| 摘 要： | 为明确攀枝花烟区镁肥施用标准，通过田间试验，研究了攀枝花烟区镁肥的施用对烟叶产量、质量的影响。结果表明：（1）镁肥的施用对烟叶团棵期的田间长势无影响，但对烟叶打顶后的田间长势影响明显，且随着施用量的增加，田间长势增加。（2）镁肥施用量在75 kg/hm2范围内时，随着施用量的增加，烟叶产量、质量、中上等烟比例呈增加趋势，施用量超过75 kg/hm2时，烟叶产量、质量、中上等烟比例呈减少趋势。（3）镁肥的施用对优化烟叶内在质量有明显效果。

| Abstract: | To establish the application standard of magnesium fertilizer in Panzhihua tobacco planting areas, a field experiment was conducted, and the effect of magnesium fertilizer on tobacco leave yield and quality was studied. The results showed that: (1) the application of magnesium fertilizer had no effect on tobacco at the resettle stage, on the contrary, significant effect was observed at the topping stage, and with the increasing of the magnesium fertilizer amount, the tobacco growth performance was also improved; (2) when the amount of magnesium fertilizer was within 75 kg/hm2, the total tobacco leave yield, quality, and the ratio of mid-high grade leave all increased with the increasing application of magnesium fertilizer, while when the amount of magnesium fertilizer was over 75 kg/hm2, all the above related indexes decreased; (3) the results suggested that the application of magnesium fertilizer could contribute to the improvement of tobacco internal quality. |
