An analysis of the technological operations of growing vegetables in a greenhouse shows that it is possible to reduce labor costs and increase the efficiency of the use of cultivation facilities when performing work with a special set of technical means. For a fundamental improvement in the technology of vegetable production in a greenhouse, stationary systems and robotic equipment are needed. The low quality of air temperature and humidity control in greenhouses necessitates control not only of the diameter and concentration of aerosol microdroplets, but also of the pressure in the pressure pipelines of evaporative cooling and additional humidification systems, as well as the amount of solar radiation entering the greenhouse, the level of physiologically active radiation created by additional illumination lamps. However, the characteristic features of production led to a number of specific problems in the choice of methods and means of automation. The main feature is the inextricable link between automated objects and biological processes in crop production, which are characterized by continuous formation and cyclic production. Manufactured products must be periodically collected, immediately processed, and then processed for its sale, long-term storage. In recent years, drip plant nutrition systems have been widely used, which make it possible to supply water and nutrient solutions locally to the root zone, in strictly metered quantities, and to maintain soil moisture content in a narrow range of specified values. The use of drip irrigation when growing cucumbers and tomatoes in a greenhouse allows you to increase the yield by 10..30% compared to traditional sprinkling, reduce the irrigation rate and fertilizer consumption, as well as reduce labor costs for irrigation.
