古槐迁地保护移植关键技术及复壮研究

Experiment on Key Techniques and Rejuvenation for Ex-situ Conservation of Ancient Sophora japonica

摘要: 古树保护性移植是一项综合性、系统性的工程，其移植技术含量高，操作难度大，各工作环节都要严格遵循正确的操作技术流程。总结了2022 年12 月中旬至2023 年1 月中旬对北京市东城区两株古槐Sophora japonica 移植前的现场调研、人员和材料准备、树木雷达波探根、应力波枝干空洞检测、新型井字形工字钢托架吊运以及移植后复壮等关键技术要点，保证了古槐移植的成活及施工安全。结果表明，移植前的充分准备、先进诊断技术及可操作性强的施工工艺，是保证古槐移植成功的关键，为古树依法迁地保护提供重要的技术参考。

Abstract: Presentations were made on investigation, personnel and material preparation, root detected by tree radar waves, trunk detection by stress wave, preparation of I-beam bracket lifting, as well as rejuvenation technique for ex situ conservation of two ancient Sophora japonica in Beijing. The results indicated that sufficient preparations ensured the success of transplantation of the two ancient trees.
