The water containing nutrients is supplied to the plurality of hydroponic cultivation devices 21 by the circulation pump 27 described above. In addition, the density | concentration of the liquid fertilizer supplied from the liquid fertilizer tank 25 to the hydroponic cultivation apparatus 21, a supply amount, a supply time, etc. are automatically adjusted by the control conditions set according to the kind, growth condition, etc. of the plant to be cultivated. The

  Moreover, the gas cylinder 23 which is an air supply means is arrange | positioned out of the containers 11-17, and the carbon dioxide gas (carbon dioxide) stored in the gas cylinder 23 goes into the containers 12-16 via the gas piping 24. The supply timing, supply amount, and the like are automatically adjusted according to the carbon dioxide concentration in the containers 12-16.

  As shown in FIGS. 2 to 5, in the containers 12 to 16, a plurality of stages of shelf boards 53 are provided across the respective longitudinal passages 54, and the hydroponic cultivation apparatus 21 is provided on each shelf board 53. Are arranged, and a plurality of light emitters 49 are arranged on the lower surface of the shelf 53 (or above the hydroponic cultivation apparatus 21). The light emitter 49 uses a fluorescent lamp, but is not limited to this, and an LED light emitter or a planar light emitter can also be used.

  On the back side of the shelf 53 holding the hydroponic cultivation device 21 (opposite side of the passage 54), a blowing means 50 that circulates air in the containers 12 to 16 toward the hydroponic cultivation device 21 is provided. Is provided. The blower means 50 includes a fan 55 that sucks air in each of the containers 12 to 16, and a duct 57 with an air outlet 56 that sends the air sucked by the fan 55 toward the hydroponic cultivation device 21 on the shelf 53. I have.

  As shown in FIGS. 6 and 7, the hydroponic cultivation apparatus 21 includes a water tank 58 arranged on each shelf board 53, and a planting pallet 59 held in a state of floating in the water W in the water tank 58. It is equipped with. The planting pallet 59 is provided with a plurality of through holes 59a whose diameter is reduced downward, and plants P are planted in the respective through holes 59a. The planting pallet 59 is formed of foamed synthetic resin, but may be formed of other materials as long as it floats on the water W.

  The water tank 58 is arranged inside a plurality of surrounding members 60 and 61 disposed so as to surround the upper periphery of the shelf 53 in a ring shape, and the surrounding members 60 and 61 located at the edge of the shelf 53. A cross-section that holds the periphery of the water shielding sheet 63 to the surrounding members 60, 61, the reinforcing member 62 in the form of a standing frame, the water shielding sheet 63 laid on the top surface of the shelf 53 and the inside of the surrounding members 60, 61. And a C-shaped elastic locking member 64. As shown in FIG. 7, the surrounding members 60 and 61 include linear tubular rod members 60 a and 61 a arranged along the longitudinal direction of the shelf plate 53, and rod members 60 a and 61 a in the vicinity of the edge of the shelf plate 53. The connecting members 60b and 61b have a “smear” shape that connects the ends of the two.

  As described above, the cultivation facility 10 is arranged in the air conditioner 20 that adjusts the temperature and humidity in the containers 12 to 16, the gas cylinder 23 that supplies carbon dioxide gas into the containers 12 to 16, and the containers 12 to 16. In addition, since the water supply device 48 that supplies water including nutrients to the plurality of hydroponic cultivation devices 21 and the light emitter 49 that illuminates the inside of the containers 12 to 16 are provided, the efficiency is not affected by the weather and temperature. Plant P can be cultivated.

  Moreover, since the ventilation means 50 which circulates and blows the air in the containers 12-16 toward each of the some hydroponic cultivation apparatus 21 is provided, the growth failure resulting from the temperature difference in the containers 12-16 occurs. hard. Furthermore, since the planting pallet 59 of the hydroponic cultivation apparatus 21 is held in a state of floating in the water W in the water tank 58 on the shelf board 53, the horizontal movement is extremely easy.

  Therefore, as shown in FIG. 8, the rope 68 in which the tip 68 a is tied to the gripping tool 67 attached to the end of the planting pallet 59 located on the tip 58 a side of the water tank 58 is connected to the planting pallet 59. If it extends to the base end part 58b side of the water tank 58 in a state where it is submerged in the lower water W, the rope 68 is pulled each time the planting pallet 59 located on the base end part 58b side is taken out. The planting pallet 59 can be drawn toward the base end portion 58b. For this reason, for example, it is possible to perform the harvesting work while sequentially pulling the planting pallet 59 while the worker stays on the base end 58b side of the water tank 58 at the harvesting time and the like. Efficiency can be improved.

  In addition, when a new planting pallet 59 is set in the water tank 58 after the harvesting operation is finished and the planting pallet 59 is collected, it floats on the base end 58b side of the water tank 58, contrary to the above. The work can be performed while the planting pallet 59 is sequentially pushed out toward the tip 58a. For this reason, the setting work of the planting pallet 59 can also be performed while the worker stays on the base end 58b side of the water tank 58, which is effective in reducing the burden on the worker and improving the work efficiency.

  On the other hand, as shown in FIG. 9, an airtight member 66 having heat insulation and elasticity is interposed around the communication portion 65 provided between adjacent containers, for example, between the containers 12 and 13. Therefore, it is effective in maintaining the temperature, humidity, carbon dioxide concentration, etc. in the containers 12 to 16 at appropriate levels.

  Moreover, as shown in FIG. 1, in the cultivation facility 10, since the working room 17a is provided in the container 17, it is packed from the collection of the harvest from the hydroponic cultivation apparatus 21, without being influenced by the weather. Can be done. In addition, the cultivation facility 10 is an illustration and the cultivation apparatus of this invention is not limited to this.

  The cultivation facility of the present invention can be widely used as a facility for cultivating various plants such as vegetables and moss without being affected by the weather and temperature.
