In the hydroponic cultivation device (10) shown in the drawing, an annular hydroponic bed (11A, 11B, 11C, 11D) is used. The hydroponic beds are superposed at a predetermined interval, and the diameter of the hydroponic beds gradually increases from the top to the bottom. That is, the diameter of hydroponics bed is bed (11A)
<Bed (11B) <Bed (11C) <Bed (11D) Each hydroponics bed (11A, 11B, 11C, 1
As shown in Fig. 2, 1D) is an annular water tank (1
2) and a perforated panel (13) placed on the water tank (12), and a water absorber (15) in which a plant P is planted in the hole (14) of the perforated panel (13). Has been inserted. The water tank (12) of each hydroponic bed (11A, 11B, 11C, 11D) is a motor (1) installed in the base (16) as shown in FIGS. 3 and 4.
Pulley (18), belt (19) and pulley (2)
Hollow rotating shaft (21) that can be rotated via (0)
Supported via (22).

As shown in FIG. 4, a nutrient solution tank (23) is installed in the base (16), and a nutrient solution supply passage (24) is extended from the nutrient solution tank (23) so that the nutrient solution is supplied to the nutrient solution tank (23). The liquid supply path (24) is connected to the nutrient solution pump (2
5), introduced into the hollow rotary shaft (21) through the chiller (26) from the uppermost hollow branch rod (22) to the uppermost hydroponics bed (11A)
Contact. A rotary joint (24A) is interposed in the nutrient solution supply path (24) at the lower end inlet of the hollow rotary shaft (21). Connecting path (27) from the hydroponics bed (11A) at the top
The connecting path (27) is the uppermost hollow branch rod (22), the hollow rotating shaft (21), the second stage hollow branch rod (22) via the second stage hydroponics bed ( 11B), and similarly, the second and third hydroponics beds (11B, 11C) and the third and bottom hydroponics beds (11C, 11D) are also connected (27). Have been contacted by. And the bottom hydroponics bed (11D)
A drainage channel (28) is extended from the drainage channel (28), and the drainage channel (28) communicates with the nutrient solution tank (23).

A fertilizer stock solution tank (29) is further provided in the base (16).
The fertilizer stock solution tank (29) and the nutrient solution tank (23) are installed
Are connected to each other by a stock solution supply passage (31) with a stock solution pump (30) interposed therebetween. The stock solution pump (30) is inserted into a nutrient solution tank (23), and a pH meter (32) and an EC meter (33) are provided. )
The operation is controlled by.

The hydroponic cultivation device (10) is housed in a transparent container (34) as shown in FIG. 1, and a lamp (35) is attached to the ceiling of the transparent container (34), for example, a department store or a bank. If it is installed in a station or the like, the color and shape of the plant P cultivated by the hydroponic cultivation device (10) can be enjoyed from the transparent container (34). Since the plant P is three-dimensionally cultivated, the interior decoration effect is great. If the rotating shaft (21) is rotated by the motor (17), it will be more interesting as a moving interior decoration. If rice, vegetables, etc. are selected as the plant P, rice and vegetables can be provided as gifts, gifts, etc. after harvesting. Furthermore, if an herb is selected as the plant P, the hydroponic culture vessel (1
It can provide the scent of herbs around (0). In this case, the transparent container (34) is provided with ventilation holes, and the container (34)
Air may be blown into the air and blown out from the ventilation hole.

In the hydroponics device (10), a nutrient solution pump is used.
(25) is activated to adjust the temperature of the nutrient solution from the nutrient solution tank (23) by the chiller (26), and the nutrient solution is supplied to the uppermost hydroponics bed (11A) through the nutrient solution supply channel (24). Liquid, and then the lower hydroponics bed (11B, 1B) via the connection (27).
1C, 11D) to supply the nutrient solution sequentially, and the nutrient solution tank (23) from the lowermost hydroponic bed (11D) through the drainage channel (28)
Return to. The pH and electric conductivity (EC) of the nutrient solution in the nutrient solution tank (23) are measured by the pH meter (32) and the EC meter (33).
(30) is activated and fertilizer concentrate tank (29) to concentrate supply channel (31)
The fertilizer stock solution is supplied into the nutrient solution tank (23) via the.

The plant P cultivated by the hydroponic culture vessel (10) in this manner is supplied with nutrient solution and irradiated with light from the lamp (35) to grow.
The diameter of (A, 11B, 11C, 11D) gradually increases from the top to the bottom, so that the light of the lamp (35) is sufficiently supplied to the hydroponic beds (11A, 11B, 11C, 11D) of each stage. . Further, even if the plant P grows and grows, it is not interfered by the upper hydroponics bed. As described above, each hydroponic bed (11
The rotation of A, 11B, 11C, 11D) actively updates the air around the plant P, which has a good effect on the growth of the plant P.
