檫树(Sassafras tzumu Hemel)为我国南方优良速生用材树种之一,前人对其进行了多方面的研究,但对于土壤物理性与檫树生长的关系的研究尚少。许多调查表明,在同一地区,尽管土壤的化学性质相似,而由于土壤容重不同,檫树生长 Sassafras tzumu Hemel is one of the fine species of fast growing timber in southern China. Many studies have been conducted on the species of Sassafras tzumu Hemel. However, there is little research on the relationship between soil physical properties and the growth of the tree. Many surveys have shown that in the same area, despite the similar chemical nature of the soils and the different tree species
