气候变暖对贺兰山东麓酿酒葡萄热量资源及冷冻害的影响
Impact of climate warming on heat resources and freezing injuries in wine grapes at the east foot of the Helan Mountains of Ningxia
摘要
Abstract
Using meteorological data collected from the east foot of the Helan Mountains of Ningxia since 1981,we analyzed the impact of climate warming on heat resources and freezing injuries in wine grapes.The results show that the average temperatures from April to September increased significantly during this period,with an abrupt climate warming trend beginning around 1997.Temperature anomalies were higher than 1℃ in some years after 1997.The trend of average temperatures in April,when wine grapes are in their bud germinating stage,increased rapidly,but there were also greater fluctuations,and the risk of frost or of strong cooling periods also increased.Low-temperature injury events were more likely to appear between July and August,which is the period during which wine grape berries grow and mature.With the active accumulated temperature above 10℃ increased significantly,the probability of mid-or late-maturation was 100％,and the probability of temperatures of 3300℃ (the critical value of high maturity and quality) between April and September improved.With the frost-free period was prolonged the probability of late-maturation increased;the accumulated temperatures and frost-free periods could result in extreme late-maturation trends in many years.The factors affecting low temperature freezing-disasters in winter had no distinct trend.As the number of sustained days at which the minimum temperature dropped below-17℃ (the freezing-disaster critical temperature) decreased,the extreme minimum temperature was raised,although it was still below-17℃,and the days at which the minimum temperature was lower than-4℃ at a depth of 20 cm decreased in Huinong,Helan,Pingluo,and Yinchuan.The frequency of frost appearing after the appropriate time in spring was also reduced,but the number of days with frost increased.Although the minimum temperature decreased,Both the years and days with frost appearing after the appropriate time in spring increased.Climate warming has both advantages and disadvantages for wine grapes,and different cultivars adapt to these effects differently.Thus,there is still a need to increase monitoring of temperature and to prevent extreme climate events and meteorological disasters during the key periods of wine grape development in order to reduce or avoid the negative effects of climate change on wine grapes.关键词
