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.
