Abstract: An irrigation system with automatic irrigation liquid spraying device is described, comprising: a container (4), particularly for plants or flowers, the container being equipped with a perforated bottom; a bottom support (5) on which the perforated bottom of the container (4) is placed; at least one floater (3) equipped with at least one magnet (2) and placed in the support (5); at least one electromechanical reed-type device (1) operatively connected to the support (5) and adapted to be actuated by the at least one magnet (2) through a contact action of the reed blades driven by a magnetic field of the magnet (2); a tank (6) containing irrigation liquid; at least one pump (7) immersed in the tank (6), operatively connected to the container (4) on a side and to the electromechanical reed-type device (1) on another side.

Abstract: A Rastaplan.TM. system and container for the cultivation of plants. The methodology comprises a perfecting of the technique of subirrigation and is based mainly on a Rastaplan.TM. container-irrigator having on its peripheral structure a septum porous-roller without a bottom, the septum roller functioning as a continuous sub-irrigator of the substrate of cultivation, and on its internal structure, a truncated cone chamber that acts as a dripping chamber which permits aeration and subirrigation in sips around its own internal circumference. The Rastaplan.TM. container also includes an irrigation canal which acts as an evaporator distributor to allow the water level to oscillate between a minimum, under the border of the bottom of the container and a maximum, which is variable and regulable by a central float, which opens a closing needle of a water feeding duct to fill the irrigation canal as it dips below the minimum water level.
