摘要
本文首先扼要叙述了桉树扦插的一般技术环节,进而系统归纳并分析了目前桉树扦插技术中的问题,指出改进根系质量与提高生根率具有同等重要的意义,并提出了研究克服无性系内变异的概念。文章还简要介绍了与上述问题研究相关的三项试验及其初步结果。这三项试验是:桉树生根性能杂交继承性试验;系内生根性能变异试验;光对桉树扦插的影响试验。这三项试验进一步具体说明了当前桉树扦插中值得注意的技术问题。文章指出,解决上述扦插技术问题,有助于开发我国南方桉树经济潜力。
The common technical links on the cutting of Eucalyptus are reviewed in the paper,and then the existing echnical problemsof the cutting of Eucalyptus are induced and analysed.Both thepromotion of the root′s quality nd he increase of the rate oftaking root are regarded to have the same significance.The conceptof research on the vercoming the interclonal varibility is also Posed.In the paper,the three trials(crossing and inheriting perfromancetrial of taking root of Eucalyptus;performance trial of variahle reasonsof taking root within the lone;impacet trial of light on tits catting ofEucalyptus) and their tentative results related to the above-mentionedresearch problems are presented in brief,which further illustratedthe attentive technical problems in the urrent cutting of Eucalyptusspecifically.In addition,the paper also present that solving the above-mentionedtechnical roblems will be helpful to exploit the economic potentialityof Eucalyptus in southern China.
