【摘要】 江西省于1976年和1979年两次参加全国性杉木地理种源全分布区试验。据27年、9年和6年生试验对比研究结果表明,幼龄期表现优良的种源到成熟期多数仍表现优良,说明了优良种源生产力具有较强的稳定性。根据27年生材料研究结果,福建建瓯、广东乐昌、广西融水等种源属于持续速生型,江西种源属于后期速生型。排在前9位的种源是:福建建瓯、广东乐昌、广西融水、江西安福、江西全南、江西铜鼓、浙江龙泉、四川雅安、贵州锦屏。更多还原

【Abstract】 Jiangxi Province attended national provenance trials of Cunninghamia lanceolata in 1976 and 1979,respectively.The results form comparison research on its forests aged 27,9 and 6 showed that the majority of provenance which behaved very well retained good behavior.It explained that the productivity of good provenance has a strong stability.According to the results from 27-year-old trial forests,Fujian Jianou,Guangdong Lechang,Guangxi Rongshui belonged to the provenance with continuous fast growth.The provenance of Jiangxi belonged to the provenance of fast growth later.There were 9 superior provenances such as Jianou Fujian,Guangdong Lechang,Guangxi Rongshui,Jiangxi Anfu,Jiangxi Quannan,Jiangxi Tonggu,Zhejiang Rongquan,Shichuang Yaan,Guizhou Jiangpin.更多还原
