摘要
利用2001～2008年宁夏酿酒葡萄的产量资料以及同期气象观测资料,分析温度、日照、降水等主要气象因素对葡萄产量的影响。结果表明:葡萄萌芽期、开花期、果实膨大及成熟期等关键生育期的温度对葡萄产量有明显的影响;日照偏多时会因阳光过于强烈而对葡萄果实产生灼伤而成为葡萄减产的因素之一;4月下旬和7月下旬降水量过多会造成葡萄减产,5月中旬的降水可以有效补充春季土壤水分的不足,对葡萄苗期生长有利。
Based on wine grape yield data and meteorology observations from 2001 to 2008 in Ningxia,the effects of temperature,sunshine hours and precipitation on wine grapes yield were analyzed in this paper.The results indicated that ≥10 ℃ accumulated temperature in growth season,temperature in the key growth periods such as germination stage,flowering stage,fruit mature stage,etc.had obvious influence on wine grapes yield.When sunshine was too strong,the grape output was reduction because of grape fruit hurt by strong sunlight.More rainfall in the late April and July could lead to reduction of grape output,and rainfall in mid-May could complement efficiently shortage of soil moisture,which was favorable to growth of grape in seedling stage.
