Abstract

The invention relates to crop production and can be used for growing plants in various experiments. The plant irrigation device contains a vegetative vessel 1 on the bellows 2 with a control liquid 3. A tube 4 connects the bellows to a water seal 8. Above the vegetation vessel is a Mariotta vessel. Under the weight of the vegetation vessel with plants, the liquid from the bellows is squeezed out, filling the water gate. The Mariotta vessel is filled with water from the water pipe 21 through the valve 13 and the tee 11 connected to the irrigation tube 9 coiled in a vertical plane. After closing the valve 13, the water from the Mariotta vessel flows into the growth vessel. In this way, the pressure in the Mariotta vessel drops, and the air passage tube 6, leaving the water seal, is filled with liquid to a level that balances the pressure in the irrigation tube. When the weight of the growing vessel is reduced, the fluid level drops, the air passes through the water seal and the air passage to the Marriott vessel, and the outflow into the growing vessel repeats. 1 Il. sl C

Description

7 ///////////////

The invention relates to crop production and can be used for growing plants in various experiments.

The purpose of the invention is to improve the accuracy of irrigation control.

The drawing shows a diagram of the proposed device.

The device contains a vegetative vessel 1 mounted on a bellows 2 with a control liquid 3. A tube 4 connects the cavity of the bellows 2 with a manometric tube 5, forming together with the air outlet tube 6 of the vessel 7 Mariotta Y-shaped water seal 8. The vessel 7 Mariotte is located above the vegetative vessel 1 and has an irrigation tube 9 rolled up in a vertical plane into a ring, one end of which is located above the vegetative vessel 1, and the other is fitted on the branch pipe 10 of the tee 11 connecting it to the water supply 12 through a stop valve 13 and 7 condemn Mariotte.

The device works as follows.

A vegetation vessel 1 with a plant and soil of a given humidity is installed on the bellows 2. Under the action of the weight of the vessel 1, the liquid 3 in the bellows 2 is compressed, its level in the manometric tube 5 rises, filling the Y-shaped water gate 8 to a certain level determined by the weight of the vessel 1. The Mariotta vessel 7 is filled with water from the water line 12 through the valve 13 and the tee 11. The air from the vessel 7 Mariotta is forced out through the air passage tube 6 and the stopper 8. After refueling

valve 13 closes and starts the outflow of fluid from vessel 7 of Mariotte through pipe 9 into vegetative vessel 1. At the same time, vacuum is created in vessel 7 Mariotta and pipe b is filled with control liquid 3 to a level that balances the pressure formed by the water column in the irrigation pipe. When water consumption in the growing plant 1 decreases its weight, the pressure in the bellows 2 decreases, the level of liquid 3 in the gate 8 drops, opening air access to the nozzle 6. At the same time the outflow of liquid from the vessel 7 Mariotta begins, the weight of vessel 1 increases, the level of liquid 3 in gate 8, the flow of air into vessel 7 is blocked, and the outflow is stopped. By reducing the weight of the vessel, 1 cycle is repeated. Invention Formula A device for irrigating plants that contains a growing vessel, a Mariotta vessel located above it with an air passage tube, a water supply system with a stop valve, an irrigation tube rolled up in a vertical plane into a ring, while the Mariotta vessel is connected to the water supply system and irrigation tube by means of a tee, characterized in that in order to increase the accuracy of the irrigation control, it is equipped with a fluid-filled bellows and a water seal connected to the bellows cavity, the vegetative vessel being mounted on the ONET and vozduhopropusk- on the tube communicates with the atmosphere by a water seal.
