机械充氮气调对不同内衬烟叶原料的防虫效果

Insect-proof Effect of Mechanical Nitrogen-filled Nitrogen on Different Lining Tobacco Leaves

[目的]研究机械充氮气调对不同内衬烟叶的防虫效果。[方法]通过机械充氮气调维持不同内衬烟叶储存环境的低氧环境(氧气浓度<2%)45 d以上,考察充氮气调对烟草害虫的防治效果及对烟叶品质的影响。[结果]机械充氮气调可以快速地将烟叶垛位氧气浓度降至有效杀虫浓度,能够完全杀灭不同内衬烟叶中各种虫态的烟草甲虫,并对烟叶感官品质无明显影响。[结论]机械充氮气调杀虫可作为烟叶预防性杀虫及虫害防治的有效技术手段推广应用。

[Objective] To study the insect-proof effect of mechanical nitrogen-filled nitrogen on different lining tobacco leaves.[Method] The low-oxygen environment (oxygen concentration <2%) of different lining tobacco storage environment was maintained for 45 days or more by mechanical nitrogen filling, and the effects of nitrogen-filled nitrogen control on tobacco pests and the quality of tobacco leaves were investigated.[Result] Mechanical nitrogen-filled could quickly reduce the oxygen concentration of tobacco leaf to effective insecticidal concentration, completely killing various tobacco beetles in different lining tobacco leaves, and had no obvious influence on the sensory quality of tobacco leaves.[Conclusion] Mechanical nitrogen-filled insecticide can be used as an effective technical means for preventive insecticidal and pest control of tobacco leaves.
