということがなく、青藻の除去作業を容易且つ迅速に行なうことができ、清掃作業の効率化及び清掃時間の短縮化が図られる。
And in the planting bed 1 used for the hydroponics which concerns, the following peculiar effects are acquired.
(A-1) Since the planting bed 1 is formed of a resin plate or a metal plate and the surface thereof is smooth, the adhesion of blue algae is limited to the surface side of the planting bed 1, for example, conventional foaming The algae does not stop on the surface side like the resin planting bed 1 and does not penetrate into the foaming grain boundary and propagate, and the algae can be removed easily and quickly. Work efficiency and cleaning time are shortened.

また、上記植栽ベッド1が樹脂板材又は金属板材によって形成されているため、その剛性が高く、従来の発泡樹脂製の植栽ベッドのような青藻清掃時における損傷とか欠損、あるいは折損が生じることが極めて少なく、その耐久性が向上する。これらの相乗効果として、水耕栽培全体としてのランニングコストの低減が図られる。
(a−2) 養液の液面上に植栽ベッド1を浮かべた場合、該植栽ベッド1によって養液の表面が覆われ、該養液が空気と接する面積、即ち、養液から空気中への放熱作用、あるいは空気から養液側への吸熱作用に関与する面積が小さくなり、そのため、係る放熱あるいは吸熱は植栽ベッド1を介しての熱伝導による熱移動に依存せざるを得ない。この場合、従来のように上記植栽ベッド1を発泡樹脂材で形成した場合には、該発泡樹脂材が高い断熱性をもつことから、該植栽ベッド部分での伝熱促進は殆ど望めない。
Moreover, since the said planting bed 1 is formed with the resin plate material or the metal plate material, the rigidity is high, and the damage, a defect | deletion, or breakage at the time of blue algae cleaning like the planting bed made from a conventional foaming resin arises. The durability is improved. As a synergistic effect, the running cost of the entire hydroponics can be reduced.
(A-2) When the planting bed 1 is floated on the liquid level of the nutrient solution, the surface of the nutrient solution is covered by the planting bed 1, and the area where the nutrient solution is in contact with air, that is, from the nutrient solution to the air The area involved in the heat dissipation action to the inside or the heat absorption action from the air to the nutrient solution side is reduced, so that the heat dissipation or heat absorption must depend on the heat transfer by heat conduction through the planting bed 1. Absent. In this case, when the planting bed 1 is formed of a foamed resin material as in the conventional case, since the foamed resin material has high heat insulating properties, almost no heat transfer can be expected at the planting bed portion. .

