Description

The invention relates to devices for growing plants in artificial conditions, in particular in protective and open ground.

 A device for growing plants is known, which includes cultivating softness in which a layer of a prorgano-mineral root medium and a layer of fine-grained moisture-absorbing material, separated by a perforated partition, and a reservoir of nutrient solution-tl are placed.

However, the known device does not ensure the effective use of nutrient salts from the permanent nutrient solution, since the holes in the perforated septum are clogged with penetrating roots, root healing G1mi and sediment salts, which leads to disruption of water-mineral metabolism and aeration of plant systems.

The aim of the invention is to increase the efficiency of the use of nutrient salts from the permanent nutrient solution.

The goal is achieved by the fact that the perforated partition is made of a polymeric material with capillary conical holes.

which are made in the central part of the septum with vertices towards the organo-mineral root medium, and in the peripheral parts of the partition with vertices toward the fine-grained moisture-conducting material; a layer of coarse-moisture moisture-conducting material is placed under the fine-grained moisture-conducting material.

In addition, drainage pipes are located on the surface of the septum, which are connected to the reservoir of the nutrient solution through an additional tank for collecting the flushing water.

Claims (2)

In the cultivation tank 1, made in the form of a gutter or tray of plastic, metal or asbestos cement, there is a layer of organo-mineral root medium 2 with a thickness of 5-10 cm and a layer of fine-grained moisture-conducting material 3, which are separated by a perforated partition 4 made of moisture-conducting polymer material with capillary conic holes that are made in the central part of the partition with the vertices towards the organo-minergic root medium 2, and in the peripheral parts of the partition - the vertices s in the direction of fine vlagoprovod conductive material 3. Under finegrained vlagoprovod conductive material 3 is a layer of coarse material 5 is laid on along the semicircular convex BejpxHocTH yenta element 6. Drainage pipe 7 conductive softening ua polar surface of the baffle 4. cultivation vessel 1 is connected to a reservoir of nutrient solution 8 through pipe 9 with a three-way valve 10. The reserve ar of the nutrient solution 8 is connected through pump 11 with a storage tank 12, which is connected to the cultivation tank 1 through floats th valve 13 Drainage pipes 7.avannye with additional capacity 14 for collecting breakthrough water through the three-way edge 10. Additional capacity 14 is connected to the reservoir of nutrient solution 8 through the pump 15. The pipeline 9 is connected to the discharge port of variable height 16. The device works as follows in a way. Plants are planted in a layer of organo-mineral rooting medium 2 placed in the cultivation tank 1 on the surface of the perforated partition 4. The nutrient solution from the tank 8 is pumped by the pump 11 to the accumulation tank 12, from which the float valve 13 is fed into the cultivation tank 1. The prescribed level of feeding the nutrient solution is maintained by a discharge pipe of variable height 16. The semicircular convex element 6 is designed to freely move the nutrient plant on the cultivation tank 1 and through the layer of coarse-grained and fine-grained moisture-conducting material 3 and 5 to the peripheral partition 4. In the central part of the performer Rowan partitions 4 races thief nutrient is supplied to the root systems of the plants through the tapered capillary apertures formed in the side of the organo-mineral ° rooting medium 2, which is used for materials with vysokoyvlagoemkostyu and moisture permeability. The root system of plants is located in the lower, wetted part of the root environment, which must be periodically cleared to prevent salinization. Wash water flows from the layer of organo-mineral root-based soil 2 to the layer of fine-grained moisture-conducting material through capillary conical holes in the peripheral parts of the partition 4, which are made to the vertices of the fine-grained moisture-conducting material 3. The excess of washing water is removed through the drainage pipes 7 with the appropriate position of the three-way valve 10 into the additional tank 14. From the additional tank 14, water is pumped by pump 15 to the reservoir of nutrient solution 8 for replenishment Its consumption for evaporation and transpiration of plants. Claim 1. A device for growing plants, including a cultivation tank, in which a layer of organic-mineral root medium and a layer of fine-grained moisture-conducting material are placed, separated by perforating. a partitioned wall and a nutrient solution reservoir, characterized in that, in order to increase the efficiency of nutrient salt utilization, the perforated partition is made of a polymeric material with capillary conical openings, which are made in the central part of the partition towards the organic-mineral root medium, in the peripheral parts of the partition - vertices towards the fine-grained moisture-conducting material, while under the fine-grained moisture-conducting material is placed with Loy coarse-grained material. 2. The device according to claim 1, so that with the purpose of permanent use of the nutrient solution, drainage pipes are placed on the surface of the partition that are connected to the nutrient solution reservoir through an additional container for collecting water.
