在2年生的桉树引种试验林内,对蓝桉和新引种的5种其他桉树的地上部分生物量进行了测定。研究发现,当轮伐期为2年时,不同桉树的芳香油和薪材收获量差异显著,而同一树种的芳香油和薪材产量在不同造林密度之间无显著差异。史密斯桉和贝克桉的芳香油和桉树脑含量均高于蓝桉,是生产桉树芳香油和薪材的优良树种,在我国亚热带地区有进一步试验和推广的价值。
In the biennial Eucalyptus Introduction Trial Plantation, the above-ground biomass of Eucalyptus globulus and the five newly introduced Eucalyptus species was determined. The study found that when the rotation period was 2 years, there was significant difference in the yield of aromatic oil and fuelwood between different eucalypts, while there was no significant difference in the yield of aromatic oil and firewood between different afforestation density in the same species. The contents of aroma oil and eucalyptus in both Eucalyptus and baker’s eucalyptus were higher than that of Eucalyptus globulus, which is an excellent tree species for producing eucalyptus aromatic oil and firewood. It has the value of further testing and popularization in the subtropical regions of China.
