Description

本発明は、人工照明装置や空調装置を装備した外部環境の影響を受けない安定した雰囲気内で、植物を効率よく育成することができる植物育成ユニット、およびこの植物育成ユニットを用いた多段式植物育成装置に関するものである。   The present invention relates to a plant growing unit capable of efficiently growing a plant in a stable atmosphere not affected by the external environment equipped with an artificial lighting device or an air conditioner, and a multi-stage plant using the plant growing unit The present invention relates to a training apparatus.

ナス科、ウリ科などの果菜類では、各々を穂木とし、それに台木を接ぎ木した接ぎ木苗を育成することにより、台木の持つ特性と穂木の持つ特性を生かし生産性や病害抵抗性を高める方法が広く採用されている。
接ぎ木苗の台木と穂木の維管束組織がつながる活着を促進させ、台木から穂木への水分や養分の移動、穂木での光合成による同化産物の台木への移動を可能とさせるためには、接ぎ木後に接ぎ木苗が置かれる環境条件が重要となる。接ぎ木直後の数日間の細かな環境調節期間を養生と称し、養生期間中は高湿度、低日照の条件下で台木と穂木の気孔などからの水分の蒸発散が制限され、台木穂木がしおれることなく活着を促進させることができる。 In fruit and vegetables such as solanaceae and cucurbitaceae, each plant is made into a panicle, and by growing grafted seedlings grafted with a rootstock, productivity and disease resistance can be achieved by taking advantage of the characteristics of the rootstock and the characteristics of the panicle. A method for increasing the frequency is widely adopted.
Promotes the establishment of the connection between the grafted rootstock and the vascular tissue of the hogi, enabling the transfer of moisture and nutrients from the rootstock to the hogi and the transfer of assimilation products to the rootstock by photosynthesis in the hogi For this purpose, the environmental conditions in which the grafted seedlings are placed after grafting are important. The fine environmental conditioning period for several days immediately after grafting is called curing, and during the curing period, the evapotranspiration of roots and panicles is restricted under conditions of high humidity and low sunshine. The survival can be promoted without wilting the trees.

台木と穂木の育苗から接ぎ木苗の育苗、さらには接ぎ木苗の養生まで一貫して行える育苗装置に関しては、例えば特許文献１で提案されている。
この育苗装置は、図１０に示したように、苗を搭載しうる複数枚の棚板６２を備えた多段式の育苗棚６１を遮光性断熱壁からなる閉鎖型構造物６０内に設置し、育苗棚６１各段には、搭載された苗に投光しうる人工照明装置６３および各段に空気流を生じさせるファン６４を設けてある。さらに閉鎖型構造物６０内には、構造物内雰囲気を調温調湿する空調装置６５と炭酸ガスを供給する炭酸ガス施用装置６６が設けてある。 For example, Patent Document 1 proposes a seedling raising apparatus that can perform consistently from raising seedlings and hogi seedlings to grafting seedlings, and further grafting seedling curing.
As shown in FIG. 10, this seedling raising apparatus is provided with a multistage seedling shelf 61 provided with a plurality of shelf boards 62 on which seedlings can be mounted in a closed structure 60 made of a light-shielding heat insulating wall. Each stage of the nursery rack 61 is provided with an artificial lighting device 63 that can project the mounted seedlings and a fan 64 that generates an air flow in each stage. Further, in the closed structure 60, an air conditioner 65 for adjusting the temperature and humidity of the atmosphere in the structure and a carbon dioxide application device 66 for supplying carbon dioxide are provided.

図１１には、育苗棚６１の１つの棚板６２に搭載された接ぎ木苗６７を示しており、複数本の接ぎ木苗６７をアンダートレイ６８上のセルトレイ６９の各セルに植えた形で棚板に搭載される。特許文献１においては、図１２に図示したごとき、例えば透明アクリル樹脂からなる底板のない箱形状を有し、複数の通気孔７１を備えた透光性遮蔽物７０を用いて、接ぎ木苗の養生期間中、各棚板６２に搭載された接ぎ木苗６７を被覆する。   FIG. 11 shows a grafted seedling 67 mounted on one shelf 62 of the seedling rack 61, and a plurality of grafted seedlings 67 are planted in each cell of the cell tray 69 on the under tray 68. Mounted on. In Patent Document 1, as shown in FIG. 12, for example, a grafted seedling is cured using a translucent shield 70 having a box shape made of a transparent acrylic resin without a bottom plate and provided with a plurality of air holes 71. During the period, the grafted seedling 67 mounted on each shelf 62 is covered.

特許文献１の育苗装置を用いて接ぎ木苗を育成する方法は、先ず、各育苗棚６１で台木と穂木を別個に育苗する。台木と穂木の育苗は、各棚板６２に搭載したセルトレイ６９の各セルに苗を植え、透光性遮蔽物７０を被覆せずに行う。この育苗は、閉鎖型構造物６０内の調温調湿された雰囲気で適切な人工照明の下で行われるため、自然光育成に比べて樹勢の強い元苗（台木、穂木）が得られる。
こうして育苗された台木と穂木を育苗棚６１から取り出し、それぞれ切断して、例えば切断面を互いに合わせてクリップなどの支持具でとめる合わせ接ぎなどの方法で接ぎ木苗６７を作成する。 In the method for growing grafted seedlings using the seedling raising apparatus of Patent Document 1, first, rootstocks and spikelets are raised separately in each seedling shelf 61. Raising seedlings and panicles is carried out without planting seedlings in each cell of the cell tray 69 mounted on each shelf 62 and covering the translucent shield 70. Since this seedling is performed under appropriate artificial lighting in a temperature-controlled and humidity-controlled atmosphere in the closed structure 60, original seedlings (rootstock, hogi) that are stronger than natural light growth are obtained. .
The rootstock and the hogi thus grown are taken out from the nursery rack 61 and cut respectively, and a grafted seedling 67 is created by a method such as mating and joining such that the cut surfaces are aligned with each other with a support such as a clip.

