Effects of applying potassium-organic,potassium and magnesium-organic fertilizer on potassium content,yeild and quality in Flue-cured tobacco

Field experiment was conducted to study the effects of the application of potassium-organic feitilizer,potassium and magnesium-organic fertilizer on flue-cured tobacco growth,potassium content,yeild and quality of leaves.The result showed that plant height,max leaf area,stem diameter,pitch,leaf number and dry matter accumulation on the application of potassium-organic fertilizer were increased.The potassium content of upper,middle and lower leaves of the potassium-organic fertilizer,potassium and megnesium-organic treatments were higher than the pure fertilizer treatment(CK),in which the potassium content of lower leaves of potassium-organic treatment and of middle,lower leaves of potassium and megnesium-organic treatment were extremely significantly higher than pure fertilizer treatment(CK) treatment;potassium-organic treatment increased the average price and output value significantly;the potassium and megnesium-organic treatment increased the the yeild,averager price and output value significantly,and improved the coordination between main chemical components,also enhanced the proportion of superior tobacco.
