Description

本願発明は、水草の一種のヒシ(菱)を、自然環境下ではなく、人工的に設備された栽培環境化において栽培するためのヒシの栽培装置に関するものである。   The present invention relates to an apparatus for cultivating an apricot for cultivating a kind of water plant (hizhi) in an artificially installed cultivation environment, not in a natural environment.

ヒシは水草の一種で、池、湖沼、クリーク等の比較的水深の浅いところ(約1.5m〜2.0m未満)に自生する一年草であり、小ヒシ、中ヒシ、オニヒシ(唐ヒシ)等の種類が知られている。このヒシの実は、でんぷん質で、しかも有機ゲルマニュムを含む数少ない植物であることから、古来、食用に、あるいは漢方生薬として珍重され、特に近年では、生食するほかに、焼酎、菓子、茶等に加工されて、ダイエット食品、がん抑制サプリメント品として製造・販売され、注目を集めている。   Hishi is a kind of aquatic grass, and is an annual grass that grows in relatively shallow places (about 1.5m to less than 2.0m), such as ponds, lakes, and creeks. ) Etc. are known. Since the seeds are starchy and are rare in the presence of organic germanium, they have long been valued as edible or herbal medicines. It has been produced and sold as diet foods and cancer control supplements, and has attracted attention.

ところで、元来、ヒシは、湖沼とかクリーク等に自生したものをその結実時期に実を採取して利用するのが一般的であったが、係る自生状態では生育状態の管理ができず収穫作業も難しく、しかも収穫量も少ない等の欠点があるところに、国の農業政策の一環としての減反政策が進められ、これに相俟って、減反した田圃でヒシを栽培する試みが九州の福岡県とか佐賀県を中心に行われている(非特許文献1参照)。なお、現在、ヒシの国内生産量は少なく、その大半が中国から輸入されたものである。   By the way, it was common for horsetails to harvest and use fruits that grew naturally in lakes and creeks at the time of fruiting. However, there is a disadvantage that it is difficult and the yield is low, and a reduction policy is being promoted as part of the country's agricultural policy. It is carried out mainly in prefectures and Saga prefectures (see Non-Patent Document 1). Currently, there is little domestic production of hoshi, most of which is imported from China.

特開2007−306895号公報JP 2007-306895 A

社団法人 農山漁村文化協会発行 「月刊 現代農業」 1999年12月号(196頁〜201頁)“Monthly Modern Agriculture” December 1999 issue (pp. 196-201)

ところが、このような田圃でのヒシ栽培は、自生状態のヒシを管理する場合に比して栽培状態の管理が容易で収量アップも期待できるものの、その収穫作業は田圃に入って腰を屈めて一つ一つヒシの株を持上げてヒシの生育状態を確認し、生育の良い物だけを選んで採取するため、作業労力が大きく、非常に疲れるものであった。   However, in this kind of paddy field cultivation, the cultivation state is easier to manage and the yield can be expected to be higher than in the case of managing the native seedlings. Since each strain was picked up one by one to check the growth status of the casters, and only those with good growth were selected and collected, the work effort was large and very tired.

また、ヒシにはアク(灰汁)があり、これが田圃の水に溶け出すと、ヒシの実が黒く変色し、特に表面色が青色の中ヒシとか赤色のオニヒシにあってはその商品価値が下がるため、収穫時期が近づくと、田圃の水を定期的に入れ替えるとか、少流量で水を継続的に流すなどのアク抜きあるいはアクの希釈作業が必要であり、このような水替えは上掲の福岡県とか佐賀県等の水郷と称されるような農業用水が豊富な地域ではさほど問題とはならないが、農業用水の乏しい地域においてはヒシ栽培における最大のネックとなっている。   In addition, there is an ak (ash juice) in the pear, and when it melts in the water of the rice field, the pear fruit turns black, especially in the case of a blue pear with a surface color of blue or red onion. Therefore, when the harvest time approaches, it is necessary to replace the water in the rice field regularly, or to remove the water or dilute the water, such as continuously flowing water at a low flow rate. This is not a problem in areas with abundant agricultural water, such as Fukuoka and Saga prefectures, but it is the biggest bottleneck in Japanese pear cultivation in areas where agricultural water is scarce.

さらに、ヒシは通常一個の種実から凡そ4〜6つのロゼット株(浮き葉が平面状に広がったもの)が成長し、これら各ロゼット株のそれぞれにおいて4〜6個のヒシの実が採れるので、一個の種実からは16〜36個ぐらいヒシの実が収穫できることになるが、この栽培自体が田圃を利用するものの、自然環境下での栽培であるため、ヒシ栽培及び実の収穫は1年に一度とされ、その収量アップには限界があり、栽培者が増えない一因ともなっている。   In addition, the rose usually grows about 4-6 rosette strains (with floating leaves spread flat) from a single seed, and each of these rosette strains can harvest 4-6 seeds. Although 16 to 36 persimmon seeds can be harvested from a single seed, this cultivation itself uses rice fields, but since it is grown in a natural environment, the cultivation of persimmon and the harvest of the fruit are in one year. It is considered once, and there is a limit to increasing the yield, which is one reason that growers do not increase.

一方、このような問題の解決手段としては、上掲特許文献1に示されるような「水耕栽培」が考えられるが、ヒシには、一般的な野菜とは異なり、水草としての特有の生態があることから、一般的な野菜の水耕栽培についての技術・ノウハウをそのままヒシ栽培に転用することは困難である。   On the other hand, as a means for solving such a problem, “hydroponic cultivation” as shown in the above-mentioned Patent Document 1 can be considered. Therefore, it is difficult to divert technology and know-how about general hydroponic cultivation of vegetables to pear cultivation as it is.

そこで本願発明では、ヒシに特有の生態を考慮した上で、栽培用水の確保が困難な地域においても、品質の良好なヒシを、しかも年複数回の栽培によって多量に収穫できるようにしたヒシの栽培装置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, in consideration of the ecology peculiar to the cypress, even in an area where it is difficult to secure water for cultivation, the cypress has a good quality and can be harvested in large quantities by cultivating multiple times a year. It was made for the purpose of providing a cultivation apparatus.