これらの接ぎ木苗は、次いで図１１に示すように、セルトレイ６９の各セルに植え、これを育苗棚の各棚板６２の上に置き透光性遮蔽物７０で被覆して養生を行う。養生期間中も、透光性遮蔽物７０を通して接ぎ木苗６７に通常の養生より高い光強度で投光するとともに、育苗棚各段に設けたファン６４で各段毎に空気流を生じさせながら、空調装置６５で閉鎖型構造物内を調温調湿し、さらに炭酸ガス施用装置６６で閉鎖型構造物内に炭酸ガスを供給する。
接ぎ木苗の養生期間中、台木と穂木の活着を促進するためには高い相対湿度が必要となるが、透光性遮蔽物７０内部は、接ぎ木苗から水分が蒸発して相対湿度が９０〜１００％に高まり、活着が促進される。 Next, as shown in FIG. 11, these grafted seedlings are planted in each cell of the cell tray 69, placed on each shelf plate 62 of the seedling rack and covered with a light-transmitting shield 70, and cured. During the curing period, the grafted seedlings 67 are projected with higher light intensity than the normal curing through the translucent shield 70, and the fan 64 provided in each stage of the seedling rack generates an air flow for each stage. The temperature of the closed structure is controlled by the air conditioner 65, and the carbon dioxide gas is supplied into the closed structure by the carbon dioxide application device 66.
During the curing period of the grafted seedling, a high relative humidity is required to promote the survival of rootstocks and panicles. However, the moisture inside the translucent shield 70 evaporates from the grafted seedling and the relative humidity is 90%. It increases to ˜100%, and the survival is promoted.

一方、活着が促進されながら通常より高い光強度の下で接ぎ木苗の光合成が活発に行われるようになると、遮光性遮蔽物７０内の炭酸ガス濃度が低下してくるため、光合成速度の低下要因となる。そのため、透光性遮蔽物７０の壁面には、図１１および図１２に示したように、透光性遮蔽物７０内部の加湿状態を損なわない程度の大きさの複数の通気孔７１が設けてある。これによって、ファン６４による育苗棚各段に生じている空気流により、透光性遮蔽物７０の通気孔７１を通じてガス交換がなされ、閉鎖型構造物６０内の炭酸ガス含有雰囲気を透光性遮蔽物７０内へ供給でき、接ぎ木苗の光合成に伴って減少する炭酸ガスを補充し、接ぎ木苗の光合成を促進することができる。
一般に養生後の接ぎ木苗は、光強度を徐々に強める順化を行う必要があるが、遮光性遮蔽物７０を用いて養生する場合、通常より強い光強度を与えることができるため、養生中の光合成が促進されることにより、順化工程そのものを省略できる。 On the other hand, if photosynthesis of the grafted seedling is actively performed under light intensity higher than usual while promoting engraftment, the concentration of carbon dioxide gas in the light shielding shield 70 is reduced, which causes a decrease in the photosynthetic rate. It becomes. Therefore, as shown in FIGS. 11 and 12, a plurality of ventilation holes 71 having a size that does not impair the humidified state inside the translucent shield 70 are provided on the wall surface of the translucent shield 70. is there. Thus, gas exchange is performed through the air holes 71 of the light-transmitting shield 70 by the air flow generated in each stage of the nursery shelf by the fan 64, and the carbon dioxide-containing atmosphere in the closed structure 60 is light-shielded. The carbon dioxide gas that can be supplied into the object 70 and decreases with the photosynthesis of the grafted seedling can be supplemented to promote the photosynthesis of the grafted seedling.
In general, grafted seedlings after curing need to be acclimatized to gradually increase the light intensity. However, when curing using the light-shielding shield 70, it is possible to give stronger light intensity than usual. By promoting photosynthesis, the acclimatization process itself can be omitted.

上述した植物育成ユニットは、複数段の棚板を備えた育成棚の各段に載置し、この育成棚を閉鎖型構造物内に配置することにより、多段式の植物育成装置とすることもできる。
すなわち本発明の多段式植物育成装置は、遮光性断熱壁で包囲された閉鎖型構造物内に、上下方向に複数段の棚板を備え請求項１に記載の植物育成ユニットを棚板の各段に載置した多段式の育成棚を設置し、前記育成棚の各段には、載置した前記植物育成ユニットに投光しうる人工照明装置および各段に空気流を生じさせるファンを設け、前記閉鎖型構造物内を調温調湿しうる空調装置および閉鎖型構造物内に炭酸ガスを供給しうる炭酸ガス供給装置を設けたことを特徴とするものである。
前記各段に設けたファンは、風量調節が可能なファンとすることが望ましい。 The plant growing unit described above is placed on each stage of a growing shelf provided with a plurality of stages of shelf boards, and this growing shelf is arranged in a closed structure, whereby a multi-stage plant growing apparatus can be obtained. it can.
That is, the multi-stage plant growing apparatus of the present invention comprises a plurality of shelves in the vertical direction in a closed structure surrounded by a light-shielding heat insulating wall, and the plant growing unit according to claim 1 is provided for each of the shelves.

As a result, when raising the grafted seedlings, it is possible to eliminate the necessity of performing the attaching / detaching work such as removing the conventional detachable translucent shield when raising the original seedlings and covering the seedlings when curing the grafted seedlings.
Furthermore, the plant growing environment in the growing unit can be appropriately managed by adjusting the degree of opening of the growing unit door and the opening ratio of the rear slit-shaped opening.

また、育成ユニットの遮蔽状態において、給水口からのかん水停止時に、必要に応じて排水口から温湿度および炭酸ガス濃度を調整した空気流を育成ユニット内に供給することができ、これによって遮蔽状態であっても育成ユニット内の植物育成環境をきめ細かく制御することができる。   In addition, when the irrigation unit is in a shielded state, when the water supply from the water supply port is stopped, an air flow adjusted in temperature, humidity, and carbon dioxide concentration can be supplied from the drainage port to the cultivating unit as necessary. Even so, the plant growing environment in the growing unit can be finely controlled.

