<P>PROBLEM TO BE SOLVED: To provide a hydroponics float intended for raising promotion of plants in hydroponics through effectively using raising rays. <P>SOLUTION: This hydroponics float 1 to be floated on a cultivation nutritious liquid 11 in a condition of holding a planting body 5 is composed of a flat plate-like buoyancy base 2 which has required buoyancy, and a charcoal layer body 3 which is made by mixingly coagulating carbon dust and set on the surface of the buoyancy base 2. As a result of this, raising rays L2 which are radiated from the charcoal layer body 3 of the float 1 are accurately irradiated to the plant of the planting body 5 which is held by the float 1 so as to obtain high irradiation efficiency, and the raising rays L2 which are radiated from the charcoal layer body 3 are absorbed in the plant 7 so as to increase the cell activity of the inside of the plant 7, and by both the synergistic effects, growth of the plant 7 is promoted. <P>COPYRIGHT: (C)2009,JPO&INPIT |
