Abstract

Thermoregulation in plant systems is one of the main functions of transpiration, which plays the role of the upper terminal mover of the water current. It creates a continuous flow of water from the root system to the leaves and other vegetative organs of the plant, linking them into a single whole. This flow transports dissolved mineral and partially organic nutrients. The study of thermoregulation on plants of the strawberry garden variety Asia was conducted in 2019–2020 in the department of Closed Artificial Agroecosystems for Plant Growing at the Federal Scientific Agroengineering Center VIM, Moscow. The object of the study was thermoregulation processes occurring in plant systems. The subject of the study was the culture of garden strawberry Fragaria×ananassa (Weston.) Duchesne of the ‘Asia’ variety. As a source of light energy (LE) we used a thirty-six-watt bispectral lamp, consisting of 12 three-watt LEDs of red (660 nm) and blue (450 nm) colors at a ratio of 10:2, providing constant illumination of the culture. The study results allowed for a digital control of the efficiency of production processes in plant systems, due to the implementation of a step-by-step control algorithm in digital devices. The algorithm makes it possible to establish the maximum temperature difference between the leaf surface and the air.