本発明の育成ユニットは、複数段の棚板を備えた育成棚の各段に載置し、この育成棚を閉鎖型構造物内に配置して多段式の植物育成装置として構成することもできる。かような多段式装置の場合、育苗棚の段数が多くなるが、本発明の育成ユニットを使用することによって、従来の着脱自在の透光性遮蔽物のような着脱作業が不要になるため、作業時間の大幅な短縮が可能となる。   The growing unit of the present invention can be configured as a multi-stage plant growing apparatus by placing it on each stage of a growing shelf having a plurality of stages of shelves and arranging the growing shelf in a closed structure. . In the case of such a multi-stage device, the number of stages of the seedling rack is increased, but by using the growing unit of the present invention, it becomes unnecessary to attach and detach such as a conventional detachable translucent shield, Work time can be greatly reduced.

図１および図２を参照して、本発明の植物育成ユニットの好ましい実施形態を説明する。
育成ユニット１０の基本形状は、四辺形の底壁１１と、底壁の四辺から立ち上げた４つの側壁１２ａ、１２ｂ、１２ｃ、１２ｄと、これら側壁の上に載置した頂壁１３とからなる箱形状を有している。
本発明の育成ユニット１０は、かん水装置を一体構造として具備しており、このかん水装置は、図１の部分切欠拡大図である図２に示したように、底壁１１の一辺の両端近傍にそれぞれ設けた給水口１４と排水口１５を有し、排水口１５を囲むように所定の高さの堰１６を配設する。この堰１６の高さは、底壁１１面上に所定の水位でかん水できるような高さとする。給水口１４から水または養液（以下これらを単に“水”と総称する）を供給することにより底壁１１面上にかん水することができ、堰１６の高さまでかん水すると堰１６から余分の水がオーバーフローすることで所定水位を保つことができる。 A preferred embodiment of the plant growing unit of the present invention will be described with reference to FIGS. 1 and 2.
The basic shape of the growing unit 10 includes a quadrilateral bottom wall 11, four side walls 12a, 12b, 12c, and 12d raised from the four sides of the bottom wall, and a top wall 13 placed on these side walls. It has a box shape.
The nurturing unit 10 of the present invention has a watering device as an integral structure, and this watering device is located near both ends of one side of the bottom wall 11 as shown in FIG. Each has a water supply opening 14 and a water discharge opening 15, and a weir 16 having a predetermined height is disposed so as to surround the water discharge opening 15. The height of the weir 16 is set to a height at which water can be irrigated at a predetermined water level on the surface of the bottom wall 11. By supplying water or nutrient solution (hereinafter simply referred to as “water”) from the water supply port 14, water can be poured onto the surface of the bottom wall 11. The predetermined water level can be maintained by overflowing.

堰１６の下端部には、堰下端を切り欠いて形成した切欠開口１６ａを設けてある。この切欠開口１６ａは、堰１６の高さまでかん水した後、かん水を停止した際に、底壁面上に溜まった水を排水口１５から速やかに排出させる機能を有している。さらに、かん水時には切欠開口１６ａから絶えず水が排出されるため、給水口１４からの供給量と切欠開口１６ａからの排出量とのバランスを変化させることによって、堰１６の高さより低い水位を保つことができる機能も有している。   The lower end of the weir 16 is provided with a notch opening 16a formed by notching the lower end of the weir. The notch opening 16 a has a function of quickly draining water accumulated on the bottom wall surface from the drain outlet 15 when irrigation is stopped after irrigation to the height of the weir 16. Furthermore, since water is continuously discharged from the notch opening 16a during watering, the water level lower than the height of the weir 16 can be maintained by changing the balance between the supply amount from the water supply port 14 and the discharge amount from the notch opening 16a. It also has a function that can.

給水口１４および排水口１５を設けた底壁１１の一辺から立ち上げた側壁１２ａの、堰１６より高い部分を、蝶番１７により開閉できる扉１８とする。この扉１８を育成ユニット１０外側に倒して開状態とすることにより（図１の一点鎖線参照）、育成ユニット１０内で育成する苗を植えたセルトレイ等を出し入れすることができる。扉１８部分を堰１６の高さより高い位置に形成してあるため、育成ユニット１０内にかん水した水が扉１８部分から漏出する心配がない。
また、育成ユニット底壁１１面は、扉１８の背面から扉方向に緩やかな傾斜を設けることにより、かん水停止時に切欠開口１６ａから速やかに排水させることが可能となる。 A portion higher than the weir 16 on the side wall 12 a raised from one side of the bottom wall 11 provided with the water supply port 14 and the drain port 15 is defined as a door 18 that can be opened and closed by a hinge 17. By bringing the door 18 to the outside of the growing unit 10 to be in an open state (see the one-dot chain line in FIG. 1), a cell tray or the like planted with seedlings to be grown in the growing unit 10 can be taken in and out. Since the door 18 portion is formed at a position higher than the height of the weir 16, there is no fear that water that has been irrigated into the growing unit 10 leaks from the door 18 portion.
Further, the surface of the growing unit bottom wall 11 can be drained promptly from the notch opening 16a when the irrigation is stopped by providing a gentle slope in the door direction from the rear surface of the door 18.