ところが、本願発明の植栽ベッド1では、該植栽ベッド1を養液の液面上に浮かべた状態において該養液と接する底壁1aが樹脂板材又は金属板材によって形成されていることから、従来のような発泡樹脂製の植栽ベッドに比して、その熱伝導による伝熱性が高いものとなっている。このため、例えば、養液温度が空気温度に比して高いような場合には、養液側の熱が上記植栽ベッド1の底壁1aを熱伝導によって移動して空気中に放熱され養液温度の低下が図られ、逆に、養液温度が空気温度に比して低いような場合には、空気側の熱が上記植栽ベッド1の底壁1aを熱伝導によって移動して養液側へ放熱され養液温度の上昇が図られるなど、養液温度及び植物20の周辺の空気温度の管理が自動的に行なわれ、植物20の育成に好適な環境が容易に得られる。
(b) 本願の第2の発明に係る水耕栽培の植栽ベッドによれば、上記(a)に記載の効果に加えて、以下のような特有の効果が得られる。即ち、この発明では、上記各植栽部1c間に断熱材5を設けているので、上記植栽ベッド1全体としての断熱性は、上記断熱材5を設けたことで高くなっている。このため、例えば、空気温度が養液温度に比して低く、養液側の保温を図りたい場合とか、空気温度が養液温度に比して高く、養液側の昇温を抑制したい場合には、上記断熱材5の断熱作用によって空気側と養液側との間の熱移動が抑制されることでこれが実現され、植物20の育成に好適な環境が容易に得られる。
(c) 本願の第3の発明に係る水耕栽培の植栽ベッドによれば、 本願の第3の発明に係る水耕栽培の植栽ベッドでは、上記(a)に記載の効果に加えて、以下のような特有の効果が得られる。即ち、この発明では、上記(a)に記載の効果に加えて、以下のような特有の効果が得られる。即ち、この発明では、上記各植栽部1c間に断熱空間4を設けているので、上記植栽ベッド1全体としての断熱性は、上記断熱空間4における空気断熱効果の分だけ高くなっている。このため、例えば、空気温度が養液温度に比して低く、養液側の保温を図りたい場合とか、空気温度が養液温度に比して高く、養液側の昇温を抑制したい場合には、上記断熱空間4の断熱作用によって空気側と養液側との間の熱移動が抑制されることでこれが実現され、植物20の育成に好適な環境が容易に得られる。
However, in the planting bed 1 of the present invention, the bottom wall 1a in contact with the nutrient solution in the state where the planting bed 1 is floated on the surface of the nutrient solution is formed of a resin plate material or a metal plate material. Compared to a conventional foaming resin planting bed, the heat conductivity is high. For this reason, for example, when the nutrient solution temperature is higher than the air temperature, the nutrient solution side heat moves through the bottom wall 1a of the planting bed 1 by heat conduction and is dissipated into the air. When the temperature of the liquid is lowered and the temperature of the nutrient solution is lower than the temperature of the air, the heat on the air side moves through the bottom wall 1a of the planting bed 1 by heat conduction and nourishes. The management of the nutrient solution temperature and the temperature of the air around the plant 20 is automatically performed such that the nutrient solution temperature is increased by releasing heat to the solution side, and an environment suitable for growing the plant 20 can be easily obtained.
(B) According to the planting bed of hydroponics according to the second invention of the present application, in addition to the effect described in the above (a), the following specific effects are obtained. That is, in this invention, since the heat insulating material 5 is provided between each said planting part 1c, the heat insulating property as the said planting bed 1 whole has become high by providing the said heat insulating material 5. FIG. For this reason, for example, when the air temperature is lower than the nutrient solution temperature and you want to keep the nutrient solution side warm, or when the air temperature is higher than the nutrient solution temperature and you want to suppress the temperature increase on the nutrient solution side In addition, this is realized by suppressing the heat transfer between the air side and the nutrient solution side by the heat insulating action of the heat insulating material 5, and an environment suitable for growing the plant 20 can be easily obtained.
(C) According to the hydroponics planting bed according to the third invention of the present application, in the hydroponics planting bed according to the third invention of the present application, in addition to the effect described in (a) above The following unique effects can be obtained. That is, in the present invention, in addition to the effect described in the above (a), the following specific effects can be obtained. That is, in this invention, since the heat insulation space 4 is provided between each said planting part 1c, the heat insulation as the said planting bed 1 whole is high only by the part of the air heat insulation effect in the said heat insulation space 4. . For this reason, for example, when the air temperature is lower than the nutrient solution temperature and you want to keep the nutrient solution side warm, or when the air temperature is higher than the nutrient solution temperature and you want to suppress the temperature increase on the nutrient solution side In addition, this is realized by suppressing the heat transfer between the air side and the nutrient solution side by the heat insulating action of the heat insulating space 4, and an environment suitable for growing the plant 20 can be easily obtained.

以下、本願発明を好適な実施形態に基づいて具体的に説明する。
A:第1の実施形態
図1〜図3には、本願発明の第1の実施形態に係る植栽ベッド1を使用した水耕栽培装置の要部を示している。この水耕栽培装置においては、栽培室(図示省略)内に設置された栽培棚10の各段の受台11の上面側に次述の養液容器2を載置する一方、その下面側には照明器12を取付け、該照明器12からの照明光を上記養液容器2側へ照射するようになっている。
Hereinafter, the present invention will be specifically described based on preferred embodiments.
A: 1st Embodiment In FIGS. 1-3, the principal part of the hydroponic cultivation apparatus which uses the planting bed 1 which concerns on the 1st Embodiment of this invention is shown. In this hydroponic cultivation apparatus, the nutrient solution container 2 described below is placed on the upper surface side of the cradle 11 of each stage of the cultivation shelf 10 installed in the cultivation room (not shown), while the lower surface side thereof is placed. Is equipped with an illuminator 12 and irradiates illumination light from the illuminator 12 to the nutrient solution container 2 side.

