The invention relates to a manufacturing method of tobacco water content detection standard sample and steps for applying to calibrate an oven, and is characterized in that, when the feed level is the same level in the same region only, the method comprises the following steps: sampling in the tobacco box at the packing pre-pressing place, removing the impurity from the sample, separating the peduncle leaves, removing the tobacco peduncle, taking the leaves and crushing through the whirlwind grinder, sieving, after mixing symmetrically by using the sampler, collecting in the sealed container,discharging the air, after a period of time, adequately symmetrically mixing the samples, respectively detecting the samples by all ovens according to the 'oven method', and then calculating the average water content rate of all detected samples, wherein the average valve is determined as the standard water content rate, the prepared sample is the standard sample, and the prepared standard sampleis used for calibrating th
