摘　　要：通过田间试验,考察了施用有机酸-钾肥(F-k)、有机酸-钾镁肥(F-kMg)对烤烟生长、烟叶含钾量及产质量的影响。结果表明,施用有机酸-钾肥增加烤烟株高、最大叶面积、茎径、节距和叶片数,促进烤烟干物质的积累;F-k、F-kMg处理烤烟的上、中、下部叶的钾含量均高于纯化肥处理,其中F-k处理烤烟下部叶的含钾量、F-kMg处理烤烟的中、下部叶钾含量极显著高于纯化肥处理;施用有机酸-钾肥的烤烟烟叶的均价、产值均显著高于纯化肥处理;施用有机酸-钾镁肥可以显著提高烤烟烟叶的产量、均价及产值,同时可以改善烟叶主要化学成分的协调性及提高中上等烟比例。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.
