By optimizing the process of mechanical nitrogen-filling adjustment equipment the time of the oxygen concentration drops
Abstract： ，
during the mechanical nitrogen filling process was reduced. The rapid insecticidal technology for environmentally friendly protection of
tobacco leaves was researched and the killing effect of different carbon dioxide concentrations on tobacco beetles under hypoxic condi⁃
tions was verified. The results showed that by optimizing the process of the mechanical nitrogen-filling adjustment equipment the time
，
for the oxygen concentration of the tobacco leaf stack to drop to the effective insecticidal concentration could be reduced and the use