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の発明に係るヒシの栽培装置では、底部に栽培床2が設けられるとともに栽培液3が供給され該栽培液3中においてヒシの育成が行われる育成槽1と、上記栽培液3を貯留する栽培液槽11と、該栽培液槽11内の栽培液3を上記育成槽1との間で循環させる循環ポンプ12と、上記栽培液3の液温調整を行う調温部13と、上記育成槽1において育成中のヒシから上記栽培液3に溶出するアク成分を除去するアク取り部19とを備えて構成したことを特徴としている。   In the cultivation apparatus of a horsetail concerning 1st invention of this application, the cultivation tank 1 with which the cultivation liquid 3 is supplied while the cultivation bed 2 is provided in the bottom, and cultivation of a sheep is performed in this cultivation liquid 3, and the said cultivation liquid 3 A cultivating solution tank 11 that stores the cultivating solution 3, a circulation pump 12 that circulates the cultivating solution 3 in the cultivating solution tank 11, and a temperature control unit 13 that adjusts the temperature of the cultivating solution 3. The growth tank 1 includes an action removing unit 19 that removes the action components eluted from the growing seeds into the cultivation liquid 3.

本願の第2の発明では、上記第1の発明に係るヒシの栽培装置において、上記栽培床2を、土、砂、フェルト、不織布、繊維編成物の何れか、又はこれらを二種類以上組み合わせて構成したことを特徴としている。   In 2nd invention of this application, in the cultivation apparatus of the horsetail which concerns on the said 1st invention, the said cultivation floor 2 is either soil, sand, felt, a nonwoven fabric, a fiber knitted fabric, or these are combined 2 or more types. It is characterized by the construction.

本願の第3の発明では、上記第1又は第2の発明に係るヒシの栽培装置において、上記育成槽1の上側に照明器4を配置し、該照明器4からの照明光を上記育成槽1内の栽培液3の表面側に照射することを特徴としている。   According to a third invention of the present application, an illuminator 4 is disposed on the upper side of the growth tank 1 in the above-described first or second invention, and the illumination light from the illuminator 4 is emitted from the growth tank. It is characterized by irradiating the surface side of the cultivation liquid 3 in 1.

(a)本願の第1の発明に係るヒシの栽培装置によれば、以下のような効果が得られる。   (A) According to the eaves cultivation apparatus according to the first invention of the present application, the following effects are obtained.

(a−1)ヒシは水草ではあるが浮き草ではなく、その根部分が栽培床2に定着していることが必要であるが、この場合、上述のように、栽培液3が供給される育成槽1の底部に栽培床2が設けられているので、ヒシの種実31を上記栽培床2に載置してこれを発芽させた場合、あるいは別の施設で種実31を発芽させた後、この発芽苗を上記栽培床2に移植した場合には、上記種実31あるいは上記発芽苗の胚軸32から延びる主根33、及び該胚軸32から延びる軸茎34、35に生えた土中根36が上記栽培床2に定着し、該主根33及び土中根36からの養分吸収によって軸茎34、35の成長が促進される。   (A-1) Although the castor is an aquatic plant but not a floating grass, it is necessary that its root portion is fixed on the cultivation floor 2. In this case, as described above, the cultivation liquid 3 is supplied. Since the cultivation floor 2 is provided at the bottom of the tank 1, when the seed seeds 31 are placed on the cultivation floor 2 and germinated, or after seed seeds 31 are germinated in another facility, When the germinated seedling is transplanted to the cultivation floor 2, the main root 33 extending from the seed seed 31 or the hypocotyl 32 of the germinated seedling, and the soil root 36 growing on the stems 34 and 35 extending from the hypocotyl 32 are the above. The growth of the stems 34 and 35 is promoted by the nutrient absorption from the main root 33 and the soil root 36 after being fixed on the cultivation floor 2.

また、ヒシの軸茎34、35は、その根部分の上記栽培床2への定着部分から栽培液3の表面までの距離(液深さ)によってその成長長さが変化する生態をもつことから、例えば、上記根部分が上記栽培床2に定着されていないと上記軸茎34、35が必要以上に延びて該軸茎34、35の先端部分での浮き葉の成長及びこの浮き葉が集合して構成されるロゼット株40の成長が遅れ、延いては該ロゼット株40部分での結花及び結実が遅れることになるが、上述のようにヒシの根部分が上記栽培床2に定着していることで、上記軸茎34、35の成長長さが栽培液3の深さに対応した適正な長さとなり、それだけロゼット株40部分での結花及び結実が促進される。   In addition, the stems 34 and 35 of the eagles have an ecology whose growth length varies depending on the distance (fluid depth) from the root fixed part to the cultivation floor 2 to the surface of the cultivation liquid 3. For example, if the root portion is not fixed on the cultivation floor 2, the stems 34 and 35 extend more than necessary, and the growth of floating leaves at the tip portions of the stems 34 and 35 and the floating leaves gather. The growth of the rosette strain 40 constructed as described above is delayed, and eventually the flowering and fruiting in the rosette strain 40 portion are delayed, but the root portion of the castor is fixed on the cultivation floor 2 as described above. As a result, the growth length of the above-mentioned stems 34 and 35 becomes an appropriate length corresponding to the depth of the cultivation liquid 3, and the flowering and fruiting in the rosette strain 40 part are promoted accordingly.

(a−2)上記栽培液3を貯留する栽培液槽11を備えるとともに、該栽培液槽11内の栽培液3を循環ポンプ12によって上記育成槽1との間で循環させるようにしていることから、栽培水の使用量を可及的に抑えた状態で且つヒシに養分を十分に吸収させることができ、その結果、利用可能な栽培水量が比較的少ない地域であってもヒシの栽培を行うことが容易となる。   (A-2) A cultivation liquid tank 11 for storing the cultivation liquid 3 is provided, and the cultivation liquid 3 in the cultivation liquid tank 11 is circulated between the cultivation tank 1 and the circulation pump 12. Therefore, it is possible to absorb the nutrients sufficiently in the state where the amount of cultivation water used is suppressed as much as possible. Easy to do.

