摘要
以位于浙江省云和县、遂昌县、龙泉市和开化县等地的越南安息香(Styrax tonkinensis)人工林为研究对象,系统研究其人工林生长情况,并利用优势木对比法进行了优树早期选择。结果表明,在云和、遂昌和龙泉3个试验点,4年生越南安息香的胸径、树高和材积等性状均显著或极显著高于对照树种,但以遂昌点试验林为最好,其胸径、树高和材积均值分别为7.47 cm、6.95 m和0.015 9 m3。在对5年生试验林全面踏查的基础上,综合考虑数量性状与质量性状,分别为开化、遂昌和龙泉三地初选出优良度高、形质指标好的KH-03C、SC-01C和LQ-02C等材用优树6株,为开化、遂昌和云和三地初选出KH-05Y、SC-01Y和YH-02Y等油用优树12株。
Study was conducted on growth of Styrax tonkinensis plantations in counties of Yunhe,Suichang,Longquan and Kaihua,Zhejiang province,and plus trees were selected by dominant comparison method.The result showed that height,DBH and volume growth of 4-year S.tonkinensis in Yunhe,Suichang,Longquan was higher than that of the control,especially at Suichang,with DBH,height and volume of 7.47cm,6.95m and 0.0159m3.Based on investigation of 5-year plantations and consideration of quantitative and qualitative characters,6 plus trees for timber were primarily selected for Kaihua,Suichang and Longquan,12 plus trees for oil were selected for Kaihua,Suichang and Yunhe.
