| 摘 要： | 为改善烤烟上部叶片的工业可用性,研究了不同采收方式对云烟87上部叶片烘烤前生物性状和烤后物理特性的影响。结果表明：集中采收比常规采收的烟叶叶片略薄,单叶重减轻,比叶重、叶片密度下降,组织结构疏松,叶片间差异缩小,可提高上部烟叶的可用性,但是集中采收可能会因为单叶重减轻而导致产量有所下降。 |

| Abstract: | Effects of different harvesting methods on biological characteristics before curing and physical properties after curing of upper leaves of Yunyan 87 were studied to improve the industry usability of upper leaves.The results showed that compared to common harvesting method,harvesting upper leaves in one-time resulted in slightly thinner leaves,lighter single-leaf-weight,decreasing specific leaf weight and leaf density,softer organizational structure and less difference among six upper leaves.Harvesting in one-time could improve the usability of upper leaves,while the yield could be decreased deduced by decrease of single-leaf-weight. |