(a−3)上記育成槽1において育成されるヒシから上記栽培液3に溶出するアク成分を除去するアク取り部19を備えているので、アクによるヒシの実への悪影響を可及的に抑えて品質の良いヒシの実を得ることができる。   (A-3) Since it has the action removal part 19 which removes the action component eluting to the said cultivation liquid 3 from the tree grown in the said cultivation tank 1, the bad influence to the fruit of a tree as much as possible is made possible. It is possible to obtain good quality seeds by suppressing them.

(a−4)上記栽培液3の液温調整を行う調温部13を備えているので、例えば、自然環境下ではヒシの種実31が冬眠状態となる低液温(例えば、7℃以下)の冬季であっても、上記調温部13での液温調整によって液温を高めて種実31の冬眠状態を解除してこれを発芽させることができ、これによって年複数回の栽培及び収穫が可能となる。因みに、ヒシは夏植物であって20℃程度の液温が最適であることから、上記調温部13は低液温の昇温が主目的となる。   (A-4) Since the temperature control part 13 which adjusts the liquid temperature of the said cultivation liquid 3 is provided, for example, the low liquid temperature (for example, 7 degrees C or less) from which the seed seed 31 of a horse chestnut becomes a hibernation state in a natural environment. Even in the winter season, the liquid temperature can be raised by adjusting the liquid temperature in the temperature control unit 13 to release the hibernating state of the seeds 31 and germinate them. It becomes possible. Incidentally, the castor is a summer plant, and the liquid temperature of about 20 ° C. is optimal. Therefore, the temperature adjustment unit 13 is mainly intended to raise the temperature of the liquid temperature.

(a−5) 以上の(a−1)〜(a−4)の相乗効果として、栽培用水の確保が困難な地域においても、品質の良好なヒシを、しかも年複数回の栽培によって多量に収穫することが可能なヒシの栽培装置を提供することができる。   (A-5) As a synergistic effect of the above (a-1) to (a-4), even in an area where it is difficult to secure water for cultivation, a high quality castor is produced in a large amount by cultivation several times a year. It is possible to provide an easter cultivation device that can be harvested.

(b)本願の第2の発明に係るヒシの栽培装置によれば、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、上記栽培床2を、土、砂、フェルト、不織布、繊維編成物の何れか、又はこれらを二種類以上組み合わせて構成しているので、上記栽培床2を構成する素材の選択が容易となり、その選択によってはヒシの栽培装置の低コスト化とか軽量化等が促進される。また、例えば、フェルト、不織布、繊維編成物を用いる場合には、例えば、土、砂を用いる場合に比して、それぞれの取り扱いが容易となり、延いてはヒシ栽培作業の簡易化も図れる。   (B) According to the eaves cultivation apparatus 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 said cultivation floor 2 is comprised in any one of earth, sand, felt, a nonwoven fabric, a fiber knitted fabric, or these two or more types, it is comprised of the raw material which comprises the said cultivation floor 2 Selection is facilitated, and depending on the selection, cost reduction, weight reduction, and the like of the cultivating apparatus for sheep are promoted. For example, when using felt, a nonwoven fabric, and a fiber knitted fabric, each handling becomes easy compared with the case where soil and sand are used, for example, and a sinew cultivation work can also be simplified.

(c)本願の第3の発明に係るヒシの栽培装置によれば、上記(a)又は(b)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、上記育成槽1の上側に照明器4を配置し、該照明器4からの照明光を上記育成槽1内の栽培液3の表面側に照射するようにしていることから、この照射光によって栽培液3の表面に浮かんだロゼット株40の各浮き葉、及び栽培液3中にある軸茎34、35に生えた水中根37での光合成を促進させることができ、従って、太陽光を用いた栽培のみならず、上記照射光を用いた屋内施設での栽培、あるいはこれら両者の併用による栽培等、その栽培形態の選択の自由度が高くなる。また、ヒシは、野菜等と異なって、気孔は葉の表面側にあることから、この葉の表面側に照明光を照射することで、より効率的に光合成が行われ、ヒシの生育促進が図れる。   (C) According to the eaves cultivation apparatus according to the third invention of the present application, in addition to the effects described in the above (a) or (b), the following specific effects can be obtained. That is, in this invention, the illuminator 4 is disposed on the upper side of the growth tank 1, and the illumination light from the illuminator 4 is irradiated on the surface side of the cultivation liquid 3 in the growth tank 1. The photosynthesis in each floating leaf of the rosette strain 40 floated on the surface of the cultivation liquid 3 by this irradiation light and the underwater roots 37 grown on the stems 34 and 35 in the cultivation liquid 3 can be promoted. In addition to cultivation using sunlight, the degree of freedom in selecting a cultivation form such as cultivation in an indoor facility using the irradiation light or cultivation using both of them is increased. In addition, unlike vegetables etc., since the pores are on the surface side of the leaf, photosynthesis is performed more efficiently by irradiating the surface of the leaf with illumination light, and the growth of the tree is promoted. I can plan.

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。   Hereinafter, the present invention will be specifically described based on preferred embodiments.

A:ヒシの栽培装置Zの構成
図1には、本願発明の実施の形態に係るヒシの栽培装置Zのシステム構成を示しており、同図において符号1は上面が開口した矩形箱状の育成槽である。
A: Configuration of Hoshi Cultivation Device Z FIG. 1 shows the system configuration of a Hishi cultivation device Z according to the embodiment of the present invention. In FIG. It is a tank.

