云南烟叶和烟梗钾氯含量差异分析

Analysis on the Difference of Potassium and Chlorine Contents of Tobacco Leaves and Tobacco Stems in Yunnan

对云南曲靖、昆明、红河3个典型烟区主栽烤烟品种K326、红花大金元、云烟87的B2F、C3F和X2F等级烟叶及烟梗的钾氯含量进行差异分析,结果表明,云南烟叶、烟梗钾含量均随着生部位的升高呈线性递减趋势,氯含量呈线性递增趋势;烤烟K326品种具有较好的钾素富集能力,红花大金元具有较好的氯富集能力;云南典型烟区烟叶和烟梗钾、氯含量存在明显的区域异质性。总体而言,云南烤烟中上部位烟叶钾含量偏低、氯含量偏高,烟梗可以用于开发高钾型炭基肥。

The potassium and chlorine contents of B2F,C3F and X2F tobacco leaves and stems of flue-cured tobacco varieties K326,Honghua Dajinyuan and Yunyan 87 planted in three typical tobacco regions in Yunnan Province were analyzed,the results showed that the potassium contents of Yunnan tobacco leaves and tobacco stems decreased linearly with the increase of growing parts,and the chlorine content increased linearly.The flue-cured tobacco variety K326 had better potassium enrichment ability,and Hongda had better chlorine enrichment ability.There was obvious regional heterogeneity in potassium and chlorine contents of tobacco leaves and stems in typical tobacco growing areas in Yunnan.In general,the potassium content of middle and upper parts of Yunnan flue-cured tobacco leaves is low and the chlorine content is high.The tobacco stems can be used to develop high potassium carbon based fertilizer.
