摘要
本文用lgistic方程模拟树种生长过程,确定了10个树种的速生期并划分出短速型、持续型和中间型3个高生长类型。根据生长和平茬效果,选择了沙棘等7个抗旱及萌蘖性强、较速生的能源林树种。
Determines the rapid height growth period of 10 energy plantation species by simulation of growth period with Logistic equation. They are classified into 3 height growth types, e. g. short-term rapid growth type, long-term rapid growth type and intermediate type. 7 species including sea black locust were selected for energy plantation according to their drought tolerance and vigorous sprouting ability.
