Description
本発明は、施設園芸における栽培方法および培地の製造技術に関し、特に簡易施設を用いて種々の植物（農作物）を栽培できる隔離床栽培施設および、その施設を構成する隔離床栽培施設用ユニットに関する。 The present invention relates to a cultivation method and medium production technology in facility horticulture, and more particularly to an isolated floor cultivation facility that can grow various plants (agricultural crops) using a simple facility, and a unit for an isolated floor cultivation facility that constitutes the facility.
従来の栽培方法、または圃場の土壌に定植する作物生産は、周辺地下水位の変動や排水不良等の土壌条件により（１）潅排水制御が困難となり作物品質を低下させ、（２）土壌病害の発生や土壌中の常在菌の制御が困難であることから大幅な減収を引き起こすか、或いは連作障害の回避のため多量の薬剤投入が必要になる。また、このような連作障害が発生した場合には、（３）肥料の効用が小さく、塩類の集積が生ずるなどの問題がある。 Conventional cultivation methods or crop production to be planted in the soil of the field can cause (1) difficult to control irrigation due to soil conditions such as changes in the surrounding groundwater level and poor drainage, resulting in poor crop quality, and (2) Since it is difficult to control the occurrence and the resident bacteria in the soil, it causes a significant decrease in sales, or a large amount of drug is required to avoid continuous cropping disorders. Moreover, when such a continuous cropping failure occurs, there are problems such as (3) the effect of fertilizer is small and accumulation of salts occurs.
これらの問題を解決するため、コンクリートパネル、ＦＲＰ、ポリエチレン、発泡スチロール等で構成した栽培容器により地床から隔離する栽培方法である隔離床栽培（バッグカルチャー等）または養液栽培が取り入れられている。 In order to solve these problems, isolated floor cultivation (bag culture or the like) or hydroponics, which is a cultivation method for isolating from the ground with a cultivation container composed of concrete panels, FRP, polyethylene, polystyrene foam, and the like, has been introduced.
例えば、特許文献１（特開２００７−２３６２９４号公報）では、底面部とその両側の側面部とを一体形成した適宜深さと長さを有するＵ字状の本体を形成し、本体の長手方向に開放された両端を互いに連接して２以上の本体を順次連接するものであって、本体の一方の端部に排出孔を形成し、もう一方の端部であって前記排出孔より低い位置に供給孔を形成し、さらに本体には隣接する本体の排出孔を遮蔽する遮蔽部を形成した隔離床栽培用プランターが提案されている。 For example, in Patent Document 1 (Japanese Patent Laid-Open No. 2007-236294), a U-shaped main body having an appropriate depth and length is formed by integrally forming a bottom surface portion and side surface portions on both sides thereof, and is formed in the longitudinal direction of the main body. The open ends are connected to each other so that two or more main bodies are connected in order, and a discharge hole is formed at one end of the main body, and the other end is at a position lower than the discharge hole. A planter for isolated floor cultivation has been proposed in which a supply hole is formed and a shielding part for shielding a discharge hole of an adjacent body is formed on the body.
また特許文献２（特開２００９−２４７３０３号公報）では、液肥である培養液を入れる養液タンクと栽培ベッドとの間を循環させる養液栽培システムであって、前記養液タンク内の培養液を除菌浄化ユニットで除菌浄化し、この除菌浄化ユニットは、前記培養液に紫外線を照射する紫外線照射機能と、紫外線が照射されない部分を含む前記培養液全体にオゾンを供給するオゾン供給機能と、オゾンよりも強い除菌能力と有機物の分解能力とを有する光触媒を前記培養液に作用させる光触媒作用機能とを有するユニットである養液栽培システムが提案されている。 Moreover, in patent document 2 (Unexamined-Japanese-Patent No. 2009-247303), it is a nutrient solution cultivation system which circulates between the nutrient solution tank which puts the culture solution which is liquid fertilizer, and a cultivation bed, Comprising: Culture solution in the said nutrient solution tank The sterilizing and purifying unit sterilizes and purifies the sterilizing and purifying unit, and the sterilizing and purifying unit includes an ultraviolet irradiation function for irradiating the culture solution with ultraviolet rays, and an ozone supply function for supplying ozone to the entire culture solution including a portion not irradiated with ultraviolet rays. And a hydroponic system that is a unit having a photocatalytic function for allowing a photocatalyst having a sterilizing ability stronger than ozone and a decomposition ability of organic matter to act on the culture solution has been proposed.
しかしながら、このような栽培方法では、設置費用が高価であり、少量土壌の管理が難しいなど栽培に伴う技術や労力が必要である。またバッグカルチャー（袋栽培）による栽培方法でも、袋内環境の維持に高度な管理技術が必要となること、また耐候性や設置上の問題があり広範囲な普及に至っていない。 However, such cultivation methods require techniques and labor associated with cultivation, such as high installation costs and difficulty in managing a small amount of soil. Also, the cultivation method by bag culture (bag cultivation) requires advanced management technology to maintain the environment inside the bag, and has not been widely spread due to weather resistance and installation problems.
