FREMGANGSMAADE TIL INTENSIV DYRKNING AF VANDPLANTER OG INDRETNING TIL UDOEVELSE AF FREMGANGSMAADEN

摘要

The device comprises a tank (1) in which is arranged a nutritive aqueous solution (2) on which float aquatic plants (3) exposed to solar radiation passing through a cover (4). According to the invention, a solar-energy detector (5) is provided which is connected to a motor (12) for moving along the plants (3) via a drive cable (7) and floating elements (6) at a speed which increases with the solar energy received by the plants.
