采用2000-2012年鄱阳湖旅游地区的8个农业气象观测站资料,利用聚类分析、有效积温法则及变异系数统计等方法,研究鄱阳湖旅游地区油菜花花期特征及其预报. 结果表明,鄱阳湖旅游地区纬度越高,开花越晚,始期与盛期之间的时间越短. 开花始期、普期及盛期的平均日期分别为3月5日、11日和17日. 始期-普期、始期-盛期的平均间隔分别为5. 3 d、13 d. 有效积温方法预报婺源油菜花各花期较稳定,以现蕾为起始点,开花始期、普期及盛期的平均有效积温值( >0 ℃)分别为236. 50 ℃、305. 21 ℃和379. 55 ℃.

Based on the cluster analysis method, rule of effective temperature summation and CV methods the 2000-2012 observation data from 8 agrometeorological stations in tourist region of Poy-ang Lake are used to analyze the rape flower florescence characteristics and its tourism forecast. The results show that the higher latitude is,the later florescence is. The higher latitude is,the shorter the interval between fist bloom and full bloom is. General average florescence dates were separately march 5 th ,11 th and 17 th form first bloom to full bloom. The average intervals from first bloom to gener-al bloom and that from first bloom to full bloom were separately 5. 3 d and 13 d. The conclusion of florescence prediction in Wuyuan is relatively stable by rule of effective temperature summation. As a starting point in the bud stage,the average effective accumulated temperatures ( >0 ℃) were sepa-rately 236. 50 ℃,305. 21 ℃ and 379. 55 ℃ form fist bloom to full bloom.
