Description

The utility model relates to the field of agriculture, in particular, to equipment for growing plants in artificial conditions using hydroponics, and can be used when conducting experiments in light culture, namely, obtaining experimental data on the growth, development and productivity of plants depending on growing conditions .

It is known that most plants, as they develop and transition from one phase to another, change their geometric dimensions and habit (Polevoy V.V. Plant Physiology: a textbook for biological specialties of universities: / V.V. Polevoy. - Moscow: Higher School, 1989. - 464 pp.).

It is also known that when conducting photobiological experiments when growing plants under light culture conditions, it is necessary to take into account the requirements for the amount of irradiance, spectral composition, and duration of radiation for different phases of plant development. Thus, for the seedling phase, a radiation spectrum close to daytime and relatively low irradiance is required; for the flowering phase, a predominance in the radiation of blue rays and average irradiance is necessary; for the fruiting phase, a predominance in the radiation spectrum of red rays and high irradiance is necessary. The duration of radiation can be set the same for all three phases of plant development (Kozai T., Niu G., Takagaki M. Plant Factory: An indoor vertical farming system for efficient quality food production. Second edition // Academic press. 2020. 516 p. ).

The closest technical solution is a device for growing plants [RU No. 217964, A01G 9/24, publ. 04/26/2023], containing radiation sources, a container for a nutrient solution, an air duct, a fan, working chambers for growing, a frame, a rack for trays with substrate, plants in pots, a submersible pump, a supply pipeline, a drain pipeline, a watering hose, a drain pan nutrient solution, top-up pipeline, solenoid valve, fixed water top-up sensor, control panel.

The known technical solution does not allow for the possibility of conducting experiments simultaneously for three phases of growing plants: the seedling phase, the flowering phase, the fruiting phase, which worsens the conditions for conducting research work.

The technical result of the utility model is to improve the conditions for conducting research work and increase the efficiency of equipment.

The technical result is achieved by the fact that the frame is additionally equipped with side walls with mounting holes, with the possibility of installing fixing bolts in them; the fixing bolts attach the movable shelves to the side walls, forming working chambers for growing, moreover, radiation sources connected by wires are rigidly fixed on the movable shelves with a control panel, while on two of the three movable shelves and one fixed shelf there is a rack for trays with a substrate, to each of which flexible watering hoses are connected at one end, the other end of which is placed in a supply pipeline connected to a container for a nutrient solution in which a submersible pump is installed, receiving power via wires from the control panel.

In fig. A device for growing plants is presented.

The device for growing plants has a frame 1 with side walls 2 rigidly fixed to it, containing mounting holes 3, with the possibility of installing fixing bolts 4 in them, which secure movable shelves 5 to the side walls 2, forming working chambers for growing 6, in each of on which irradiation sources 7 (Fig.) are rigidly fixed on movable shelves 5, connected via wires 8 to a control panel 9. On two of the three movable shelves 5 and one fixed shelf 10 there is a rack for trays with a substrate 11, with plants placed on them in pots 12. To each rack for trays with substrate 11, flexible watering hoses 13 are connected at one end, the other end of which is placed in the supply pipeline 14, connected to a container for nutrient solution 15, in which a submersible pump 16 is installed, receiving power via wires 8 s control panel 9. The working chambers for growing 6 have a common air duct 17, rigidly attached to the frame 1, with a fan 18, receiving power via wires 8 from the control panel 9.

The plant growing device operates as follows.

Before starting work, plants in pots 12 are placed on racks for trays with substrate 11 in three working chambers for growing 6, depending on the phases of development. In the first working chamber for growing 6, located in the upper part, plants are installed in pots 12 at the seedling stage, in the second, located in the middle, at the flowering stage, in the third, located below the second, at the fruiting stage. When connected to the network from the control panel 9, power is supplied through wires 8 to the radiation sources 7, as well as the submersible pump 16 and fan 18. From the radiation sources 7 to the plants in pots 12, a flow of photosynthetically active radiation, a certain spectral composition and intensity, determined by the phase plant development. The duration of the radiation is regulated by a timer (installed in the control panel 9, not marked) and is the same for all three working chambers for growing 6. The submersible pump 16 begins to pump the nutrient solution from the container for the nutrient solution 15 through the supply pipeline 14 through flexible watering hoses 13 to each rack for trays with substrate 11, providing food to the plants in pots 12. The fan 18 is turned on and supplies air to the common air duct 17, which through the mounting holes 3 enters the working chambers for growing 6. This is how processes occur in the device for growing plants that ensure radiation and temperature-humidity regimes, as well as plant nutrition.

Plants, as they grow and develop, change their geometric dimensions and habit, which requires an increase in the size of the working chambers for growing 6 in height. At the same time, the plant also requires that the irradiance be constant above the top of the plants.

To do this, remove the fixing bolts 4 from the mounting holes 3 in order, starting from the movable shelf 5 of the first working chamber for growing 6 and move three mounting holes 3 up, securing it in a new position, then a similar procedure is done with the movable shelf 5 of the second working chamber for growing 6, however, the fixing bolts 4 are moved two mounting holes 3 up, and finally for the movable shelf 5 of the third working chamber for growing 6, the fixing bolts 4 are moved one fixing hole 3 up. As a result, as far as the plants in pots 12 grew upward, the movable shelves 5 with irradiation sources 7 rigidly fixed on them rose up. The procedure is repeated as necessary.

The presented technical solution has a number of advantages over the known design:

the conditions for conducting research work are improved due to the possibility of adjusting the size of the working chambers for cultivation depending on the phase of growing plants by adjusting the installation height of the movable shelves using fixing bolts and mounting holes;

The efficiency of equipment operation is increased by providing different irradiation conditions in three working chambers for growing and maintaining them through movable shelves with irradiation sources rigidly fixed on them, also using a timer and the use of irradiation sources of a certain spectral composition.

A device for growing plants can be easily implemented in agriculture, with controlled cultivation of plants in artificial controlled and regulated environmental conditions.
