Tobacco pest situation monitoring method in smoke storage warehouse nitrogen filling and adjusting mode

The invention discloses a tobacco pest situation monitoring method in a smoke storage warehouse nitrogen filling air regulation mode, which comprises the following steps: after the air tightness of a warehouse stack position is improved, nitrogen filling is performed in a stacked stack chamber, the oxygen concentration in the stack chamber is detected, the nitrogen filling and oxygen concentration detection process lasts for 10-15 days at the same time, and the oxygen concentration in the stack position reaches the standard; in the state that the oxygen concentration is maintained to reach the standard, patrolling the lasioderma serricorne traps and the tobacco powder borers in the stack positions every two days, observing the insect feeding conditions of the two traps, and counting corresponding data; after nitrogen charging is finished and the stack is opened, a raw material smoke box is opened, a box cover is erected, a new lasioderma serricorne trapper and a new tobacco powder borer trapper are placed in
