Problems solved by technology

Compared with other traditional light sources, based on the advantages of low energy consumption of LED, it has become the mainstream light source of plant growth experimental devices, but many plant growth experimental devices still have the problem that the spectrum and light quantity cannot meet the needs of plants, and there is a problem of insufficient light regulation flexibility.
Traditional plant growth experiment devices generally have only one cultivation room, which has disadvantages such as low equipment utilization rate and poor temperature stability, which affect the regulation accuracy of environmental factors, and affect the accuracy of experiments and equipment utilization. Energy-saving plant growth experiment devices are yet to be developed. roll out

Abstract

The invention discloses an intelligent plant growth experiment device which comprises a first growing room, a second growing room, a water-cooled type LED area light source, a control system, a cover plate, a public air adjusting room and a CO2 fertilizer applying device, a compressor, a fertilizer bucket, a water tank and the like. The experiment device is cooled by the compressor and heated by a PTC, recycles the heat generated by an LED light source and controls the joint temperature control module of the public air adjusting room. The temperatures of the two growing rooms are adjusted and controlled by controlling the temperature of an air supply room of the public air adjusting room and the flow and rotating speed of draught fans of the growing rooms, and the independent management of the temperatures of the growing rooms can be achieved. The invention further discloses a temperature adjusting and controlling method of the intelligent plant growth experiment device. The intelligent plant growth experiment device is reasonable in design and convenient to use, and the temperature adjustment and control of the device are effectively achieved.

Description

technical field [0001] The invention belongs to the field of intelligent agricultural equipment and energy-saving management, and in particular relates to an intelligent plant growth experiment device and a temperature control method thereof. Background technique [0002] Breeding new varieties is an important means for humans to improve existing varieties, adapt to environmental changes, and improve species resistance. Appropriate artificial experimental devices for plant growth experiments can speed up the growth process. Exploring an artificial environment suitable for plant growth requires a large number of scientific experiments, and it is necessary to have artificial facilities that can precisely control environmental factors such as light and temperature. Therefore, there is a large demand market and potential demand space for intelligent plant growth devices. With the development of aerospace technology, people on earth are exploring outer space more and more frequen...
