| 摘 要： | 采用广东、湖南和贵州3个省40个杉木优良无性系，于1998年在广东大坑山林场进行区域化试验。结果表明：6年生单株材积生长55％的无性系优于对照，其中达较显著差异水平以上的有4个无性系，广东3个，湖南1个。广东提供的无性系表现较好，其中生长表现较优的GDL041、GDL043、GDL044三个无性系单株材积达较显著差异水平以上，占参试无性系的33％，其次为GDL042、GDL046无性系，其单株材积增益均达25．1％以上，在本省亦经过了3次以上重复试验，表现均较优，可大面积在广东造林推广应用。 |

| Abstract: | The regionlization test of 40 Chinese fir clones come from Guangdong, Hunan and Guizhou province were conducted in Dakengshan Forest Farm,Guandong province. The results showed that 55 percent clones have better volume growth compared with the control at 6 years old, 4 clones have significent difference, 3 of them come from Guangdong, the other come from Hunan. Clones come from Guangdong have better performance than the clones come from the other 2 provinces. GDL041, GDL043 and GDL044 have significent difference on volume with the control, this 3 clones are the best. The clones of GDL042,GDL046 are next, their volume gain are over 25%,and have better performance in several test, this clones can be extend in afforestation for large scale in Guangdong.; |
