Dolomite powder dissolved As and Hg tobacco fields of the impact of small but significant increase in middle and lower leaf Cd contents and the central leaf Pb content in the lower and upper leaves decreased Pb content .

白云石粉溶田对烟叶As和Hg的影响不大，但明显增加中、下部烟叶Cd的含量和中部烟叶Pb的含量，有所降低下部和上部烟叶Pb的含量。

Therefore , it is suggested that in flue-cured tobacco production , quicklime and other magnesium fertilizers should be replaced by dolomite powder in order to improve symptoms of magnesium deficiency and soil acidification in Tengchong .

Employs when the 50kg / 667m ~ 2 dolomite powder , the tobacco neutral aroma ingredient content is highest . Employs 100kg / 667m ~ 2 dolomite powder , the content to be lowest .

施用50kg/667m~2白云石粉时，烟叶中性香味成分含量最高，施用100kg/667m~2白云石粉处理的含量最低。

Employs the 50kg / 667m ~ 2 dolomite powder to be possible to enhance the leaf tobacco fragrance ingredient total content obviously , but the amount used surpasses time 50kg / 667m ~ 2 not has effect . 7 .

施用50kg/667m~2白云石粉可明显提高烟叶香味成分总含量，但用量超过50kg/667m~2时无明显效果。

Employs the few dolomite powder can enhance the reducing sugar content , . Employs most amount of magnesium fertilizer processing sugar nicotine ratios are most reasonable . 5 . Employs the most amount of magnesium fertilizer make the highest magnesium content in tobacco .

施用适量白云石粉可以提高烟叶中还原糖含量，施用镁肥最多的处理的糖碱比值最为合理。

Employs 50kg / 667m ~ 2 the dolomite powder to be possible to raise the leaf tobacco acidic aroma ingredient content , the dolomite powder employment quantity surpasses 50kg / 667m ~ 2 will not to get up the effect .

施用50kg/667m~2白云石粉可以提高烟叶酸性香味成分含量，白云石粉施用量超过50kg/667m~2则起不到应有效果。
