The invention relates to a method for detecting the optimal placement position of cigarettes in a constant-temperature and constant-humidity box, and belongs to the technical field of cigarette balance. The method comprises: evenly placing three trays in a clamping groove in the constant-temperature and constant-humidity box from top to bottom at intervals; arranging two measuring points at the front left part and the rear right part of the upper layer; the middle layer being provided with a measuring point at the geometric center; arranging two measuring points at the front right part and therear left part of the lower layer; 2 hours after the constant temperature and humidity box reaching a preset temperature and humidity condition, performing measurement, and performing continuous measurement for 10-15 hours; wherein the direction of the maximum wind speed in each measurement point is taken as the final actual measurement direction of the position; calculating the airflow velocityuniformity and the airflow
