Kaidyk O. Bioecological and technological features of an artificial reconstruction of wood plantings of scots pine in conditions of Kyiv Polesye

Object - processes of growth and development artificial plantings of scots pine in southern part of Kiev Polesye. Purpose is perfection theoretical approaches and practical actions of creation and cultivation forest cultures of scots pine on various categories grounds of Kiev Polesye. Methods of research: silvicultural-taxation - for pawn trial areas and definition biometric parameters phytocenoses; geobotanical - for description and characteristic alive ground cover; agrochemical - for establishment chemical and water-physical properties of soil; be measuring-weight - for establishment biometric parameters of skilled plants; mathematical statistics - for processing experimental data. Novelty - for the first time was lead an economic estimation of six variants technology preparation cutting down for creation of oak-pine forest cultures in modern economic conditions; scientific representations about influence of a way of prelanding cultivation of ground on cutting down areas and local entering mineral fertilizers at creation of scots pine cultures on them survival and growth in first three years in conditions poor fresh subor are profound; the knowledge of expediency of use landing material which has been brought up from seeds local plus trees at reafforestation and forestation scots pine is profound; it is generalized scientific experience and it is proved expediency reduction of quantity leaving behind ground, and also cultivation of sealants and agricultural crops in wide row width pine cultures (to 3-years age) in conditions fresh subor in region of researches; for the first time presence of close direct correlation communication between the maintenance of basic elements of a feed in the top layer of ground both survival and morphometry characteristics two-year-old seedlings of scots pine is revealed; the knowledge concerning optimum variant of prelanding cultivation of ground on mellow soil the grounds and its influences on growth and development 5-years seedlings of scots pine is profound. Results ofresearches - high efficiency of variant of downturn stubs at a stage of carrying out cutting trees is shown; the expediency of cultivation ground on cutting areas by strips with local entering mineral fertilizers simultaneously with creation of cultures is established; it is established, that volumetric and weight parameters 5-years seedlings of scots pine closely correlate with a diameter seedling at root neck; by means of the received dependences between morphometry parameters seedlings of scots pine, operating with a parameter of diameter at root neck, it is possible to establish with high probability weight and volume seedlings and their separate bodies; it is proved, that on cutting areas in poor versions fresh subor where is absent grassing, satisfactory results survival and growth seedlings a pine can be received at landing seedlings in the raw ground.
