伊犁种植鲜食、酿酒葡萄气候适宜性分析

Wine-grape growing in Ili region

通过对伊犁气候资源与国内外著名葡萄产区气候等生态因子对比分析表明,影响伊犁鲜食、酿酒葡萄发展的气候因子有温度、光照、降水量、日较差等。伊犁葡萄果实成熟期8、9月份有效积温1992.9℃,水热系数K值0.2-0.4,K<1.5,日光能系数IH值6.9,IH>4.5,气候条件指标接近或超过国内外优质葡萄产区,具备生产优质鲜食葡萄和酿酒葡萄所需的气候条件,属优质葡萄产区。

The weather conditions in Ili region were compared with those of some famous grape - production area at home and abroad. The results indicated that weather factors such as temperature, light, amount of falling water, diurnal temperature range are the most important factors which affected the development of table grape and wine grape growing in Ili region. During the period of grape ripe maturing, the efficient accumulated temperature arrived to 1 992.9℃ , coefficient of lights and calories is 0.2-0.4 under 1.5, coefficient of sunlight is 6.9 higher than 4.5. The index of weather condition is little higher or higher than that of other high - quality grape production area. Therefore, the area with very good weather conditions to grow high - quality table grape and wine grape are the high - quality grape production area.
