The invention provides a tobacco feeding method for improving the uniformity of cigarette blending. The method comprises the following steps that 1, the grades of all tobacco leaves in tobacco blending are divided into three types according to sensory characteristics, wherein the three types comprise a characteristic main type A, a characteristic auxiliary type B and a characteristic cooperative type C; 2, according to the relation between the total amounts of all the types and the total amount of tobacco leaves, the feeding sequence of the types is determined; the weights of the characteristic main type A, the characteristic auxiliary type B and the characteristic cooperative type C are set to be Ma, Mb and Mc respectively, the weights of the three types are converted to the proportion relation a to b to c, the proportion relation is converted to be the integer proportion according to rounding off, the type with the maximum proportion value ranks second in feeding order, the type withthe minimum proportion value ranks third in feeding order, and the type with the middle proportion value ranks first in feeding order; 3, through a mode that the single-layer material laying area ina tobacco storage cabinet is adjusted, it is guaranteed that the proportions of the three types of all the vertical cross sections are equal or similar; 4, the tobacco leaves are fed according to thehigh-low sequence of the alkali content of total plants. According to the tobacco feeding method, the uniformity of tobacco blending is improved, so that the production uniformity of the following process is higher.
