摘要
试验结果表明，不同植物生长调节剂在烤烟生长过程中能提高烤烟生理活性，增加烤烟叶绿素含量，光合速率加快，对累积烟叶内含物质有利，且能改善烟叶质量增加烟叶的产量。其中以茶叶香醇素效果较好。
The results of experiment showed that the physiological activity of flue-cured tobacco, leaf chlorophyll content and photosynthetic rate could be increased by applying different plant growth regulators The leaf quality and yield could be improved.
