取り付けて噴出散布するようにしてもよい。The illustrated embodiment will be described below. 1.2 is a ceramic cylinder, which is made by mixing 4 to 8% of siliceous ceramic porous material as a moisture absorbing material in clay clay, or by mixing about 10% of dry coconut husk fiber in clay clay as a moisture absorbing material. 0.8 to 1.2
% mixed and fired at 750 to 850°C. The ceramic cylinders 1 and 2 are made of the same material as described above, and are formed by applying a watertight surface layer to the outer peripheral surface by glazing, etc. They are common in that they have the same diameter and have expanded outer circumferential flanges 5.6 in series. In addition, the above-mentioned material of the ceramic cylinders 1 and 2, except for the above-mentioned watertight surface layer, is capable of penetrating and exuding a hydroponic solution,
This is important in the present invention. However, whereas the ceramic cylindrical body 1 is tall and has a plurality of downward recessed notches 7 at the lower end of its peripheral wall at required intervals, the ceramic cylindrical body 2 is short and has recessed notches 7 extending at the lower end of its peripheral wall. has not been established. Reference numeral 8 denotes a lid whose material and diameter are the same as those of the ceramic cylindrical body 1゜2.A circular hole 10 is formed in the center of the top plate 9, and a downward recess 11 is formed in the lower end of the peripheral wall as required. They are set at intervals. 12 is a base, 13 is a liquid receiver mounted on it, and 14 is a container.
The liquid receiver has upper openings 13' and 14' in the container 13.
The rotary table 14 is rotatably mounted on the base 12 in a state in which the two are fitted together. It is rotatably supported on a base 12 by supported wheels 16. The rotary table 14 has a gear 17 on its outer circumferential surface, and the motor 1
A worm gear 20 of a drive shaft 19 rotated by 8 is meshed with the gear 17. Therefore, the rotary table 14 can rotate as the drive shaft 19 rotates. The ceramic cylindrical body 2 is mounted on the rotary table 14 with the outer circumferential flange 6 facing upward, and a plurality of ceramic cylindrical bodies 1 are also stacked one after another with the outer periphery flange 5 facing upward, and A lid body 8 is mounted on the uppermost ceramic cylinder 1, thereby forming rotating cultivation towers a and a'. The worm gears 20 are located at the tip and center of the drive shaft 19, and the one on the tip side is connected to the rotating cultivation tower a, and the one on the center side is connected to the rotating cultivation tower a'. The rotating culture bases a and a' are in a relationship in which they are simultaneously rotated in the same direction by a motor 1B. Reference numeral 21 denotes a liquid distribution pipe that is connected to a hydroponic liquid tank (not shown) via a flow rate control valve and supplies the hydroponic liquid by a pump;
The branch pipes 22 and 23 are inserted into the lid 8 through the circular hole 10, and the hydroponic liquid is sprayed onto the inner surface of the peripheral wall of the lid 8 from a nozzle 24 at the inner end. The hydroponic liquid sprayed and sprayed on the inner surface of the circumferential wall of the lid body 8 flows down along the inner surface of the circumferential wall and the inner surface of the circumferential wall of the stacked ceramic cylinders 1, and also permeates and oozes into the materials of these materials. , a part of the ceramic cylinders 1 and 2 are attached to the flat part 3.4 surrounded by the outer peripheral collar 56,
It penetrates through the downwardly directed recess 11.7 or seeps out of the material of the surrounding wall, so that the upper surface of the flat part 3.4 is kept at least moist with the hydroponic liquid at all times. The hydroponic liquid that has flowed down as described above is transferred to the upper surface opening 13',
14', the liquid receiver is stored in the container 13, and when the stored hydroponic liquid reaches a predetermined liquid level or higher, the liquid is returned to the liquid return port pipe 2.
5 and is returned to the hydroponic liquid tank by a liquid return pipe 26. This liquid return pipe 26 penetrates the base 12 of the rotary cultivation tower a',
The tip thereof is inserted into the base 12 of the rotating cultivation tower a, and the liquid return port pipe 25 that stands up between the tip and the middle is connected to the rotating cultivation tower a.
The liquid receiver inside a' projects into the container 13. The liquid receiver 27 is a support that stands between the center of the bottom surface of the container 13 and the inner end of the branch pipe 22.
23 rotates together with the rotating cultivation towers a and a' without any problem. For cultivating plants using the device configured as described above, the flat parts 3 and 4 surrounded by the outer peripheral flanges 5 and 6 of the ceramic cylinder 1.2 are
By sowing seeds or placing bulbs of the plant, supporting and planting the seedlings grown in the desired seedbed with appropriate means, and spraying the hydroponic solution from the nozzle 24 as described above, the plant can be grown. The hydroponic solution is allowed to permeate and exude into the flat portion 3.4, and the upper surface of the flat portion 3.4 is kept at least in a wet state at all times. As a result, the plant germinates and grows, and the above-mentioned flat part 3
．． 4, and extend the roots downward into the concave notch 11,
7 and extends to the inner surface of the peripheral wall of the ceramic cylinder 1.2. Thereafter, according to the growth of the plant, the amount of sprayed hydroponic solution is adjusted as appropriate, and conventional cultivation management is performed. In the above, the rotary cultivation towers a and a' are rotated constantly or intermittently by the motor 18 via the drive shaft 19, so that the plants being cultivated around the rotary cultivation towers a and a' are uniformly exposed to sunlight. The plants are then allowed to grow in a uniform state. Since the ceramic cylindrical body 1.2 is formed with a watertight surface layer on its outer peripheral surface by applying a glaze or the like, at least the hydroponic liquid does not evaporate through the outer peripheral surface. Harvesting a cultivated plant can be easily done by grasping the stem and simply pulling. This is a rotary cultivation tower a,
This is because it can be easily peeled off from the inner surface of a', and this is because the rotary cultivation towers a and a' are made of the ceramic cylinder 1.2 having the above composition. In the above embodiment, two rotary cultivation towers are installed in series, but it is of course possible to install more than that, or on the contrary, each tower may be installed individually. To supply the liquid, for example, a liquid distribution pipe may be inserted into each rotary cultivation tower from the base and placed in an upright position, and a required nozzle may be attached to the upper end of the pipe for spraying.
