摘　　要：通过对古槐树的生长环境和生长状况的调查,并对植株叶片营养元素含量和生长地周边的土壤中营养元素含量进行定量分析,结果表明:土壤中的营养极度缺乏,根系得到的营养物质极为有限,这样,使根系无法生长,造成树体的伤害。在给古槐施用肥料中有必要增加N、P、Ca、Mg、Zn等营养元素,使古槐能更旺盛地生长。还对古槐树的保护和复壮提出措施,以期为延缓古树的衰老提供理论依据和切实可行的方法。The growing environment and status survey of the Ancient Sophora japonica L. trees, along with their analysis of leaf and soil nutrition contents around their growing area, were reported in this study. The results showed that the limited nutrition absorption restraint the growth and development of their roots of those growing in the extremely poor soil conditions in term of nutrition contents, which resulted in damages of the whole trees. This suggests that adding fertilizer containing necessary nutrition elements N, P, Ca, Mg and Zn might help recover the growth of these ancient trees. The theoretical and practical strategies and methodology of protection and recovery of the scholar trees in order to delay the tree senility were also discussed in this study.
