摘 要:在全面调查泰安现存银杏古树的基础上,分析影响其健康生长的关键因素,针对不同损伤类型开展复壮技术研究。泰安银杏古树共49株,54%的古树生长良好,38.5%处于亚健康状态,7.7%处于濒危状态。其中衰弱古树损伤部位主要集中在根系、主干,表现为根系腐烂、主干木质部裸露或空洞。松烟墨液树干防腐和幼树靠接更新根系技术,复壮效果明显。On the basis of complete survey of existing ancient ginkgo trees, important factors of influence healthy growth was analysed. According to injury types, the rejuvenation technique had been studied on the unhealthy trees. There were 49 ancient ginkgo trees, 54 percent of these trees grew well, 38.5 percent were in sub-health, 7.7 percent were endangered. The damage positions of the trees centred on the roots and main trunk, mainly manifested as roots rotting and bare xylem and cavity of trunk. Spraying ink of pine soot to prevent trunk rotting and grafting young trees to renew roots could rejuvenate ancient ginkgo trees.
