低温冻害对抚顺新宾蓝莓开花期的不利影响浅析

A Preliminary Analysis on the Adverse Effects of Low Temperature and Freezing Injury on the Flowering Period of Fushun Xinbin Blueberry

利用2016—2020年5月中下旬新宾国家基本气象站、北四平乡区域站的气象资料以及抚顺市新宾满族自治县北四平乡蓝莓种植基地统计资料,分析了低温冻害对蓝莓开花期的影响,并研究能否利用新宾县城镇天气预报提前预测冻害并采取措施加以防范。结果表明:新宾国家基本气象站与北四平乡区域站日最低气温成正相关,当新宾国家基本气象站最低气温低于5.29℃时北四平乡最低气温可低于2℃从而发生低温冻害,降低蓝莓花授粉率,甚至冻死花苞花芽,直接降低蓝莓产量,对此可通过提前熏烟大大减轻低温冻害对蓝莓的影响。

Using the meteorological data of Xinbin National Meteorological Observing Station and Beisiping Station and the statistics of the blueberry base in Beisiping,Xinbin Manchu Autonomous County,Fushun City,analyzing the influence of low temperature and freezing injury on blueberry flowering period studied if the weather forecast can be used to predict the occurrence of freezing damage and take measures to prevent it in advance.The results showed as follows:There was a positive correlation between the daily minimum temperature of Xinbin National Meteorological Observing Station and Beisiping Station.When the minimum temperature of Xinbin National Meteorological Observing Station was lower than 5.29℃,the lowest temperature in Beisiping Station could be lower than 2℃,it led to low temperature and freezing injury,reduced the pollination rate of blueberry flowers,cut down the yield of blueberry directly.The effect of low temperature and freezing injury on blueberry could be greatly reduced by smoking in advance.
