Research on minimizing the disruptive effect of climate change on viticulture by applying adapted technologies

Abstract

The research was conducted within SCDVV Bujoru, Galati county in the climatic conditions of the years 2012 to 2013. Experienced technological factors (soil system maintenance and fruit load) differentially influenced the intensity of physiological and biochemical processes with direct consequences for grape production and quality. A stronger positive influence on the production of grap, to exercise maintenance system, ground biggest productions were obtained when total mulching with straw. High temperatures combined with poor rainfall during the growing season and diurnal average consumption vine led to soil moisture differentiated soil in system maintenance. In a dry year, grape production was influenced by soil maintenance system, the maximum yield for variant partial mulching. In a normal year in terms of climate stands out partial mulching option, followed by mulching total. Systems maintenance of soil by mulching (total or partial) and minimum tillage exerted a positive influence on the quality of grape production. The reduction of the load of the fruit (20 and 40%) resulted in the maintenance of the systems of the soil to increase the content of sugar in the grapes and a decrease in acidity of the must, which yielded high values of the index gluco-acidimetric, adverse obtaining quality wines and typical.
