Abstract (English):
Forest reclamation complexes in the Rossoshan district of the Voronezh region are mainly represented with the participation of white acacia, silver birch, green ash, common elm and Tatar maple. The area occupied by them in the agricultural landscape is 2009 hectares. In cultures of hanging birch at the age of 19 years with a change in width from 6.0 m to 15.0 m, there is a decrease in the preservation of species by 8.8% and a decrease in wind protection height by 16.5% with a plant density of 3334 pcs / ha and placement of 3 , 0 x 1.0 m. According to the growth of plantings, they are estimated as Ia class of bonitet. In mixed crops aged 34 years, consisting of fast-growing and accompanying species with a planting width of 16.0 m, the highest height is for drooping birch (20.1 m), the lowest for green ash (14.3 m). The safety of such breeds is 46.8% and 60.6%, respectively. Forest belts, represented by white acacia, drooping birch, Tatar maple at the age of 36 years, have a preservation of species of 38.3-55.2%. The drooping birch has the highest height (22.4 m). In artificial linear plantations, consisting of common elm, drooping birch, Tatar maple and green ash at the age of 38 years, the greatest preservation is observed in the Tatar maple (54.7%), the lowest in green ash (32.7%). The drooping birch has the greatest windproof height (20.6 m) and is estimated in growth according to the Ia class of bonitet. Each breed has certain ecological and biological properties.
