摘要: 通过对河南大别山引种鹅掌楸试验观察,鹅掌楸年生长过程中,树高有1个生长高峰,胸径有2个生长高峰;幼林阶段树高生长较快,前12a的年均生长量在1m以上,生长高峰期出现在第4年,年生长量1.65m;胸径生长速生期为前10a,从第2年开始,即进入生长高峰,年生长量达到1.2cm以上,一直持续至第10年;在前18a,材积增长一直处于上升阶段,并随树龄增大而加快,18年生时,还未见有减慢现象。鹅掌楸树高、胸径、单株材积呈Logistic增长。

Abstract: Observations on Introduction Liriodendron Chinese in Henan Dabei Mountain, on the annual growing pattern, the results show that during the growth period there is one of height accretion ,two peaks of DBH, that height growth was quick during young. The mean height growth of the first 12years reached 1m/year, the peak period at the fourth year with the increment of 1.65 meter/year the peak period of DBH at the second year which will last for 10 years, Volume increment will last more than 18 years. the growth DBH and Volume growth followed logistic curve.
