Melnik E. Agreoclimatic Assessment in Forming of Grapevine Productivity.

Object- thermal resources as a conditions of vine productivity forming; the aim - development of the methods of warm suppluing estimation of vine taking into account heterogeneity of laying surface; methods - agrobiological, agroclimatic analysis and generalization of information, microclimatic calculations, mathematical-statistical, method of trends; novelty - the mezoscale features of day and night thermal resources distribution are determined, the parameters of microclimatic changeability of thermal resources of day and night under the influence of heterogeneity of laying surface are specified, the quantitative characteristics of the parameters of thermal mode influence and the rates of development and indexes of the productivity of different vine cultivars are estimated, the tendency of thermal resources change in the period of vine vegetation for the last 60 years is revealed; results - recommendations for the evaluation of warm supplying of well-being vine, which use for the optimization of placing of different vine cultivars at the level of farms and plots and for the correction of realization of different agrotechnical tools for vine growing during the vegetation period are worked out, that allows to reduce the risk of non-standard production obtaining on 20%; industry - viticulture.
