摘 要: | [目的]探讨影响灵武长枣生长的主要气象灾害。[方法]通过对历年灵武长枣产量与气象因子的统计分析,研究灵武长枣不同生长阶段气温、降水、相对湿度等因子对产量的影响。[结果]影响灵武长枣产量的主要气象灾害是盛花期出现连续9d以上≥30℃的高温天气、成熟期连续10d以上阴雨天气,盛花期连续7d以上阴雨天气以及越冬期出现4d以上≤-22℃的持续低温天气,同时极端最低气温达到-24℃。[结论]灵武长枣不同生长时段主要气象灾害不同。出现最多的主要气象灾害是盛花期连续9d以上≥30℃的高温天气。

Abstract: | [Objective] The research aimed to explore the major meteorological disasters impacting on the growth of jujube fruits. [Method] By analyzing statistic characters of meteorological data and historic yield data of jujube fruits,the influence of yield of jujube fruits with different factors was studied such as temperature,precipitation,relative humidity in different terms. [Result] The major meteorological disasters which impact the yield of jujube fruits are ≥30 ℃ continuing over 9 days at full bloom stage,the continuous rainy weather continues over 10 days at mature stage,the continuous rainy weather continues over 7 days at full bloom stage,≤-22 ℃ low temperature continues over 4 days and the minimum temperature reaches-24 ℃ at over wintering stage. [Conclusion] The major meteorological disasters which impact jujube fruits are different at different stage. The major meteorological disaster occurring max times is ≥30 ℃ high temperature which continues over 9 days at full bloom stage. |
