Abstract: In order to understand the effects of meteorological factors in southern Xinjiang on fruit quality of Jun jujube, this paper analyzed the temperature, amount of sunshine, rainfall, relative humidity and wind speed, etc. meteorological data from 2015-2016 in Akesu, Khotan and Korla 3 areas, and studied the function law of climate changes on fruit quality. It was found that climate conditions in southern Xinjiang had obvious effects on fruit quality of Jun Jujube, through comparison of 12 meteorological factors on single fruit weight, Vc and soluble sugar contents, etc. fruit qualities. The results showed that the key factors affecting Jun Jujube quality were average temperature, average maximum temperature, sunshine hours and precipitation. The contents of Vc and total soluble sugar were most significantly affected by average minimum temperature.

Key words: Jun Jujube, southern Xinjiang, eteorological factor, fruit quality

摘要： 为了了解新疆南疆地区气象因子对骏枣果实品质的影响，分析了2015-2016年南疆地区阿克苏、和田及库尔勒三个地区的温度、日照量、降雨量、相对湿度和风速等气象数据，研究了气候变化情况对骏枣果实品质的作用规律。通过对比两年内12项气象因子对单果重、Vc和可溶性总糖含量等骏枣果实品质的影响，发现南疆气候条件对骏枣果实品质有明显影响，不同品质指标的气象影响因子有所不同。结果表明对骏枣品质的关键指标（单果重、蛋白质、Vc和可溶性总糖含量）影响较大的气象因子分别为平均气温、平均最高温度、日照时数和降水量。其中Vc和可溶性总糖受空气平均最低温度的影响最明显。