上記養液容器2は、図1及び図2に示すように長矩形の平面形体をもつ上面開放容器であって、その中には養液3が所定量投入されている。この養液容器2内の養液3の液面には、本願発明の要旨である次述の植栽ベッド1が浮かべられている。   As shown in FIGS. 1 and 2, the nutrient solution container 2 is an open top container having an oblong planar shape, and a predetermined amount of nutrient solution 3 is charged therein. The planting bed 1 described below, which is the gist of the present invention, is floated on the liquid surface of the nutrient solution 3 in the nutrient solution container 2.

上記植栽ベッド1は、図2及び図3に示すように、長矩形の平面形体をもつ底壁1aと該底壁1aの周囲から立ち上がる周壁1bを備えた矩形薄皿状の浮体構造をもつもので、樹脂板材又は金属板材によって一体形成されている。さらに、上記底壁1aには、該底壁1aの下面に開口してここから上方へ立ち上がる円筒状の植栽部1cが所定間隔で多数形成されている。尚、上記周壁1bの高さ寸法は、上記植栽ベッド1に所要数の植物20を植栽した状態で該植栽ベッド1を養液の液面上に浮置させるに十分な排水量を確保し得るように、適宜設定される。また、上記植栽部1cの上面高さは、上記周壁1bの上面高さと略同じとなるように設定されている。   As shown in FIGS. 2 and 3, the planting bed 1 has a rectangular thin dish-like floating body structure including a bottom wall 1a having a long rectangular planar shape and a peripheral wall 1b rising from the periphery of the bottom wall 1a. It is integrally formed of a resin plate material or a metal plate material. Furthermore, the bottom wall 1a is formed with a large number of cylindrical planting portions 1c that open to the lower surface of the bottom wall 1a and rise upward from the bottom wall 1a at predetermined intervals. In addition, the height dimension of the said surrounding wall 1b ensures the amount of drainage sufficient to make this planting bed 1 float on the liquid level of a nutrient solution in the state which planted the required number of plants 20 in the said planting bed 1. It is set as appropriate. Moreover, the upper surface height of the planting part 1c is set to be substantially the same as the upper surface height of the peripheral wall 1b.

上記植栽ベッド1を上記養液容器2内の養液の液面に浮かべた場合、上記植栽部1cは上記養液容器2の底面側に臨んで開口し、且つ該植栽部1cの内部には、上記植栽ベッド1全体の喫水高さに対応する高さまで養液が進入する。そして、この植栽部1cには、植物20がその根保持部20aを投入係止させた状態で、植栽される。従って、上記植物20の根保持部20aは養液に浸漬され、該植物20の育成が図られる。   When the planting bed 1 is floated on the liquid level of the nutrient solution in the nutrient solution container 2, the planting part 1 c opens toward the bottom side of the nutrient solution container 2, and the planting part 1 c The nutrient solution enters the interior up to a height corresponding to the draft height of the entire planting bed 1. And in this planting part 1c, the plant 20 is planted in the state which made the root holding | maintenance part 20a lock. Therefore, the root holding part 20a of the plant 20 is immersed in the nutrient solution, and the plant 20 is grown.

このように植物20が植栽された上記植栽ベッド1は、図1に示すように、上記養液容器2の養液表面上に所定数が順次浮置される。この状態においては、上記養液容器2の養液3の液面が上記各植栽ベッド1によって略覆われ、養液3の液面は殆ど上方に露出しない状態となる。このため、上記養液3と上記植栽ベッド1の周辺の空気との間における熱移動は、上記植栽ベッド1を介する熱伝導に依存することになる。   As shown in FIG. 1, a predetermined number of the planting beds 1 on which the plants 20 are planted are sequentially levitated on the nutrient solution surface of the nutrient solution container 2. In this state, the liquid level of the nutrient solution 3 in the nutrient solution container 2 is substantially covered with the planting beds 1, and the level of the nutrient solution 3 is hardly exposed upward. For this reason, the heat transfer between the nutrient solution 3 and the air around the planting bed 1 depends on heat conduction through the planting bed 1.

