引进史密斯桉、蓝桉等5个桉树品种152个家系在昆明市海口林场苗圃进行育苗,对苗期苗高和地径生长情况进行观测和分析。结果表明,5个桉树品种苗高和地径平均值之间存在较大变异,品种间平均苗高生长量差异达到极显著水平,品种间平均地径生长量差异不明显。经多重比较后认为,史密斯桉在海口林场苗期生长表现较好。
A total of 152 eucalyptus species including 5 eucalyptus species such as Eucalyptus globulus and Eucalyptus globulus were introduced into nursery in Haikou forest farm in Kunming. The seedling height and diameter growth were observed and analyzed. The results showed that there was a great variation between the height of seedlings and the mean value of ground diameter of five eucalyptus varieties, and the difference of average seedling height growth among the cultivars reached extremely significant level. After multiple comparisons, it is considered that the growth of Eucalyptus mirifica in seedling stage of Haikou forest farm is better.
