摘　　要：珙桐是国家Ⅰ级重点保护珍稀野生植物,是四川峨眉山、华西雨屏带南部常绿落叶阔叶混交林的重要建群种之一,具有较高的生态价值。随着区域开发项目的增多,致使桐的天然分布面积和种群数量下降,开展珙桐保护性移栽技术研究,有利于缓解发展和保护之间的矛盾。通过对珙桐保护性移栽的移栽前、移栽过程、移栽后管护的技术实践,以及紧急移栽、因特殊生长环境无法带土球移栽的处理方法进行探讨,总结出一套桐保护性移栽技术,也可为类似保护植物保护性移栽提供参考。Davidia involucrata is one of the important constructive species of evergreen and deciduous broad-leaved mixed forest in Emei Mountain of Sichuan Province and the South of Yuping Belt of Western China,which is a national key protected rare wild plant with high ecological value.With the increase of regional development projects,the natural distribution area and population number of Davidia involucrata decreased.The research on protective transplanting technology of Davidia involucrata is conducive to alleviating the contradiction between development and protection.A set of protective transplanting technology of Davidia involucrata was summarized through the discussion on the technical practice of pre-transplanting,transplanting process,and post-transplanting management of protective transplanting of Davidia involucrata Prefecture,as well as the treatment methods of emergency transplanting and soil ball transplanting due to special growth environment,which provided reference for protective transplanting of other protective plants.
