Abstract
Field experiment was conducted to study the effect of different supplying styles of potassium fertilizer on potassium content in flue cured tobacco leaves and the methods to increase the content. The result of the study demonstrates that adding potassium fertilizer may significantly increase its yield and potassium content of tobacco leaves especially of middle and upper leaves. Potassium in leaves can also be significantly increased through spray “You Feng 98 2” foliage fertilizer. In calcareous soil, drought is the key factor influencing the potassium content of tobacco leaves. Powder fertilizer is slight better than granulated fertilizer in increasing potassium content of the leaves in special arid condition. Soil application accompanying with foliage fertilization was an effective measure to increase potassium content of flue cured tobacco in calcareous soil.
