摘要
在次生林带状改造中 ,经过方差分析表明 :选择 6m、 4m采伐带宽度对落叶松更新成活率效果较好 ;不同树种更新效果有所差别 ,落叶松成活率最高 ,生长情况也好于其它更新树种 ,各更新树种保存率差异并不显著。
In the course of secondary forest strip reform, the result of variance analysis shows that in the 6m-width and 4m-width harvesting strips, the surviving rate of larch is better. The regeneration effects of different species are different as follows: the surviving rate of larch is the highest, and its growth is better than other species. The discrepancy of conserving rate of all regenerating species is not significant.
