Kychylyuk O. Silviculture features of raising forest cultures of Scotch Pine of Volyn Polyssia

Object - processes of growth stands of Scotch Pine in the Volyn Polyssia. Aim - analyses and improvement scientific approaches and forestry practice concerning to silvicultural peculiarity of forming high-productivity stands of Scotch Pine in the research region. Methods - the main methods are: forestry-estimate - for exploratory sampling and estimate of growth or forest cultures; comparative ecology - for define forest site type; agro-chemistry - for determine physical-chemistry characters of soil; mathematical statistic - for processing experimental information; comparative history - for define dynamics of something characters in the interval.Novelty - in first substantiated and experimental proof advantage planting of forest crops of Scotch Pine without preparation of soil in the bor sites on the felled areas which age before 1 year. Define the methods and date introduction soil-fertile shrubs species under canopy of pine stands of Volyn Polyssia, also optimal age of stands for this introduction. Infirst determine, that number of absorbing roots in the fresh bor sites of Volyn Polyssia falls not from humous horizon to C-horizon, but it is inverse in leached and illuvial horizons. Reported, that result of positive effect of control forest draining on the stands of Scotch pine on the water-logged forest site types preserve even after repeat swampiness. Results of research - for implementation in practice of forestry the follow is being proposed: planting forest crops without preparation of soil on the felled areas which age before 1 year in the dry, fresh and moist bor sites with non-developed grassy turf and unharmed litter by manual labor plant. Introduction soil-fertile shrubs species under canopy of pine stands is recommended for increasing of biology resistance of this stands. Optimal age of stands for this introduction is 40 years. A method of this introduction is fall-sown dropping seeds. Practical verification of the got results is carried out in the State Enterprises "Starovigivsiy lisgosp" and "Ratnivske LMG", also Volyn region administration of forestry "Volynlis".
