Agroclimatic Assessment of Wintering for Fruit Growing Cultures

Abstract

 Except by temperature conditions and the moisturasation in the period of active vegetation the development and formation of production of fruit trees is determined by the meteorological conditions during the winter, which can cause serious damage to the agricultures. The long-term fruit trees are subject to the influence of low temperatures and strong cold winds, which are characterized by the usage of agroclimatic indicators. The indicators for evaluation of the conditions through the winter on the basis of different temperatures are determined – the absolute minimum temperature, the average minimal temperature, the average month temperatures for the winter, the lowest temperature in the coldest month, their continuation and repeat sequence in the period 2000 – 2011 in Plovdiv.
