| 摘要: |
| 为了解广林-9号、DH32-29、DH201-2、U6共4个桉树无性系在广东省梅州地区的引种栽培效果，采用抽样调查法和市场调查法，对其生长量、耐寒性、市场经济效益等方面进行研究。结果表明：广林-9号、DH32-29具有生长快、耐寒性强、经济价值高等优点，适宜作为梅州市用材林树种；DH201-2、U6生长较慢，木材利用率较低，应减少种植。为减小冻害风险，梅州地区桉树造林海拔应低于500 m。 |

| Abstract: |
| In order to explore the introduction and cultivation of four Eucalyptus clones, including Guanglin-9, DH32-29, DH201-2 and U6 in Meizhou, this paper adopted the sampling survey method and the market research method to analyze the traits of growth, cold-resistant ability and economic value. The results showed that with fast growth, strong cold resistant ability and the economic value, Guanglin-9, DH32-29 were suitable as a timber tree species in Meizhou. The planting of DH201-2 and U6 should be reduced owing to the slow growth and low wood utilization. To reduce the risk of cold damage, Eucalyptus plantation should be planted at less than 500 m above sea level in Meizhou.\ |
