The invention discloses a fertilizing method of a Yunyan 97 cured tobacco variety. According to the method, the fertilizing amounts are controlled to 6 kg/667 m<2> of N, 6 kg/667 m<2> of P2O5 and 22 kg/667 m<2> of K2O, wherein a special fertilizer for the cured tobacco is 40 kg/667 m<2>, and the special fertilizer for the cured tobacco consists of 10% of N, 15% of P2O5 and 25% of K2O; a potassium nitrate fertilizer is 14 kg/667 m<2> and the potassium nitrate fertilizer consists of 13.5% of N and 45.5% of K2O; a potassium sulfate fertilizer is 11 kg/667 m<2> and the potassium sulfate fertilizer consists of 51% of K2O and 2 kg/667 m<2> of special medium and micro fertilizer; and farmyard manure is 500 kg/667 m<2> and an oil cake is 20 kg/667 m<2>. The fertilizing method comprises the following steps of: (1) carrying out circling fertilization of a base fertilizer in a big nest; (2) dressing the potassium nitrate fertilizer at twice; and (3) dressing the potassium sulfate fertilizer at twice. By adopting the fertilization technology, the Yunyan 97 cured tobacco variety has neat and delicate field appearance, and good and vigorous growth; in comparison with the local regular fertilization technology, the fertilizing method disclosed by the invention has the advantages that: the yield is increased for 11.43%, the output value is increased for 13.62%, and the proportion of upper-middle tobaccos is improved for 12.9%.