この場合、上記植栽ベッド1部分においては、養液3とその上方側の空気とが該植栽ベッド1の底壁1aを介して接しており、しかも該底壁1aは樹脂板材又は金属板材で構成されており、その熱伝導による伝熱性は、該植栽ベッド1が発泡樹脂材で構成されている場合に比して、高くなっている。   In this case, in the planting bed 1 part, the nutrient solution 3 and the air above it are in contact via the bottom wall 1a of the planting bed 1, and the bottom wall 1a is a resin plate material or a metal plate material. The heat conductivity due to the heat conduction is higher than when the planting bed 1 is made of a foamed resin material.

このため、例えば、養液温度が空気温度に比して高いような場合には、養液3側の熱が上記植栽ベッド1の底壁1aを熱伝導によって移動して空気中に放熱され養液温度の低下が図られる。逆に、養液温度が空気温度に比して低いような場合には、空気側の熱が上記植栽ベッド1の底壁1aを熱伝導によって移動して養液3側へ放熱され養液温度の上昇が図られる。これらの結果、養液温度及び植物20の周辺の空気温度の管理が自動的に行なわれ、植物20の育成に好適な環境が容易に得られる。   For this reason, for example, when the nutrient solution temperature is higher than the air temperature, the heat on the nutrient solution 3 side moves through the bottom wall 1a of the planting bed 1 by heat conduction and is radiated into the air. The nutrient solution temperature is reduced. Conversely, when the nutrient solution temperature is lower than the air temperature, the heat on the air side moves through the bottom wall 1a of the planting bed 1 by heat conduction and is dissipated to the nutrient solution 3 side. The temperature is increased. As a result, the nutrient solution temperature and the air temperature around the plant 20 are automatically managed, and an environment suitable for growing the plant 20 can be easily obtained.

一方、植栽ベッド1は、植物の栽培中は継続的に養液3に浮置されていることから、養液中に発生した青藻が該植栽ベッド1の養液浸漬部分に付着して繁殖する。このため、水耕栽培の終了時にはこれを養液3から引き上げてその表面に付着した青藻を除去する清掃作業が必要となることは既述の通りである。   On the other hand, since the planting bed 1 is continuously levitated in the nutrient solution 3 during the cultivation of the plant, the blue algae generated in the nutrient solution adhere to the nutrient solution immersion part of the planting bed 1. Breed. For this reason, as described above, at the end of hydroponics, it is necessary to carry out a cleaning operation to remove the blue algae attached to the surface by lifting it from the nutrient solution 3.

この場合、この実施形態の植栽ベッド1では、これが、樹脂板材又は金属板材によって形成されその表面が滑らかであることから、青藻の付着は植栽ベッド1の表面側に限られ、例えば、従来の発泡樹脂製の植栽ベッドのように青藻が表面側のみに止まらず発泡粒界にまで侵入して繁殖するということがなく、青藻の除去作業を容易且つ迅速に行なうことができ、清掃作業の効率化及び清掃時間の短縮化が図られることになる。   In this case, in the planting bed 1 of this embodiment, since this is formed of a resin plate material or a metal plate material and the surface thereof is smooth, adhesion of blue algae is limited to the surface side of the planting bed 1, for example, The green algae can be removed easily and quickly without the blue algae growing on the surface of the foamed grain boundary and growing like the conventional foaming resin planting beds. Thus, the efficiency of the cleaning work and the shortening of the cleaning time are achieved.

