[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. 展开更多
