<P>PROBLEM TO BE SOLVED: To provide a device for hydroponic culture with which culture solution is uniformly supplied and given to the root system of a plant body vegetated in a cultivation pot even if at any place on a liquid supply mat the cultivation pot is placed, and effective utilization of liquid fertilizer can be achieved. <P>SOLUTION: The device for hydroponic culture is provided with the following: a water-supply mat horizontally laid and scooping up culture liquid charged in a liquid fertilizer tank via capillary phenomenon; and a plurality of cultivation pots arranged at least in a single raw on the water-supply mat and supplying the liquid fertilizer to the root system of the plant body via the water-supply mat, wherein the liquid fertilizer tanks are placed at both edge sides of the raw of the cultivation pots, and a means for making the liquid fertilizer in the liquid fertilizer tanks at both end sides vary in water level respectively, and alternately changing the level of the water in the liquid fertilizer tanks at both end sides. The water-supply mat supplies the liquid fertilizer from one end side of the raw of the cultivation pots, wherein the liquid fertilizer is moved to the other end side of the raw and simultaneously supplied to the root system of the plant body vegetated in the cultivation pot, and the flow of the liquid fertilizer in a raw direction of the cultivation pots on the water-supply mat is alternately changed into the reverse direction. <P>COPYRIGHT: (C)2008,JPO&INPIT |
