摘要
为探究叶片结构优化对宾县地区烟株生长和烟叶质量的影响,以龙江911为试验材料,在该地区宁远镇爱国村等5个试验点采取大区试验,分别测定其叶片结构优化(旺长期去除底脚叶4~6片)后的各采样点烟株的株高、叶长和叶宽等农艺性状,产量、产值等经济性状,烟碱、氯和总糖等化学成分,并对其香气质、香气量和香型等进行感官评价。结果表明,叶片结构优化后的成熟期烟株高度在114.3~117.3 cm;与未进行叶片优化相比,烤烟叶长和叶宽均有所增加,中、上等烟比例、烟叶单价上升,产值明显提高;烟叶结构优化后的中、上部叶烟碱含量以及总糖和还原糖含量整体呈上升趋势,中部叶的糖碱比整体呈增加趋势;烟叶结构优化后的氯含量呈降低趋势,而钾含量则表现出升高的趋势,感官评价总分均有所提高。综上,叶片结构优化后的龙江911烟株生长状况、产值和品质明显提升,中、上部叶化学成分更加协调,更符合工业需求,在生产中可进行叶片结构优化以提升烤烟品质。研究结果为宾县地区采取合理的烤烟栽培技术措施提供参考。
To explore the effects of leaf structure optimization on tobacco plant growth and tobacco leaf quality in Bin County area,Longjiang 911 was used as test material to conduct regional experiments at 5 test sites including Aiguo Village in Ningyuan Town,agronomic traits such as plant height,leaf length and leaf width,economic traits such as yield and output value,and chemical components such as nicotine,chlorine and total sugar were measured at each sampling point after leaf structure optimization(removal of 4-6 base leaves in boom period),and sensory evaluation was conducted on aroma temperament,aroma quantity and aroma type.The results showed that the plant height was 114.3-117.3 cm after leaf structure optimization.Compared with no leaf optimization,the length and leaf width of flue-cured tobacco increased,the proportion of medium and fine tobacco,the unit price of tobacco and the output value increased significantly.The content of nicotine,total sugar and reducing sugar in middle and upper leaves of tobacco leaves after structural optimization showed an overall increasing trend,while the ratio of sugar to alkali in middle leaves showed an overall increasing trend.After the optimization of tobacco structure,the chlorine content decreased,while the potassium content increased,and the total score of sensory evaluation increased.In conclusion,the growth condition,output value and quality of Longjiang 911 tobacco plant after leaf structure optimization were significantly improved,the chemical composition of middle and upper leaves was more coordinated,and it was more in line with industrial demand.Leaf structure optimization could be carried out in production to improve flue-cured tobacco quality.The research results provide references for taking reasonable cultivation technical measures of flue-cured tobacco in Bin County area.
