摘　　要：剪叶是烤烟漂浮育苗过程中广泛采用的一种炼苗措施。综述了烤烟漂浮育苗中不同剪叶次数和不同剪叶程度对烟苗的植物学性状及生物量积累、根系活力及叶片生理特性、烟苗抗病性及病毒传播、烤烟大田生长农艺性状、现蕾期及最终产量产值的影响,并从剪叶对植物光合作用及同化产物分配两方面探讨了剪叶刺激烟苗产生超越补偿反应的机制,提出了烤烟漂浮育苗剪叶技术需要进一步研究的问题,为剪叶的壮苗理论研究提供参考。Clipping is widely used in management of flue-cured tobacco seeding in float system. In this paper, we summarized different clipping times and different clipping intensity of float-seeding effect on botanical character and biomass accumulation, root activity and leaf physiology characteristic, disease resistance and virus spread of flue-cured tobacco seeding, also, we summarized research advances on the effects of clipping on agronomic traits, flower bud stage of flue-cured tobacco in field, and the finally yield and value. Besides, we made discussion about overcompensation responses mechanisms of clipping from photosynthesis and assimilate distribution, and offered reference for further study on the clipping of flue-cured tobacco seeding in float system.