この育成槽1の大きさは、栽培対象のヒシの種類に応じて適宜設定されるものであって、例えば、実の大きいオニビシを栽培する場合には、一つの種実31から4〜6個のロゼット株40ができ、また一つのロゼット株40の平面上の直径寸法が約30cmであり、しかもヒシには隣り合うロゼット株40同士が密接しないと結花しにくい一方、ロゼット株40同士が余り詰み合うとロゼット株40の一部が液面上に迫り出して枯れる恐れがある。これらの点を勘案した結果、平面積が3000cm 〜 5000cm 程度の矩形又は円形の槽が好適と考えられる。尚、この実施形態では、栽培液3の循環性、育成槽1の占有面積の抑制等の観点から、長矩形の平面形状に設定しているが、係る設定に限定されないことは言うまでもない。また、上記育成槽1の素材には何等制約はない。 The size of the growing tank 1 is appropriately set according to the type of the cultivar to be cultivated. For example, when cultivating a large Onibishi, 4 to 6 seeds 31 are cultivated. A rosette strain 40 is formed, and the diameter dimension of one rosette strain 40 on the plane is about 30 cm. Moreover, the rosette strains 40 are clogged too much while the adjacent rosette strains 40 are difficult to be in contact with each other. If they match, a part of the rosette strain 40 may squeeze out on the liquid surface and die. As a result of consideration of these points, the plane area rectangular or circular tank of about 3000 cm 2 ~ 5000 cm 2 is considered to be preferred. In addition, in this embodiment, from a viewpoint of the circulation property of the cultivation liquid 3, suppression of the occupation area of the growth tank 1, etc., it sets to the oblong planar shape, but it cannot be overemphasized that it is not limited to the setting which concerns. Moreover, there is no restriction | limiting in the raw material of the said growth tank 1. FIG.

さらに、この育成槽1の深さは、ヒシに特有の生態、即ち、ロゼット株40から出現した花茎は結花受粉の後、液面下に潜って次第に成長するという生態があり、ロゼット株40の下部を確実に液面下に沈めたまま維持できるだけの水深が必要であって、例えばオニビシを栽培する場合の水深は約25〜35cmとするのが最適である。従って、上記育成槽1の深さ寸法は、上記水深を得られるような寸法(例えば、30〜40cm)に設定される。   Further, the depth of the breeding tank 1 has an ecology peculiar to horse chestnuts, that is, an ecology in which flower stems emerging from the rosette strain 40 gradually grow under the surface of the flower after pollination. A water depth that can be maintained while the lower part is surely submerged below the liquid level is necessary. For example, the water depth when cultivating Onibibishi is about 25 to 35 cm. Therefore, the depth dimension of the said growth tank 1 is set to the dimension (for example, 30-40 cm) which can obtain the said water depth.

上記育成槽1には、給液管21と排液管22及び越流管23が備えられている。上記給液管21には後述の循環ポンプ12によって栽培液槽11から栽培液3が供給される。上記排液管22には、止水弁18が設けられている。さらに、上記越流管23は、上記育成槽1内の栽培液3に深さを一定に保持するものであって、その管端面の高さは、上記水深を確保できるように設定され、さらに必要に応じてその高さ位置を変更調整できる(図示省略)ようになっている。なお、この越流管23の管端面の高さ調整は、ヒシの成長に合わせて栽培過程の何れにおいても最適な水深が得られるようにするためとか、栽培されるヒシの種類の変更に対処するためである。   The growth tank 1 is provided with a liquid supply pipe 21, a drainage pipe 22 and an overflow pipe 23. The cultivation liquid 3 is supplied from the cultivation liquid tank 11 to the liquid supply pipe 21 by a circulation pump 12 described later. The drainage pipe 22 is provided with a water stop valve 18. Further, the overflow pipe 23 is to maintain a constant depth in the culture solution 3 in the growth tank 1, and the height of the pipe end face is set so as to ensure the water depth. The height position can be changed and adjusted as necessary (not shown). It should be noted that the height adjustment of the pipe end face of the overflow pipe 23 is to cope with the change of the type of cultivated eagles so as to obtain an optimum water depth in any cultivation process in accordance with the growth of eagles. It is to do.

また、この実施形態では、後述のように、上記育成槽1を施設内に多段配置し照明光を用いた促成栽培を意図しており、そのため上記育成槽1の上方には照明器4が配置される。   Moreover, in this embodiment, as described later, the above-described growth tank 1 is arranged in a multi-stage in the facility, and forcing cultivation using illumination light is intended. Therefore, an illuminator 4 is arranged above the growth tank 1. Is done.

一方、上記育成槽1には、該育成槽1におけるヒシの栽培状態を管理するための栽培管理部10が付設される。この栽培管理部10は、所定容量をもつ栽培液槽11を備えるとともに、該栽培液槽11の一端側には循環ポンプ12と調温部13を備え且つ上記育成槽1の上記給液管21に接続される栽培液供給路25が接続され、また上記栽培液槽11の他端側にはアク取り部19と濃度センサ20を備え且つ上記育成槽1の排液管22及び越流管23に接続される栽培液帰還路26が接続されている。   On the other hand, the cultivation tank 1 is provided with a cultivation management unit 10 for managing the cultivation state of the bean in the cultivation tank 1. The cultivation management unit 10 includes a cultivation liquid tank 11 having a predetermined capacity, and includes a circulation pump 12 and a temperature control unit 13 on one end side of the cultivation liquid tank 11 and the liquid supply pipe 21 of the cultivation tank 1. A culture solution supply path 25 connected to the cultivating solution tank 11 is connected to the other end side of the cultivating solution tank 11, and a drainage pipe 22 and an overflow pipe 23 of the growth tank 1 are provided. The culture solution return path 26 connected to is connected.

さらに、上記栽培液槽11には、給液弁16を備えた養液供給路27と、給水弁17を備えた給水路28が、それぞれ接続されている。また、上記育成槽1の側面には、温度センサ15が取付けられている。   Furthermore, a nutrient solution supply path 27 provided with a liquid supply valve 16 and a water supply path 28 provided with a water supply valve 17 are connected to the cultivation liquid tank 11, respectively. A temperature sensor 15 is attached to the side surface of the growth tank 1.