扉１８に対して後側、すなわち扉１８の背面に位置する側壁１２ｂには、複数の背面スリット状開口２０が形成されている。この背面スリット状開口２０は、全開から全閉まで開口率を変化させる手段が備えられている。開口率を変化させる手段は特に限定されないが、例えば図３に示したような、開口率調整板２１を使用することができる。この開口率調整板２１には、背面側壁１２ｂに形成した複数の背面スリット状開口２０と形状、寸法が略同じ複数のスリット状開口２２が形成されており、背面側壁１２ｂ外面に固定した一組の案内枠２３、２３により背面側壁１２ｂの外面にスライド自在に保持されている。この開口率調整板２１を、背面側壁１２ｂ外面に対してスライドさせることにより、図４（Ａ）に示したように、背面スリット状開口２０と開口率調整板２１のスリット状開口２２とが全く重ならない位置では開口率０％（全閉）、図４（Ｂ）に示したように半分重なった位置では開口率５０％（半開）、図４（Ｃ）に示したように完全に重なった位置では開口率１００％（全開）の状態となり、全開から全閉までの間で任意の開口率に変化させることができる。   A plurality of rear slit-like openings 20 are formed on the side wall 12b located on the rear side of the door 18, that is, on the back surface of the door 18. The rear slit-like opening 20 is provided with means for changing the opening ratio from fully open to fully closed. The means for changing the aperture ratio is not particularly limited. For example, an aperture ratio adjusting plate 21 as shown in FIG. 3 can be used. The aperture ratio adjusting plate 21 is formed with a plurality of slit-like openings 22 having substantially the same shape and dimensions as the plurality of back-side slit-like openings 20 formed on the back-side wall 12b, and a set fixed to the outer surface of the back-side wall 12b. The guide frames 23 and 23 are slidably held on the outer surface of the rear side wall 12b. By sliding the aperture ratio adjusting plate 21 with respect to the outer surface of the rear side wall 12b, the rear slit-shaped opening 20 and the slit-shaped opening 22 of the aperture ratio adjusting plate 21 are completely removed as shown in FIG. When the position does not overlap, the aperture ratio is 0% (fully closed). As shown in FIG. 4 (B), the aperture ratio is 50% (half open), and as shown in FIG. 4 (C), the aperture is completely overlapped. At the position, the aperture ratio is 100% (fully open), and the aperture ratio can be changed to an arbitrary aperture ratio from fully open to fully closed.

さらに、図１に示したように、扉１８の両側に立設した側壁１２ｃ、１２ｄの上部には、複数の通気孔２４が設けられている。この通気孔２４は、背面スリット状開口２０が全閉の状態においても、育成ユニット内部雰囲気と育成ユニット外部雰囲気とのある程度の流通を行わせる機能を有し、背面スリット状開口２０よりも小さく形成されている。なお、この通気孔２４も、全開から全閉まで開孔率を変化させる手段を備えることが望ましい。通気孔２４の開孔率を変化させる手段は特に限定されないが、図５に示したような開孔率調整板２５を使用することができる。この開孔率調整板２５も、背面スリット状開口２０の開口率調整板２１と同様に、側壁１２ｃに形成した複数の通気孔２４に対応する複数の通気孔２６を備えており、側壁１２ｃ外面に固定した一組の案内枠２７、２７により側壁１２ｃの外面に対してスライドさせることにより、通気孔２６の開孔率を全開から全閉までの間で任意の開孔率に変化させることができる。   Further, as shown in FIG. 1, a plurality of vent holes 24 are provided on the upper portions of the side walls 12 c and 12 d erected on both sides of the door 18. The vent hole 24 has a function of allowing a certain degree of circulation between the atmosphere inside the growing unit and the atmosphere outside the growing unit even when the back slit-shaped opening 20 is fully closed, and is formed smaller than the back slit-shaped opening 20. Has been. In addition, it is desirable that the vent hole 24 also includes means for changing the opening ratio from fully open to fully closed. The means for changing the aperture ratio of the vent hole 24 is not particularly limited, but an aperture ratio adjusting plate 25 as shown in FIG. 5 can be used. The aperture ratio adjusting plate 25 also includes a plurality of vent holes 26 corresponding to the plurality of vent holes 24 formed in the side wall 12c, similar to the aperture ratio adjusting plate 21 of the rear slit-like opening 20, and the outer surface of the side wall 12c. By sliding a pair of guide frames 27, 27 fixed to the outer surface of the side wall 12c, the aperture ratio of the vent hole 26 can be changed to an arbitrary aperture ratio from fully open to fully closed. it can.

かような構造の育成ユニット１０は、人工照明下に置かれて使用されるために、少なくとも頂壁１３と扉１８部分はアクリル樹脂等の透光性材料とする必要があるが、他の側壁１２ｂ、１２ｃ、１２ｄも透光性材料としてもよい。   Since the growing unit 10 having such a structure is used under artificial lighting, at least the top wall 13 and the door 18 need to be made of a light-transmitting material such as acrylic resin. 12b, 12c, and 12d may also be translucent materials.

上述した本発明による植物育成ユニットの使用例を、接ぎ木苗の育成を例に挙げて説明する。
育成ユニット１０は、調温調湿され炭酸ガス濃度を調整された雰囲気内の人工照明下に静置される。雰囲気にはファン等により空気流を発生させ、空気流が育成ユニットの扉１８側から背面側へ流れるようにすることが望ましい。
この育成ユニットを用いて、先ず元苗（台木と穂木）を育苗する。元苗の育成に際しては、育成ユニットの扉１８を開け、底壁１１面の上にアンダートレイを置き、その上に、各トレイに元苗を植えたセルトレイを載置し、扉１８と背面スリット状開口２０を開状態としておく。
これによって、育成ユニットを取り囲む温湿度および炭酸ガス濃度を調整された雰囲気が開状態の扉１８から育成ユニット内に流れ込み、適切な人工照明の下に元苗の育苗がなされる。その結果、自然光育成に比べて樹勢の強い元苗が得られる。元苗の育苗期間においては、育成ユニットの給水口１４から適宜かん水を行い、セルトレイに植えられた元苗に底面かん水がなされる。 The usage example of the plant growing unit according to the present invention described above will be described by taking the growth of grafted seedlings as an example.
The growing unit 10 is placed under artificial lighting in an atmosphere in which the temperature is adjusted and the concentration of carbon dioxide gas is adjusted. It is desirable that an air flow is generated in the atmosphere by a fan or the like so that the air flow flows from the door 18 side to the back side of the growing unit.
Using this breeding unit, first, seedlings (stockstock and hogi) are raised. When growing the seedlings, the door 18 of the growing unit is opened, an under tray is placed on the surface of the bottom wall 11, and cell trays in which the seedlings are planted are placed on the trays. The shaped opening 20 is left open.
As a result, an atmosphere in which the temperature and humidity and the concentration of carbon dioxide gas surrounding the growing unit are adjusted flows into the growing unit from the open door 18, and the original seedling is raised under appropriate artificial lighting. As a result, an original seedling having a strong tree vigor compared to natural light breeding can be obtained. During the breeding period of the original seedling, watering is appropriately performed from the water supply port 14 of the growing unit, and bottom watering is performed on the original seedling planted in the cell tray.

