生石灰施用量对彭水地区烟草农艺性状及内在品质的影响
摘要 [目的]分析生石灰施用量对烟草农艺性状及烤后烟叶品质的影响。[方法]采用田间小區试验研究了不同生石灰施用量对烟草生育期农艺性状、烤后烟叶化学成分及评吸质量的影响。[结果]在该试验条件下，生石灰施用量为1 500 kg/hm2时，烟草长势最好，施用量1 125 kg/hm2次之；施用量1 875 kg/hm2时烟草长势较差，但优于对照。施用生石灰能够增加总糖、还原糖、烟叶钾、糖碱比、总氮、烟叶氯的含量，降低烟碱含量。生石灰的施用能够增加烤后烟叶香气质、香气量，提高评吸质量。[结论]施用生石灰有利于提高烟叶质量，施用量以1 500 kg/hm2较优。

Abstract [Objective] To analyze the effects of the application rate of quicklime on the agronomic traits of tobacco and the quality of roasted tobacco leaves. [Method] A field plot experiment was conducted to study the effects of different application rates of quicklime on the agronomic traits of tobacco growth period， the chemical composition of tobacco leaves after baking， and the smoking quality. [Result] Under the experiment conditions， when the application amount of quicklime was 1 500 kg/hm2， the growth vigor of tobacco was best， followed with 1 125 kg/hm2 application amount；when application amount was 1 875 kg/hm2， the growth vigor was relatively poor， which was still better than that of control. The application of quicklime could increase total sugar， reducing sugar， potassium leaf， sugaralkali ratio， total nitrogen， and chlorine content of tobacco leaves， and reduce the content of...
