霜冻对广元市黄葛树危害的调查分析

Investigation and Analysis of the Damage of Frost to Ficus virens in Guangyuan City

  • 摘要: 通过对广元城市园林绿化中黄葛树的受害情况进行调查分析,可为科学合理地预防和降低霜冻损失提供一定的参考依据。本文分析了1998年~2014年间广元城市及近郊园林绿化的黄葛树受冻害的情况,并对受害程度与栽培区分布和极端低温进行了统计分析。结果表明:自1998年黄葛树作为广元市园林绿化植物栽培后,其总体趋势为适应性逐年增强,受冻害的比例逐年降低。不同栽培片区的黄葛树受冻害的严重程度依次为:万源和下西片区 > 东坝片区 > 南河和上西片区 > 老城片区。

     

    Abstract: To provide a reference for scientifical and reasonable preventing and reducing damage of frost freezing to Ficus Virens (F. Virens), analysis was made of the freeze injury of F.virens from 1998 to 2014.Some statistic analyses were used to study the degree of freeze injury, cultivation region and extremely low temperature. The results were as follows.F.virens enhanced the adaptability to frost and the proportion of freeze injury decreased year by year. Based on the degree of freeze injury, there was a declining trend in the order of Wanyuan and Xiaxi region > Dongba region > Nanhe and Shangxi region > Old town region.
