Nitrogen-reduction fertilizing method capable of improving utilization rate of flue-cured tobacco nitrogenous fertilizer in rainy and smoky area

The invention relates to a nitrogen-reduction fertilizing method capable of improving the utilization rate of flue-cured tobacco nitrogenous fertilizers in a rainy and smoky area, The nitrogen-reduction fertilizing method is characterized by uniformly applying a basal fertilizer to small holes on the day when the flue-cured tobaccos are transplanted, wherein the basal fertilizer is prepared from organic fertilizers of decomposed cake fertilizer and decomposed pig manure, an inorganic fertilizer potassium nitrate and a flue-cured tobacco special compound fertilizer containing 13% of N, 9% of P2O5 and 14% of K2O and superphosphate. When tobacco leaves completely cover the tobacco ridges and positions for digging ponds and fertilizing planted tobaccos, and water drip lines at the periphery of the flue-cured tobacco are outside the position for fertilizing basal fertilizer to the small holes, the steps of film uncovering, earthing up and top dressing can be carried out; potassium nitrate and potassium sulfate are
