发酵饼肥对烤烟产量质量和效益的影响

实验表明，施用发酵性饼肥，可促进烟株生长发育，提高烟叶产量，改善烟叶质量和增加上等烟比例。从烟叶化学成分分析进一步表明，随着发酵饼肥用量的增加，中部烟叶烟碱和氮含量呈增加的趋势，而总糖和还原糖呈下降的趋势：上部烟叶中烟碱氮含量差异不明显，总糖和还原糖呈降低趋势，表明施用发酵饼肥，可增加中部烟叶的厚度，提高上等烟叶比例，对改善烟叶质量具有明显的效果。

Effect of The Fermented Oil-cake Fertilizer on Yield and Quality of Flue-cured Tobacco Leaves

The research indicated that application of oil-cake fermented could promote the growth of flue-cured tobacco plant, enhance leaf yield, improve leaf quality. Chemical analysis of content of tobacco leaves showed that with the mount of oil-cake fermented increasing, the nicotine and nitrogen of tobacco leaves trend increase, but total sugar and reductive sugar trend decrease in middle leaves, however, in top leaves the difference of nicotine and nitrogen was not obvious, total sugar and reductive sugar still tended to decrease. So applying the oil-cake fermented, the leaves could be thicken in middle leaves, ratio of high quality level leaves be increased, general quality of tobacco leaves be improved.
