Abstract
[Objective] To research the effects of potassium fertilizer amount on the growth,yield and quality of flue-cured tobacco K326.[Method] Field plot experiment was adopted to research the effects of potassium fertilizer amount on the agronomic characters,economic character and inherent chemical composition.[Result] With the increase of potassium application,plant height and stem diameter of tobacco increased,and the yield and output value enhanced in different degrees.With the increase of potassium content in tobacco leaves,the contents of water-soluble sugar,reducing sugar,total nitrogen and other inherent chemical compositions decreased or incrased in different degrees,the chemical composition tend to be coordinated,and the inherent quality improved.Under the level of 105 kg/hm2 nitrogen,application of 367.5 kg/hm2 potassium fertilizer showed the best effects.[Conclusion] This research provides theoretical foundation for enhancing the potassium content of tobacco leaves,reducing the oil tar cotnent of tobacco leaves,enhancing the safety of tobacco leaves and its products.关键词
