广西不同产地岗松的生物量和得油率研究

摘要

[目的]筛选广西生物量高、含油率高的岗松品种.[方法]2016年10月,通过对广西11个产地岗松的生物量和得油率进行测定.[结果]钦州地区的岗松绝干得油率最高,为1.49％,生物量较高的岗松也是在钦州等沿海地区.岗松优良单株的选择不仅取决于生物量和得油率,还要考虑其挥发油的主要化学成分含量.[结论]该研究可为岗松的选优及推广种植提供借鉴.%[Objective]To screen high biomass, high oil yield of varieties of Baeckea frutescens. [Method] The biomass an d oil yield of different origin of Baeckea frutescens in Guangxi were detected in October 2016. [Result]The results showed that the Qinzhou area had the highest rate of dry oil, reaching 1. 49％, and the higher biomass, which was also in coastal areas such as Qinzhou. The selection of superior individuals should not only consider the biomass and oil yield, but also consider the main chemical components in the volatile oil. [Conclusion]The study can pro-vide reference for the selection and planting of Baeckea frutescens.
