史密斯桉种源试验林的生物量及桉油测定分析

以发展云南桉树材用林和油料林为目的，于1995年从澳大利亚引进史密斯桉主要分布区的7个种源，以蓝桉和直干桉作对照，在云南省的5个试验点进行多点引种和种源适应性试验。为确定云南适宜发展的史密斯桉种源，测定分析了不同种源的生物量、出油率及化学成分。结果表明，史密桉在出油率、平均单株产油量、1，8-桉叶素含量等方面都优于直干桉和蓝桉，引种的7个种源中，18676，15064，18681，16916等4个种源较适合在云南局长材用或用林、油料兼用林。

A Test and Analysis of Biomass and Eucalyptus Oil In Eucalyptus smithii Provenance Trial

For the purpose of developing timber and oil forests of Eucalyptus in Yunnan Province from Australia in 1995,seven Eucalyptus smithii provenances were introduced to 5 experiment sites in Yunnan for an introduction and provenance test by using E.globulus and E.maideni as control.To define suitable E.smithii provenances in Yunnan,biomass,oil ratio and chemical composition of different provenances were tested and analyzed.In April,1997 and March,1998, E.smithii provenances were tested in Baoshan city and Lufeng respectively.The results indicated that E.smithii was better than E.globulus and E.maideni in oil ratio,average individual oil production,1,8-cineol content,etc. Among the 7 provenances,4 with the codes of 18676,15064,18681 and 16916 were more suitable to develop timber Forests or both timber and oil forests in Yunnan.
