Abstract

By using the cultivation method of transplanting the seedlings in the nutritional bowl to the field,this paper studied the effect of different potassium fertilizer application levels on the agronomic traits,yield and quality of flue-cured tobacco under the condition of applying the same amount of nitrogen and phosphorus fertilizer.The results showed that the best ratio of N,P and K was 1∶1∶2,because the flue-cured tobacco in this treatment had good agronomic traits,the highest single-leaf weight and dry matter weight,high yield,and good quality.
