Description

The invention relates to agriculture and can be used in greenhouses and intensive light culture.

The purpose of the invention is to increase the operational reliability of the device.

The drawing shows a device for growing plants, a general view.

The device comprises bases 1, drain sections 2 and 3 of a large volume and supply section 4 of a small volume.

Above sections 2 and 3 on flat supports 5, having a small slope away from the supply section 4, moisture-conducting elements b are placed, the ends of which are placed on one side into the supply section 4, and on the other - in the drain sections 2 and 3. On the surface of the moisture-conducting elements b there is a porous hydrophilic substrate 7 and a rooting substrate 8 with holders of 9 plants.

The pressure tank 10 is connected by pipeline 11 to the feed section 4 through the regulator 12 of the solution level. The suction inlet of the circulation pump 13 through nozzles 14 and 15 located at the bottom of sections 2 and 3, and the drain header 16 is connected to drain sections 2 and 3. To deliberately stop feeding the nutrient solution, a valve 17 is provided, and to drain the solution from the supply, It section 4 - 1tutser with valve 18.

The device works with every day.

The nutrient solution from the pressure head and pipe 10 but the pipeline 11 enters the plug section 4 and flows into the drain sections 2 and 3 along the moisture transfer elements b, forming on their surface a fluid layer of the solution, over-wetting the root medium 8 and vymyvayun1y product of root secretions. The predetermined level of the solution in sections 2 and 3 is set by a level 12 regulator, which replenishes the supply of the solution to the supply section 4. To maintain the circulation of the nutrient solution, the pump 13 is periodically turned on and the solution from sections 2 and 3 is through 14 and 15 and the collector 16 enters into the pressure tank 10, behind the eye of the lock circuit, 1.

Porous 11 °; 1, a spoon 7, filled out of a hydrophilic polyethylene film with micropores and having contact with a moisture supply element 6 and 6, unimpededly passes water and power elements into a corrosive medium and protects the moisture source. elements 6 from root penetration and contamination.

In emergency situations, the feed solution from the overflow sections 2 and 3 enters the water supply system of the trunk.1 Oe. gementa.m b in the root environment, a long time supplying the root systems with nutrition and water. In this way, a high degree of exp is ensured;
