【発明の詳細な説明】
本発明は花芽のないイチゴ苗（第−次苗と仮称）を効率
的に花芽分化促進させる水耕栽培に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to hydroponic cultivation for efficiently promoting flower bud differentiation of strawberry seedlings without flower buds (tentative name: secondary seedlings).
＝発明の目的＝ 〔産業上の利用分野〕 本発明はイチゴの栽培分野に係る。=Purpose of the invention= [Industrial application field] The present invention relates to the field of strawberry cultivation.
従来、作物の花芽分化を促進させる方法としては、人為
的に栽培環境（主に空気環境）の温度を調節したり、シ
ェードの開閉又は電照により日長時間を調節する方法が
とられてきた。Conventionally, methods for promoting flower bud differentiation in crops have been to artificially adjust the temperature of the cultivation environment (mainly the air environment), or to adjust day length by opening/closing shades or lighting. .
たとえばイチゴの場合、花芽分化するためには、１４℃
以下のイチゴ苗全体を環境にさらされるか、短日、苗の
持つチッソレベルを低下させるのが条件のため、自然条
件下では夏期などの時節に花芽分化を行うことができな
かった。For example, in the case of strawberries, in order to differentiate into flower buds, the temperature must be 14℃.
Under natural conditions, flower bud differentiation was not possible during seasons such as summer, as the strawberry seedlings below were either exposed to the environment as a whole, or the days were short, or the nitrogen levels in the seedlings were reduced.
また、人為的に花芽分化を行う方法としては、夏期高山
に苗を移動させる 山あげ′ とか、あるいはイチゴ苗
を葉を含めて苗全体を冷蔵庫に収容して冷却するとか、
あるいは冷水、冷空気で葉を含めてイチゴ苗全体を処理
していたため、特別な装置をもつハウス内等で栽培する
必要があった。In addition, methods for artificially differentiating flower buds include moving the seedlings to high mountains in the summer (mountain-ageing), or storing the entire strawberry seedlings including the leaves in a refrigerator to cool them.
Alternatively, since the entire strawberry seedling, including the leaves, was treated with cold water and air, it was necessary to grow it in a greenhouse with special equipment.
従来の方法では、苗全体を対象に空調機により空気環境
を調節したり、シェードの開閉を行うことにより日長調
節を行ってきた。そのため空調機の設置やシェードのた
めの設備費が多大であり、環境調節するための維持費も
多大であった。In conventional methods, day length has been adjusted by controlling the air environment for the entire seedling using an air conditioner or by opening and closing shades. Therefore, the equipment costs for installing air conditioners and shades were large, and the maintenance costs for controlling the environment were also large.

〔課題をを解決するための手段〕
本発明は、イチゴのクラウン部分のみを対象として花芽
分化に適する温度に冷却すれば花芽分化が行われること
を研究の結果発見したことに基づくものである。=Structure of the invention= [Means for solving the problem] The present invention is based on the discovery as a result of research that flower bud differentiation occurs if only the crown part of a strawberry is cooled to a temperature suitable for flower bud differentiation. It is based on
第１図の１は掘り起こした花芽の無いイチゴ苗（第−次
苗と仮称する）であって、２はその葉、３はクラウン、
４は根である。In Figure 1, 1 is a strawberry seedling without flower buds that has been dug up (tentatively referred to as a primary seedling), 2 is its leaves, 3 is the crown,
4 is the root.
第２図はこの第−次苗を１列に１０〜１５本程度水耕栽

。FIG. 2 shows that 10 to 15 of these primary seedlings are planted densely in one row on a seedling head 5 with about 70 markings for hydroponic cultivation, and the crown part is heated to approximately 100 mL by using a cooling chiller unit 8 and a thermostat 9. FIG. 2 is an explanatory system diagram of an apparatus according to an embodiment of the present invention that circulates and supplies cold water 6 controlled at ~15°C.
図において７は冷水タンク、Ｃはコック、Ｐはポンプ、
１０は配管である。このようにしてイチゴの第−次苗の
クラウン部分を約１０〜１５℃の冷水で約２０日間冷却
すると花芽分化が起こる。In the figure, 7 is a cold water tank, C is a cock, P is a pump,
10 is piping. When the crown portion of the primary strawberry seedling is cooled in cold water at about 10 to 15° C. for about 20 days, flower bud differentiation occurs.
花芽分化した苗（第二次苗と仮称する）は栽培用ベット
に移植（定植）して栽培する。Seedlings that have differentiated flower buds (tentatively named secondary seedlings) are transplanted (planted) into cultivation beds and cultivated.
本発明はイチゴを実施例としたが、イチゴと同様の根茎
を有する苗の花芽促進にも応用できる。Although the present invention uses strawberries as an example, it can also be applied to the promotion of flower buds in seedlings having rhizomes similar to those of strawberries.
＝発明の効果＝
花芽分化は苗のクラウン部分のみを対象として約ｌＯ〜
１５℃に冷却すれば良いので、従来のように、葉を含め
た苗全体の冷却栽培方法に比べて空気環境の温度管理を
必要としない。そして、夏季に高山の寒冷地に持ち運び
する必要もなく、また冷蔵庫内の狭いスペース内で行う
必要もないので、効率良く花芽分化促進のための栽培が
できる。= Effect of the invention = Flower bud differentiation targets only the crown part of seedlings and is approximately 10~
Since it is only necessary to cool the seedling to 15°C, there is no need to control the temperature of the air environment compared to the conventional method of cooling the entire seedling including the leaves. Furthermore, there is no need to carry the plant to the cold region of high mountains during the summer, or to carry out cultivation in a narrow space inside a refrigerator, so cultivation for promoting flower bud differentiation can be carried out efficiently.
