Abstract
[Objective] The objective of the research was to explore the adjusting effects of different nutritive regulating measures before and after the topping time on potassium and nicotine in tobacco leaves.[Method] The adjusting effects of different nutritive regulating measures on potassium and nicotine in tobacco leaves were studied in field experiment.[Result] With the rise of fertilization level,potassium content in tobacco leaves showed a decreasing trend in rosette stage approximately and showed an increasing trend in vigorous growing stage,but there was a difference on the change tendency of nicotine content in tobacco leaves.Contents of potassium and nicotine in tobacco leaves in the treatment of higher fertilization level in round top stage showed a decline trend.Combined with smearing once auxin in topping stage,keeping its top unremoved and applying potassium sulfate after transplanting could increase potassium content in tobacco leaves and decrease nicotine content of tobacco leaves,and the latter had more significant effects on increasing potassium and reducing nicotine.[Conclusion] The research provided scientific basis for formulating reasonable regulating measures in tobacco production,and its extension and application.
