して再び栽培槽１に供給されることが好ましい。In the hydroponic cultivation apparatus according to the present invention configured as described above, the roots grown to the extent that the roots protrude from the porous needles 15 are inserted into the through holes 2a of the cultivation board 12, and the cultivation tank 1 is placed on the ground. Installed at a downward slope of about 1/60 from one end where the nutrient solution is supplied to the other end where the nutrient solution is discharged by appropriate means (not shown) such as changing the height of the installed support. The distribution of the nutrient solution 11 is promoted. 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 3C to the grooves 2e of the horizontal gutter-like member 2 and distributed. The nutrient solution flowing in the groove 2e is the groove 2er.
J] The second water stop board 5 passes around the overgrown roots.
The water reaches the water, is collected by the groove 5b, and is 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.

むようになっている。As described above, when the nutrient solution is allowed to flow in the groove 2e, the nutrient solution is blocked by the dense roots in the groove 2e where the roots have grown and become dense, and the nutrient solution is prevented from flowing downstream of the groove 2e. In the hydroponic cultivation apparatus according to the present invention, as mentioned above, the weir 2f is formed in the groove 2e on the inner bottom surface of the horizontal gutter-like member 2. 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 from this groove it evenly flows into the valley groove 2e. ing.

上する。As described in detail, in the hydroponic cultivation apparatus according to the present invention,
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 cultivation board with a through hole is placed in the upper opening of the cultivation tank. In order to fit the multi-hole needle into the through hole of the cultivation tank board and make it protrude into the cultivation tank, a plurality of grooves extending from one end of the cultivation tank to the other end are formed on the inside bottom of the cultivation tank. Because of this, the grown roots grow in a three-dimensional manner with appropriate gaps, and the nutrient solution around the roots can be efficiently replaced by simply circulating the nutrient solution through the root wall, making it easier to harvest. Increased efficiency.