上記のとおり、従来から提供されている隔離床栽培や養液栽培は、それを設置する際の設備費用が高額であり、また一旦設置した場合には、その撤去が困難となっていた。
そこで本発明では、簡易な構成であって、設置が容易で且つ低コストで設置することができる隔離床栽培施設および、その施設を構成する隔離床栽培施設用ユニットを提供することを第一の課題とする。
As described above, the isolation floor cultivation and the hydroponics that have been conventionally provided have a high facility cost for installing it, and once installed, it has been difficult to remove.
Therefore, the first aspect of the present invention is to provide an isolated floor cultivation facility that has a simple configuration, can be installed easily and at low cost, and a unit for an isolated floor cultivation facility that constitutes the facility. Let it be an issue.
また、バッグカルチャの様に、培地を織布、不織布、シートで包み込み形状を維持する方法では、培地が自立する形状のためバッグは自重に耐える強度が必要となり、更に耐候性、虫害への抵抗性を有する必要がある。
依って本発明では、バッグカルチャにおける容器の様に自立するものではなく、耐候性、虫害への抵抗性を改善した隔離床栽培施設および、その施設を構成する隔離床栽培施設用ユニットを提供することを第二の課題とする。
In addition, the method of wrapping the culture medium with woven fabric, non-woven fabric, and sheet like the bag culture requires the bag to be strong enough to withstand its own weight due to the self-supporting shape of the culture medium, as well as weather resistance and insect resistance. It is necessary to have sex.
Therefore, the present invention provides an isolated floor cultivation facility with improved weather resistance and resistance to insect damage, and a unit for an isolated floor cultivation facility constituting the facility, which is not self-supporting like a container in a bag culture. This is the second issue.
また圃場として、たとえば水田を転用する場合には、耕盤の破壊を避けるため恒久的な剛性を持つ設備の設置は困難であり、かつ恒久的設備を設置した場合も原状回復までを考えた場合に総合的な費用負担は極めて大きいものとなる。
そこで本発明では、耕盤の破壊を避けながらも、更に撤去後における原状回復を極めて容易に行うことのできる隔離床栽培施設および、その施設を構成する隔離床栽培施設用ユニットを提供することを第三の課題とする。
In addition, when diverting paddy fields, for example, it is difficult to install permanent rigid equipment in order to avoid damaging the cultivator, and even when permanent equipment is installed, it is necessary to restore the original condition. In addition, the total cost burden is extremely large.
Accordingly, the present invention provides an isolated floor cultivation facility that can very easily recover the original state after removal while avoiding destruction of the tiller, and an isolated floor cultivation facility unit that constitutes the facility. This is the third issue.
また、設置される形状を正確に作ろうとした場合、長手方向の平行性や適度な傾斜をつけることが必要になるが、設備を設置する土壌は、通常、土壌の含水率の相違により団粒性や粘性が異なることから、平滑乃至は水平な形状が取りにくいのが実情である。
そこで本発明では、設置する隔離床栽培設備の底面を平坦にし、適度な傾斜を設定することのできる隔離床栽培施設および、その施設を構成する隔離床栽培施設用ユニットを提供することを第四の課題とする。
In addition, when trying to make the shape to be installed accurately, it is necessary to provide parallelism in the longitudinal direction and appropriate inclination, but the soil where the equipment is installed is usually aggregated due to the difference in moisture content of the soil. Actually, it is difficult to obtain a smooth or horizontal shape because of differences in properties and viscosity.
Therefore, in the present invention, a fourth aspect of the present invention is to provide an isolation floor cultivation facility that can flatten the bottom surface of the isolation floor cultivation equipment to be installed and set an appropriate inclination, and a unit for the isolation floor cultivation facility that constitutes the facility. It is an issue.
また、土壌を一定の形状に整えて、これにシートを敷設して隔離床栽培設備とした場合であっても、小動物の侵入や植物の根の貫入によりシートが破損することが考えられる。
そこで本発明では、土壌に設置しながらも、このような小動物の侵入や植物の根の貫入によりシートの破損を阻止することのできる隔離床栽培施設および、その施設を構成する隔離床栽培施設用ユニットを提供することを第五の課題とする。
Moreover, even when the soil is arranged in a certain shape and a sheet is laid on the soil for cultivation on an isolated floor, the sheet may be damaged due to the invasion of small animals or the penetration of plant roots.
Therefore, in the present invention, an isolated floor cultivation facility capable of preventing sheet breakage by intrusion of such small animals and penetration of plant roots while being installed in soil, and an isolated floor cultivation facility constituting the facility. The fifth task is to provide units.
そしてシートによって培地を隔離した隔離床栽培設備を土壌に設置した場合には、周辺の地下水位の変化から土壌中に保持された水分が湧出する等により、土壌とシートの間の密着性が失われ、シートに物理的負担がかかることも考えられる。
そこで本発明では、シートによって培地を隔離した隔離床栽培設備において、不要な水分を適切な方法で排出することのできる隔離床栽培施設および、その施設を構成する隔離床栽培施設用ユニットを提供することを第六の課題とする。
When an isolated floor cultivation facility that isolates the culture medium with a sheet is installed in the soil, the adhesion between the soil and the sheet is lost due to, for example, the water retained in the soil from the change in the surrounding groundwater level. It is also possible that a physical burden is placed on the sheet.
