不同钾肥对烤烟NC55产质量的影响

Effects of Different Potassium Fertilizer Application on Yield and Quality of Flue-cured Tobacco NC55

以烤烟品种NC55为试验对象,采用田间小区对比试验,研究2种钾肥替代硫酸钾作为基肥施用对烤烟产质量的影响。结果表明,采用枸溶性钾肥处理的烟叶,其田间生育状况、产质量均好于其他处理,烤后烟叶还原糖、钾含量有明显提高,烟叶品质最好。

Taking NC55 as material,the effect of two kinds of potassium fertilizer instead of potassium sulfate as base fertilizer on yield and quality of flue-cured tobacco was studied by field plot contrast test.The results showed that the growth status and yield quality of the tobacco treated with citrate soluble potassium fertilizer were better than other treatments,and the reducing sugar and potassium content of the cured tobacco significantly increased,and the quality of the tobacco was the best.
