Fuente: WIPO "tobacco agriculture" The invention discloses a fertilization method for effectively reducing exhaust of tobacco field N2O. The fertilization method comprises the steps of 1, circularly applying base fertilizer at the deeplayer; 2, applying seedling lifting fertilizer; 3, circularly applying topdressing fertilizer; 4, applying balance fertilizer. The utilization rate of nitrogen of flue-cured tobaccos can be effectively increased, the exhaust amount of tobacco field N2O is obviously reduced, the absorption of nutrients by the flue-cured tobaccos is promoted, the biomass of tobacco plants is increased, the yield oftobacco leaves is increased, the quality of the tobacco leaves is improved, the economic benefit of the tobacco leaves is increased, and the environment risk caused by nutritive residues can also bereduced.
