广西来宾地区引种大花序桉生长情况分析

Analysis on Growth of Introduced Eucalyptus cloeziana in Laibin, Guangxi

摘要: 在广西来宾地区引种1212号、1225号2个种源大花序桉，营建大花序桉纯林及大花序桉×尾巨桉复合经营林分。结果表明：利用1212号种源营建的复合经营林分中2.5年生大花序桉生长显著高于混合种源，且在纯林中1212号种源表现同样优于1225号种源。1212号种源更适应来宾地区气候和土壤条件，具有一定的推广价值。

Abstract: In this study, two excellent provenance Eucalyptus cloeziana No.1212 and No.1225 were introduced in Laibin, Guangxi, and the pure Eucalyptus cloeziana forest and the mixed management forest of Eucalyptus cloeziana × Eucalyptus urophylla were built. The results showed that the growth of 2.5-year-old Eucalyptus cloeziana in the compound management forest constructed by provenance No. 1212 was significantly higher than that of the mixed provenance, and provenance No. 1212 was also better than provenance No. 1225 in pure forest. Provenance No. 1212 was more suitable for the climate and soil conditions in Laibin area, and had certain popularization value.