Accordingly, the present invention provides an isolated floor cultivation facility capable of discharging unnecessary moisture by an appropriate method in an isolated floor cultivation facility in which a culture medium is isolated by a sheet, and a unit for an isolated floor cultivation facility constituting the facility. This is the sixth issue.
上記課題の少なくとも何れかを解決するべく、本発明では培地を周辺土壌からシート等により隔離して栽培する施設、より具体的には圃場面を一定の容積を持つ形状に整えた植物栽培の培地を支持するための部材（ユニット）を使用した隔離床栽培施設を提供するものである。 In order to solve at least one of the above-mentioned problems, in the present invention, a plant cultivation medium in which the culture medium is isolated from the surrounding soil by a sheet or the like, and more specifically, the plant scene is arranged in a shape having a certain volume. The isolation floor cultivation facility which uses the member (unit) for supporting this is provided.
即ち本発明では、シートによって培地を土壌から隔離した隔離床栽培施設を構成するための隔離床栽培施設用ユニットであって、当該隔離床栽培施設用ユニットは、土壌から区画された培地の底面を整形する底面構成部材と、土壌から区画された培地の側面を整形する法面構成部材とを含んで構成されており、当該底面構成部材は、設置時において高さ方向に貫通する複数のセルを備えて形成されている隔離床栽培施設用ユニットを提供する。 That is, in the present invention, a unit for an isolated floor cultivation facility for constituting an isolated floor cultivation facility in which the medium is isolated from the soil by the sheet, the unit for the isolated floor cultivation facility includes a bottom surface of the medium partitioned from the soil. The bottom surface constituent member is configured to include a slope surface constituent member that shapes the side surface of the medium partitioned from the soil, and the bottom surface constituent member includes a plurality of cells penetrating in the height direction at the time of installation. A unit for an isolated floor cultivation facility is provided.
かかる隔離床栽培施設用ユニットを使用した隔離床栽培施設では、その培地の底面が、高さ方向に貫通する複数のセルを具備する底面構成部材により形成される。そしてこの底面構成部材のセルに土壌を充填することにより、当該培地の底面は底面構成部材により水平の高さが規制され、平坦に形作ることができる。 In an isolated floor cultivation facility using such a unit for an isolated floor cultivation facility, the bottom surface of the culture medium is formed by a bottom surface constituent member having a plurality of cells penetrating in the height direction. And by filling the cell of this bottom surface component member with soil, the horizontal height of the bottom surface of the culture medium is regulated by the bottom surface component member and can be formed flat.
よって、この底面構成部材は底面を確定するために一定の硬さを有することが望ましい。例えば木材、金属、樹脂および加工紙等から選択された帯状部材を、当該帯状部材の幅が底面構成部材の高さの向きになるように組み合わせて形成することができる。例えば、当該帯状部材を格子状に組み合わせたり、帯状部材を波状に湾曲させて平行に配置し、隣り合う帯状部材の湾曲した曲折部同士を貼り合わせるなどによって形成することができる。 Therefore, it is desirable that this bottom surface component member has a certain hardness in order to determine the bottom surface. For example, a band-shaped member selected from wood, metal, resin, processed paper, and the like can be formed in combination so that the width of the band-shaped member is in the direction of the height of the bottom surface constituting member. For example, it can be formed by combining the band-like members in a lattice pattern, arranging the band-like members in a wavy shape in parallel, and bonding the bent portions of the adjacent band-like members together.
また、上記の隔離床栽培施設用ユニットにおいて、法面構成部材は、上記底面構成部材と同じように、帯状部材を格子状に組み合わせたり、帯状部材を波状に湾曲させて平行に配置し、隣り合う帯状部材の湾曲した曲折部同士を貼り合わせた物を使用できるが、その他にも帯状又は板状に形成された平面部と、当該平面部の何れかの面に、当該平面部の厚さ方向外側に向かって突起する壁状部とからなり、当該壁状部は、設置時において土砂を収容する領域部を形成するように構成したものを使用することができる。 Further, in the unit for an isolated floor cultivation facility, the slope constituent member is arranged in parallel by combining the strip-like members in a lattice pattern or by curving the strip-like members in a wavy manner, like the bottom-surface constituent member. Although the thing which bonded the curved bending part of the belt-like member which fits can be used, the thickness of the plane part on the surface of the plane part formed in the shape of a band or a plate in addition, and the plane part concerned A wall-shaped portion projecting toward the outside in the direction can be used, and the wall-shaped portion can be configured to form an area portion for storing earth and sand at the time of installation.
かかる法面構成部材を含む隔離床栽培施設用ユニットを使用すれば、培地の側面が当該法面構成部材によって整形されることから、風化や雨水などにより培地の側壁が崩れるといったおそれを無くすことができる。 If a unit for an isolated floor cultivation facility including such a slope component is used, the side surface of the medium is shaped by the slope component, thereby eliminating the risk that the side wall of the medium will be destroyed by weathering or rainwater. it can.
