油茶是木本油料作物,寿命长,产量高,分布广,用途大,收益多,很有发展前途。它不但是一种很好的食油,而且是工业上重要的多种用油,可作机器滑润油,铁器防锈油;能制肥皂、人造奶油、蜡烛、凡士林、生发油、印泥油、燃油,以及医药等用;此外,茶枯还可以提气体点灯和炼汽油,也可作肥料和杀虫剂;果壳可以作活性炭、栲胶和制硷。我国是油茶的主要产地,而湖南产量约占全国总产量的一半,茶油既是对外贸易的主要物资,又是国内外市场上畅销的商品。因此,如何进一步改善现有油茶林的经营管理、提高单位面积产量以及扩大栽培面积等有关问题,都是林业科学研究中的主要任务。
Camellia oil-woody crops, long life, high yield, widely distributed, uses a large, more benefits, great prospects for development. It is not only a good cooking oil, but also a variety of important industrial oil, lubricants can be used for machinery, iron anti-rust oil; can make soap, margarine, candles, Vaseline, hair oil, mud oil, oil , As well as medicine, etc .; In addition, the tea can also be raised to light gas and gasoline, but also for fertilizers and pesticides; shell can be activated carbon, soy sauce and the system of alkali.
