摘要
对3种抚育方式下(2∶2∶1、2∶1∶1和2∶1)杂种落叶松的成活率及生长量进行调查分析的结果显示:3种抚育方式下杂种落叶松的造林成活率及保存率只有2∶2∶1超过了90%,抚育方式对杂种落叶松幼龄期间的地径及苗高生长量的影响比较明显,对平均胸径的影响也比较显著。
The survival rate and growth of the Hybrid Larch in three tending mode （ 2： 2： 1, 2：1 ： 1 and 2： 1）were investigated. The results showed that the survival rate and preservation rate of the Hybrid Larch were more than 90% only in 2： 2： 1, and the influence of tending modes on the ground diameter, the high growth and the DBH were all significant, the growth of hybrid larch in the mode of 2： 2： lwere the best, the second place was 2： 1： 1, and 2：1 was the worst.
