<P>PROBLEM TO BE SOLVED: To provide a hydroponics device of fruit vegetables capable of being miniatured, supplying sufficient air and promoting stretching of roots around a whole cultivation bed. <P>SOLUTION: This hydroponics device of fruit vegetables is such one that the cultivation bed 3 is formed through stretching a root bed board 2 having air permeability and liquid permeability, on the upper part at the height of approximately the middle of a hydroponics bed 1 arranged with a culture solution supply pipe on the upper part, and a passage 4 for air supply and drainage is formed on the lower part. The inside of the cultivation bed 3 is coated with a root protecting sheet 5 having air permeability and liquid permeability without letting roots invade and a root stretch promoting means 12 is formed on the cultivation bed face so as to supply sufficient air to the roots and prevent growth badness caused by remaining of a culture solution. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
