油樟 [Cinnamomum Longepaiculatum(Gamble)N.Chao]是优良用材和重要的芳香油料树种,具分布广、生长快、萌芽力强、含油率高、油质好等特点。从1958年开发利用到1981年,仅宜宾县就为国家提供商品樟油1095.42万斤。1980年后,全县每年樟油产量均在90万斤以上。为解决目前生产中存在每年采叶蒸馏时间长(4月初至8月底),出油率不高等问题,我们进行了油樟不同采叶期的出油率试验,以寻求最佳采叶期。一、材料和方法 1.供试材料在宜宾县油樟分布中心观音区隆兴公社大月亮山上无食叶害虫的油樟纯林中,采取树干中下部的当年生枝叶(包括春梢和夏梢)。
Oil camphor [Cinnamomum Longepaiculatum (Gamble) N.Chao] is an excellent timber and important fragrant oil species, with wide distribution, fast growth, strong sprout, high oil content, good oil quality and so on. From 1958 to 1981, only Yibin County provided 10,954,200 kilos of commodity camphor oil to the country. After 1980, the annual output of camphor oil in the county was above 900,000 kg. In order to solve the problem that there is a long time of leaf decay distillation (early April to the end of August) and the oil yield is not high in the current production, we conducted the oil yield test of oil camphora at different harvest times in order to find the best harvest time. I. Materials and methods 1. The test materials In the Yibin County Oil Camphor Distribution Center Guanyin District Longxing Commune large moon Hill without leaf pests oil camphor pure forest, to take the middle of the lower branches of current year branches (including spring shoots and summer Shoot).
