摘  要:
竹叶兰是具有重要药用、景观价值的国家II级保护植物,在完善其扩繁技术的基础上对其进行迁地保护和野外回归研究。结果表明,迁地保护的种群生长良好,并能形成景观效果。野外回归点分别为东莞金鸡嘴水库、深圳市梧桐山国家级风景名胜区和东莞水濂山森林公园,半年后成活率分别为20%、40%和20%,一年后成活率分别为13.33%、16.67%和6.67%,表现为野外回归时间越长,其成活率越低;株高差异表明梧桐山试验点的生长量最大;样地中整体分株能力和高位芽萌生能力都很低。同时提出竹叶兰野外回归地点的选择原则,以及清理周边禾本科、莎草科植物的地上部分等建议。

摘  要:
Arundinagraminifolia is endangered plant with important medicinal and landscape value.With thedevelopment of its propagation technology,the ex-situ conservation and reintroduction study began too.The populationof ex-situ conservation grew well and had a good landscape.The sites of reintroduction were Jinjizhui Reservoirs,Wutongshan National Park and Shuilianshan Forest Park.After half of year,the survival rate was 20%,40% and 20% respectively; afterone year,the survival rates were 13.33%,16.67% and 6.67%respectively.The longerthe reintroductiontime was,the lower the survival rate was.The highest biomasswas at Wutongshan test site.The population of reintroduction had the low rametcapacity and budsprouting ability.The selection principle of the reintroduction field was proposed,and the suggestions of clearing the Gramineae and Cyperaceae plants around the field were put forward.
