摘  要：
通过对人工杉木林内18a散生檫木生长规律的调查研究,表明檫木在幼龄林8a以前阶段生长稍微较慢,中林龄阶段进入生长旺盛期。树高在第11～18a间生长均处于高峰状态,年均达0.9m以上;树高连年生长量在第8～14a间都处于1.0m以上生长状态。平均胸径在第11～18a间年均生长量在0.9cm以上,保持了较长时间的快速生长;胸径连年生长量在第8～13a间保持1.01m以上生长高位。单株材积幼林龄林阶段生长缓慢,在中林龄阶段持续快速生长,从第11年开始连年生长量均达到0.01m3以上。散生檫木形成杉木与檫木混交是经典的混交模式,两树种共生互惠关系,充分地激发了檫木速生的优良特性。

摘  要：
The investigation and Study on the growth regularity of sassafras scattered for 18 years in Chinese fir plantation showed that the growth of sassafras was slightly slower in this stage before 8 years in the young forest,and the growth of sassafras in the middle stage entered the peak period. The average tree height was in the peak state from 11 to 18 years,with an average annual growth of over 0.9 m,and the continuous annual growth of tree height was above 1.0 m from 8 to 14 years. The average annual growth of DBH was above 0.9 cm during the 11-18 years, and the annual growth of DBH was above 1.01 m during the 8-13 years. The growth rate of young stand with single volume was slow at the stage of young stand,and it continued to grow rapidly at the stage of middle stand,and the annual growth rate was above 0.01 m3 from the 11 th year. It is a classical mixed mode that scattered Sassafras form Chinese fir and sassafras. The symbiotic and reciprocal relationship between the two species fully stimulates the excellent characteristics of sassafras fast-growing.
