【摘要】：利用宁夏贺兰山东麓酿酒葡萄种植区2008~2016年4~5月逐小时最低气温资料,根据酿酒葡萄霜冻气候指标统计了不同程度霜冻日的出现时间。采用气候统计方法,研究了近9年来宁夏贺兰山东麓酿酒葡萄种植区不同程度霜冻出现情况及出现日期分布特征。结果表明:2008~2016年红寺堡种植区出现霜冻日数最多,其次是青铜峡种植区、银川种植区,石嘴山种植区出现霜冻日数最少。各种植区出现的霜冻日中均是轻度霜冻出现次数最多,其次是中度霜冻,重度霜冻日数最少。总体来看各种植区不同程度霜冻出现日期都集中在4月,且在4月上旬出现日数最多,只有红寺堡种植区霜冻日一直持续到5月中旬,5月下旬均未出现霜冻日。本研究结果对防止葡萄春冻灾害发生、提高葡萄成活率有现实意义。
[Abstract]:Based on the hourly minimum temperature data from April to May in the eastern foot of Helan Mountain of Ningxia from April to May 2016, the occurrence time of different degrees of frost days was counted according to the climate index of wine grape frost. The occurrence and date distribution of frost in wine grape growing area in the eastern foot of Helan Mountain in Ningxia in recent 9 years were studied by means of climate statistics. The results showed that the number of frost days was the most in Hongsibao planting area in 2008 / 2016, followed by Qingtong Gorge planting area, Yinchuan planting area and Shizuishan planting area. The number of frost days in all kinds of planting areas was the most, followed by moderate frost, and the number of severe frost days was the least. On the whole, the frost occurrence dates of different degrees in various planting areas were concentrated in April, and the number of frost days occurred in the first ten days of April. Only the frost days in Hongsibao planting area lasted until the middle of May, and no frost days occurred in late May. The results of this study are of practical significance to prevent the occurrence of spring freezing disaster and improve the survival rate of grapes.
