根据扩张相对生长式 ,利用 6年生密度试验林调查资料 ,探讨初植密度与最大树冠长、最大树冠长树高之间的关系。结果表明 ,通过最大树冠长和最大树冠长树高可以管理林分密度 ,并提出合理的间伐时间
According to the relative growth type of expansion, the relationship between planting density and the maximum canopy length and the maximum canopy height was studied by using the data of 6-year-old density test forests. The results showed that the density of canopy was managed by the maximum canopy length and the maximum canopy height, and the reasonable time of thinning
