山楂花盛花期与气象因子相关性研究

Study on the correlation between flowering period of hawthorn flower and meteorological factors

清河县马屯一带是中国北方平原地区山楂种植规模最大、最集中的区域,面积达2万多亩,被国家有关部门授予“中国山楂之乡”、“无公害山楂种植基地”等称号,每年的4月下旬到5月上旬为清河县山楂花盛开的日期,但具体的开花日期受温度、积温等多种气象要素影响,笔者利用2015-2018年近4年的气象资料对山楂花的盛花期进行相关性分析及积温指标确定,最后发现大于5℃积温稳定通过435.9℃为山楂花盛花期开始之日,这项结论对于一年一度的“清河山楂花节”活动的召开起到很好地指导作用。

Total Ma Tun area is the north China plain area hawthorn planting the largest and the most concentrated area, an area of 20000 mu.