そして、上記循環ポンプ12と調温部13と給水弁17及び給水弁17は、次述のコントローラ14によってその作動が制御される。上記コントローラ14は、上記温度センサ15からの液温信号を受けて、上記育成槽1内の栽培液3の液温を予め設定した設定温度(この設定温度は、栽培工程に応じて設定される)となるように温度調整を行う。尚、この温度調整は、栽培液3の昇温作用が主となるもので、例えば、ヒータで構成されるが、必要に応じて降温作用を行うように構成することもできる。   The operations of the circulation pump 12, the temperature control unit 13, the water supply valve 17, and the water supply valve 17 are controlled by the controller 14 described below. The controller 14 receives a liquid temperature signal from the temperature sensor 15 and presets the liquid temperature of the cultivation liquid 3 in the growth tank 1 (this set temperature is set according to the cultivation process). ) Adjust the temperature so that This temperature adjustment is mainly performed by the temperature raising action of the cultivating liquid 3 and is constituted by, for example, a heater, but may be constituted to perform a temperature lowering action as required.

また、上記コントローラ14は、上記濃度センサ20からの濃度信号を受けて、上記栽培液槽11内に貯留される栽培液3の養分濃度を予め設定した設定濃度となるように、上記給液弁16及び給水弁17を適宜作動させて養液Qと水Wを上記栽培液槽11に補給する。   In addition, the controller 14 receives the concentration signal from the concentration sensor 20 and the liquid supply valve so that the nutrient concentration of the cultivation liquid 3 stored in the cultivation liquid tank 11 becomes a preset concentration. The nutrient solution Q and water W are replenished to the culture solution tank 11 by appropriately operating 16 and the water supply valve 17.

一方、上記循環ポンプ12は、上記コントローラ14からの制御信号によって作動制御されるものであって、上記栽培液槽11内の栽培液3を常時上記育成槽1側へ送給して循環させるものであるが、係る作動形態に限定されるものではなく、例えば、所定期間毎に所定時間だけ運転されて上記栽培液槽11内の栽培液3を完結的に上記育成槽1側へ送給するように構成することもできる。   On the other hand, the circulation pump 12 is controlled by a control signal from the controller 14 and constantly feeds and circulates the cultivation liquid 3 in the cultivation liquid tank 11 to the cultivation tank 1 side. However, it is not limited to such an operation mode. For example, it is operated for a predetermined time every predetermined period, and the cultivation liquid 3 in the cultivation liquid tank 11 is completely fed to the growth tank 1 side. It can also be configured as follows.

また、上記アク取り部19は、脱着式の吸着材を内装し、この吸着材に上記育成槽1から帰還する栽培液3を通過させることで該栽培液3に含まれたアク成分を吸着除去して上記栽培液槽11へ戻すものであり、このアク取り部19のアク取り作用によって上記栽培液槽11内の栽培液3はアク成分が可及的に除去された清浄栽培液とされる。   Moreover, the said action removal part 19 carries out adsorption removal of the ac component contained in this cultivation liquid 3 by carrying the cultivation liquid 3 which returns from the said growth tank 1 through the adsorption | suction material inside a desorption type adsorption | suction material. Thus, the cultivation liquid 3 in the cultivation liquid tank 11 is made into a clean cultivation liquid from which the ak components are removed as much as possible. .

尚、この実施形態では上記アク取り部19を吸着材を用いて構成したが、本願発明はこれに限定されるものではなく、要は栽培液3に含まれたアク成分を分離して除去できるものであれば良く、例えば、上記吸着材の内装に代えて、イオン交換膜、浸透膜等を用いることもできるものである。   In addition, in this embodiment, although the said action picking part 19 was comprised using the adsorbent material, this invention is not limited to this, The point can isolate | separate and remove the ax component contained in the cultivation liquid 3. For example, an ion exchange membrane, a permeable membrane or the like can be used instead of the interior of the adsorbent.

B:栽培装置Zの設置
この実施形態では、施設内でのヒシ栽培を目的としており、そのために図2及び図3に示すように、棚部51を上下方向に所定間隔で多段に配置した支持棚50を用意し、この支持棚50の各棚部51のそれぞれの上面側に上記育成槽1を載置する。また、上記支持棚50の各棚部51の下面側にそれぞれ照明器4を下方に向けて設置し、該照明器4からの照明光がその下側に設置された上記育成槽1の上面側を照射するようにしている。
B: Installation of the cultivation apparatus Z In this embodiment, the purpose is for cultivation of castor in the facility. For this purpose, as shown in FIGS. 2 and 3, the shelf 51 is arranged in multiple stages at predetermined intervals in the vertical direction. A shelf 50 is prepared, and the growth tank 1 is placed on the upper surface side of each shelf 51 of the support shelf 50. Moreover, the illuminator 4 is installed on the lower surface side of each shelf 51 of the support shelf 50 so that the illumination light from the illuminator 4 is installed on the lower side thereof. Is irradiated.

また、この場合、図5に示すように、上下方向に多段配置された上記各育成槽1を上記栽培管理部10の栽培液供給路25及び栽培液帰還路26によって並列的に接続し、上記各育成槽1のそれぞれにおける栽培液3の供給形態の均一化を図っている。   Moreover, in this case, as shown in FIG. 5, the growing tanks 1 arranged in multiple stages in the vertical direction are connected in parallel by the cultivation liquid supply path 25 and the cultivation liquid return path 26 of the cultivation management unit 10, and The supply form of the cultivation liquid 3 in each of the growing tanks 1 is made uniform.

