<栽培スケジュール>
次に、図2を用いて、苗木P1を栽培する年間スケジュールについて説明する。本実施形態においては、2月21日から10月31日までを生育期とする。なお、通常の露地栽培では、4月から8月が生育期である。
<Cropping schedule>
Next, an annual schedule for cultivating the seedlings P1 will be described using FIG. In this embodiment, the growing season is from February 21 to October 31. In ordinary open-field cultivation, the growing season is from April to August.

生育期において苗木P1が最もよく生育する最生育期(4月1日〜10月31日)においては、日長時間を16時間、気温の設定温度を25℃、培養液の設定温度を15℃〜20℃、CO2濃度の設定濃度を1000ppmとして生育する。   In the highest growth stage (April 1st-October 31st) at which the seedlings P1 grow the most during the growing season, set the temperature of the air temperature to 25 ° C and the temperature of the culture solution to 15 ° C for 16 hours a day long. Grow at ~ 20 ° C, set concentration of CO 2 concentration as 1000 ppm.

In this dormancy induction period, the setting time of the culture solution is changed to 10 ° C., and the setting temperature is 23 ° C., and the setting temperature is 23 ° C. for 8 hours. In this case, the CO 2 supply control unit 54 of the control unit 50 closes the valve 33 of the carbon dioxide gas supply unit 30 to stop the exhaust from the office 31. When the supply from the carbon dioxide gas supply unit 30 is stopped, the carbon dioxide concentration in the plant cultivation facility 10 is about 200 ppm.

その後、12月1日に休眠打破を開始する。この休眠打破期においては、日長時間を8時間、二酸化炭素の供給を停止で、設定気温を7℃、培養液の設定温度を3℃に設定変更する。   Then, on December 1st, we will start sleeping break. In this dormancy break period, the setting temperature is changed to 7 ° C. and the setting temperature of the culture solution is changed to 3 ° C. by stopping the supply of carbon dioxide for 8 hours a day long time.

休眠打破を開始した1500時間以上の期間が経過し、生育期の2週間程前の2月5日になった場合、冬芽生育期に移行する。この冬芽生育期においては、気温と培養液の温度を段階的に上昇させる。具体的には、冬芽生育期の開始日(2月5日)から冬芽が十分に生育する(3月31日)までの約40日間、植物栽培施設10内の気温を23℃、培養液の液温を10℃に設定する。なお、この冬芽生育期の途中において、休眠打破を開始してから2000時間が経過して生育期になった場合には、16時間日長に変更し、二酸化炭素を供給する。