また、上記植栽ベッド1が樹脂板材又は金属板材によって形成されているため、その剛性が高く、従来の発泡樹脂製の植栽ベッドのような青藻清掃時における損傷とか欠損、あるいは折損が生じることが極めて少ないことから、その耐久性が向上する。これらの相乗効果として、水耕栽培全体としてのランニングコストの低減が促進される。
B:第2の実施形態
図4及び図5には、本願発明の第2の実施形態に係る植栽ベッド1を示している。この植栽ベッド1は、上記第1の実施形態における植栽ベッド1に、次述の断熱材5を取付けて構成されるものである。
Moreover, since the said planting bed 1 is formed with the resin plate material or the metal plate material, the rigidity is high, and the damage, a defect | deletion, or breakage at the time of blue algae cleaning like the planting bed made from a conventional foaming resin arises. Therefore, the durability is improved. As these synergistic effects, reduction of the running cost as the whole hydroponics is promoted.
B: Second Embodiment FIGS. 4 and 5 show a planting bed 1 according to a second embodiment of the present invention. This planting bed 1 is configured by attaching the following heat insulating material 5 to the planting bed 1 in the first embodiment.

即ち、上記植栽ベッド1は、長矩形の平面形体をもつ底壁1aと該底壁1aの周囲から立ち上がる周壁1bを備えた矩形薄皿状の浮体構造をもつもので、樹脂板材又は金属板材によって一体形成されている。さらに、上記底壁1aには、該底壁1aの下面に開口してここから上方へ立ち上がる円筒状の植栽部1cが所定間隔で多数形成されている。   That is, the planting bed 1 has a rectangular thin dish-like floating body structure including a bottom wall 1a having a long rectangular planar shape and a peripheral wall 1b rising from the periphery of the bottom wall 1a. Are integrally formed. Furthermore, the bottom wall 1a is formed with a large number of cylindrical planting portions 1c that open to the lower surface of the bottom wall 1a and rise upward from the bottom wall 1a at predetermined intervals.

この植栽ベッド1においては、上記底壁1a上に形成された多数の植栽部1cの周囲は単なる空間とされており、該底壁1aの下面側には養液3が、上面側には周辺の空気が、それぞれ接触される構成であり、該底壁1aは良伝熱部とされている。しかし、このような構成では、上記植栽ベッド1の下面側と上面側との間における伝熱性を抑えたいような場合には、対応できないことになる。   In this planting bed 1, the periphery of a large number of planting parts 1c formed on the bottom wall 1a is merely a space, and the nutrient solution 3 is placed on the lower surface side of the bottom wall 1a and the upper surface side. Is a configuration in which ambient air is in contact with each other, and the bottom wall 1a is a good heat transfer section. However, such a configuration cannot cope with the case where it is desired to suppress heat transfer between the lower surface side and the upper surface side of the planting bed 1.

そこで、この実施形態では、上記植栽ベッド1を、伝熱性が要求される場合と、伝熱性は要求されず、それよりも断熱性が要求されるような場合の何れにおいても選択して使用できるようにしたものである。即ち、図4に示すように、上記植栽ベッド1の内周形状に沿った長矩形の平面形体を有するとともに、上記植栽ベッド1の各植栽部1cに対応する部位には該植栽部1cの外側に嵌合可能な大きさの孔6,6、・・を備えた発泡樹脂製の断熱材5を用意し、該断熱材5を上記植栽ベッド1に対して着脱可能としたものである。   Therefore, in this embodiment, the planting bed 1 is selected and used in both cases where heat transfer is required and where heat transfer is not required and heat insulation is required more than that. It is something that can be done. That is, as shown in FIG. 4, while having a long rectangular planar shape along the inner peripheral shape of the planting bed 1, the planting is provided at a site corresponding to each planting part 1c of the planting bed 1. A foamed resin heat insulating material 5 provided with holes 6, 6,... Sized to fit outside the portion 1 c is prepared, and the heat insulating material 5 can be attached to and detached from the planting bed 1. Is.

上記植栽ベッド1に上記断熱材5を嵌合装着した状態を図5に示している。この状態では、上記植栽ベッド1の底壁1aと上記断熱材5とが一体化され、これら両者で構成される部分は、該断熱材5が有する断熱性の分だけ全体としての断熱性が高くなっている。   FIG. 5 shows a state in which the heat insulating material 5 is fitted and attached to the planting bed 1. In this state, the bottom wall 1a of the planting bed 1 and the heat insulating material 5 are integrated, and the portion constituted by both has a heat insulating property as a whole by the heat insulating property of the heat insulating material 5. It is high.

