[目的]筛选适宜于四川省凉山烟区环境的浓香型烤烟品种,为中式卷烟的需求提供丰富的优质原料,并进一步丰富凉山烟叶香型风格,提升凉山浓香型优质烟叶的市场竞争力。[方法]采用随机区组设计,将4种浓香型烟草品种NC297、NC55、湘烟3号、K326与凉山当地主栽品种云烟85进行对比试验。参照标准YC/T142—1998调查团棵期(约移栽后25～30 d)、旺长期、现蕾期和圆顶期各处理烟株农艺性状;收获期适时采收与科学调制,按照国标42级制进行分级,分别计算产量、上等烟比例、上中等烟比例和经济效益;选取C3F(9～13叶位中部叶)烟叶样品2 kg寄送农业部烟草产业产品质量监督检验测试中心,用于测定烟叶化学成分和烟叶质量评吸等。[结果]在凉山烟区,NC55、NC297和湘烟3号比云烟85生长发育要快,叶长、叶宽、株高、叶数等高于云烟85,其产量和上等烟比例好于云烟85,且产值相对较高,但上中等烟比例和均价不能满足生产需求。烟叶总氮含量以NC297最高,与云烟85差异显著;NC55、NC297和湘烟3号钾离子含量高于云烟85,氯离子含量相对较低,糖碱比、氮碱比、钾氯比等与云烟85差异较大,说明烟叶化学成分的协调性与烤烟生长的生态条件有关。云烟85烟叶在香气质、香气量、燃烧性等方面略好于浓香型品种烟叶,然而NC55、NC297和湘烟3号烟叶劲头和浓度仍保持着自身独有的特点。[结论]在凉山烟区(典型清甜香型烟区),NC55、NC297和湘烟3号等浓香型品种生长健壮,经济效益高,所生产出来的烟叶可满足烟草工业对浓香型烟叶原料的要求,适宜在凉山地区种植。 [Objective] The research aimed to screen the fragrant type flue-cured tobacco varieties suitable for the environment of Liangshan tobacco-growing area in Sichuan Province, provide rich high-quality raw materials for the demand of Chinese-style cigarettes and further enrich the aromatic flavor of Liangshan tobacco and enhance the market competitiveness of Liangshan Luzhou-flavor high-quality tobacco . [Method] Four kinds of fragrant tobacco varieties NC297, NC55, Xiangyan No.3 and K326 were compared with Yunyan 85, a local main cultivar of Liangshan by randomized block design. Reference to the standard YC / T142-1998 investigation of the flowering stage (about 25 ~ 30 d after transplanting), Wang long, budding and domestication of tobacco plant agronomic traits; Harvest harvest timely and scientific modulation, according to national standard 42 grades were graded, were calculated yield, superior tobacco ratio, the proportion of upper secondary tobacco and economic benefits; select C3F (9 to 13 leaves middle leaf) 2 kg of tobacco samples sent to the Ministry of Agriculture Tobacco Industry Product Quality Supervision and Testing Center , Used to determine the chemical composition of tobacco leaf quality assessment and smoking. [Result] In Liangshan tobacco area, the growth and development of NC55, NC297 and Xiangyan No.3 were faster than that of Yunyan 85, and the leaf length, leaf width, plant height and leaf number were higher than those of Yunyan 85, and the yield and superior tobacco ratio were better than that of Yunyan 85 Cloud 85, and relatively high output value, but the proportion and average price of upper middle class can not meet production needs. The content of total nitrogen in leaf was the highest in NC297, which was significantly different from that in Yunyan 85. The content of potassium in NC55, NC297 and Xiang-yan No.3 was higher than that in Yunyan85, the content of chloride was relatively low, and the ratio of nicotine to base, Yunyan 85 is quite different, indicating that the chemical composition of tobacco leaves is related to the ecological conditions of flue-cured tobacco growth. Yunyan85 was slightly better than Luzhou-flavor variety in terms of aroma, aroma and combustibility. However, the tobacco leaves of NC55, NC297 and Hunan No.3 still maintained their unique characteristics. [Conclusion] In Liangshan tobacco (typical sweet-smelling tobacco-type tobacco area), strong-flavor varieties such as NC55, NC297 and Xiangyan No.3 grew robust with high economic benefits. The produced tobacco leaves could meet the requirements of the tobacco industry for the strong flavor Tobacco raw material requirements, suitable for planting in Liangshan area.
