摘　　要：连续6年对裸地生境刺五加的物候观测、生长发育性状观察,结果表明：裸地生境下刺五加株高随年龄的增长而增高,低龄阶段（1-6年）株高与年龄之间是呈成正相关。刺五加地径随年龄的增长而增大,株高与地径二者呈相同变化趋势。裸地生境下刺五加植株的分枝数和冠幅随年龄的增加而呈增大的关系。裸地生境刺五加分枝能力增强。冠幅随年龄的增长而不断地增大,低龄（1-5年）刺五加冠幅增长较快。Observed the growth and development trait of Acanthopanax senticosus in farmland through consecutive 6 years, the results showed： the height of Acanthopanax senticosus in farmland increased with age, at young stage （1-6 years） height and age was between a positive correlation. Collar diameter growth of acanthopanax senticosus increased with age, height and collar diameter showed the same trend. The branch number and crown width ofAcanthopanax senticosus in farmland increasing with age. branching capacity of Acanthopanax senticosus enhanced in farmland, crown width increased with age, growing fast at young stage （1-5 years）.
