Shaposhnikova O. Ampeloecological Basis of Determination of Microzones for Vine Growing in the Lower Dnieper Left Bank Area

Aim of research: theoretic basis of microzones determination and elaboration of scientific and methodic approaches that with taking into consideration of ecological particularities will provide optimization of vine plantation placing for stable high quality yield production in the Lower Dnieper Left Bank Area. In the thesis the work on determination of optimal microzones for vine plantation placing on the Lower Dnieper sandy area is made on the base of complex analysis of ampeloecological conditions of the territory. Quantity and quality register of vineyards (cadastre) is conducted with taking into account of ampeloecological investigation data. It is determined, that the most favorable for planting and developing vines on the sandy soils of the left bank of the Lower Dnieper are plots with loam layers and buried soils (chernozems) or which are underlain by materials of weathering of limestone and marl on the root reachable depth. Four microclimate districts are defined. It is determined, that leadingfactors which determine redistribution of mean of absolute minimum of the winter air temperature on the territory of the Lower Dnieper left bank are the mutability of soil cover and influence of the Dnieper. Agroclimatic evaluation of vine productivity is made with taking into account of possible changeability of calculation yield level in dependence on heterogeneity of surface or diversity of landscapes, on the territory of the Lower Dnieper sandy area. It is proposed a new scheme for conducting of vine plantation cadastre with application of data of ampeloecological investigation.
