摘　　要：[Objective] The aim was to research annual shoot increments, blooming and fruit-bearing times, and sprouting ratio of man-made Phoebe boumei.[Methed] Phenological observations of Phoebe boumei blooming were conducted as per method of phytocoenology. [Result] Phoebe bournei shot three times per year, and autumn shoots proved the largest, followed by summer shoots and spring sprouts. Sprouts shaped from late April to early May, and bloomed from late April to middle May; young fruits grew from middle May to late May and matured from middle De- cember to late December. Thousand-seed weight of fruits reached 487-503 g, and averaged 496 g; thousand-seed weight of seed was 265-275 g and averaged 269 g; sprouting rate of seed in room was in 84.8%-88.5% and averaged 86.5%; sprouting rate of seeds in fields was in 68.4%-72.6%, and averaged 70.4%. [Conclusion] The research provides references for man-made Phoebe bournei forests.[目的]研究闽楠人工林年枝梢生长量、开花结实时间、种子发芽率。[方法]采用植物群落学调查方法。进行闽楠开花结实等物候学观测比较。[结果]闽楠一年抽3次梢，秋梢生长量最大，其次为夏梢，春梢最小。闽楠花芽形成在4月下旬～5月上旬．开花在4月下旬-5月中旬,幼果形成在5月中旬～5月下旬，果子成熟在12月中旬-12月下旬。闽楠林果实的千粒重为487-503g，平均496g；种子千粒重为265-275g，平均269g；种子室内发芽率为84．8％-88．5％．平均86．5％；田间发芽率为68．4％-72．6％，平均70．4％。[结论]为提供闽楠人工造林基础性资料提供参考依据。
