Abstract
The most important factor affecting the yield of agricultural crops is the formation of an optimal water regime in the active soil layer. One of the main methods of carrying out such works is sprinkling, since it is closest to the process of natural precipitation. At the same time, existing water sprinklers do not provide watering agricultural lands that meets agro-technological requirements due to the design features and the specifics of the landscape on which they are used, forming in the process of watering zones with excessive and insufficient moisture. In this regard, a positional water sprinkler has been developed, which has the ability to water along a path close to rectangular. Obtaining this trajectory is achieved due to the design features obtained as a result of mathematical modeling. The article presents the structural diagram of the developed water sprinkler, considers the principle of its operation, presents the results of mathematical analysis and modeling of kinematic processes occurring during its operation. The above research results show that the use of the proposed water sprinkler will improve the quality of watering due to the watering trajectory closest to rectangular.
Highlights
Changing the water content in the growing environment of plants allows to control the production processes taking place in them
It should be noted that the existing irrigation systems consume 15-20 % of water resources more of the required volume, which leads to some deterioration of hydrogeological
To obtain consistently high yields of agricultural crops, the determining factor is the availability of the required amount of moisture and nutrients in the root layer of the soil
Summary
Changing the water content in the growing environment of plants allows to control the production processes taking place in them. Regular watering helps to maintain the required moisture content in the active soil layer, which is especially important for the growth and development of crops [2,3]. Given the above, it is worth considering and scientifically substantiating the water regime of the root layer when growing agricultural plants. The most important task of land reclamation science is the development and implementation of water-saving technologies into the practice of irrigated agriculture aimed at increasing the productive use of irrigation water [5]