特に、平面部と壁状部とで構成した法面構成部材では、平面部を用いて形成されることから、培地に対するネズミや蛇などの動物の侵入、あるいは植物の根の侵入を阻止することができる。これにより、当該培地と土壌との境界に防水シートを張って設けた場合であっても、この防水シートに孔をあけられたり、破られたりするおそれを無くすことができる。更に、この平面部の何れかの面には、平面部の厚さ方向外側に向かって突起する壁状部が形成されていることから、この壁状部が形成する領域部で、当該隔離床栽培施設を設置する土壌の土砂を保持することにより、壁面（法面）が崩れ落ちるなどの問題を無くすことができる。 In particular, in a slope component composed of a flat part and a wall-like part, since it is formed using the flat part, it prevents the invasion of animals, such as rats and snakes, or the roots of plants into the culture medium. Can do. Thereby, even if it is a case where a waterproof sheet is stretched and provided at the boundary between the culture medium and the soil, it is possible to eliminate the possibility that the waterproof sheet will be perforated or broken. Furthermore, since a wall-like part protruding toward the outside in the thickness direction of the flat part is formed on any surface of the flat part, the isolation floor is formed in the region part formed by the wall-like part. By holding the earth and sand of the soil where the cultivation facility is installed, problems such as collapse of the wall surface (slope) can be eliminated.
また、上記培地が土壌を凹溝状に掘削した領域内に形成してある場合には、隔離床栽培施設用ユニットは、更に凹状に掘削した培地の底面の角部分であって、且つ法面よりも深い位置に埋設する帯状の法面底保持部材を伴うことができる。この法面底保持部材は、長尺であって幅方向に曲折させて形成し、法面を底側から保持するものとして形成することができる。特にこの法面底保持部材は、長さ方向に交差する向きの縦断面形状が千鳥状となるように曲折させて形成することが望ましい。 In addition, when the medium is formed in a region where the soil is excavated in a groove shape, the unit for isolated floor cultivation facility is a corner portion of the bottom surface of the medium further excavated in a concave shape, and is a slope. A band-shaped slope bottom holding member embedded at a deeper position can be accompanied. The slope bottom holding member is long and bent in the width direction, and can be formed to hold the slope from the bottom side. In particular, it is desirable that the sloped surface holding member is formed by bending so that the longitudinal cross-sectional shape in the direction intersecting the length direction becomes a staggered shape.
また、上記培地が土壌を凹溝状に掘削した領域内に形成してある場合には、隔離床栽培施設用ユニットは、更に長さ方向に直行する向きの断面形状が大凡「コ」字状に形成された畝外保持部材を伴うことができる。培地を凹溝状に掘削した領域内に形成するた場合、この培地内に雨水などが流れ込むことのないように、当該培地の外側を、他の部分よりも高く形成するのが望ましい。その際、畝状に高く形成した部分が風や雨などにより崩れることのないように形成するのが望ましい。そこで、この畝状に高く形成した部分の外側の面に、断面形状が大凡「コ」字状に形成された畝外保持部材を埋め込み、当該畝状に形成した部分が風や雨などで崩れ落ちることがないように形成することが望ましい。 In addition, when the culture medium is formed in a region where the soil is excavated in the shape of a ditch, the unit for the isolated floor cultivation facility has a generally “U” -shaped cross section in a direction perpendicular to the length direction. It can be accompanied by an outer retaining member formed on the heel. When the medium is formed in a region excavated in the shape of a groove, it is desirable to form the outside of the medium higher than the other parts so that rainwater or the like does not flow into the medium. At this time, it is desirable to form a portion that is formed in a bowl shape so as not to collapse due to wind or rain. Therefore, an outside retaining member having a cross-sectional shape formed in a roughly “U” shape is embedded in the outer surface of the portion formed in a bowl shape, and the portion formed in the bowl shape collapses due to wind or rain. It is desirable to form so as not to occur.
そして本発明では、前記課題の少なくとも何れかを解決するために、上記の隔離床栽培施設用ユニットを用いて形成した隔離床栽培施設を提供する。 And in this invention, in order to solve at least any one of the said subject, the isolation floor cultivation facility formed using said unit for isolation floor cultivation facilities is provided.
即ち、シートによって培地を土壌から隔離した隔離床栽培施設であって、土壌を凹状に整形して形成した溝の底面と法面には、上記本発明に係る隔離床栽培施設用ユニットが設置されており、当該隔離床栽培施設用ユニットの上には、防水シートが張設され、前記溝の長さ方向端部には、当該溝内に貯留した液体を排出する排出手段が設けられている隔離床栽培施設である。 That is, the isolated floor cultivation facility in which the medium is isolated from the soil by the sheet, and the unit for the isolated floor cultivation facility according to the present invention is installed on the bottom and the slope of the groove formed by shaping the soil into a concave shape. A waterproof sheet is stretched over the isolated floor cultivation facility unit, and a discharge means for discharging the liquid stored in the groove is provided at the end in the longitudinal direction of the groove. This is an isolated floor cultivation facility.
かかる隔離床栽培施設においては、本発明の底面構成部材により長さ方向にわたって凹凸のない平坦なものとする事ができる。また、この隔離床栽培施設における培地の底面は、長手方向にわたる平行性や適度な傾斜をつけることができる。また上記の法面構成部材を使用している事から、法面を整形することができると共に、風化や雨などによる崩落を阻止し、更に鼠や蛇といった動物や植物の根により防水シートが破られるといった問題を解消することができる。 In such an isolated floor cultivation facility, the bottom constituent member of the present invention can be flat without unevenness in the length direction. In addition, the bottom surface of the culture medium in this isolated floor cultivation facility can be given parallelism and a moderate inclination over the longitudinal direction. In addition, since the above-mentioned slope component is used, the slope can be shaped, it can be prevented from collapsing due to weathering or rain, and the waterproof sheet can be broken by the roots of animals and plants such as corals and snakes. Can be solved.
