对多年多点有年重复的试验（时间超过１／２轮伐期）进行研究，评选出广西融水等１５个高产种源，材积遗传增益９．０５％—３３．０６％，其中省内种源８个，表明福建省杉木优良种源表现突出。福建省杉木优良种源区的轮廓界线是以武夷山杉岭的东南、博平岭北端、戴云山西北和鹫峰山以西所包围的地带。尤以闽江上游富屯溪、沙溪、建溪三支流中下游流域地区的海拔４００ｍ以下谷地丘陵地带的种源，增产趋势更为明显。我省杉木造林应优先选择本省优良种源，材积遗传增益可达０—４０％，分别对省内杉木三大产区提出应推广的优良种源；同时，对在我省表现突出的广西融水、贵州锦屏种源所代表的南岭西部融江、都柳江、清水江流域的种源，要适当引进。
After repeated experiments for more than a year and more than 1/2 rotation time, 15 high-yielding provenances such as Guangxi Rongshui were selected and their genetic gain was 9.05% -33.06% Eight provenances, indicating that Fujian Province outstanding provenance provenance. The outline of the provenance region of Cunninghamia lanceolata in Fujian Province is located in the southeastern part of Wuyishan cedar ridge, the northern tip of Mount Boping, the northwest of Mount Daiyun and the west of Jiufeng Mountain. Especially in the upper reaches of the Minjiang River Fu Tunxi, Shaxi, Jianxi three tributaries of the lower reaches of the basin area elevation of 400m below the hilly areas of provenance, increasing production trends even more apparent. In our province, afforestation of Chinese fir should give priority to selecting superior provenance in this province, with the genetic gain of 0-40% of the total volume, providing excellent provenances for the three major producing areas of Cunninghamia lanceolata in China. Meanwhile, Water, Guizhou Jinping provenance represented by Nanning Western Rongjiang, Du Liujiang, Qingshui River Basin provenance, to be properly introduced.