こうして育苗された台木と穂木が植えられたセルトレイを育成ユニットの開状態とされている扉から取り出し、それぞれを切断して切断面を接合させ接ぎ木苗を作成する。
これらの接ぎ木苗は、従来と同様に図１１に示したようにして、再びセルトレイの各セルに植えられ、このセルトレイを育成ユニットの底壁１１面に敷かれたアンダートレイの上に載置した後、育成ユニットの扉１８と背面スリット状開口２０を閉状態として、人工照明下で接ぎ木苗の養生を行う。
接ぎ木苗の養生期間中、台木と穂木の活着を促進するためには高い相対湿度が必要となるが、閉状態とされた育成ユニット１０内部は、接ぎ木苗から水分が蒸発して相対湿度が９０〜１００％に高まり、活着が促進される。 The cell tray on which the rootstock and the spikelets thus grown are planted is taken out from the open door of the growing unit, and each is cut and joined to create a grafted seedling.
These grafted seedlings were planted again in each cell of the cell tray as shown in FIG. 11 as in the conventional case, and this cell tray was placed on the under tray placed on the bottom wall 11 surface of the growing unit. Thereafter, the door 18 and the rear slit-shaped opening 20 of the growing unit are closed, and the grafted seedling is cured under artificial lighting.
During the curing period of grafted seedlings, high relative humidity is required to promote the survival of rootstocks and panicles, but the inside of the growing unit 10 in a closed state causes relative moisture to evaporate from the grafted seedlings. Increases to 90 to 100%, and the survival is promoted.

活着が促進されながら通常より高い光強度の下で接ぎ木苗の光合成が活発に行われるようになると、閉状態とされた育成ユニット１０内の炭酸ガス濃度が低下してくるため、光合成速度の低下要因となる。そのため、育成ユニットの扉１８両側の側壁１２ｃ、１２ｄには、図１および図５に示したように、育成ユニット内部の加湿状態を損なわない程度の大きさの複数の通気孔２４が設けてある。これらの通気孔２４を通じてガス交換がなされ、育成ユニット外部の炭酸ガス含有雰囲気を育成ユニット内へ供給でき、接ぎ木苗の光合成に伴って減少する炭酸ガスを補充し、接ぎ木苗の光合成を促進することができる。なお、ガス交換の機能を有する複数の通気孔２４も、図５に示したような全開から全閉まで開孔率を変化させる手段を設けることで、ガス交換量を任意に調節することが可能となり、光合成速度に応じて育成ユニット内部の炭酸ガス量をきめ細かく制御することができる。   When photosynthesis of grafted seedlings is actively carried out under light intensity higher than usual while promoting engraftment, the concentration of carbon dioxide in the growing unit 10 in a closed state is lowered, so the photosynthesis rate is reduced. It becomes a factor. Therefore, the side walls 12c and 12d on both sides of the door 18 of the growing unit are provided with a plurality of vent holes 24 having a size that does not impair the humidified state inside the growing unit, as shown in FIGS. . Gas exchange is performed through these vent holes 24, and a carbon dioxide-containing atmosphere outside the growing unit can be supplied into the growing unit, and carbon dioxide that decreases with the photosynthesis of the grafted seedling is supplemented to promote photosynthesis of the grafted seedling. Can do. The plurality of vent holes 24 having a gas exchange function can also be adjusted arbitrarily by providing means for changing the hole area ratio from fully open to fully closed as shown in FIG. Thus, the amount of carbon dioxide in the growing unit can be finely controlled according to the photosynthetic rate.

一般に養生後の接ぎ木苗は、光強度を徐々に強める順化を行う必要があるが、本発明による育成ユニットを用いて養生する場合、通常より強い光強度を与えることができるため、養生中の光合成が促進されることにより、順化工程そのものを省略できる。   Generally, grafted seedlings after curing need to be acclimatized to gradually increase the light intensity, but when curing using the growing unit according to the present invention, it is possible to give stronger light intensity than usual, so during curing By promoting photosynthesis, the acclimatization process itself can be omitted.

上述したごとき接ぎ木苗の育苗に本発明の育成ユニットを使用する場合、元苗の育苗期間および接ぎ木苗の養生期間を通じて、扉１８開き具合や背面スリット状開口２０の開口率を適切に調節することにより、育苗期間中や養生期間中の苗の生育状態に応じた最適な育成環境に管理することが可能となる。   When using the breeding unit of the present invention for raising grafted seedlings as described above, appropriately adjust the degree of opening of the door 18 and the opening ratio of the rear slit-like opening 20 throughout the nursery period of the original seedling and the curing period of the grafted seedling. By this, it becomes possible to manage to the optimal breeding environment according to the growth state of the seedling during the raising seedling period and the curing period.