そして、かかる隔離床栽培施設においては、底面構成部材の下又は間に、土中の水分を排出するためのパイプを設置することもできる。 And in this isolation floor cultivation facility, the pipe for discharging | emitting the moisture in soil can also be installed under or between bottom face structural members.
即ち防水シートによって培地を土壌から隔離した隔離床栽培設備では、周辺の地下水位の変化から土壌中に保持された水分が湧出する等により、土壌とシートの間の密着性が失われ、シートに物理的負担がかかることも考えられる。そこでこのような地下水などの不要な水分をパイプにより排出することで、土壌とシートの間の密着性を恒久的に保持するものである。 In other words, in the isolated floor cultivation facility in which the culture medium is isolated from the soil by the waterproof sheet, the adhesiveness between the soil and the sheet is lost due to, for example, the water retained in the soil from the change in the surrounding groundwater level. It may be a physical burden. Therefore, unnecessary moisture such as groundwater is discharged through a pipe to permanently maintain the adhesion between the soil and the sheet.
そして上記本発明によれば、圃場の水平面より下に育成用の培地を形成するための枠組みを、隔離床栽培施設用ユニットを使用して形成し、培地の下に該枠組みよりも広い幅で地下水の滲み揚がりを防止するシート（以下、防水シートという）を敷き、該防水シートの外側には地下水の余剰な水分を速やかに圃場外に排水するための機構（以下、排水機構という）を設け、潅水、施肥及び通気兼用のパイプ又はチューブを防水シート内側の培地内に埋設した隔離床栽培施設と、かかる隔離床栽培施設による植物の栽培方法を提供することができる。 According to the present invention, the frame for forming the growth medium below the horizontal plane of the field is formed using the unit for the isolated floor cultivation facility, and has a wider width under the medium than the frame. A sheet (hereinafter referred to as a waterproof sheet) that prevents the groundwater from spreading is provided, and a mechanism (hereinafter referred to as a drainage mechanism) for quickly draining excess water from the groundwater to the outside of the field is provided outside the waterproof sheet. An isolation floor cultivation facility in which pipes or tubes for irrigation, fertilization and aeration are embedded in a medium inside a waterproof sheet, and a method for cultivating a plant by the isolation floor cultivation facility can be provided.
かかる隔離床栽培施設と植物の栽培方法によれば、一定の形状に成型された隔離床栽培施設用ユニットの各構成部材（即ち、底面構成部材や法面構成部材など）を土壌中に埋設し、積層されたシートに加わる土壌の内部圧力をもって一定の形状が保持されるところを枠組みとして利用しながら、長手方向全面に展開して動物や昆虫の侵入を防止し、また不要な植物の根の貫入を妨ぐことができる。 According to the isolated floor cultivation facility and the plant cultivation method, each component member of the isolated floor cultivation facility unit (that is, a bottom component member, a slope component member, etc.) molded into a fixed shape is embedded in the soil. Using a place where a certain shape is maintained with the internal pressure of the soil applied to the laminated sheets as a framework, it spreads throughout the longitudinal direction to prevent the invasion of animals and insects, and also prevents unwanted plant roots It can prevent penetration.
かかる隔離床栽培施設を構成する隔離床栽培施設用ユニットの各構成部材（即ち、底面構成部材や法面構成部材など）は硬質のシート状部材を使用して形成することができ、これは適宜な空孔を持ち、硬質シートの両側の水分の通過を阻害しないように形成するのが望ましい。その結果、隔離床栽培施設用ユニットの各構成部材（即ち、底面構成部材や法面構成部材など）の両側で土壌の含水比に大きな差異を生じないため空隙が生じ難く、また土壌内の圧力変化が少なく、隔離床栽培施設用ユニットの各構成部材（即ち、底面構成部材や法面構成部材など）の位置変化を小さくすることが出来る簡易養液栽培施設を構築することができる。 Each component (that is, a bottom component, a slope component, etc.) of the unit for an isolation floor cultivation facility that constitutes such an isolation floor cultivation facility can be formed using a hard sheet-like member. It is desirable to form the hole so that it does not impede the passage of moisture on both sides of the hard sheet. As a result, since there is no significant difference in the moisture content of the soil on both sides of each component of the unit for isolated floor cultivation facilities (ie, bottom component, slope component, etc.), it is difficult for voids to occur and the pressure in the soil It is possible to construct a simple hydroponic cultivation facility that is small in change and that can reduce the change in position of each component member (ie, bottom component member, slope component member, etc.) of the unit for an isolated floor cultivation facility.
また埋設する隔離床栽培施設用ユニットの各構成部材（即ち、底面構成部材や法面構成部材など）は、断面形状の水平方向に摩擦力が働くことから、各部材における接合部や素材の破断、変形の無い範囲で垂直荷重に抵抗し成形された形状を維持することが出来る簡易養液栽培施設を構築することができる。 In addition, each component of the unit for the isolated floor cultivation facility to be embedded (that is, the bottom component, the slope component, etc.) has a frictional force in the horizontal direction of the cross-sectional shape. In addition, it is possible to construct a simple hydroponic cultivation facility that can resist a vertical load and maintain a molded shape without deformation.
