不同氮磷钾配比对烤烟生长及产质量的影响

通过对不同的配方肥料A1，A2(氨基酸肥料)，CK(当地常规肥)的施用。根据烘烤后烟叶的产质量以及烟叶内在成分的分析比较，确定施肥效果对烟叶品质影响的研究，得出了以下结论：施用A1、A2能够明显的改善嵩明当地烟叶的产量，均价有了明显的提高;A1、A2的施用使当地的烟叶内在化学成分协调性有了很大的提高。糖碱比基本上控制在正常的范围之内。而施用CK(当地的常规肥)的烟叶，内在化学成分协调性不够好，糖碱比明显偏高，钾的含量也明显比不上A1、A2的烟叶。所以，综合考虑，A1、A2明显优于CK。

Effects of nitrogen, phosphorus and potassium on the growth and quality of flue-cured tobacco

Different formulations of fertilizer A1, A2(amino acid fertilizer) and CK(local conventional fertilizer) were applied. Based on the analysis and comparison of the yield quality of roasted tobacco leaves and the internal components of tobacco leaves, the effect of fertilization on the quality of tobacco leaves was determined. The application of A1 and A2 greatly improved the coordination of chemical components in tobacco leaves. The saccharine base ratio is basically within the normal range. However, tobacco leaves applied with CK(local conventional fertilizer) have poor coordination of internal chemical components, significantly higher saccharine base ratio, and significantly lower potassium content than tobacco leaves with A1 and A2.Therefore, after comprehensive consideration, A1 and A2 are obviously superior to CK.
