摘要: 以云烟87为研究对象,分析干旱胁迫下不同木醋液种类对烤烟叶绿素含量、气体交换参数、叶绿素荧光参数、根系结构、根系活力指标的影响。结果表明,与对照相比,正常生长和干旱胁迫条件下施用木醋液均能提高烟株光合效率、促进烟株根系生长;干旱胁迫处理使烤烟光合效率及根系活力降低,施用木醋液在一定程度上可以缓解干旱对烟株光合效率及根系生长的不利影响,不同木醋液种类影响效果不同,以桃壳木醋液效果较好。

Abstract: Yunyan 87 was used as research object to analyze the effects of different wood vinegar species on chlorophyll content, gas exchange parameters, chlorophyll fluorescence parameters, root structure and root activity of flue-cured tobacco under drought stress. The results showed that the application of wood vinegar under normal growth and drought stress conditions could improve photosynthetic efficiency and promote root growth of tobacco plants compared with the control. The photosynthetic efficiency and root activity of flue-cured tobacco decreased under drought stress. The application of wood vinegar could alleviate the adverse effects of drought on the photosynthetic efficiency and root growth of flue-cured tobacco. Different wood vinegar types had different effects, and peach-shell vinegar had better effect.

Key words: drought stress, flue-cured tobacco, wood vinegar, photosynthesis, root system