従って、例えば、空気温度が養液温度に比して低く、且つ養液温度が植物20の生育に適した温度であって、養液側の保温を図りたい場合とか、逆に、空気温度が養液温度に比して高く、且つ養液温度が植物20の生育に適した温度であって、養液側の昇温を抑制したい場合には、上記断熱材5の断熱作用によって空気側と養液側との間の熱伝導による熱移動が抑制されることで実現され、植物20の育成に好適な環境が容易に得られることになる。また、上記断熱材5を取外した状態では、上記第1の実施形態に係る植栽ベッド1と同様の作用効果が得られる。   Therefore, for example, when the air temperature is lower than the nutrient solution temperature and the nutrient solution temperature is suitable for the growth of the plant 20 and it is desired to keep the nutrient solution side warm, conversely, the air temperature is When it is higher than the nutrient solution temperature and the nutrient solution temperature is suitable for the growth of the plant 20 and it is desired to suppress the temperature rise on the nutrient solution side, An environment suitable for growing the plant 20 can be easily obtained by suppressing heat transfer due to heat conduction with the nutrient solution side. Moreover, in the state which removed the said heat insulating material 5, the effect similar to the planting bed 1 which concerns on the said 1st Embodiment is obtained.

即ち、この実施形態の植栽ベッド1では、上記断熱材5を設けるか、設けないか、によって、断熱性に優れた植栽ベッド1と伝熱性に優れた植栽ベッド1を選択的に構成することができ、栽培対象たる植物20の種類に対する対応が容易となる。   That is, in the planting bed 1 of this embodiment, the planting bed 1 having excellent heat insulation and the planting bed 1 having excellent heat conductivity are selectively configured depending on whether the heat insulating material 5 is provided or not. This makes it easy to cope with the type of plant 20 to be cultivated.

尚、上記以外の作用効果については、上記第1の実施形態の場合と同様であるので、該第1の実施形態における該当説明を援用し、ここでの説明を省略する。
C:第3の実施形態
図6及び図7には、本願発明の第3の実施形態に係る植栽ベッド1を示している。この植栽ベッド1は、上記第1の実施形態における植栽ベッド1に、次述の上壁1dを取付けて構成されるものである。
In addition, since it is the same as that of the case of the said 1st Embodiment about the effect other than the above, the applicable description in this 1st Embodiment is used and description here is abbreviate | omitted.
C: Third Embodiment FIGS. 6 and 7 show a planting bed 1 according to a third embodiment of the present invention. The planting bed 1 is configured by attaching the upper wall 1d described below to the planting bed 1 in the first embodiment.

即ち、上記植栽ベッド1は、長矩形の平面形体をもつ底壁1aと該底壁1aの周囲から立ち上がる周壁1bを備えた矩形薄皿状の浮体構造をもつもので、樹脂板材又は金属板材によって一体形成されている。さらに、上記底壁1aには、該底壁1aの下面に開口してここから上方へ立ち上がる円筒状の植栽部1cが所定間隔で多数形成されている。   That is, the planting bed 1 has a rectangular thin dish-like floating body structure including a bottom wall 1a having a long rectangular planar shape and a peripheral wall 1b rising from the periphery of the bottom wall 1a. Are integrally formed. Furthermore, the bottom wall 1a is formed with a large number of cylindrical planting portions 1c that open to the lower surface of the bottom wall 1a and rise upward from the bottom wall 1a at predetermined intervals.

