Experiment on Selection of Tree Species on Dachen Islandsof Taizhou

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.
