油桐产业是贵州省罗甸县传统型林业产业,从20世纪70年代末开始发展、推广,80年代末大面积种植,到90年代油桐产业呈现出兴起和蓬勃发展态势。1997年亚洲金融危机爆发,油桐产业受到影响并逐年萎缩,油桐籽产量由1995年的4565吨下降到2007年的3000吨。这段时间,桐林无人问津,林业有害生物蔓延,危害油桐,油林老化较为严重。但在这之后,随着我国造船及电子等制造业的较快发展,加之人们环保意识增强,化学替代品又逐渐被桐油及其制品所取代,桐油价格逐渐升高。
The tung tree industry is a traditional type of forestry industry in Luodian County, Guizhou Province. Since the late 1970s, the tung tree industry has been developing, popularizing and large-scale cultivation in the late 1980s. By the 1990s, the tung tree industry has shown a trend of rising and flourishing. In 1997, when the Asian financial crisis broke out, the tung oil industry was affected and weakened year by year. The production of tung oil seeds declined from 4,565 tons in 1995 to 3,000 tons in 2007. During this time, no interest in Tong Lin, forestry pests spread, endangering tung tree, oil aging is more serious. However, with the rapid development of manufacturing industries such as shipbuilding and electronics in China and the enhancement of people’s awareness of environmental protection, the chemical substitutes were gradually replaced by tung oil and its products, and the price of tung oil gradually increased.