また隔離床栽培施設用ユニットの各構成部材（即ち、底面構成部材や法面構成部材など）は、一定の形状に成型され、その間に土壌が充填されるため、粒径、粘性に関わらず、壁面や底面などの厚さ方向の設定は、各構成部材における断面の上端の位置で概ね設定され、または均した際の水平面が確保される簡易養液栽培施設が実現する。 In addition, each component of the unit for isolated floor cultivation facilities (that is, a bottom component, a slope component, etc.) is molded into a certain shape and filled with soil during that time, regardless of particle size, viscosity, The setting in the thickness direction of the wall surface or the bottom surface is generally set at the position of the upper end of the cross section of each component member, or a simple hydroponic cultivation facility that ensures a horizontal surface when leveling is realized.
また土壌中に埋設される隔離床栽培施設用ユニットの構成部材は十分な強度を有することから、小動物や昆虫の侵入、あるいは植物の根の貫入を防止し、土盛りの形状を長期に維持できる簡易養液栽培施設が実現する。 In addition, the components of the unit for isolated floor cultivation facilities that are buried in the soil have sufficient strength, so that the invasion of small animals and insects or the penetration of plant roots can be prevented, and the shape of the pile can be maintained for a long time. Hydroponic cultivation facility is realized.
そして埋設される隔離床栽培施設用ユニットの各構成部材には、周辺土壌を充填し、さらに土壌表面に不透水性のシートにより被覆される構成のため、下部からの水分の蒸散を抑制し土壌の粘性が維持できる簡易養液栽培施設が実現する。 And each constituent member of the unit for an isolated floor cultivation facility to be buried is filled with surrounding soil and further covered with an impervious sheet on the soil surface, so that the transpiration of moisture from the lower part is suppressed. A simple hydroponic cultivation facility that can maintain the viscosity of is realized.

It can comprise using the water supply pump etc. for feeding the adjusted nutrient solution in the nutrient solution adjusting tank to the nutrient solution water supply pipe 6. However, this nutrient solution adjusting tub can be configured to be detachable, and can be used by bringing a jar prepared with the solution at another place. Moreover, when this nutrient solution adjusting tank is grounded at a place higher than the culture medium 20, a water supply pump is not necessarily required, and the nutrient solution in the nutrient solution adjusting tank can be poured out into the nutrient solution supplying pipe 6 depending on the water level. it can.
養液送水パイプ６は、各培地２０内に養液を供給する為のものであり、少なくとも各培地２０に対して１つ以上の供給口（即ち、養液送水パイプ６の出口）が設けられている。この養液送水パイプ６は、金属や樹脂製のパイプを使用する他、樹脂製のチューブ等を使用することもできる。そして、各培地２０に対する養液の供給は、何れかの培地２０にだけ供給したり、何れかの培地に対して多く又は少なく養液を供給する等、任意に調整できるように形成する事も望ましい。例えば、各培地２０に開口する供給口を開閉自在に形成したり、各培地２０ごとに分岐した養液送水パイプ６に、開閉自在なバルブを設置する等により実現することができる。かかる養液送水パイプ６は、培地２０の底面が長さ方向に傾斜している場合には、水平高さが高い方から養液を供給するように、前記供給口を設置することが望ましい。また、この養液送水パイプ６から各培地２０に対する養液の供給は、培地２０内に直接注入する他、シャワー状にして当該培地２０に供給する事もできる。 The nutrient solution water supply pipe 6 is for supplying a nutrient solution into each medium 20, and at least one supply port (that is, an outlet of the nutrient solution water supply pipe 6) is provided for each medium 20. ing. The nutrient solution water supply pipe 6 may be a metal tube or a resin pipe, or may be a resin tube. The supply of the nutrient solution to each medium 20 may be configured to be arbitrarily adjusted, such as supplying only to any one of the media 20 or supplying more or less nutrient solution to any one of the media. desirable. For example, it can be realized by forming a supply port that opens to each medium 20 so that it can be opened or closed, or by installing a valve that can be opened and closed on the nutrient solution water supply pipe 6 branched for each medium 20. When the bottom surface of the culture medium 20 is inclined in the length direction, it is desirable for the nutrient solution water supply pipe 6 to be provided with the supply port so that the nutrient solution is supplied from the higher horizontal height. Moreover, the supply of the nutrient solution to each culture medium 20 from the nutrient solution water supply pipe 6 can be directly injected into the culture medium 20 or supplied to the culture medium 20 in a shower form.
