INVESTIGATION OF THE OPERATION OF ELECTRICAL EQUIPMENT FOR FEEDING PLANTS WITH CARBON DIOXIDE IN PROTECTED SOIL

Abstract

Carbon dioxide, along with nutrients, light and water, serves as one of the most important factors for growing plants. But the carbon dioxide contained in the atmosphere may not be enough. In modern crop production, they are increasingly inclined to use additional equipment, with the help of which the CO2 fertilization of plants is carried out. At the same time, control over the processes of vegetation and flowering (fruiting) improves. (Research purpose) The research purpose is creating an experimental setup and conduct experiments. Determine the external parameters that affect the maintenance of the required CO2 level. Find ways to control the concentration of carbon dioxide, independent of external conditions. (Materials and methods) Analyzed domestic and foreign literature, based on their own works on this topic, conducted experiments. An experimental installation for spraying carbon dioxide in a volume simulating the construction of protected soil was installed. (Results and discussion) We performed 4 measurements with a time difference of 2 hours. It was shown that the experimental setup based on the compiled algorithm levels the influence of external factors and keeps the set value of CO2 (600 ppm). Readings were taken from sensors located in the area of carbon dioxide cloud spraying, adjustments were made by affecting the operation of electric nozzles. (Conclusions) It was found that it is possible to solve the problem of lack of carbon dioxide when growing plants in the construction of protected soil. For this purpose, it was proposed to use carbon dioxide supply units directly to plants, capable of taking into account and correcting the movement of gas in the construction of protected soil. The results of the experiments carried out on the operation of electrical equipment for feeding plants of protected soil with CO2 were presented.
