| 摘要: |
| 对11个桉树6 a生无性系在广东省江门市低丘台地进行了区域测定，结果表明：树高生长表现最好的前3名分别是广9、DH32 29和196无性系，胸径生长表现最好的前3名分别是196、DH32 29和广9无性系，单位面积蓄积最高的前3名分别是196、广9和DH32 29无性系。综合分析结果，196无性系在6 a生时，树高为19.33 m，胸径为13.55 cm，单位面积蓄积为173.75 m3/hm2，单位面积木材价值为93 831.70元/hm2，是非常值得推广种植的无性系。 |

| Abstract: |
| The field trails and economic benefits of eleven eucalyptus clones (6 years old) were conducted on a low hill in Jiangmen city of Guangdong province. The results showed that：Guang 9, DH32 29 and 196 ranked in the top 3 of the plant height. 196, DH32 29 and Guang 9 ranked in the top 3 of the diameter at breast height (DBH). 196, Guang 9 and DH32 29 ranked in the top 3 of the volume per hectare which was determined by plant height, DBH and conservation rate. According to the results, 6 year old of clone 196, the height, the diameter at breast height and the volume of per hm2 were 19.33 m, 13.55 cm and 173.75 m3/hm2, respectively; and its economic benefit was 93 831.7 RMB/hm2. 196 was the best clone which was worth promoting in Jiangmen city of Guangdong province. |
