摘要
Abstract
Pot experiment with sand was carried out with K 326 as material to study the effect of nitrogen deficiency and po-tassium deficiency after topping on the chlorophyll content , nitrate reductase activity , root activity and nicotine content of flue-cured tobacco.The results showed that lacking of nitrogen and potassium had significant influence on physiological properties and nicotine content.As for chlorophyll content , nitrate reductase and root activity , there existed trend of CK >potassium deficiency treatment >nitrogen deficiency treatment.But for nicotine content there showed trend of potassium deficiency treatment >CK>nitrogen deficiency treatment , and there were significant difference among treatments.Over-all, nitrogen and potassium stress were not advantageous to growth and development of flue -cured tobacco.关键词
