时空分布对油樟精油含量的影响研究

The influence of Temporal and Spatial Distribution on Essential Oil Content in Cinnamomum longepaniculatum

摘要: 本文通过调查时空分布对宜宾油樟精油含量的影响发现:油樟中精油含量在4月份最高,6月份至11月份维持在一个稳定水平;在含油率较高的4月份,11 a~20 a树龄的油樟含油率明显较高,阳坡高于阴坡;海拔高度对油樟精油含量无明显影响。

Abstract: In this paper,researches were conducted on the influence of temporal and spatial distribution on essential oil content from Cinnamomum longepaniculatum. The result found that the maximum essential oil content in Cinnamomum longepaniculatum was in April,then kept at stable level from June to November. In April,C. longepaniculatum at the age of 11 to 20 had significantly higher oil rate. The oil rate of C. longepaniculatum on positive edge was higher than that on the negative edge. The altitude had no obvious effect on the content of essential oil in Cinnamomum longepaniculatum.