尚、図示していないが、上記各育成槽1相互間のヘッド差による栽培液3の供給量の不均一を解消する観点から、上記各育成槽1への上記栽培液供給路25から分岐して上記各育成槽1のそれぞれに至る分岐路に、例えば、オリフィス、流量調整正弁等の調量部材を設け、その開度を上段側の育成槽1から下段側の育成槽1に向かうに伴って絞るとか、上記各分岐路の口径を上段側の育成槽1から下段側の育成槽1に向かうに伴って小さくすることも有効である。   In addition, although not shown in figure, it branches from the said culture solution supply path 25 to each said growth tank 1 from a viewpoint of eliminating the nonuniformity of the supply amount of the culture solution 3 by the head difference between each said growth tank 1. For example, a metering member such as an orifice or a flow rate adjusting valve is provided in each branch passage leading to each of the above-described growth tanks 1 so that the opening degree is directed from the upper growth tank 1 to the lower growth tank 1. It is also effective to squeeze along with it, or to reduce the diameter of each branch path from the upper growth tank 1 toward the lower growth tank 1.

また、上記照明器4の照度あるいは上記育成槽1との間隔等は、上記育成槽1において栽培されるヒシの浮き葉を十分に照射して光合成を促進させ得ると同時に、該浮き葉に熱害を及ぼすことがなく、且つ該育成槽1からのヒシの実の収穫作業に支障を及ぼさないように適宜設定される。なお、上記照明器4の照明具としては、蛍光灯とかLEDランプが適用可能であるが、特にLEDランプを用いた場合にはヒシに対する熱害という問題が殆ど無いため最適である。   Further, the illuminance of the illuminator 4 or the interval between the illuminator 4 and the growth tank 1 can sufficiently irradiate the floating leaves of the cultivated chicks in the growth tank 1 to promote photosynthesis, and at the same time, It is set as appropriate so as not to cause harm and not to hinder the harvesting operation of the seeds from the growth tank 1. As the illuminator of the illuminator 4, a fluorescent lamp or an LED lamp can be applied. However, particularly when an LED lamp is used, it is optimal because there is almost no problem of heat damage to the shadow.

C:栽培装置Zを用いたヒシの栽培
(C−1) ヒシに特有の生態等
先ず、ヒシに特有の生態等について図4を参照して簡単に説明する。
C: Cultivation of Hashi Using Cultivation Device Z (C-1) Ecology Specific to Hashi First, ecology specific to Hashi will be briefly described with reference to FIG.

ヒシは、水底に沈んで冬眠した実(種実)が、水温の上昇(約7℃以上)によって活性化されて発芽する。そして、図4に示すように、種実31から延びた胚軸32の先端から主根33と軸茎34がそれぞれ枝分かれする。   The seeds that have sinked into the bottom of the water and hibernated (seed seeds) are activated by a rise in water temperature (about 7 ° C. or more) and germinate. Then, as shown in FIG. 4, the main root 33 and the stem 34 are branched from the tip of the hypocotyl 32 extending from the seed 31.

上記主根33には、側根といわれるヒゲ状の土中根36が多数生え、この土中根36が土中に潜ってここに根を張ることで、水底に固定されるとともに土中から養分を取り込むことができ、これによって上記軸茎34の安定した成長が促進される。このように上記主根33で水底に固定される点が、ヒシは水草ではあるが浮き草ではない、といわれる所以である。   The main root 33 has a large number of beard-like soil roots 36 called side roots, and the soil roots 36 are submerged in the soil and rooted here, so that they are fixed on the bottom of the water and take in nutrients from the soil. As a result, stable growth of the stem 34 is promoted. The point fixed to the bottom of the water by the main root 33 in this way is that it is said that the castor is aquatic grass but not floating grass.

一方、上記軸茎34は、所定間隔で多数の節を形成しながら成長する茎であって、上記胚軸32に近い節部には、土中根36とシダ状の形体で且つ光合成機能を有する水中根37が生えている。この軸茎34の土中根36も水底に潜って成長する。   On the other hand, the stem 34 is a stem that grows while forming a large number of nodes at a predetermined interval, and the node close to the hypocotyl 32 has a soil-like root 36 and a fern-like shape and has a photosynthetic function. Underwater roots 37 are growing. The soil root 36 of the stem 34 also grows under the water.

また、上記軸茎34は、上記胚軸32から遠くの節になるにつれて土中根36が短くなり、あるいは次第に消滅し、これに代わって水中根37が大いに繁茂した状態となり、次第に水面側に向かって延びていく。さらに、上記軸茎34の成長に伴って、いくつかの節から新たな軸茎35が分岐して成長し、これも次第に水面側に向かって延びていく。   In addition, as the stem 34 becomes a node farther away from the hypocotyl 32, the soil root 36 becomes shorter or gradually disappears, and instead, the underwater root 37 is in a state of great growth and gradually toward the water surface. And extend. Further, along with the growth of the stem 34, a new stem 35 is branched and grown from several nodes, and this also gradually extends toward the water surface.

このように水面側に延びた軸茎34、35の先端部分では、次第に間隔が狭くなった各節から葉柄が成長し、この葉柄の先に浮葉41が形成されこれが次第に平面状に拡大成長する。これら多数の浮葉41が葉柄の先にロゼット状(葉をある点の回りに順次平に並べた形体)に展開してロゼット株40を構成する。   In this way, at the tip portions of the stems 34 and 35 extending to the water surface side, a petiole grows from each node whose space is gradually narrowed, and a floating leaf 41 is formed at the tip of the petiole, which gradually expands and grows in a planar shape. . A large number of these floating leaves 41 are developed in a rosette shape (a form in which leaves are sequentially arranged flatly around a certain point) at the tip of the petiole to constitute a rosette strain 40.

