“…Gardening in our country for the production of fruits and berries does not yet saturate the market with a sufficient number of products (Alekseev et al, 2020;Dubenok et al, 2021). This is explained, first of all, by insufficient area, as well as low productivity of garden plantings.…”

Background: For the first time in the conditions of the Volgograd region, new knowledge was obtained, which made it possible, taking into account the changes in the morphology of the root system occurring during the formation of seedlings, the orientation of physiological processes and the biological needs of plants for their optimization, to justify a differentiated water-saving drip irrigation regime in combination with fertilizing vegetating plants, providing high-quality annual sweet cherry seedlings with high economic and water-saving efficiency, environmental tolerance. Methods: The experimental part of the work was carried out in the laboratory of breeding, seed production and nursery breeding 2017-2021 years. The productivity of the variety-rootstock combination was calculated relative to biometric parameters: crown projection area (S), crown volume (V), stem cross-sectional area (S). Result: In the course of the work, methods of watering stone crops, in particular cherries and their effect on survival, growth and development of seedlings in the nursery were studied. The scheme of experiments provides for an assessment of the influence of the water regime of the soil on the formation of the height of the central stem, the root system and the yield of seedlings of class 1 according to the variants of the experiment. Their values were greater than in the control, respectively, by 21 and 17 cm, 24-32%. At the same time, the yield of first-class seedlings in the third variant exceeds the second variant by 6%. According to the results of the conducted studies, the option of maintaining soil moisture at least 80% of the lowest moisture capacity during the adaptation period of the graft with a rootstock in a layer of 0.2 meters, followed by an increase in the soaking depth to 0.4 meters, proved to be the best. In the phase of the transition of seedlings to the dormant period, the pre-watering soil moisture should be maintained at least 70%.

The introduction of mineral substances into the soil through fertigation ensures the localization of the nutrients necessary for the plant in the area of the root system. However, under certain conditions, this method leads to soil salinization. When the soil dries out, salts are predominantly concentrated at the boundary between dry and wet soil, forming a salt fringe. The article describes the results of experiments and a software tool designed to simulate the process of redistribution of salts during soil drying. The results of calculations for soils of central Russia are presented, taking into account the main hydrophysical characteristics of the soil and the function of hydraulic conductivity under various initial conditions in the form of moisture gradients depending on the depth of the soil, the intensity and duration of irrigation, and the concentration of nutrients. It is shown that by selecting the appropriate initial conditions and irrigation regimes, it is possible to significantly reduce the intensity of the formation of salt fringes.
