摘要:
基于逆序积温方法，利用河北省唐山市丰润区“牛妈妈枣”2013～2018 年始花日观测资 料和丰润区2012～2018 年逐日平均气温气象观测资料，对“牛妈妈枣”始花日与温度的关系进行 了分析。结果表明，日平均气温达到19℃时，“牛妈妈枣”开始开花；始花日与前期24～26 天（4 月中旬左右）积温呈显著相关；始花日与始花前272～283 天（8 月中下旬）积温的相关系数较稳 定，呈显著负相关。比较而言，“牛妈妈枣”始花日与≥0℃积温总体上具有较高的相关性。
Abstract:
Based on the reverse order temperature method, the relationship between the flower day and temperature of "mother jujube" in fengrun district of tangshan city, Hebei province, was analyzed by us? ing the data from 2013 to 2018 and the daily mean temperature meteorological data from 2012 to 2018. The results showed that when the average daily temperature reached 19 °C, the "cow mother dates" be? gan to bloom; The initial flower day was significantly related to the accumulated temperature of the pre? vious 24 to 26 days(around mid-April); The correlation coefficient between the initial flower day and the first 272 to 283 days(mid-to-late August) was relatively stable and showed a significant negative correlation. In comparison, there is a high correlation between the beginning date of "cow mother ju? jube" and ≥ 0 °C accumulated temperature.
