摘要:

调查分析5种不同前茬立地类型的桉树人工林生长及其土壤肥力情况，结果表明：相思前茬立地类型的4.5 a生桉树人工林具有最高的保存率、平均胸径、平均树高和平均每公顷材积，分别为92.4%、13.5 cm、18.4 m、153.6 m3，相思前茬立地可能是较理想的桉树人工林造林立地类型。进行桉树人工林多代经营时，相思、桉树前茬都是可以选择的立地类型，但一定要加强造林后的抚育管理，才能获得较高的材积。

Abstract:

This paper studied on the growth performance of Eucalyptus plantations at different previous plantations site types, and analyzed soil fertilities after planting Eucalyptus plantation. The results indicated that the 4.5yearold Eucalyptus plantation had the highest survival rate (92.4%), diameter at breast height (13.5 cm)，height (18.4 m) and per hectares wood volume (153.6 m3), when planting at the site type of Acacia as the previous plantation. Both the site types of Acacia and Eucalyptus as previous plantation were appropriate for several generation management of Eucalyptus plantation, and nurture management after planting were necessary for higher volume.
