ABOUT

 00 CE 00

The invention relates to agriculture and can be used in protected ground conditions.

The purpose of the invention is to increase the yield and reduce energy consumption.

FIG. 1 shows a plant growing device, longitudinal section; in fig. 2 - the same cross section.

The device includes a heat-insulated air duct 1 connected to a flow inducer (not shown) through the main air duct 2. The rastil is made in the form of a tray 3, which is the upper wall of the air duct 1 and is made, for example, of the same material as the air duct 1 Tray 3 is provided with retro-reflective covers 4 with openings for plants, recessed relative to its upper edges. Holes 5 are made in the walls of tray 3 above the level of cover 4, and holes 6 are below its level. In holes 6, upper ends are fixed to tube 7 sloping down to the bottom of tray 3. The system for feeding and draining the feed solution in tray 3 includes fixed above it, the feed nozzle 8, connected through the valve 9 to the main pipeline 10 of the nutrient solution, and the drain connection tl connected to the collecting pipeline 12.

The device works as follows.

Seedlings grown in mineral wool cubes are placed on the bottom of the lot.

at

3 and cover with lids 4. Nutrient solution is fed into tray 3 from pipe 10 through pipe 8, while its supply is dispensed by valve 9. At the opposite end of tray 3, the solution is discharged through pipe 11 and pipe 12 to the total collection capacity (not shown) for correction and reuse. From the main duct 2, the air with the specified climatic parameters enters the duct 1. Through the holes 5, the air then reaches the above-ground part of the plants, and through the holes 6 and the tube 7 - to their root system, ensuring Tivnuyu aeration solution.
