摘要
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.
