摘要
１９９７年在河南省襄城、宜阳和郏县进行了烤烟施镁量试验，结果表明，随镁用量增加，烟叶含镁量增加，钙镁比下降。在豫中地区施镁对烟叶氮、磷、钾影响不明显；在豫西地区施镁对烟叶氮、磷含量影响较小，烟叶含钾量在镁用量０～３０ｋｇ·ｈｍ－２（ＭｇＯ）范围内呈上升趋势。试验结果表明，镁用量在２５～３０ｋｇ·ｈｍ－２（硫酸镁用量７５～９０ｋｇ·ｈｍ－２）时，烟株生长良好，产量、质量最佳。
A study was carried out on the effects of magnesium application on the growth,contents of main nutrients,yield and quality of flue cured tobacco.The results showed that the content of magesium increased and the ratio of calcium and magnesium in the tobacco leaves declined with the increasing of the magnesium level.There was little variation in the contents of nitrogen,phosphorus and potassium in tobacco leaves with magnesium application in central Henan Province.The contents of potassium in tobacco leaves increased with the increasing of magnesium within a range from 0～30kg·hm -2 in the west of Henan Province.The suggested application rate was 25～30 kg·hm -2 MgO at which both high yield and quality tobacco could be harvested.
