摘要
为探究光合细菌与留叶数互作对烤烟生理生化及产量和质量的影响,以‘云烟87’作为供试材料,采用双因素裂区试验(光合细菌浓度:1:500、1:300、1:100;留叶数:19、21、23片)研究两者及其互作效应对烤烟光合特性、碳氮代谢特性、化学成分及经济性状的影响。结果表明,光合细菌浓度为主要效应因子,在1:300浓度下显著提高了烟叶叶绿素含量,并促进了类胡萝卜素类和苯丙氨酸类等降解产物的生成,感官质量和经济表现也较好。与其余处理相比,光合细菌浓度1:300和留叶数21片处理的叶绿素含量增加了21.47%,中性致香物质含量增加了4.23%~5.04%,产值增加了6.95%~8.70%,上等烟比例提高了3.05%~6.13%,感官质量得分最高。综上,光合细菌喷施浓度1:300且留叶数21片处理能够改善烟叶品质,优化等级结构,提高经济效益。
In order to explore the effects of the interaction between photosynthetic bacteria and the number of retained leaves on the physiology,biochemistry,yield and quality of flue-cured tobacco,ʻYunyan 87ʼwas used as the test material in this study,and a two-factor split-plot experiment(photosynthetic bacteria concentration:1:500,1:300,1:100;the leaf retention number:19,21,23 leaves)was conducted to study the effects of the two and their interaction on photosynthetic characteristics,carbon and nitrogen metabolism characteristics,chemical composition and economic traits of flue-cured tobacco.The results showed that the concentration of photosynthetic bacteria was the main effect factor.At the concentration of 1:300,the chlorophyll content of tobacco leaves was significantly increased,and the formation of degradation products such as carotenoids and phenylalanine was promoted.The sensory quality and economic performance were also better.Compared with the other treatments,the chlorophyll content of the treatment with photosynthetic bacteria spraying concentration of 1:300 and 21 retained leaves increased by 21.47%,the neutral aroma content increased by 4.23%-5.04%,the output value increased by 6.95%-8.70%,the proportion of first-class tobacco increased by 3.05%-6.13%,and the sensory quality score was the highest.In summary,the treatment with photosynthetic bacteria spraying concentration of 1:300 and 21 retained leaves can better improve the quality of tobacco leaves,optimize the grade structure,and improve economic benefits.
