元江县热区林地与膏桐资源现状调查及产业发展对策

Current status of forests and Jatropha curcas L. resources in tropical region of Yuanjiang County and its industrial development strategy

膏桐又名麻疯树、小桐籽、臭油桐,为大戟科(Euphorbiaceae)落叶灌木或小乔木,其种子含油量高,根系粗壮发达,是一种高含油量的生物能源油料树种,在土壤瘠薄、条件恶劣的干热河谷地区均能生长良好。通过对元江县热区范围内林地及膏桐资源进行全面调查,基本摸清了元江县林地资源现状及膏桐分布范围、生境条件等概况,并结合元江县林地资源分布特点、膏桐的生物学特性以及该县发展膏桐产业的优劣势条件,提出加大产业宣传力度、提高项目资金投入标准、抓好良种培育和示范林基地建设、增强全民生态保护意识等促进元江县膏桐产业发展的对策与建议。

Jatropha curcas L. is a deciduous shrub or small arbor and belongs to the family Euphorbiaceae. It has high oil content in seed and well developed root system which enables it to grow well in dry and hot valley with barren soil and appalling environmental conditions. In the present study, the forest lands and resources of Jatropha curcas L. in tropical regions of Yuanjiang County were investigated and the current status of forest land resources, their distribution and habitat conditions were worked out. According to the distribution of forest lands, the biological characteristics and the advantages and disadvantages of developing Jatropha curcas L., the industry in Yuanjiang County has been proposed. Awareness programs, fund acquisition for developmental projects, breeding improved varieties, establishment of demonstration forest base and improving the ecological protection consciousness among the people have also been discussed.