灌漑水位調整槽３は、各培地２０における水位を調整する為の漕であって、前記養液調整漕から養液送水パイプ６を介して供給された養液を、所定の基準に応じて排水した時に、これを受ける層として機能するものである。ここで、培地２０における養液を調整する基準としては、例えば培地２０における養液の量や、培地２０における養液の滞留時間など、様々な基準で調整することができる。培地２０から灌漑水位調整槽３に対する排水は、金属や樹脂製のパイプ又はチューブを用いて形成した排水パイプ４を使用することができる。また、培地２０から排出される養液等は高低差を利用した自然流出を利用して排水パイプ４により灌漑水位調整槽３に案内することができる他、培地２０から流れ出た養水等を直接灌漑水位調整槽３に落下さセル１１こともできる。培地２０における排水口は、培地２０の底面寄りに形成される事が望ましく、培地２０が長さ方向に傾斜して形成される場合には、低い方に排水口を形成するのが望ましい。なお、この養液調整漕に流入した養水等は、必要に応じて前記養液調整装置５から供給する養水等として再利用する事も考えられる。 The irrigation water level adjusting tank 3 is a tank for adjusting the water level in each medium 20 and drains the nutrient solution supplied from the nutrient solution adjusting tank via the nutrient solution feeding pipe 6 according to a predetermined standard. When it does, it functions as a layer that receives this. Here, as a reference | standard which adjusts the nutrient solution in the culture medium 20, it can adjust with various references | standards, such as the quantity of the nutrient solution in the culture medium 20, and the residence time of the nutrient solution in the culture medium 20, for example. For drainage from the culture medium 20 to the irrigation water level adjustment tank 3, a drainage pipe 4 formed using a pipe or tube made of metal or resin can be used. Further, the nutrient solution discharged from the culture medium 20 can be guided to the irrigation water level adjusting tank 3 by the drainage pipe 4 using natural outflow utilizing the height difference, and the nutrient water etc. flowing out from the culture medium 20 can be directly used. The cell 11 can also be dropped into the irrigation water level adjustment tank 3. The drain port in the culture medium 20 is desirably formed near the bottom surface of the culture medium 20, and when the culture medium 20 is formed to be inclined in the length direction, it is desirable to form the drain port at the lower side. It is also conceivable that the nutrient water or the like that has flowed into the nutrient solution adjusting tank is reused as nutrient water or the like supplied from the nutrient solution adjusting device 5 as necessary.
培地２０は本実施の形態では土壌を凹溝状に掘って形成することができる。図２は当該培地２０の形成状態を示す斜視図であり、この図に示すように、土壌を凹溝状に掘削し、その底面に、高さを有する網目状の底面構成部材７を敷き、法面には溝の内側に平面部８ａを有し、当該平面部８ａにおける溝の外側に向く面に壁状部を形成した法面構成部材８を設置している。そして、凹溝の底面であって、底面構成部材７の近傍には、当該溝１内における円滑な排水を実現する為の排水パイプ４を設置している。そして、当該底面構成部材７と向かい合う法面に設置した法面構成部材８の上には、防水性を有するシート９を被せ、この防水シート９内に培地２０を構成する領域を、圃場の土壌から区画している。この領域の底面には、各培地２０に用水を供給する為の養液送水パイプ６を載せて、この区画された領域１内に培土を敷いて培地２０を完成させている。係る培土としては、適度な培地２０の保水性と透水性の広がりを持たせるため、バーク堆肥、軽石、ピートモス、バーミキュライト等の軽量培地と土砂を適度な配合比で混合して使用することができる。 In the present embodiment, the culture medium 20 can be formed by digging soil into a groove shape. FIG. 2 is a perspective view showing the formation state of the culture medium 20. As shown in this figure, the soil is excavated into a concave groove shape, and a mesh-like bottom surface constituent member 7 having a height is laid on the bottom surface thereof. On the slope, there is provided a slope-constituting member 8 having a flat surface portion 8a inside the groove and having a wall-like portion formed on the surface of the flat surface portion 8a facing the outside of the groove. A drainage pipe 4 for realizing smooth drainage in the groove 1 is installed in the vicinity of the bottom surface component 7 on the bottom surface of the concave groove. Then, a sheet 9 having a waterproof property is placed on the slope component member 8 installed on the slope facing the bottom component member 7, and an area constituting the culture medium 20 is set in the waterproof sheet 9 as soil in the field. It is partitioned from. A nutrient solution water supply pipe 6 for supplying irrigation water to each medium 20 is placed on the bottom surface of this area, and the medium 20 is completed by spreading culture soil in the partitioned area 1. As such a soil, in order to give an appropriate water retention and water permeability of the medium 20, a light medium such as bark compost, pumice, peat moss, vermiculite and earth and sand can be mixed and used in an appropriate mixing ratio. .
図３は、この培地２０を長さ方向に直行する向きで切断した断面図であり、この図に示すように凹状に掘削した溝の底面には、高さを有する網目状の底面構成部材７を敷いている。この底面構成部材７は、図４に示すように、３〜８ｃｍ程度の高さを有するリブからなる網目状の構成とすることができる。かかるリブは木材などの天然樹脂、プラスチック、あるいは金属等を用いて形成することができる。またこの底面構成部材７は、その他にも図５に示すように、樹脂又は金属用いて帯状に形成した帯状部材を曲折させ、曲部に於いて隣り合う帯状部材同士をつなげ合わせて形成する事もできる。このように形成した場合であっても、その高さは３〜８ｃｍ程度とするのが望ましい。このような底面部材を溝の底面に設置する事により、必要以上に高くなっている部分にはこの底面構成部材７が埋まる様に差し込まれ、一方で必要以上に凹んだ部分では、この底面構成部材７が橋架け状に存在する事になる。そして、この底面構成部材７の各セル１１内には土砂が充填される事から、この底面構成部材７を基準として平坦な面を形作ることができる。 FIG. 3 is a cross-sectional view of the culture medium 20 cut in a direction perpendicular to the length direction. As shown in FIG. 3, the bottom surface of the groove excavated in a concave shape has a mesh-like bottom surface constituting member 7 having a height. Laid. As shown in FIG. 4, the bottom surface constituting member 7 can have a mesh-like structure composed of ribs having a height of about 3 to 8 cm. Such ribs can be formed using natural resin such as wood, plastic, or metal.

