摘　　要：以云烟87品种为材料,研究了不同揭膜培土方式对烤烟产质量的影响。结果表明:相同生态条件下,不同揭膜培土处理的烤烟产值量存在差异,打顶时揭膜培土加追肥处理的产值量最高;烤烟根系的发育与揭膜的时间密切相关,迟揭膜处理的根鲜重大于早揭膜和不揭膜处理,追肥处理的根鲜重大于不追肥处理的根鲜重,晚揭膜、施肥再加培土对烤烟根系的生长发育极为有利;前期根系发育状况良好是促进烟株茎围增大和上部叶片的开片的直接原因,而对烟叶内在化学成分的影响较小。The effects of different methods of removing film and hilling on the yield and quality of flue-cured tobacco（YUN87） were studied.The results showed that under the same ecological conditions,the yield of tobacco treated by different methods of removing film and hilling was different.When removing film,hilling and applying fertilizer at topping period,the yield of tobacco was the highest.The development of tobacco root system closely relate to the time of removing film,the root fresh weigh of removing membrane in late time is heavier than that of removing film in early time or non-removing film;the root fresh weigh of applying fertilizer is heavier than that of non-applying fertilizer.Therefore,the treatment that removing film late,applying fertilizer and hilling is propitious to the growth of root system.Growth of root system in early time in a good condition is the direct cause to promote the growth of tobacco plant stem and upper leaves,but it has less affection on the intrinsic chemical composition of tobacco leaves.