育成ユニットを閉状態として接ぎ木苗の養生を行う場合、育成ユニット内雰囲気の温度と湿度および炭酸ガス濃度をより確実に制御するために、温湿度および炭酸ガス濃度を調節された空気流を積極的に閉状態の育成ユニット内へ供給することも必要となる。この場合には、かん水停止期間の育成ユニット排水口１５を介して温湿度および炭酸ガス濃度を調整された空気流を育成ユニット内へ供給することもできる。また、排水口１５から供給した空気流を育成ユニット内へ均一に拡散させるために、図６に図示したような拡散パイプ３０を排水口１５に嵌合して使用することができる。この拡散パイプ３０は、Ｌ型の排水口嵌合部３１とＴ型の拡散部３２とをパイプで連結した構造を備え、図７に示したように、排水口嵌合部３１先端を育成ユニットの排水口１５に嵌合したときに、Ｔ型拡散部３２が育成ユニットの幅方向略中央部に位置するように設置する。この状態で、温湿度および炭酸ガス濃度を調節された空気を排水口１５から導入することにより、拡散パイプ３０の排水口嵌合部３１からＴ型拡散部３２へ空気流が導かれ、Ｔ型拡散部３２の横方向両端開口３２ａ、３２ｂから育成ユニット内へ均一に分散供給することができる。育成ユニットの給水口１４からのかん水時には、Ｌ型排水口嵌合部３１は排水口１５から外され、拡散パイプ３０全体が育成ユニット外部へ搬出される。   When grafting seedlings are cured with the growing unit closed, an air flow with adjusted temperature and humidity and carbon dioxide concentration is actively used to control the temperature, humidity and carbon dioxide concentration in the growing unit more reliably. It is also necessary to supply it to the closed growth unit. In this case, an air flow in which the temperature and humidity and the carbon dioxide gas concentration are adjusted can be supplied into the growth unit through the growth unit drain port 15 in the watering stop period. Further, in order to uniformly diffuse the air flow supplied from the drain port 15 into the growing unit, a diffusion pipe 30 as shown in FIG. 6 can be fitted to the drain port 15 and used. The diffusion pipe 30 has a structure in which an L-shaped drain port fitting portion 31 and a T-shaped diffusion portion 32 are connected by a pipe, and as shown in FIG. The T-shaped diffusion part 32 is installed so as to be positioned at a substantially central part in the width direction of the growing unit when fitted to the drainage port 15. In this state, air whose temperature and humidity and the concentration of carbon dioxide gas are adjusted is introduced from the drain port 15, whereby an air flow is guided from the drain port fitting portion 31 of the diffusion pipe 30 to the T-type diffusion portion 32. The diffuser 32 can be uniformly distributed from the lateral end openings 32a and 32b into the growth unit. At the time of watering from the water supply port 14 of the growing unit, the L-shaped drain port fitting portion 31 is removed from the drain port 15 and the entire diffusion pipe 30 is carried out of the growing unit.

背面スリット状開口２０の開口率を調節する手段として、図３に示したような育成ユニット背面側壁１２ｂの外面にスライド自在に設けた開口率調整板２１を使用する場合、開口率調整板２１と係合するレバー４０（図１参照）を育成ユニットの頂壁１３面上に背面側から扉側に延設し、このレバー４０の操作により開口率調整板２１をスライドできるようにすることが望ましい。図１に示す実施例においては、レバー４０はピン４１を中心としてその基端部４０ａと先端部４０ｂが回動し、レバー先端部４０ｂにはＬ型部材４３がピン４２により回動自在に取り付けられており、Ｌ型部材４３の下端は開口率調整板２１（図３参照）に固着されている。かような構造とすることにより、レバーの基端部４０ａを左右に移動させると、レバー先端部４０ｂは逆方向に左右に移動し、レバー先端部４０ｂと同方向にＬ型部材４３も左右に移動する。Ｌ型部材４３の左右への移動に伴って、開口率調整板２１も左右へスライドする。開口率調整板２１のスライドは、図４（Ａ）〜（Ｃ）に図示したように、背面スリット状開口２０の１個分だけスライドさせることにより開口率１００％（全開）から開口率０％（全閉）まで変化させることができる。したがってレバー基端部４０ａは、開口率調整板２１を背面スリット状開口２０の１個分だけ左右に移動させることができる範囲で移動させればよく、それ以上移動させないようにするためにストッパー４４によりその移動範囲を規制する。   As a means for adjusting the aperture ratio of the rear slit-shaped opening 20, when using the aperture ratio adjusting plate 21 slidably provided on the outer surface of the rear wall 12b of the rearing unit as shown in FIG. It is desirable that the lever 40 (see FIG. 1) to be engaged is extended from the rear side to the door side on the top wall 13 surface of the growing unit so that the aperture ratio adjusting plate 21 can be slid by operating the lever 40. . In the embodiment shown in FIG. 1, the lever 40 has a base end portion 40a and a distal end portion 40b pivoted about a pin 41, and an L-shaped member 43 is rotatably attached to the lever distal end portion 40b by a pin 42. The lower end of the L-shaped member 43 is fixed to the aperture ratio adjusting plate 21 (see FIG. 3). With this structure, when the base end portion 40a of the lever is moved to the left and right, the lever front end portion 40b moves to the left and right in the opposite direction, and the L-shaped member 43 also moves to the left and right in the same direction as the lever front end portion 40b. Moving. As the L-shaped member 43 moves left and right, the aperture ratio adjustment plate 21 also slides left and right. As shown in FIGS. 4A to 4C, sliding of the aperture ratio adjusting plate 21 is performed by sliding only one of the rear slit-shaped openings 20 from an aperture ratio of 100% (fully open) to an aperture ratio of 0%. It can be changed to (fully closed). Therefore, the lever base end portion 40a may be moved within a range in which the aperture ratio adjusting plate 21 can be moved to the left and right by one of the rear slit-like openings 20, and the stopper 44 is provided so as not to move further. The movement range is regulated by

