摘要
通过对不同林分密度下木荷人工林的生长情况对比分析,结果表明:在7年生时,造林密度对木荷树高、胸径、材积等生长量没有显著影响,但对其保存率和蓄积量有较大影响,以初植密度3 330株·hm^(-2)和1 995株·hm^(-2)为最好,其保存率分别为89.4%和88.0%,蓄积量分别为8.99和5.62 m^3·hm^(-2)。
The growth of Schima superba plantation were analyzed under different stand densities.Result show that at 7 years of age,the density has no significant effect on the growth of tree height,DBH,volume of Schima superba;the density of Schima superba has a great influence on preservation rate & stock volume.The initial planting density of 3 330 trees hm^-2 and 1 995 trees hm^-2 is the optimal.The preservation rates are 89.4%& 88.0%,respectively,and the growing stock is 8.99 & 5.62 m^3 hm^-2 ,respectively.
