摘要
对昆明市海口林场2012年栽植的5种桉树早期生长性状进行了观测研究。结果发现,5种桉树中,造林成活率较高的有本沁桉、邓恩桉及多利桉,树高和地径表现最优的是多利桉。不同种桉树中苗圃地生长表现最优的,上山栽植以后生长表现不一定最优,这与不同生长发育阶段、不同环境条件有着密切关系。
A research on early growth traits of 5 kinds of eucalyptus was carried out at Haikou forest farm of Kunming in 2012. The results showed that among 5 kinds of eucalyptus, E. benthamii, E. dunnii and E. dorrigoensis have higher forestation survival rate, and the E. dorrigoensis has the best perform- ance at ground diameter and tree height. Different kinds of eucalyptus might performed optimal growth traits at nursery, but not necessarily performed optimal growth traits at uphill after planting, for the growth situation affected closely by different growth stages and at different environmental conditions.
