摘要:自1987年以来,在贫瘠立地上开展了大叶相思Nelder(放射型)密度试验,7年的研究结果表明,大叶相思的胸径、树高以及断面积×树高与初始单株面积的对数呈现向下的抛物线关系。在贫瘠立地上营造大叶相思,适当密植可促进林木胸径、树高的生长,以1m×2m或1.5m×2m等较小株行距为宜。对于不同初始密度的林分,随着年龄的增长,其林木生长差异最终呈现递减趋势。林分密度越大,其轮伐期亦越短。
Nelder trial of Acacia auriculaeformis A.Cunn. has been undertaken for seven years in barren site since 1987.It was shown that their diameter in breast height,tree height and basal area×height are relative to logarithm of area per tree in downward parabola.It′s suitable to select smaller spacing such as 1×2 or 1.5×2 meter etc.for planting A.auriculaeformis because it can accelerate the growth of diameter and tree height.For different types of forests with different initial density, the thicker the forest,the shorter the rotation age.
