对紫色土林地栽培的闽粤栲林分生长量、生物量、林分生长过程、空间分布等进行了分析研究。结果表明 :1 5年生闽粤栲平均胸径、平均树高、林分立木材积分别为 1 8 5cm、1 2 1m和 1 0 9 72 5 0m3 ·hm-2 ,生长量较高 ,是较好的速生用材造林树种。同时闽粤栲在紫色土林地还表现出 :侧根发达 ,分布较浅 ,根量减少 ,板根明显的特点 ,与红壤林地根系存在差异 ,说明其根系有较强的适应性
The growth, biomass, stand growth process, spatial distribution and other aspects of stand cultivation of purple soil in purple soil were analyzed. The results showed that the average diameter at the age of 5 years old, average tree height, stand height and stand volume were 1 85 cm, 1 2 1m and 1 0 9 72 50 m3 · hm-2, respectively. Growing afforestation tree species. At the same time, the flesh and thrips in Fujian purple soil also showed: the lateral root developed, shallow distribution, reduced root volume, root obvious characteristics, and the red soil forest root there is a difference, indicating that its roots have strong adaptability
