摘要: 采用2011—2019年咸宁市葛仙山景区野生樱花9年的花期调查资料和临近区域气象站同期的观测资料,根据作物发育积温基本恒定的理论,利用阶段积温法则、双尺度递推及离散系数统计等方法,分析研究葛仙山景区原生态樱花群落的花期特征及其积温预报指标。结果表明,葛仙山景区樱花的始花期、盛花期的平均日期分别为3月11—12日、3月15—16日, 始花期-盛花期的平均间隔为4~5 d。阶段积温方法预报景区樱花的始花期和盛花期的指标为从1月11日起,≥1.1 ℃的阶段积温分别为316.8、369.7 ℃,该指标预报花期误差平均为2~3 d。

Abstract: Using the nine years of flowering survey data of wild flowering cherry in Gexianshan scenic spot of Xianning city from 2011 to 2019 and the observation data of the adjacent area meteorology station in the same period,the flowering characteristics and the accumulated temperature forecast indicators of the original ecological flowering cherry community in Gexianshan scenic spot were analysed according to the basic theory of constant accumulated temperature of crop development, using the phase rule of accumulated temperature, double scale statistical recursive generalized discrete coefficient method. The results showed that the average dates of the initial time of flowering and the full-bloom stage of flowering cherry in Gexianshan scenic spot were March 11 to March 12 and March 15 to March 16, respectively, and the average interval of the initial time of flowering and the full-bloom stage was 4~5 days. The florescence index of flowering cherry in scenic spot were since January 11, ≥1.1 ℃ phase accumulated temperature of 316.8 ℃ and 369.7 ℃ respectively by the stage accumulated temperature method. The mean error of this index in predicting flowering was 2~3 days.
