Application of electrical technologies to increase the productivity of cucumber in protected ground structures

Abstract

The rationale for the need to improve greenhouse complexes using energy-saving technologies for growing vegetable products, including cucumber, is presented. The purpose of the work is to justify the use of modern electrical technologies in protected ground structures to increase the productivity of cucumber. Based on the objectives of the study, the following tasks were identified: analysis of the operating modes of electrical equipment to identify ways to increase its productivity and reduce energy costs in the production of cucumbers on protected lands, significantly increase the efficiency of pre-sowing treatment of cucumber seeds by developing a system for automatic stabilization of the ultraviolet radiation dose. Energy requirements are related to the strategic choice of producers in relation to the structure, greenhouse and climate equipment used, such as ventilation systems, cooling, heating, as well as cultivation and adaptation methods. The search for new and efficient electrical technologies is becoming an urgent research aimed at optimizing the entire technological cycle and all stages of obtaining a high and high-quality crop. Including: 3D light surveillance models affecting the angle of the roof of the greenhouse in the direction, as well as this approach allows the greenhouse to receive 25% more natural light in the winter months, saving up to 15% energy; two new sensors will be tested to measure the true photosynthesis of crops; existing LED lighting has achieved an energy efficiency increase of about 40% in both summer and winter.
