摘　　要：为了探索提高烟叶镁含量的农艺措施,采用大田试验研究了叶面喷施镁肥对百色烤烟产量和品质的影响。结果表明,叶面喷施镁肥可改善烤烟的农艺性状,并能提高烟叶的经济效益,以T2（烤烟移栽后15,25 d喷施1%硫酸镁）、T3（烤烟移栽后15,25,35 d喷施0.5%硫酸镁）、T4处理（烤烟移栽后15,25,35 d喷施1%硫酸镁）的增效作用明显。总体上,叶面喷施镁肥处理烟叶镁含量增加,烟叶化学成分含量较为适宜、比例比较协调,烟叶评吸质量提高,以T4处理对提高各部位烟叶感官评吸质量的效果较为明显。因此,生产上百色烟区以在烤烟移栽后15,25,35 d喷施0.5%-1%浓度的硫酸镁较为适宜。In order to explore the agricultural measures for increasing the magnesium content of flue-cured tobacco, the effects of leaf-spraying magnesium fertilizer on yield and quality of flue-cured tobacco were studied by field experiments. The results showed that more leaf-spraying magnesium fertilizer could improve the agronomical characters of tobacco, and enhance the economic benefit significantly. Compared with CK, The economic characters of T2 treatment（leaf-spraying magnesium fertilizer at 1% and 15, 25 days after transplanting）, T3 treatment（leaf-spraying magnesium fertilizer at 0.5% and 15, 25, 35 days after transplanting）, T4 treatment（leaf-spraying magnesium fertilizer at 1% and 15, 25, 35 days after transplanting） were higher. On the whole, the applications of leafspraying magnesium fertilizer could increase the magnesium content in tobacco leaves, maintain better chemical component content and harmony, improve smoking quality, especially the application of leaf-spraying magnesium fertilizer at 1% and 15, 25, 35 days after transplanting（T4）. Therefore, the treatment of leaf-spraying magnesium fertilizer at 0.5% -1% and 15, 25, 35 days after transplanting was appropriate for flue-cured tobacco in Baise tobacco-planting area.
