主要生物柴油树种整形修剪技术研究进展
Research Status of Several Major Bio-diesel Trees on Pruning Techniques

以文冠果（Xanthoceras sorbifolia）、黄连木（Pistacia chinensis）、小桐子（Jatropha curcas）、光皮树（Cornus wilsoniana）等4个我国主要生物柴油树种为对象，总结了其生物学特性及整形修剪技术。在生物学特性方面，主要总结和对比了4个树种树体、花、果、以及物候期。在整形修剪技术方面，主要通过对4个树种骨干枝开张角度、骨干目和修枝数剪方法等方面的分析和对比，初步总结出适应于这些生物柴油树种整形修剪的技术，为生物柴油原料林产量提高奠定了理论和实践基础。
Biological characteristics and pruning techniques of four representative tree species for making bio-diesel in China were reviewed, such as Xanthoceras sorbifolia，Pistacia chinensis, Jatropha curcas, and Cornus wilsoniana. Biological characteristics included tree shapes, flowers, fruit, and the phenology, while the pruning techniques were the opening angle of main branches through the backbone, the number of branches through the backbone and pruning methods. Prunning methods that are suitable for these species were summed up to promote the yields of the raw materials for bio-diesel production