そして、このロゼット株40においては、順次花柄が成長しその先にヒシの花が開花する。この花は一日花で、開花したあと自家受粉し、受粉すると花柄が次第に水中側に曲がって水没し、水中にて結実しこれが成長してヒシの実となる。このヒシの実は、成長して熟すると採取され、食用に、あるいは薬用に供される。なお、採取されなかったヒシの実は、自然に花柄から離脱して落下し、水底において冬眠する。   And in this rosette stock | strain 40, a floral pattern grows up sequentially and a flower of a bean blooms ahead. This flower is a flower of the day, self-pollinated after flowering, and when pollinated, the floral pattern gradually bends to the water side and submerses, and the fruit grows in water and grows to become a fruit of a castor. The seeds are collected as they grow and ripen, and are used for food or medicine. In addition, the fruit of the sunflower that was not collected naturally leaves the flower pattern and falls, and hibernates at the bottom of the water.

(C−2) 栽培方法等
(a) 栽培床2の設置
図2に示すように、上記支持棚50の各棚部51に載置された各育成槽1の底部に上記栽培床2を設ける。この場合、上記栽培床2を土又は砂あるいはこれらを混合したもので構成するときは、この土等を上記育成槽1の底部に5cm〜10cmの厚さに敷詰める。また、上記栽培床2をフェルト、不織布、繊維編成物又はこれらを組み合わせて構成するときにも、これらフェルト、不織布、繊維編成物等を上記育成槽1の底部に5cm〜10cmの厚さに敷詰める。
(C-2) Cultivation method etc. (a) Installation of cultivation floor 2 As shown in FIG. . In this case, when the cultivation floor 2 is composed of soil or sand or a mixture thereof, the soil or the like is laid on the bottom of the growth tank 1 to a thickness of 5 cm to 10 cm. In addition, when the cultivation floor 2 is composed of felt, nonwoven fabric, fiber knitted fabric, or a combination thereof, these felt, nonwoven fabric, fiber knitted fabric, etc. are laid on the bottom of the growth tank 1 in a thickness of 5 cm to 10 cm. pack.

なお、この実施形態においては、上述のように、上記育成槽1の底部の全域に略均一厚さで上記栽培床2を敷詰めるように構成しているが、本願発明は係る構成に限定されるものではなく、上記育成槽1の底部の一部領域のみに上記栽培床2を設けることもできる。この場合、上記「一部領域」とは、発芽した種実31の胚軸32の先端から延びる上記主根33と軸茎34の各節から発生した土中根36、及び該軸茎34からさらに分岐して延びる軸茎35の各節から発生した土中根36を定着させるに必要な大きさの領域である。   In this embodiment, as described above, the cultivation floor 2 is configured to be spread over the entire area of the bottom of the growth tank 1 with a substantially uniform thickness. However, the present invention is limited to such a configuration. However, the cultivation floor 2 can be provided only in a partial region of the bottom of the cultivation tank 1. In this case, the “partial region” further branches from the soil root 36 and the stem 34, which are generated from each node of the main root 33 and the stem 34 extending from the tip of the hypocotyl 32 of the germinated seed 31. This is an area of a size necessary for fixing the soil root 36 generated from each node of the stem 35 extending in the direction.

また、上記育成槽1を施設内に設置するのではなく、例えば、干上げた田圃に設置するような場合には、田圃の土をそのまま上記育成槽1内に投入してこれによって上記栽培床2を構成することもでき、しかも一作毎に、あるいは複数作毎に土を入れ替えることも容易である。   Moreover, when the said growth tank 1 is not installed in a facility, for example, when installing in the dried rice field, the soil of rice field is thrown into the said cultivation tank 1 as it is, and thereby the said cultivation bed 2 can also be configured, and it is also easy to replace the soil for each work or for every plurality of works.

(b) 播種又は苗の定植
上記栽培床2が設けられた上記育成槽1内に、上記栽培液槽11内の栽培液3を導入し、該栽培床2を上記栽培液3中に浸漬させる。この状態で、保管しておいた種実31を上記栽培床2上に載置し(播種)、又は上記種実31を予め発芽させた苗を上記栽培床2上に定植する。なお、上記苗は、例えば、少なくとも7℃以上の温度に保持された別途装置の栽培液3内に上記種実31を浸漬することで行われる。
(B) Planting of seeding or seedlings The cultivation liquid 3 in the cultivation liquid tank 11 is introduced into the growth tank 1 provided with the cultivation floor 2, and the cultivation floor 2 is immersed in the cultivation liquid 3. . In this state, the stored seeds 31 are placed on the cultivation floor 2 (seeding), or seedlings on which the seeds 31 have been germinated in advance are planted on the cultivation floor 2. In addition, the said seedling is performed by immersing the said seed seed 31 in the cultivation liquid 3 of the separate apparatus hold | maintained at the temperature of at least 7 degreeC or more, for example.

また、この播種又は苗の定植時点では、上記育成槽1内の栽培液3の深さを、種実31又は苗を水没保持できる程度に浅くして、該栽培液3の温度保持作用を高めればよい。   Further, at the time of sowing or planting of seedlings, if the depth of the cultivation liquid 3 in the growth tank 1 is made shallow enough to hold the seeds 31 or seedlings submerged, the temperature holding action of the cultivation liquid 3 can be enhanced. Good.

(c) ヒシの育成
播種又は定植後、上記循環ポンプ12を低速で常時運転して上記栽培液3を上記育成槽1に循環させるか、あるいは上記循環ポンプ12を低速で所定時間(所定日数)ごとに運転して上記栽培液3を上記育成槽1に間歇的に循環させて、ヒシの養分吸収を促進し、その生育を図る。
(C) Breeding of seedlings After sowing or planting, the circulating pump 12 is always operated at a low speed to circulate the culture solution 3 to the growing tank 1 or the circulating pump 12 is operated at a low speed for a predetermined time (a predetermined number of days). It drives every time and the said culture solution 3 is intermittently circulated to the said growth tank 1, the nutrient absorption of a horsetail is promoted, and the growth is aimed at.

