施用中微量元素对烤烟产量和品质的影响

 本文报道了烤烟施用中、微量元素对其产量、品质的影响。结果表明,烤烟叶片产量、外观质量、烟碱、总糖、全氮及蛋白质含量与中、微量元素呈正相关关系。Mg能显著提高烟叶产量;施用中、微量元素的中上等烟比例比对照提高0.6%～3.83%。B,Mg还能改善烟叶颜色;B,Mg,Mn能显著提高烟碱含量。因此,在烤烟肥料中补充足够的B,Mg,Mn等中、微量元素是至关重要的。

Effect of Applying Medium-microelements to the Yield and Qualities of Tobacco

This paper reports the effect of applying medium microelements to the yield and qualities of tobacco.The results showed that the yield of leaves, the external qualities, the nicotine, the total sugar, the whole nitrogen and the content of protein in tobacco are correlated positively with the medium-microelements.Mg can raise the yield significantly of tobacco leaves, The ratio of medium-topped tobacco which was applied with the medium-microelements exceeded 0.6%～3.83% as compared with that of the control.B and Mg can also improve the colour of tobacco leaves.B, Mg, Mn can increase remarkably the content of nicotine.So it is very important to add proper amount of medium-microelements such as B, Mg, Mn, etc.for tobacco fertilizers.
