Abstract：The field experiment was carried out to study the effects of different nitrogen rates on the flue -cured tobacco growth and development,economic characters,smoking quality and nicotine content with the cultivar K326 as material.The results showed that increasing the nitrogen application rate in a certain range could significantly promote the growth and development of tobacco,improve the smolking quality and in-crease the nicotine content.When the nitrogen rate was 90 kg/hm2 ,the agronomic traits,dry matter accumula-tion and economic characters performed better,the smoking quality was the best,and the nicotine content was moderate.It suggested that under the conditions of this test,90 kg/hm2 of nitrogen rate could meet the growth and development need of tobacco,which layed foundation for upgrading the quality of flue -cured tobacco.
