广西耐寒桉树改良和栽培技术研究项目实施 3年来 ,着重开展了下面几个方面的工作 :(1)对 1991年建立的邓恩桉 (E dunnii)种源 /家系试验林进行了观测研究 ,包括种源及家系的生长表现 ,开花物侯与种子生产能力的研究 ,促进邓恩桉开花结实试验、邓恩木材基本密度的分析测定 ;(2 )从澳大利亚引进多枝桉、邓恩桉等 10多个耐寒桉树种 /种源 ,建立了新的耐寒桉品种试验林 ;(3)扩大邓恩桉栽培范围 ,在广西、江西以及湖南建立起邓恩桉种源试验与示范林 ;(4)开展了邓恩桉、柳窿桉 (E saligna×E exserta)组培无性繁殖研究 ,建立了 8个无性系无菌体系 ;(5 )对栽培耐寒桉树的柳州、桂林两地试验点的立地进行了评估。此外 ,还指出了项目存在问题及下一步的工作展望。
In the past three years since the implementation of the research project on improvement and cultivation of cold-tolerant eucalyptus in Guangxi, the following work has been focused on the following aspects: (1) Observational studies of E dunnii provenance / pedigree experimental forests established in 1991 were conducted, including provenance (2) From Australia introduced more than 10 eucalyptus, Dunn Eucalyptus and other more than 10 cold-resistant eucalyptus species / seedlings, (3) expanding the range of cultivation of Dunn Eucalyptus, establishing the provenance and demonstration forest of Dunn Eucalyptus in Guangxi, Jiangxi and Hunan; (4) developing the Edenigna, Eucalyptus, × E exserta), and 8 clones were established. (5) The site of the test sites of Liuzhou and Guilin, which were cultivated with cold hardy eucalyptus, was evaluated. In addition, the problems of the project and the future work outlook are pointed out.
