The results showed that plant height increasing speed was significantly slow at the former and middle stage when K level was above 180 kg/hm2.On the contrary,the height of case-hardened plant improved markedly.When the K level was above 135 kg/hm2,the stem girth and maximal leaf area differed significantly as compared with CK,so did LAI.Yield and product value per unit area took the first place when 180 kg/hm2 potassium was used.Average price and proportion of middle and first grade tobacco leaf of 225 kg/hm2 potassium treatment were the highest as compared with other treatments and CK.Four economic characters of the two treatments differed at obvious significant level as companied with CK.The total sugar and K2O were increased,nicotine, total N,protein and Cl- were decreased with increased K levels.The potassium lacked symptom was alleviated with increased K levels,no symptoms was observed when 180 kg/hm2 potassium was used,the degree of weather infected fleck was decreased when the K levels was increased.
