摘　　要：为探究不同钾肥用量对湖北来凤雪茄烟生长发育及发酵后烟叶质量的影响,以BES NO H382品种为材料,采用单一变量法进行大田试验,设置了3个处理,研究钾肥施用量对雪茄烟的农艺性状、发酵后烟叶的矿质元素、烟叶常规化学成分、中性香气成分、物理特性、烟叶灰分含量6个方面的影响。结果表明,适量的钾肥对烟株长势具有促进作用,并能降低烟碱和总氮含量,增加氮碱比,提高烟叶灰分含量,提高燃烧性,提高烟叶平衡含水率和叶质重,增大叶厚以及拉力,降低烟叶含梗率等。研究表明,来凤雪茄烟施钾量为T2~T3处理效果最佳。To explore the effect of different dosage of potassium on growth and development of Hubei Laifeng cigar and quality of tobacco leaves after fermentation,the BES NO H382 cigar varieties was selected to do field experiment by single variable method,and four treatments were set up to study the effects of applying different potassium content on agronomic traits of tobacco,mineral elements after fermentation,chemical composition of tobacco leaf,the neutral aroma composition of tobacco leaves,the physical properties,and leaf tobacco ash content.The results showed that the amount of potassium fertilizer played a promoting role in the growth of tobacco plant,and reduced the content of nicotine and total nitrogen,increased nitrogen base ratio,increased ash content,increased the combustibility.It could improve equilibrium moisture and tobacco leaf weight,increase tobacco leaf thickness and tension,and decrease the stem rate of tobacco leaf.To integrate all kinds of factors,the dosage of potassium between treatment T2 and T3 had the best effect.
