采集了广西河池各烟区195个土种样品，并对其中量和微量营养元素进行了检测分析。结果表明：全市植烟土壤交换性钙、有效硫和有效锌含量整体较为适宜，交换性镁含量普遍缺乏，有效硼含量普遍严重缺乏，有效铁含量普遍偏高。因此，生产上应结合烟叶内中量和微量营养元素丰缺状况，合理补充施用部分中量和微量元素肥料，尤其是加大镁肥和硼肥的推广力度。%In this study , 195 soil samples were collected form different tobacco -growing regions of Hechi in Guangxi , and the contents of medium elements and microelements in them were tested and analyzed .The results indicated that:in the soil of Hechi tobacco-growing region , the contents of exchangeable Ca , available S and effective Zn were generally moderate , the content of ex-changeable Mg was generally deficient , the content of available B was severely insufficient , and that of available Fe was prevalently high.Therefore, some medium-element and microelement fertilizers (especially Mg fertilizer and B fertilizer ) should be properly supplemented and applied in the production of flue -cured tobacco in this region .
