The article describes the need for and the results of research of the process of carbon dioxide absorption by the largest artificial forest in Europe growing in the South of Ukraine, near the town of Oleshky (Tsuryupynsk), on the Lower Dnieper sands, due to increase of air temperature of the planet. Forecasts of scientists around the world force us to concentrate all possible efforts of the planet to preserve its atmospheric air temperature at the level not exceeding by 1.5 – 2 °C. This forestry aroused scientists’ interest because of its location in the Steppe zone of Ukraine and its origin. The article analyzes the current state of the forest hunting range. The species of trees prevailing in the forest stand and occupying the largest area in terms of age classes are specified. Areas of wood species under study depending on their age are also shown. Study of selected species, namely Crimean pine and Scotch pine, in terms of intensity of carbon dioxide absorption by needles from autumn 2015 to summer 2016 was also carried out. Seasonal performance in the form of graphs with analysis of the process under study was demonstrated. The lowest and the highest values of the process under study were noted down. Obtained results make it possible to analyze the processes of carbon dioxide absorption throughout the year by pinaceous species, namely by Crimean pine and Scotch pine.
It is shown the dynamics of growth of millet leaves surface after the interphase periods of plants developments. Clean productivity of photosynthesis of plants of millet was determined after the interphase periods of development. By experimental researches definite dependence the productivity of photosynthesis of plants millet on the sizes of leaves surface.
In work numeral computation of offensive of phase is analysed «shoots» of spring barley in the Kiev region depending on the complex of agrometeorological factors. Computation of period sowing-shoots is based on decomposition of equalization of logistic curve in the row of Taylor’s series. Estimation of all necessary parameters of the offered model is produced. The analysis of comparison of actual and computation dates of phase is conducted «shoots».
The theory of the biological temporal field, able to unite or «work» at a different level of hierarchy of organization of processes of photosynthesis, photorespiration and respiration of maintenance, is offered. Coming from a theory, by natural appearance the subdivision of productional process of plants on photosynthesis, photorespiration and respiration of maintenance is carried out. Becomes a photorespiration role is clear – it is a process providing indissoluble communication of motions of the biological temporal field. The factor of the biological temporal field is an uniting link at a different level of hierarchy of biological processes of plant.
Estimation of the generalized characteristic of soil-climatic terms millet of tillingl and its productivity is given.
The article describes Tsyurupinsk Forest Hunting Range as the most powerful natural ecosystem having an effect on regulation of technology-related processes, namely on reduction of carbon dioxide stress on the environment. Needles of Scots pine and Crimean pine serve as the object of research. Needles were selected from pine trees occupying the largest areas of growth with regard to age class. The studies were conducted using the gasometrical method. The chosen method is based on measuring the rate of absorption of carbon dioxide by needles. Measurement of areas of examined portions of pine trees took place as well. The role of forests for dry steppe subzone of Ukraine was also determined. Data of photosynthesis process occurring in needles of coniferous woods prevailing with respect to areas of growth are demonstrated. The analysis for study of dynamics of carbon dioxide absorption in September – November of 2015 is presented. The most favourable periods of the process of absorption of CO2 are described with a certain decline noted. It has been proved that intensity of absorption of carbon dioxide by needles of Crimean pine is almost twice more than absorption of carbon dioxide by needles of Scots pine.
The influence of agrometeorological conditions on photosynthetic productivity of soya is under consideration in the paper. Net productivity of the photosynthesis of soya plants was determined by interphase periods of development.
They are estimated the change of agro climatic resources in the Ukrainian part of the Danube Delta sub-basin in 2011-2030 years and 2030 – 2050 years due to climate change, in a compared with the base period 1986 – 2005 years. For the assessment of climate change in Ukraine A1B scenario, the regional climate model MPI-M-REMO, a global model – CHAM5-r3 have been used. The evaluation of the heat and humidity of the growing season, and evaluation of the changes of agro-climatic conditions of winter wheat in relation to climate change has been done.
The estimation of change climatic recourse of the Lugansk region was examined in 2011-2030 and 2031-2050 years in connection with the changes of climate in compression by base period 1970-2010 years. Using models was assessed photosynthesis production and vibrations of the productivity of winter wheat in the conditions of change of climate.
The submodel of process of frost resistance and wintering of the winter wheat as a component of complex dynamic model of growth, development and formation of the crop production.
The problem of description, evaluation and prognostication of duration for sowing-shoots period of agricultural cultures is examined. The solution to the problem is founded on an approach being a problem of biological time of plants. Iterative computation equation for consideration of a complex of agrometeorological factors affecting the duration of sowing-shoots period is derived on the basis of expansion in Taylor’s series. Thus, the basic processes of ontogenesis, photosynthesis and plant respiration, are taken account of.
The results of a numeral experiments with the estimation of late frosts influences, observed during 3 ten-day periods of 11 being under study, on the accumulation of potato plant individual organ biomass and productivity formation as a whole conformably to Kirovograd region conditions are stated.
