The device for cultivating plants includes a housing 1, made in the form of a cabinet with a door 2, which contains a touch control panel 3, inside which the controller is located, and tinted glass 4. At the same time, housing 1 has an air inlet 5, an outlet 6 of purified purified air and an outlet 7 warm air and is divided into three compartments: the upper technological compartment 8, the lower technological compartment 9 and the chamber 10 for growing plants.

Inside the plant growing chamber 10 there is an ultrasonic sensor 11, an HD camera 12, climate control sensors 13, side and ceiling lighting modules 14, inlet 15 and air outlet 16 in the side walls, as well as openings for planting in the bottom.

The upper technological compartment 8 contains the ventilation module 17, and the lower technological compartment 9 contains the module 18 for growing plants.

The ventilation module 17 contains an integrated means 19 for humidifying air flows, operating on the principle of evaporative cooling and containing inside a liquid pan, a pump, nozzles and a heat exchanger (not shown in the drawing), a carbon dioxide mixing means 20, a circulation circuit fan 21, an air exchange circuit fan 22 , an ionization element 23, a temperature lowering valve 24, a temperature raising valve 25 and a carbon filter 26. In addition, the ventilation module 17 contains a differentiation means integrated into it It is operated by air fans (not shown in the drawing), which is operated by fans 21 and 22, and uses air inlet 15 and air outlet 16 as deflectors.

Plant growing module 18 contains root support bowls 27 and 28, equipped with an aeroponic and hydroponic nutrient solution supply system, a valve system 29, nutrient solution condition monitoring elements 30 including sensors for salts, nitrates, acidity and temperature of the nutrient solution, nutrient solution tank 31 and tanks 32 with liquids. The means of introducing microorganisms consists of tanks 33 and 34, inside of which the bacteria mycorrhiza and trichoderma are located, while the tanks 33 and 34 are provided with flaps (not shown in the drawings).

The utility model works as follows.

The door 2 of the device for cultivating plants is opened, the nutrient solution is poured into the tank 31 and the containers 32 with liquids are installed. The colonies of microorganisms are placed in the tank 33. Plants (not shown in the drawings) are placed inside the plant growing chamber 10 and the roots are placed in the bowls 27 and 28. The door 2 is closed and, using the touch panel 3 controls, the data about the planted plants are entered into the controller. The controller selects the necessary program for the care of plants at all stages of their growth.

The plant growing module 18 receives a command from the controller to prepare a nutrient solution by mixing into the tank 31 fluids from the tanks 32 via the valve system 29. The nutrient solution condition monitoring elements 30 register changes in the content of minerals, salts, as well as the acidity and temperature of the nutrient solution and transmit them to the controller, which, when the required values are reached, stops the mixing of liquids in the tank 31. The medium of the aeroponic and hydroponic nutrient solution sprays the nutrient solution on plant roots. At the same time, the controller registers the physical state of the plants by means of the HD camera 12 and makes corrections to the composition and the intensity of the spraying of the nutrient solution on the roots of the plants relative to the physical state of the plants. At the same time, mycorrhiza from the tank 33 enters the tank 31 and, together with the nutrient solution, moves to the plant roots, increasing the amount of nutrients absorbed by the plants. The controller registers a sufficient level of mycorrhiza in the tank due to nutrient solution control elements 30 and overlaps capacity 33. To reduce the risk of pathogens in plants, the controller opens capacity 34 and trichoderma enters tank 31 and moves with the nutrient solution to plant roots, protecting the plants. When registering a sufficient volume of trichoderma, the controller covers the capacity of 34.

The ventilation module 17 receives a command from the controller to activate the circulation circuit fan 21 and air begins to flow into the housing 1 through the inlet 5 and into the growing chamber 10 through the inlet 15, and due to the valves 24 and 25, the temperature inside the chamber rises and falls. When this controller registers the change in temperature and humidity inside the chamber 10 by means of sensors 13 climate control. In the case of a decrease in humidity, the controller gives the command to activate the pump of the air flow humidifier 19, which by means of nozzles sprays liquid onto the surface of the heat exchanger, from which surface it enters the circulation loop, lowering the temperature and increasing the humidity inside the growth chamber 10 to create favorable conditions for growth and development cultivated plant species. In case of exceeding the temperature and / or humidity values, the controller gives the command to activate the air exchange circuit fan 22, resulting in air passing through the air outlet 16 from the growth chamber 10 through the ionization element 23, the carbon filter 26 and, free from pollen and unpleasant odors, gets out through the outlet 7 in the housing 1. As a result of ventilation of the growing chamber 10, the controller by means of sensors 13 of the climate control registers a drop in the level of carbon dioxide necessary for the effective passage of the photosynthesis in the cells of the plant, and gives the command to activate the carbon dioxide mixing facility 20 inside the chamber 10 and the required level of carbon dioxide is restored.

The controller registers the height of the plants by means of an ultrasonic sensor, as a result of which it receives data on the sufficient development of the stem of the plants. The controller gives the command to the fans 21 and 22, and they begin to rotate intermittently at different frequencies, imitating the wind flow, as a result of which the plants begin to sway and their stem is strengthened, and the efficiency of nutrient absorption by the plants increases.

The controller receives data from the ultrasonic sensor 11 of the HD camera 12 and the climate control sensor 13, which includes a light sensor, about the current physical condition of the plants and commands the side and ceiling lighting modules 14 to activate the LEDs of the light spectrum required at this stage of plant growth, forming the necessary the luminous flux and composition of light to accelerate the growth of vegetative mass by the plant, as well as increasing the height and thickness of the stem. At the same time to eliminate the possibility of heating the air inside the chamber 10 of growing plants and changing climatic conditions, warm air from the ceiling lighting modules 14 is discharged through the outlet 7 of warm air. The controller registers the insufficient illumination of the plant 35 and changes the position of the lighting module, after which the required level of illumination of the plant 35 is restored.

The controller registers changes in the physical state of the plants by means of the ultrasonic sensor 11 and the HD camera 12, and constantly makes adjustments to the operation of the side and ceiling lighting modules 14, the ventilation module 17 and the plant growing module 18. In this case, the controller registers the lag or advance of the growth and / or development of individual plant parts and compares the growth and development dynamics of the plants themselves. In case of deviation of these parameters from the given controller, depending on the readings of the ultrasonic sensor 11, HD camera 12, climate control sensors 13, as well as nutrient solution condition monitoring elements 30, makes corrections to the operation of the humidification means 19, means of differentiating air flows and means of introducing microorganisms. When forming and ripening fruits in plants, the controller sends a signal to the touch panel 3 about the need to harvest.

Thus, a technical result is achieved, which consists in ensuring balanced growth and development of plants, thereby increasing the efficiency of their cultivation.
