Effect of Field Propagation Technology of Indigenous Bacteria on the Quality of Tobacco Leaf

[目的]研究土著菌田间扩繁技术对烟叶质量的影响,探讨进一步降低化肥施用量的可行性。[方法]于2016年在费县试验田以NC102为研究材料,设置T1、T2、CK(对照)3个处理,研究不同处理对农艺性状、经济性状、烟叶外观质量和感官质量的影响。[结果]施用土著菌处理的烟株长势良好,在农艺性状方面,有效叶数较多,抗病性能较高,叶面积较大,组织结构好,田间整齐度较高;在经济性状方面,T2处理最优,产量、均价、产值等各项经济指标均最高,其次是T1处理,CK组各项指标均最低;原烟外观质量方面,2个土著菌处理烟株烤后烟呈橘黄色,烟叶油分有,组织结构疏松,优于CK组;在感官质量方面,2个土著菌处理香气质稍提升、杂气减轻、刺激性降低,余味有所改善,整体感官质量提升,优于CK组。[结论]土著菌田间扩繁技术对于提高烟叶质量具有显著的影响。

[Objective]To study the effect of field propagation technology of indigenous bacteria on the quality of tobacco leaf,we discussed the feasibility of further reducing the amount of chemical fertilizers. [Method]NC102 were used as the research material in the trial field of Feixian in 2016,we set three different processes T1、T2 and CK（ control） to study the effects of different treatments on the agronomic traits,economic traits,appearance quality and sensory quality of tobacco leaves. [Result]The tobacco plants treated with indigenous bacteria grew well. In the agronomic traits,the effective leaf number was more,the disease resistance was higher,the leaf area was bigger,the organization structure was good,the field uniformity was higher. In the economic traits,T2 was the best,yield,average price,output value of area yield and other economic indicators were the highest,the followed was T1,yield,average price and output value were the lowest in the control group. In the aspects of the original smoke appearance quality,two processing groups of tobacco plants were roasted in orange,tobacco leaves had the oil content and the structure was loose,which was superior to the control group. In terms of sensory quality,the two treatments were slightly improved,the miscellaneous gas was reduced,the irritation was reduced,the aftertaste was improved,and the overall sensory quality was improved,which was superior to the control group. [Conclusion]The field propagation technology of indigenous bacteria has a significant effect on improving the quality of tobacco leaves.
