The article analyzes the indicators characterizing modern structure in terms of diameter in provenance trial plantations of Scots pine, created in 1959 by manually planting 2-year-old seedlings using Kolesov's sword at the Stupinskoye Pole training ground in the Voronezh Region, with an area of 26.1 hectares on agricultural land. Based on the data of continuous tree counts on 32 temporary sample plots established in 2018-2020, and representing 18 forest-steppe and 14 steppe ecotypes from the forestries of the European part of the Russian Federation and Ukraine, the diameters of the thinnest, middle and thickest pine trees were determined, as well as rows of their distribution were built for 2 and 4 cm steps of thickness. It was found that distribution of trees in the forest-steppe ecotypes of pine has a unimodal character, typical for a normal distribution, but with insignificant right-hand asymmetry. The distribution of trees of steppe ecotypes is also asymmetric, but bimodal one. In this case, the top of the first right-sided and smaller peak falls on a step of 20 cm thickness, and the top of the second, higher peak falls on the central step of thickness (28 cm), which is associated with the natural cyclic-wave decay of small-sized pine trees of steppe ecotypes growing in conditions of the forest-steppe, where the object of research is located. In pine plantations of forest-steppe ecotypes, 65.3% of the trees are concentrated in the five central steps of thickness, and in the steppe ecotype - only 52.0% of their total number

Forest Conditions

Creating forest plantations, used in these soil preparation techniques, agricultural activities, as well as the selection of the optimum species composition and subsequent silvicultural treatments are developed in accordance with different types of forest conditions. These conditions greatly affect the overall performance and progress of growth stands. The results of numerical analysis and the use of tables of plantation growth of Scots pine growing in various types of forest conditions (A2, B2) are given, reflecting changes in the stock of stem wood with age under the influence of thinning. According to the cutting age (maturity) for Scots pine optimal thinning regimes are presented in protected forests of forest-steppe region of the European part of the Russian Federation. To determine the optimal regimes of thinning of forests computer program was used that allows you to optimize conducting of thinning and calculate the objective function of stem wood for different target diameters of technical maturity. Computer calculations made it possible to compare the effectiveness of silvicultural thinning in Scots pine plantations according to standard regulations and recommended modes of forest care. Proposed options of thinning are different in conducting more intensive thinning at the age of clearings at forming the composition of plants and relatively low percentage of thinning at the age of caring for growth stands. The comparative characteristic of the performance of Scots pine plantations and the target output function of stem wood depending on the desired diameter is given. As a result of numerical calculations some conclusions and recommendations for thinning in pine plantations were obtained, depending on the type of site conditions.
