Assessing of the thermic and hydric risk in Dealul Bujorului vineyard under likely climate change

Abstract

Characterization of a wine year consist of to analyze Agro-meteorological of the growing season of the vine (April to September) and the dormant period (October- March). It has placed particular emphasis on the evolution of hydro-thermal regime from air and soil, analysis is performed during the vegetation and repose period and limiting the action of these factors have an important role on the production of grapes obtained. The paper presents the agro-meteorological conditions in 2014-2015 periods, with direct effects on vine culture. Were processed and analyzed data specialist on temperature, rainfall and soil water content accessible on various depths (0-20 cm, 20-40 cm, 40-60cm, 60-80cm, 80-100cm and 0-100 cm). In assessing the potential agro-climatic resources available were considered data recorded at the weather Tg Bujor station (AGROEXPERT system).The trend of rains characteristics is the presence of torrential rains increasing rainfall number greater than 0,1mm and less than 5,0mm and decreases the number of leverage able rains (> 5 mm). Knowledge of the agro-meteorological characteristic is required for establish trend of thermic and hydric risk on the culture of the vine. By monitoring and surveillance phenomena risk / temperature and water stress can apply the most effective measures to prevent and mitigate negative effects on the culture of the vine.
