Research of the operating modes of a combined drip irrigation system with aerosol irrigation for cultivating a cherry orchard

Abstract

Relevance. Irrigation of agricultural crops plays a key role not only in increasing the yield of these crops, but also in preserving it, especially under stressful temperature conditions. One of the effective methods of water conservation during irrigation is drip irrigation. Drip irrigation technology allows you to accurately dose water, taking into account the needs of specific crops and maintaining an optimal level of soil moisture. It is important to note that this technology helps save water and reduce the risk of soil overmoistening. In addition to drip irrigation, there is also aerosol irrigation. This irrigation technology allows more efficient use of water resources and provides optimal conditions for the ground air layer for the growth and development of plants under stressful temperature conditions.Methods. The objectives of the study are to study the technologies and technical means of irrigation of a young cherry orchard to maintain optimal modes through the use of drip irrigation with aerosol irrigation in the Central part of the Non-Chernozem zone of Russia. During the research, two factors were analyzed: studying the impact of various irrigation methods and moistening volumes on the formation of trees of the Gostinets and Zhukovskaya varieties of sweet cherry.Results. The field experiment is conducted on the territory of «Kolomenskaya Yagoda» LLC in the Moscow Region. The conducted studies have shown that the selected irrigation method using a combined irrigation system on sod-podzolic soils in the central part of the Non-Chernozem zone of Russia for growing a young cherry orchard of the Gostinets and Zhukovskaya cherry varieties meets the criteria of environmental safety and economic efficiency.Conclusion. From the point of view of profitability, it is most effective to grow a young cherry orchard by maintaining humidity in the root zone of the soil within 80-100% of the lowest moisture capacity and relative humidity of the ground air layer in the range of 55-70%.
