摘　　要：为了探索水涝胁迫对烤烟的影响,研究了利川开展烤烟不同生育期不同水涝时间对烤烟某些理化特性及产质量影响。结果表明,在烟草团棵期、旺长期、成熟期,随着淹水时间的增加,根系活力受损程度逐步加深,导致烟叶的光合速率降低,叶绿素合成逐步减少,SPAD值降低。同时,随着淹水时间的增加,烤烟产量、产值、均价、上等烟比例和烟叶的感官质量均呈下降趋势,但烟叶的化学成分受影响较小。因此,南方烟区在烟叶的种植布局过程中,要选择较高的地势,完善排水设施,避免涝灾损失。In order to research the effects of waterlogging stress on flue-cured tobacco,experiments of different waterlogging time at different growing stages of flue-cured tobacco on physicochemical properties,yield and quality were carried out in Lichuan.The results showed that during the rosette,vigorous growth and mature stage,the damage degree of root activity was gradually deepened with the increase of waterlogging time,leading to the decrease of photosynthetic rate,chlorophyll synthesis and SPAD value of tobacco leaves.Moreover,with the increase of waterlogging time,the flue-cured tobacco yield,production value,average price,the proportion of first-class tobacco leaves and sensory quality of tobacco leaf showed a downward trend,but the chemical compositions in tobacco leaf was less affected.Therefore,in southern tobacco areas,choosing the higher terrain and perfecting drainage facilities in planting zoning adjustment could avoid the loss of waterlogging.
