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.
