PHYTOWALL WITH POLYCHROMATIC STIMULATORS OF PLANT GROWTH Russian patent published in 2010 - IPC A01G31/02 A01G9/02 

FIELD: agriculture.

SUBSTANCE: phytowall comprises vertical panel made of rigid, strong, waterproof, non-toxic and rot-protected plastic, fixed to wall of room or building, system of nutrient solution or water supply. Device includes reservoir for water and nutrient solution accumulation arranged in lower part of phytowall, submersible pump electrically connected to control unit and supply unit, and by means of discharge pipe - to distributor tube. Distributor tube is located across the panel on its upper end. Distributor tube includes outlet holes, with pitch equal to distance between pockets for plants. Pockets for plants are detachably fixed to the panel in rows along horizontal line and in columns along vertical line. Device comprises facility to supply of nutrient solution to roots of plants and source of light. Facility for supply of nutrient solution is arranged in the form of pad from synthetic material with high hydrophilic properties. Pad is attached to the panel by means of brackets, and in upper part it covers distributor tube made of plastic. Calibrated jets that guide nutrient solution flow towards pad are installed in outlet holes of tube. Ratio of total flow rate of jets and reservoir capacity provides for time of drip irrigation with nutrient solution in autonomous mode of supply for at least two weeks at nominal room temperatures. Optionally, tank is made of wood with water-repellent treatment or plastic. Source of light has artificial polychromatic radiation and consists of horizontal lamp fixed to upper part and vertical lamps fixed to sides of phytowall panel, or is mounted on external brackets to room wall. Lamps are arranged with the possibility to provide for modes of spectrum change along with stages of phytowall plants life: formation of root system at the first stage and formation of leaf mass at the second stage, as well as mode of additional radiation to required duration of daylight hours. Lamps are placed into reflector, where one, two or more lamps may simultaneously be located, depending on current stage of phytowall plants life. Control unit is equipped with timer for submersible pump connection within 10-15 minutes from 3 to 8 times per day depending on moisture and temperature of air in the room, and timer of lamps operation mode switching control.

EFFECT: invention makes it possible to improve operational capabilities and intensity of plant growth.
