It is considered the agro-climatic conditions changing of grape growing in the Northern Black Sea. The estimation of wine grapes vegetative phase’s dates offset in the implementation of climate scenarios was done. Based on a model developed by the authors the yield estimated due to potential climate change.
The longperiods dynamic pattern of growth of general dry biomass of agricultural cultures is offered, in a basis which the equalization of logistic curve, based on supposition about the swaying processes of biological time of plants in ontogenesis, lies to. The period of vibrations of biological time and amplitude of vibrations are wholly and fully determined by tension of factors of external environment. Research of model is conducted and positive estimation of its adequacy is got to the real object of researches. It is accounted for the fact of parabolic dependence of growth of biomass from the state of tension of factors of external environment. Differential equalization of vibrations of biological time in ontogenesis of plants is given.
The results of numerical experiment on appraisal of crop capacity level changing of winter wheat under the influence of lead pollution and different quality of irrigating water are given.
Conformities to the law of influencing of agroklimaticheskih terms on the dynamics of forming of increases of different levels of productivity of millet are set.
The results of numeral experiments of modeling of process of forming of agroecological level of potential productivity of winter wheat in the Odessa region are presented.
Estimation of the sun radiation e influence on the increasing of phitomass regrettable cultures is given. It is set, that influence of sun radiation essentially relied on the terms of the water supply sowing, density, terms and norms of irrigation and terms and norms of bringing of the fertilizers.
