摘要
通过几年来牡丹开花物候期２月至４月温度的观测与分析，探讨了牡丹开花物候期与旬平均气温、有效积温间的关系，并摸拟了２月１０日后各物候期发育天数与其有效积温间的幂函数曲线模型。
This paper delt with the relation between peony florescence and ten-day average, effective temperature which was from February to April for several years. The power function about developmental days after 10, February and effective cumulative temperature was established, which laid fundament for controlling the peony flowering.
