摘要
以5种不同浓度的B(硼)、Mn(锰)、Zn(锌)、Cu(铜)、Fe(铁)等微量元素的溶液分3次按不同数量喷施于36个处理的黑钙土盆栽试验处理的烟株上,定性定量地分析了各微量元素对烟叶烟碱,糖分含量和施木克值的影响,得出5因素对品质影响重要性按B、Mn>Cu,Zn>Fe的顺位排列。对烟碱含量影响大的是B、Zn,对糖含量影响大的是Mn和Fe。B对烟碱含量、Mn对含糖率有增加效应。施木克值作为表示糖氮平衡的指标受影响烟碱和含搪各因素的综合影响。
Five micronutrients (B, Mn, Zn, Cu, Fe) were spreaded on flue-cured tobacco planted in chernozemic soil in pods with five concentrations based in trials. The results indicated that the importance of the five micronutrients to quality was in the sequence B, Mn>Cu, Zn>Fe. B, Zn and Mn, Fe were important factors to nicotine and sugar contents respectively B and Mn could increase nicotine and sugar contents respectively. Carbon-nitrogen ratio was integratedly influenced-by these factors mentioned above.
