| Abstract: | The results of this study are summarized as follows: The content of exchangeable magnesium in the soil of main tobacco planting districts, Fujian Province varied from 0.2 to 0.5 cmol·kg -1 , content of magnesium in tobacco leaves was 0.18% in average. Available boron in tobacco planting soil was 0.22 mg·kg -1 in average, In tobacco leaves available boron was 11.05 mg·kg -1 in average. Most of the soil and tobacco leaves were short of magnesium and boron. In the way of applying 225 kg MgSO 4·7H 2O and 1125 kg 0.1% borax per hectare, content of magnesium and boron in tobacco leaves, weight of an upper and middle part leaf, quality and yield could be increased and improved. |
