不同氧气浓度下烟草甲各虫态活性研究

为了减少磷化氢等有毒化学物质在储烟害虫防治中的施用量,为生产上运用低氧技术防治烟草甲等仓贮害虫提供技术参考,本试验研究了低氧环境对烟草甲各虫态致死作用及对烟草甲各虫态历期的影响。结果表明,在气调贮存运用中,可以将垛内氧气浓度调至2%,经历杀虫阶段后可以将垛内氧气浓度回调至4%～6%,这样可以在有效抑制虫害的基础上,最大限度地保证烟叶的醇化质量。

Study on the activity of tobacco beetles under different oxygen concentrations

In order to reduce the application amount of phosphine and other chemical toxic substances in the control of tobacco storage pests, the rule of lethal effect on the tobacco beetle states and the history of the effect on the tobacco beetle states under hypoxic conditions are studied. Use hypoxic technology to provide technical parameters to control tobacco pests such as Tobacco. Tests have shown that: in controlled atmosphere storage, the oxygen concentration in the stack can be adjusted to <2%, and the oxygen concentration in the stack can be adjusted back to 4%-6% after going through the insecticidal stage, which can effectively suppress insect pests, To ensure maximum alcohol quality of tobacco leaves.