育成ユニットの扉１８を開くことにより背面スリット状開口２０が開状態となり、扉１８を閉じることにより背面スリット状開口２０が閉状態となるようにするためには、扉１８の開動作と背面スリット状開口２０を開状態にするための開口率調整板２１スライド動作とが連動し、かつ、扉１８の閉動作と背面スリット状開口２０を閉状態にするための開口率調整板２１スライド動作とが連動する手段を設けることが望ましい。かような手段の一例として、図８に示したように、育成ユニットの扉１８の外面一端と、開口率調整板２１の外面一端とを、２個のローラ５０、５１を介してワイヤ５２で接続し、開口率調整板２１を全閉状態（図の左側）に絶えず引っ張るスプリング５３を開口率調整板２１の外面多端に配設した構造が考えられる。   In order to open the rear slit-shaped opening 20 by opening the door 18 of the growing unit and to close the rear slit-shaped opening 20 by closing the door 18, the opening operation of the door 18 and the rear slit are performed. The opening ratio adjusting plate 21 sliding operation for opening the cylindrical opening 20 is interlocked, and the closing operation of the door 18 and the opening ratio adjusting plate 21 sliding operation for closing the rear slit-shaped opening 20 are performed. It is desirable to provide means for interlocking. As an example of such means, as shown in FIG. 8, one end of the outer surface of the door 18 of the growing unit and one end of the outer surface of the aperture ratio adjusting plate 21 are connected by a wire 52 via two rollers 50 and 51. A structure may be considered in which springs 53 that are connected and continuously pull the aperture ratio adjusting plate 21 to the fully closed state (the left side in the figure) are arranged on the outer surface multi-end of the aperture ratio adjusting plate 21.

すなわち、図８は、育成ユニットの扉１８が閉とされている状態を示し、スプリング５３により開口率調整板２１は図の左側に引っ張られていて、開口率調整板２１のスリット状開口２２と、育成ユニット背面壁１２ｂの背面スリット状開口２０とが全く重なっていない全閉（開口率０％）の状態となっている。
図９は、育成ユニットの扉１８を開とした状態を示し、扉１８の開動作に伴ってワイヤ５２が２つのローラ５０、５１を回転させながら矢印の方向に引っ張られ、開口率調整板２１を図の右側へスライドさせる。このときスプリング５３は図の右側（矢印方向）に引き延ばされ、開口率調整板２１のスリット状開口２２と、育成ユニット背面壁１２ｂの背面スリット状開口２０とは完全に重なって全開（開口率１００％）の状態とされる。この状態から、育成ユニットの扉１８を閉めると、スプリング５３の戻りにより開口率調整板２１は図の左側に引っ張られて図８に図示した全閉（開口率０％）の状態まで戻される。 That is, FIG. 8 shows a state in which the door 18 of the growing unit is closed, and the aperture ratio adjusting plate 21 is pulled to the left side of the drawing by the spring 53, and the slit-shaped opening 22 of the aperture ratio adjusting plate 21 is In this state, the rear slit-like opening 20 of the rear wall 12b of the growing unit is not completely overlapped (opening ratio 0%).
FIG. 9 shows a state in which the door 18 of the growing unit is opened. As the door 18 opens, the wire 52 is pulled in the direction of the arrow while rotating the two rollers 50, 51, and the aperture ratio adjusting plate 21. Slide to the right side of the figure. At this time, the spring 53 is extended to the right side (arrow direction) in the drawing, and the slit-like opening 22 of the aperture ratio adjusting plate 21 and the rear-side slit-like opening 20 of the rear face rear wall 12b are completely overlapped to be fully opened (opening). Rate 100%). When the door 18 of the growing unit is closed from this state, the opening ratio adjusting plate 21 is pulled to the left side of the drawing by the return of the spring 53 and returned to the fully closed state (opening ratio 0%) shown in FIG.

上述した本発明による植物育成ユニット１０は、複数段の棚板を備えた育成棚の各段に載置し、この育成棚を閉鎖型構造物内に配置することにより、図１０に図示したと同様の多段式の植物育成装置とすることもできる。
かような多段式育成装置とすることにより、閉鎖型構造物６０内の空調装置６５により調温調湿され、炭酸ガス施用装置６６により炭酸ガス濃度が調整された雰囲気が、育成棚６１各段に設けたファン６４で各段毎に空気流となって流通することになる。その結果、各段に載置した育成ユニットを開状態とした場合には、温湿度および炭酸ガスが調整された空気流が育成ユニット内部を扉１８側から背面側へ流れ、人工照明装置６３による適切な人工照明の下で効果的な育苗がなされる。
一方、各段に載置した育成ユニットを閉状態とした場合には、育成ユニットの扉１８両側の側壁１２ｃ、１２ｄに設けた複数の通気孔２４に沿って育成ユニット外部を流れる空気流によって静圧が生じ、比較的小さい通気孔２４であっても、炭酸ガス含有雰囲気の空気流と育成ユニット内とのガス交換が効果的になされ、育成ユニット内の加湿状態を損なわずに炭酸ガスを補充することができる。 The plant growing unit 10 according to the present invention described above is illustrated in FIG. 10 by being placed on each stage of a growing shelf having a plurality of stages of shelves and arranging the growing shelf in a closed structure. A similar multi-stage plant growing apparatus may be used.
By adopting such a multi-stage growth apparatus, the atmosphere in which the temperature is controlled by the air conditioner 65 in the closed structure 60 and the carbon dioxide concentration is adjusted by the carbon dioxide application apparatus 66 is provided in each stage of the growth shelf 61. The fan 64 provided in the circulates as an air flow for each stage. As a result, when the growing unit placed on each stage is in an open state, an air flow adjusted in temperature and humidity and carbon dioxide flows from the door 18 side to the back side inside the growing unit, and the artificial lighting device 63 Effective seedlings are made under appropriate artificial lighting.
On the other hand, when the growing unit placed on each stage is in a closed state, static air flows through the outside of the growing unit along the plurality of vent holes 24 provided on the side walls 12c and 12d on both sides of the door 18 of the growing unit. Even if the pressure is generated and the air hole 24 is relatively small, gas exchange between the air flow in the carbon dioxide-containing atmosphere and the inside of the growing unit is effectively performed, and carbon dioxide is replenished without impairing the humidified state in the growing unit. can do.