この場合、上記調温部13によって上記育成槽1内の栽培液3の温度管理を行うとともに、上記濃度センサ20の検出濃度に基づいて上記栽培液3の養分濃度を、水Wと養液Qの供給制御によって、管理する。   In this case, while controlling the temperature of the cultivation liquid 3 in the said growth tank 1 by the said temperature control part 13, based on the detected density | concentration of the said density | concentration sensor 20, the nutrient concentration of the said cultivation liquid 3 is made into the water W and the nutrient solution Q. It is managed by supply control.

種実31から発芽した胚軸32、あるいは定植された苗の胚軸32から軸茎34、35が延びて、ヒシが生長すると、この成長状態、即ち、軸茎34、35の長さの変化、枝別れ繁茂の状態に応じて、栽培液3の深さを調整する。上記軸茎34、35が延びて液面に達するようになると、それぞれの先端寄り部分に葉茎が順次発生し、これら多数の葉がロゼット状に茂ってロゼット株40となる。このロゼット株40はさらに成長して大きく拡大するので、このロゼット株40同士が過度に詰み合わないように、また液面から浮上しないように管理することが必要となる。   When the stems 34, 35 extend from the hypocotyl 32 germinated from the seed 31 or the hypocotyl 32 of the planted seedling, and the bean grows, this growth state, that is, the change in the length of the stems 34, 35, The depth of the cultivation liquid 3 is adjusted according to the state of branching and growing. When the stems 34 and 35 extend to reach the liquid level, leaf stems are sequentially generated at the end portions of the stems, and a large number of these leaves grow in a rosette shape to form a rosette strain 40. Since the rosette strain 40 is further grown and greatly expanded, it is necessary to manage the rosette strain 40 so that the rosette strains 40 are not excessively clogged with each other and do not float from the liquid surface.

多数のロゼット株40同士が適度に詰み合う程度に成長すると、各ロゼット株40においては花柄が順次成長し、液面上に突出した花柄の先端に花をつける。この花が自家受粉すると、花柄は次第に曲がり始めて栽培液3に没し、液中で結実してヒシの実となって次第に成長する。従って、この花柄及びヒシの実が栽培液3から液面上に飛び出ないように管理することが必要である。   When a large number of rosette strains 40 grow to an appropriate degree, floral patterns grow sequentially in each rosette strain 40, and flowers are attached to the tips of the floral patterns protruding above the liquid surface. When this flower is self-pollinated, the floral pattern gradually begins to bend and is submerged in the cultivation liquid 3, and the fruit pattern grows in the liquid to become a fruit of a pear. Therefore, it is necessary to manage so that the flower pattern and the fruit of the caster do not jump out from the cultivation liquid 3 onto the liquid surface.

また、ヒシの実が成長する段階では、その茎とか葉からの栽培液3へのアクの溶出が多くなるため、特にアク取り部19が十分に機能しているか同かを監視し、アクによるヒシの実の変色を防止することが重要となる。   Further, at the stage where the seeds of the cypress grow, the amount of squeezed eluate from the stems or leaves into the cultivation liquid 3 increases. It is important to prevent the discoloration of the seeds.

成長したヒシの実は、そのまま放置すれば支弁に花柄から離脱して栽培床2側に沈下するが、この沈下前に実の充実を確認して採取する。このヒシの実の充実状態、即ち、採取時期の確認は、視覚では実の左右両側から延びていたツノ部分の先が丸くなったことで確認でき、触覚では実の左右のツナ部分同士を折り曲げるように詰まんで、折り曲げが困難と思われるときには採取時期と判断することができる。なお、実の採取は、各実の成長度合いに応じて、段階的に数回行われる。また、採取された実のうち、充実した実を次回の栽培における種実として保存する。   The grown cypress fruit leaves the flower pattern as a branch valve and sinks to the cultivation floor 2 side if it is left as it is, but it is collected after confirming the fruit fullness before this sinking. The confirmation of the fruit's fullness, that is, the sampling time, can be confirmed by the fact that the tip of the horn part extending from the left and right sides of the fruit is rounded visually, and the right and left tuna parts are bent by touch. When it seems to be clogged and difficult to bend, it can be determined that it is time for sampling. In addition, the actual collection is performed several times step by step according to the actual growth degree. In addition, among the collected fruits, the enriched fruits are stored as seed fruits in the next cultivation.

(d) 実の採取後の作業
実の採取が終われば、通常ならば、残った茎とか葉を育成槽1から取り除いて廃棄し、上記育成槽1を次回の栽培に備えて清掃等を行う。
(D) Work after harvesting After the harvesting is finished, usually, the remaining stems and leaves are removed from the growing tank 1 and discarded, and the growing tank 1 is cleaned for the next cultivation. .

しかし、現に行われている田圃でのヒシ栽培では実を採取した後、耕運機で残った茎とか葉を土中にすき込むことで、新たに肥料を施すことなく次回のヒシ栽培を行っていること、及びヒシの実がもつ有効成分は、少なからずヒシの葉及び茎類ももつことが知られていること、等から、実を採取した後、残った葉を採取するとともに、さらに残った茎類も採取してこれを有効に利用する。   However, in the actual rice paddy cultivation in the field, after harvesting the fruit, the next time it is cultivated without adding new fertilizer, by squeezing the stems and leaves left in the cultivator into the soil. It is known that the active ingredients of the cypress fruit also have not only the leaves and stems of the cypress, but after collecting the fruit, the remaining leaf was collected and further remained. Stems are also collected and used effectively.

例えば、採取した葉は、乾燥させて粉砕して、あるいは生のまま成分を抽出して、飲用材とか薬用材として用いることができる。また、茎類は、これを乾燥して粉砕して、例えば、菜園用、観葉植物用の肥料として用いることができる。   For example, the collected leaves can be dried and pulverized, or raw components can be extracted and used as drinking materials or medicinal materials. In addition, the stems can be dried and pulverized, and used as fertilizers for vegetable gardens and foliage plants, for example.

なお、採取された実は、殻をとって中身を食用材あるいは薬用材として用いられるのが通例である。   In general, the harvested fruits are shelled and the contents are used as edible materials or medicinal materials.
