Through the comprehensive evaluation of magnesium solvent in sintering , the magnesian lime was used to replace the dolomite powder as new extracting magnesium sintering solvent in the production .

白云石粉用量在1600kg/hm2时，油菜达到最高产量2518kg/hm2。此外，施用白云石粉改善了土壤的养分状况，提高了油菜植株的养分含量和养分吸收量。

The highest yield can be obtained when dolomite application was 1 600kg / hm ~ 2 . Besides , dolomite application improved soil nutrient condition , raising nutrient content and uptake of rapeseed plants .

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 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 .

因此，建议在腾冲烟区烤烟生产中使用白云石粉代替其他镁肥以及生石灰作为改善烟株缺镁以及改善土壤酸化的基础肥料。

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 .

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 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。

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。
