摘要
青杄是山西省次生天然林区的主要树种,笔者以2年生青杄苗为试验材料,采用遮阳网控制光照强度,进行不同光照强度下青杄苗高生长和地径生长量试验,结果表明,不同光照强度对栽植1个月后的青杄苗高生长和地径生长影响均不显著。
Relationships of light intensity, seedling height and diameter growth of two-year old Picea wilsonii were studied with implementation of artificial light condition using shade net. Results showed that there was no significant difference on growth of Picea wilsonii under different light intensity.
