摘　　要：完善烤烟新品种09011的配套栽培技术,为广元优质烟叶生产提供参考,采用单因素随机区组试验,研究3个不同施氮量(67.5kg/hm^2、82.5kg/hm^2及97.5kg/hm^2)对其农艺性状、经济性状及化学成分的影响。结果表明:烤烟新品种09011的株高、茎围、有效叶片数、最大叶长及最大叶宽等农艺性状及产量均随施氮量的增加呈增加趋势;产值、均价及上等烟比例等经济性状呈先升后降趋势。3个施氮量处理各部位烟叶的化学成分均较为协调。广元烟区烤烟新品种09011的适宜施氮量为82.5kg/hm^2。The effect of three different nitrogen application levels(67.5kg/hm2,82.5kg/hm2and97.5kg/hm2)on agronomic traits,economic traits and chemical components of new flue-cured tobacco line09011was studied by a single-factor random block design to perfect the complete set of cultivation technique and provide a reference for production of quality flue-cured tobacco in Guangyuan flue-cured tobacco growing region.Results:The height,stem girth,effective leaf number,maximum leaf length,maximum leaf width and yield of09011present the rising trend with increase of nitrogen application level but the output value,average price and first class tobacco proportion show the first rising and then declining trend with increase of nitrogen application level.The chemical components of different parts under three nitrogen application levels is harmonious.The optimum nitrogen application level of new flue-cured tobacco line09011is82.5kg/hm2in Guangyuan flue-cured growing region.
