摘　　要：[目的]探讨小苗膜下移栽不同破膜时间对烤烟产量与产值的影响。[方法]以小苗膜下移栽后及时破膜、移栽后2 d破膜、移栽后4 d破膜3种不同破膜时间开展小区试验,并以常规栽培方式作对照。[结果]小苗膜下移栽后2 d破膜,烤烟产量产值最高,且超过了对照;移栽后及时破膜处理产量略低于对照,但产值略高于对照;移栽后4 d破膜处理的产量与产值均低于对照。[结论]移栽后2 d破膜为当地烤烟小苗膜下栽培的适宜破膜时间。Objective] The aim was to study the effects of different tearing film time on yield and quality of flue-cured tobacco transplanted by small seedlings under film. [Method] Four treatments （timely tearing film after transplanting, tearing film after two days of transplanting, tearing film after four days of transplanting and traditional transplanting method） were designed in this experiment. [Result] The results showed that the highest yield and quality was the treatment of tearing film after two days of transplanting, which was better than traditional transplanting method （CK）. The yield of timely tearing film after transplanting treatment was higher than CK treatment;however, its quality was lower than the latter. The yield and quality of transplanting were all lower than CK treatment. [Conclusion] The optimum tearing film time was two days after transplanting for flue-cured tobacco transplanted by small seedlings under film for this region.
