土壤施钾对烤烟品质的影响研究

Effects of application of fertilizer K on the quality of flue-cured tobacco in Sichuan Province

试验研究土壤施K对四川烤烟品质的影响结果表明,施K可提高烟叶中K和还原糖含量,降低Ca、Mg、烟碱和蛋白质含量;不同植烟土壤施K影响效应各异,红壤施K对烟叶品质影响较小,而紫色土和黄壤施K则影响显著。

The effects of application of fertilizer K on the quality of flue-cured tobacco in Sichuan Province were studied. The results show that applying fertilizer K can raise the contents of potassium and reduced sugar,decrease the contents of calcium, magnesium, nicotine and protein in flue-cured tobacco. It is concluded that the effects of the application of fertilizer K on the quality of flue-cured tobacco in three soils are different evidently,the effect is little in red soil and significant in calcareous purple soil and yellow soil.
