台州市大陈岛海岛困难地引种8个树种造林试验

Experiment on Selection of Tree Species on Dachen Islandsof Taizhou

    摘要
  • 摘要: 大陈岛为浙江省台州列岛之一，存在生态系统脆弱，造林成活低、树木生长困难和树种单一等问题。选择天竺桂Cinnamomumjaponicum，红楠Machilusthunbergii，舟山新木姜子Neolitseasericea，乌桕Sapiumsebiferum，台湾相思Acacia confusam，红叶石楠Photinia×fraseri，湿地松Pinuselliottii和枫香树Liquidambar formosana 8个树种，对其在大陈岛造林后的成活率和保存率及生长状况进行了5年的观测，为大陈岛筛选出适宜作为沿海防护林的树种。结果显示，造林5年后（2017年），红叶石楠、乌桕、枫香树的保存率皆在82%以上，其树高分别为437.3 cm、437.9 cm和412.7 cm，地径在7.6 ~ 8.0 cm。研究结果表明，红叶石楠、枫香树、乌桕是海岛地区造林的首选优良树种，而红楠、普陀樟、舟山新木姜子可作为重要推荐树种，湿地松可作为备选树种，台湾相思不适宜在大陈岛海岛造林。

     

    Abstract: In 2012, 2-year Cinnamomumjaponicum, Machilusthunbergii, Neolitseasericea, Sapiumsebiferum, Acacia confusam, Photinia×fraseri, Pinuselliottiiand Liquidambaformosanaseedlings were selected for afforestation experiment in DachenIslands of Taizhou, Zhejiang province.Investigations were carried out on survival and preservation rate of seedlings after plantation.The results showed that 3 months later, the survival rate of P.×fraseriL.formosana,P.elliottiiand S.sebiferumwas more than 94%, and lowest was that of A.confusam, only 83%.The preservationrate of P.×fraseri, S.sebiferum andL.formosanawas more than 82% 5 yearslater.Theirtree height growth was437.3 cm, 437.9 cm and 412.7 cm respectively, with ground diameter of 7.6-8.0 cm.The experiment demonstrated that P.×fraseri, S.sebiferum and L.formosanawas the first choice for afforestation in DachenIslands.While M.thunbergii,C.japonicumand N.sericea could be recommended for plantation, and A.confusamcould not tolerate coldness, and was not suitable for afforestation.