The slope component member 8 is embedded. The slope component 8 can be formed using resin or metal, and the height of the rib can be approximately 2 to 8 cm. In the embodiment shown in FIG. 6, the rib-like wall portion 8b is extended in the length direction and the width direction of the plane portion 8a, and is formed so as to intersect to form a rectangular cell 11 in plan view. In addition, as shown in FIG. 7, rib-like wall portions 8b are arranged in an inclined manner in the plane of the plane portion 8a, and the cells 11 formed so as to intersect each other have a rhombus in plan view. It can also be formed as follows. Further, as shown in FIG. 8, the wall portion 8b is formed so as to protrude in an annular shape, and the cell 11 having a circular shape in plan view can be formed. The cell 11 composed of the wall portion 8b formed in this manner is filled with earth and sand, and in the state filled with earth and sand, the flat surface portion 8a (the surface on the closed side of the cell 11) in the slope component member 8 Is placed on the slope in the groove with the inside facing the groove. By installing in this way, the earth and sand in the cell 11 is integrated with the earth and sand that constitutes the slope of the groove, so that the wall 8b bites into the spike in a spiked manner, and the slope is held securely. can do. Therefore, even if it is used for many years, the problem that the slope collapses due to wind and rain can be solved.

In particular, in this embodiment, as shown in FIG. 10, the slope-constituting member 8 includes a flat surface portion 8a formed in a strip shape or a plate shape, and a back surface side of the flat surface portion 8a (a surface facing the normal surface of the groove). A wall portion 8b extending obliquely upward and a wall portion 8b extending obliquely downward are formed, and earth and sand are filled between the wall portions 8b and between the wall portion 8b and the flat portion 8a. Thus, the wall 8b is embedded in the cylinder.
また、この実施の形態に係る隔離床栽培施設用ユニット７，８は、前記した底面構成部材７、法面構成部材８の他、更に長さ方向に直行する断面形状が略「コ」字状の畝外保持部材１０を埋設している。この畝外保持部材１０は、培地２０を形成する為に土壌を掘削した際に、溝の縁部分に畝状部分を形成した際、この畝状部分の崩落を阻止する為のものである。かかる畝外保持部材１０は、図１１に示すように、長尺状に形成した帯状部材を長さ方向に沿う折り目を形成して、略「コ」字状に折り曲げて形成することができる。そして、この実施の形態では、畝状部分の上下方向における雨水等の移動を円滑に行うことができるように、折り曲げた領域には複数の貫通孔２１を形成している。かかる畝外保持部材１０を埋設する事により、畝状部分が風雨により崩落するといった問題を解決することができる。 In addition, the isolated floor cultivation facility units 7 and 8 according to this embodiment have a substantially “U” cross-sectional shape that is perpendicular to the length direction in addition to the bottom surface component member 7 and the slope surface component member 8 described above.

As shown in FIG. 11, the outer heel holding member 10 can be formed by forming a long belt-like member into a fold along the length direction and bending it into a substantially “U” shape. In this embodiment, a plurality of through holes 21 are formed in the bent region so that rainwater or the like can be smoothly moved in the vertical direction of the bowl-shaped portion. By embedding the outer cage holding member 10, it is possible to solve the problem that the bowl-shaped portion collapses due to wind and rain.
そして図１３は更に他の実施の形態に係る培地２０の長さ方向に沿う向きの断面図であり、この図に於いては特に底面構成部材７を、図１３に示すように、長尺な帯状部材を、その長さ方向に山折りと谷折りを交互に繰り返して曲折させて形成している。そしてこの実施の形態にかかる底面構成部材７では、その面内に厚さ方向に貫通する複数の貫通孔２１を形成している。この貫通孔２１は土中に接地した状態において、雨水が溜まってしまうことを阻止するためのものである。このように形成した底面構成部材７によれば、培地２０の底面は、この折り曲げて形成した底面構成部材７の頂部の高さによって確定することができることから、培地２０の底面を平坦にすることができる。 FIG. 13 is a cross-sectional view in the direction along the length direction of the culture medium 20 according to still another embodiment. In this figure, the bottom constituent member 7 is particularly long as shown in FIG. The band-shaped member is formed by bending a mountain fold and a valley fold alternately in the length direction thereof and bending it. And in the bottom surface structural member 7 concerning this embodiment, the several through-hole 21 penetrated in the thickness direction in the surface is formed. This through hole 21 is for preventing rainwater from accumulating in a state where it is grounded in the soil. According to the bottom surface forming member 7 formed in this way, the bottom surface of the culture medium 20 can be determined by the height of the top of the bottom surface forming member 7 formed by bending, so that the bottom surface of the culture medium 20 is flattened. Can do.
