どめることが好ましい。In the hydroponic cultivation apparatus according to the present invention configured as described above, seeds of plants to be cultivated are sown in water-retaining urethane, the germinated seeds are carried in the through holes of the cultivation boat 2, and the roots of the plants are Until it grows to a certain extent, the water level of the nutrient solution 11 in the cultivation tank 1 is adjusted to a higher level using the water level adjustment pipe 10, and the cultivation board is placed on the water surface as shown in FIG. 6(B)]
Make sure to support 2. In this way, by placing the cultivation board 12 on the nutrient solution 11, it is possible to prevent the roots of the plants from being damaged by contact with other objects. In this case, the cultivation tank 1 is preferably kept horizontally, and the horizontal gutter-like members 2 forming the cultivation tank 1 are preferably connected at a length of about 4 m.
これは、それ以上の連接をすると養液11の表面が栽培
ボード12によって覆われ空気との接触面積か小さい為
、養液中の溶存酸素が末端にて不足する可能性があるか
らである。This is because if more connections are made, the surface of the nutrient solution 11 will be covered by the cultivation board 12 and the contact area with the air will be small, which may result in a shortage of dissolved oxygen in the nutrient solution at the end.
上述の様にして、根がある程度成長するのを待ち、栽培

て再び栽培槽1に供給されることが好ましい。Wait for the roots to grow to a certain extent as described above, lower the water level of the nutrient solution 11 in the cultivation tank 1, and place the cultivation board 12 on the inner bottom of the cultivation tank 1 as shown in FIG. 6(A). Make sure to support it. In this case, the cultivation tank 1 is constructed by a suitable means (not shown), such as changing the height of a support installed on the ground, from one end where the nutrient solution is supplied to the other end where the nutrient solution is discharged.
It is inclined at a downward slope of about 60 degrees to promote the flow of the nutrient solution 11. The nutrient solution is first evenly supplied to the grooves 3c of the first water stop board 3, and then evenly supplied from the grooves 30 to the grooves 2e of the horizontal gutter-like member 2 and distributed. The nutrient solution flowing in the groove 2e is the groove 2.
The liquid passes around the roots growing in the area e, reaches the second water stop board 5, is collected by the groove 5b, and drained through the drain hole 5C. It is preferable that the drained nutrient solution is recovered and supplied to the cultivation tank 1 again via the nutrient solution supply means.
なお、上述した様に、水位を下げて溝2e内に養液を流
通させた場合、根が成長して密集した溝2eでは密集し

より一旦せき止められた後、堰2fを越えて金欠2Cの
上部に形成された溝に流れ込み、この溝から谷溝2eに
均等に流れ込むようになっている。As mentioned above, when the water level is lowered and the nutrient solution is distributed in the groove 2e, the nutrient solution is blocked by the dense roots in the groove 2e where the roots have grown and become densely packed, and the nutrient solution on the downstream side of the groove 2e is blocked. In the hydroponic cultivation apparatus according to the present invention, the weir 2f is formed in the groove 2e on the inner bottom surface of the horizontal gutter-like member 2, as described above, in order to avoid the possibility that the flow rate of the nutrient solution is insufficient compared to other grooves. Therefore, the nutrient solution flowing through the groove 2e is once stopped by the weir 2f, and then flows over the weir 2f into the groove formed at the top of the gold hole 2C, and is evenly distributed from this groove to the valley groove 2e. It's supposed to flow into it.
また、養液を溝2e内に流通させる場合には、養液と栽
培ボード12との間に空気槽が形成されているので、空
気中の酸素が養液に溶は込むことが可能である。よって
、横樋状部材2を多数連設しても養液中の溶存酸素量か
、末端にて不足することかない。Furthermore, when the nutrient solution is distributed in the groove 2e, since an air tank is formed between the nutrient solution and the cultivation board 12, oxygen in the air can dissolve into the nutrient solution. . Therefore, even if a large number of gutter-like members 2 are installed in series, the amount of dissolved oxygen in the nutrient solution will not be insufficient at the end.

とがない。In addition, since the internal bottom of the cultivation tank has a triangular wave shape, the roots of the plants grow three-dimensionally with appropriate gaps through which the nutrient solution can flow. The raised protrusions 12b form a gap in which roots can grow between the convex part on the inner bottom of the cultivation tank 1 and the lower surface of the cultivation board 12, and the growth of roots that try to cross the convex part is not hindered. .

A nutrient solution discharge means that can freely adjust the water level of the nutrient solution is provided at the other end of the cultivation tank to which the nutrient solution is supplied from one end by the nutrient solution supply means, and a plurality of through holes support a water holding part for holding plants. A floating cultivation board is housed in the cultivation tank so that it can move up and down, and a plurality of grooves are formed on the internal bottom of the cultivation tank, extending from one end of the cultivation tank to the other. The method of supplying the nutrient solution can be changed according to the growth of the roots, making it possible to efficiently replace the nutrient solution around the roots, and the grown roots grow in a three-dimensional manner with appropriate gaps. Therefore, simply by circulating the nutrient solution around the roots, the nutrient solution around the roots can be replaced smoothly, improving harvest efficiency.
また、栽培槽の内部底面に栽培槽の一端部から他端部ま
て延在した複数条の溝と交叉する溝及び突条を形成して