この植栽ベッド1においては、上記底壁1a上に形成された多数の植栽部1cの周囲は単なる空間とされており、該底壁1aの下面側には養液3が、上面側には周辺の空気が、それぞれ接触される構成であり、該底壁1aは良伝熱部とされている。しかし、このような構成では、上記植栽ベッド1の下面側と上面側との間における伝熱性を抑えたいような場合には、対応できないことになる。   In this planting bed 1, the periphery of a large number of planting parts 1c formed on the bottom wall 1a is merely a space, and the nutrient solution 3 is placed on the lower surface side of the bottom wall 1a and the upper surface side. Is a configuration in which ambient air is in contact with each other, and the bottom wall 1a is a good heat transfer section. However, such a configuration cannot cope with the case where it is desired to suppress heat transfer between the lower surface side and the upper surface side of the planting bed 1.

そこで、この実施形態では、上記植栽ベッド1を、伝熱性が要求される場合に使用するに好適なものとして構成したものである。即ち、上記底壁1aと周壁1b及び植栽部1cを備えて構成される上記植栽ベッド1の上面開口部分に、該植栽ベッド1の外形形状に沿った長矩形の板材で構成され且つ上記植栽部1cに対応する部位に該植栽部1cに嵌合する多数の孔1eを設けた上壁1dを衝合させ、これら両者を溶接接合にて一体化したものである。従って、上記上壁1dの取付け状態においては、該上壁1dと上記植栽ベッド1の間に、断熱空間4が形成される。   Therefore, in this embodiment, the planting bed 1 is configured to be suitable for use when heat transfer is required. That is, the upper surface opening portion of the planting bed 1 configured to include the bottom wall 1a, the peripheral wall 1b, and the planting portion 1c is formed of a long rectangular plate material along the outer shape of the planting bed 1 and An upper wall 1d provided with a large number of holes 1e fitted to the planting part 1c is brought into contact with a part corresponding to the planting part 1c, and these two parts are integrated by welding. Therefore, in the attached state of the upper wall 1d, a heat insulating space 4 is formed between the upper wall 1d and the planting bed 1.

このように、上記植栽ベッド1を、上記上壁1dの付設によって密閉容器体としその内部に断熱空間4を設けることで、上記植栽ベッド1全体としての断熱性は、上記断熱空間4における空気断熱効果の分だけ高くなっている。このため、例えば、空気温度が養液温度に比して低く、養液側の保温を図りたい場合とか、空気温度が養液温度に比して高く、養液側の昇温を抑制したい場合には、上記断熱空間4の断熱作用によって空気側と養液側との間の熱移動が抑制されることで実現され、植物20の育成に好適な環境が容易に得られる。   As described above, the planting bed 1 is formed as a sealed container body by attaching the upper wall 1d, and the heat insulating space 4 is provided in the inside thereof. The air insulation effect is higher. For this reason, for example, when the air temperature is lower than the nutrient solution temperature and you want to keep the nutrient solution side warm, or when the air temperature is higher than the nutrient solution temperature and you want to suppress the temperature increase on the nutrient solution side In this case, the heat transfer between the air side and the nutrient solution side is suppressed by the heat insulating action of the heat insulating space 4, and an environment suitable for growing the plant 20 can be easily obtained.

尚、上記以外の作用効果については、上記第1の実施形態の場合と同様であるので、該第1の実施形態における該当説明を援用し、ここでの説明を省略する。   In addition, since it is the same as that of the said 1st Embodiment about the effect other than the above, the pertinent description in this 1st Embodiment is used and description here is abbreviate | omitted.

また、この実施形態では上記上壁1dを上記植栽ベッド1に溶接接合しているが、他の実施形態では、例えば、上記上壁1dを上記植栽ベッド1に対してボルト締着等によって着脱自在に構成することもできる。係る構成とした場合には、上記上壁1dの着脱によって断熱性に優れた植栽ベッド1と伝熱性に優れた植栽ベッド1を選択的に構成することができ、栽培対象たる植物20の種類に対する対応が容易となる。   In this embodiment, the upper wall 1d is welded to the planting bed 1, but in other embodiments, for example, the upper wall 1d is bolted to the planting bed 1 or the like. It can also be configured to be detachable. In the case of such a configuration, the planting bed 1 having excellent heat insulation and the planting bed 1 having excellent heat conductivity can be selectively configured by attaching and detaching the upper wall 1d. It becomes easy to correspond to the type.
