广西6种木本油料植物的资源概况及其在岩溶山区的开发前景

茶条木、狗骨木、蒜头果、石栗、东京桐和蝴蝶果等6个树种是高含油量和多用途的木本油料植物，也是具有一定发展前途的生物质能源树种。野外调查表明，茶条木、狗骨木、石栗和蝴蝶果等分布或栽培范围较广，生境类型比较复杂，现存资源量丰富或较多；蒜头果和东京桐的分布范围较窄，现存资源量较少。在育苗造林试验中，6个树种种子的场圃发芽率较高，病虫害少，苗木生长比较迅速，绝大部分可在1-2年内出圃造林；茶条木、狗骨木、石栗、东京桐和蝴蝶果等5个树种的植苗造林成活率较高，蒜头果的直播造林成活率较低，其中茶条木和狗骨木的适应性良好，生长速度较快，东京桐和蒜头果能适应局部小环境但生长较慢，而石栗和蝴蝶果的适应性较差且生长缓慢。通过对比分析各树种野外调查与试验结果，认为茶条木和狗骨木是岩溶山区发展潜力良好和值得重点开发利用的木本油料植物，蝴蝶果和石栗次之，蒜头果和东京桐则较差。

Resources survey of six woody oil plants in Guangxi and their development prospect in Karst mountain region

Delavaya toxocarpa,Cornus wilsoniana,Malania oleifera,Aleurites moluccana,Deutzianthus tonkiensis and Cleidiocarpon cavaleriei are six woody oil plants with high oil content and multipurpose,and they are also tree species as bio-energy with a good development future.Field investigation showed that the Delavaya toxocarpa,Cornus wilsoniana,Aleurites moluccana and Cleidiocarpon cavaleriei have a wide range of distribution and cultivation with more complicated ecological habitat types and are abundant in quanti...
