The invention relates to agriculture, namely hydroponic equipment, and is in addition to the main auth. № 1397006.

The purpose of the invention is to improve root nutrition by expanding the range of nutrient solution supply intensity.

FIG. 1 shows a diagram of the device; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a scheme for providing plants with a nutrient solution.

The device includes a pressure tank 1 for solution, connected by a pipe 2 to tank 3 to supply a nutrient solution. A pressure pipe 4 with a needle valve 5 connects to a pressure tank 1 a horizontal pipe 6 with openings 7. A reservoir 8 for collecting nutrient solution is connected by a pipe 9 to an intake pipe of a pump 10, the pressure pipe of which is connected by means of a pipe 11 to a tank 1.

The upper part of the moisture-conducting wick 12, the substrate 13 and the film porous root-substratum 14 is in the reservoir 3 with the nutrient solution, the wick 12 and the tube 6 with the holes 7 being fixed in the gap gap between the substrate 14 and the substrate 13, between which the wick 12 is below a flat capillary 15 is formed. A tube 6 with openings 7 is placed in a waterproofing cover 16 with a longitudinal slit made of polyethylene film or other waterproofing material. The tube 6 in the cover 16 is placed with the possibility of axial rotation. On top, the device has removable covers 17 and 18, between which there is a gap for the stems of plants whose roots are located on the substrate 14. The covers 17 and 18 are closed on top with a reflective material 19. The opaque door 20 and the transparent door 21 provide observation of the growth and development of the roots.

Continuously leak a layer of solution, wetting the substrate. The flow rate is adjusted by turning the tube in a waterproof cover. In this case, the holes in the tube partially overlap or, on the contrary, open. 3 il.

Seal 22 is made of microbiologically resistant material. The plant seedlings in the device are fixed by removable holders 23, which are suspended on a circular plank 24. In the device there are also main holders (not shown) that hold adult plants.

In the pressure tank 1 there is a float 25 in contact with the limit switch 26. In the tank 3 at the end of the pipeline 2 a valve 27 is installed associated with the float 28. The vertical stand 29 serves as a guide for changing the height of the valve 27. The tank 8 has a nutrient solution collection 30 and a float 31 in contact with the upper limit switch 32 and the lower limit switch 33.

Plant sprouts or seeds are fixed on the upper part of the film substrate 14, which is evenly wetted with a solution flowing through the wick 12 from the tank 3 and flowing from the holes 7 of the tube 6 to the flat capillary 15. From the flat capillary 15 the solution flows into the collection 30, from which enters the tank 8. When the solution reaches the set upper level, the limit switch 32 turns on the pump 10, the pumping solution to the tank 1. The pump 10 is turned off by a command from the limit switch 33 or the limit switch 26. The level of the solution in the tank 3 is kept constant by means of a valve 27 with a float 28.

Along the flat capillary 15, a layer of solution will continuously flow, ensuring uniform wettability of the entire surface of the substrate 14 and the supply of fresh nutrient solution to the plant roots. The intensity of the supply of the solution into the flat capillary p 15 is controlled by moving the valve 27 along the rack 29 and, accordingly, by changing the level of the solution in the tank 3, as well as by turning the tube 6 with the holes 7 around its axis, thereby adjusting the overlapping of the holes with the waterproofing cover which the solution flows out. The needle valve 5 provides a constant pressure of the solution in the tube 6. The change in the capacity of the capillary 15 occurs by changing the distance between the substrate 13 and the substrate 14 due to their elasticity.

Since the intensity of feeding the nutrient solution to the plant roots in the device does not depend on the porosity of the substrate 14, this allows the use of thin and durable materials, such as mylar and nylon tissue, as the substrate 14.
