  Next, another embodiment will be described based on FIGS. In this embodiment, when cultivating strawberries with the nutrient solution cultivating apparatus provided in the greenhouse 51, the nutrient solution is supplied to the cultivation bed 35 by the liquid supply hose 36 every predetermined time, and when the supply of the nutrient solution is completed, The nutrient solution remaining in the liquid supply hose 36 is collected in the drainage tank 62 to prevent the temperature of the nutrient solution in the liquid supply hose 36 from rising and to prevent the growth failure of the strawberry.

  Inside the greenhouse 51, the support means 52 supports the cocoon-shaped cultivation frame 33 with a gentle downward inclination (for example, an inclination of 1/500 or more) in the longitudinal direction, and a waterproof sheet (not shown) is provided on the cultivation frame 33. A bed made of rock wool (not shown) is placed on the bed, and left and right liquid supply hoses 36 and 36 are arranged along the front and rear direction of the bed (not shown). The part 54 is mounted and the hydroponic cultivation apparatus is comprised.

  Further, a nutrient solution supply device 56 provided with a controller 57 is provided, and a predetermined amount of nutrient solution is supplied to one side of the liquid supply hose 36,... At a predetermined time while being controlled by the controller 57 from a nutrient solution supply pump 58. While feeding to the other side, the nutrient solution is sprayed on the cultivation bed 54 of the strawberry P,... And the bed, and the feed solution sent to the other side of the feed hose 36,. 64 is collected. When the drive of the pump 58 is stopped and the supply of the nutrient solution is stopped, the solenoid 61a is activated for a predetermined time (for example, 3 to 5 minutes) by a command from the controller 57, and the valve 61 of the liquid supply recovery pipe 59 is operated. Is adjusted to open, and the nutrient solution is collected in the drainage tank 62.

Further, as shown in FIG. 15, the nutrient solution collected in the drainage tank 62 is sent to the sterilization tank 64 by the pump 63 to be sterilized, and is sent again to the nutrient solution supply device 56. In addition, when the temperature of the nutrient solution sent from the sterilization tank 64 is high, the flow path of the pump 58 is switched and sent again to the drainage tank 62 via the circulation pipe 67 buried in the ground. It is. The drainage tank 62 is provided with a water level sensor 68, and excess drainage is overflowed and discharged. Also, as shown in FIG. 14, the nutrient solution from the pump 58 to the liquid supply hoses 36,.

  Moreover, you may comprise as FIG. When a nutrient solution supply start command is issued from the controller 57 (step S11), the valve 61 is adjusted to open (step S12), and then the nutrient solution supply pump 58 is driven (step S13). Then, the pump 58 is driven to start supplying the nutrient solution. However, since the valve 61 is adjusted to be opened, the water pressure of the solution supply hose 36 is low, and the remaining nutrient solution is not supplied to the strawberry. It is collected in the drainage tank 62.

  Subsequently, the water temperature of the recovered nutrient solution is detected by the water temperature sensor 69 provided on the terminal side of the feed solution recovery pipe 59, and it is determined whether or not the water temperature is equal to or lower than a predetermined temperature (for example, raw water temperature +10 degrees C) (step S14). If the answer is No, the process returns to step S13. If the answer is Yes, the valve 61 is closed (step S15). Next, the fertilizer valve (not shown) provided in the fertilizer tank (not shown) is adjusted to open, the fertilizer is supplied to the nutrient solution supply device 56 (step S16), and the supply of the nutrient solution is started. Then, the water pressure of the liquid supply hose 36 rises and spraying of nutrient solution to the strawberry is started (step S17).

According to the said structure, spraying of the high temperature nutrient solution at the time of the supply start of a nutrient solution can be prevented, and the high temperature growth disorder | damage | failure of a strawberry can be prevented.