育成棚６１各段に載置した育成ユニットに流通させる空気流の風量は、植物の育成過程により適宜調節することが望ましい。例えば接ぎ木苗の育苗を例に挙げて説明すると、育成ユニットの扉１８と背面スリット状開口２０を開状態として台木および穂木を育苗するに際しては、子葉が完全展開するまでは育成ユニットを流れる風量を少なくし、子葉が展開した後には風量を最大にする。また、育成ユニットの扉１８と背面スリット状開口２０を閉状態として接ぎ木苗を養生するに際しては、接ぎ木接合部が融合するまで育成ユニットに空気流を流す必要はない。このように、育成ユニットに流す空気流の風量を調節するには、育成ユニットの扉１８の開き程度や背面スリット状開口２０の開口率を調節することにより行うことができるが、育成棚６１各段に設けたファン６４に印加する電圧を変動させてファンの回転数を変化させ、育成棚各段に流す風量を調節することにより行うこともできる。   It is desirable that the air volume of the air flow to be circulated through the growing units placed on each stage of the growing shelf 61 is appropriately adjusted according to the plant growing process. For example, in the case of raising grafted seedlings as an example, when raising rootstocks and ears with the door 18 and rear slit-like opening 20 of the growing unit in an open state, the growing unit flows until the cotyledons are fully deployed. Reduce air volume and maximize air volume after cotyledons are deployed. Further, when the grafted seedling is cured with the door 18 and the rear slit-like opening 20 of the growing unit closed, it is not necessary to flow an air flow through the growing unit until the grafted joint is fused. As described above, the air volume flowing through the growing unit can be adjusted by adjusting the degree of opening of the door 18 of the growing unit and the opening ratio of the rear slit-shaped opening 20. It can also be performed by changing the voltage applied to the fan 64 provided in the stage to change the rotation speed of the fan and adjusting the amount of air flowing through each stage of the growth shelf.

以上の説明では、本発明の植物育成ユニットおよびこの育成ユニットを用いた多段式植物育成装置を接ぎ木苗の育成に使用する場合について説明したが、好光性種子や栄養繁殖系植物の育成、組織培養苗の順化などにも効果的に使用することができる。
すなわち、トルコギキョウ、ペチュニア、プリムラなどの好光性種子の慣行的な発芽、育成方法は、種子に少量の覆土を施し、表土が乾燥しないように水をスプレーしたり底面かん水を行っていた。本発明の育成ユニットを使用する場合には、セルトレイの各セルに播種し、閉状態とした育成ユニットに入れて人工照明の下、温湿度及び炭酸ガス濃度を調整した雰囲気で高湿度（８５〜９５％）を維持することにより表土を乾燥しにくくする。発芽後も閉状態とした育成ユニット内で人工照明下、温湿度及び炭酸ガス濃度を調整した雰囲気で高湿度を維持することにより、子葉がしおれることがなく、光合成促進効果もあるため、良好に生育させることができる。 In the above description, the case of using the plant growing unit of the present invention and the multi-stage plant growing apparatus using this growing unit for growing grafted seedlings has been explained. It can also be used effectively for acclimatization of cultured seedlings.
In other words, the conventional germination and growth method for euphotic seeds such as Eustoma grandiflorum, petunia and primula involves applying a small amount of soil covering to the seeds and spraying water or watering the bottom so that the topsoil does not dry. When using the growth unit of the present invention, the cells are sown in each cell of the cell tray, placed in the closed growth unit, and placed under a high humidity (85 to 85) in an atmosphere with adjusted temperature and humidity and carbon dioxide concentration under artificial lighting. 95%) makes it difficult to dry the topsoil. Maintaining high humidity in an atmosphere where the temperature and humidity and carbon dioxide concentration are adjusted under artificial lighting in a closed growth unit after germination, the cotyledons are not wilted, and there is an effect of promoting photosynthesis. Can be grown.

栄養繁殖系植物の育成は、根、茎、葉などの栄養器官を種苗として用いるものであり、例えばキクやサツマイモなどが挙げられる。慣行的な方法では、培地に移植した栄養器官が発根するまで、ハウスあるいは冷蔵庫中で弱光下、高湿度（１００％）環境に維持する方法が採用されていた。本発明の育成ユニットを使用する場合には、閉状態とした育成ユニット内で、適切な光強度の人工照明下、温湿度及び炭酸ガス濃度を調整した雰囲気で一定の高湿度（８５〜９５％）を維持することにより発根が効果的になされ、生育も早く、苗のロス率を低減させることができる。   The vegetative breeding plant is grown by using nutrient organs such as roots, stems and leaves as seedlings, such as chrysanthemum and sweet potato. In the conventional method, a method of maintaining a high humidity (100%) environment in a house or a refrigerator under low light until the vegetative organ transplanted to the medium is rooted has been adopted. When the growth unit of the present invention is used, a constant high humidity (85 to 95%) in an atmosphere in which the temperature and humidity and the carbon dioxide gas concentration are adjusted under artificial lighting with an appropriate light intensity in the closed growth unit. ) Is effectively rooted, grows quickly, and can reduce the loss rate of seedlings.

また、組織培養苗の順化は、例えばサツマイモやアルストロメリアなどの培養苗の順化が挙げられ、慣行的な方法としては、培地に移植した組織培養苗をハウス内で遮光下に加湿して行う方法が採用されていた。本発明に育成ユニットを使用する場合には、閉状態とした育成ユニット内で適切な光強度の人工照明下、温湿度及び炭酸ガス濃度を調整した雰囲気により順化環境のきめ細かい制御が可能となるため、慣行方法に比べるとロス率を低減させることができる。   In addition, acclimatization of tissue culture seedlings includes, for example, acclimatization of cultured seedlings such as sweet potato and alstroemeria. As a conventional method, tissue culture seedlings transplanted to a medium are humidified in a house under light shielding. The method was adopted. When the growth unit is used in the present invention, the acclimatization environment can be finely controlled by adjusting the temperature and humidity and the carbon dioxide concentration under artificial lighting with appropriate light intensity in the closed growth unit. Therefore, the loss rate can be reduced as compared with the conventional method.
