摘要
报道了岛屿濒危植物普陀鹅耳枥人工促成天然更新的技术措施及其初步成效,2018年、2019年连续2年成功获得天然更新后代,为该物种的保护提供了重要的技术支撑。总结人工促成普陀鹅耳枥天然更新的关键技术主要包括:(1)立地选择和微环境改造是前提。(2)人工种群营建是基础。(3)开展林分精心抚管和定向促成是关键。(4)持续系统的配套研究是保障。本研究成果只是初步结果,要想真正实现普陀鹅耳枥在没有人工干预下的种群自我维持和天然更新,仍有很多关键技术有待于进一步摸索研究。
The natural regeneration technologies of Carpinus putoensis, an island endangered plant by artificial promoting were reported in this paper. In 2018 and 2019, the seedlings by natural regenerating were found in the artificial population consecutively. Some key factors were summarized that including:(1) Site con-ditions selection and microenvironment transformation.(2) Artificial population construction.(3) Careful man-agement and directional promotion.(4) Systematic research. However, only preliminary results were revealed by this research. To realize natural regeneration and self-maintenance without human intervention, the further ex-ploration of technologies should be studied.
