The invention relates to a method for producing and planting KRK26 tobacco in a high-altitude mountainous region, and belongs to the technical field of production and planting of flue-cured tobacco. The method comprises the following key steps: field management including land selection, ridging and transplanting, fertilizing, pine needle covering, ridging and the like and ripening and harvesting.A mountain tobacco planting area with relatively high sand content, sufficient light, heat and water and an altitude of 1900-2100 m is selected, ridging is carried out according to requirements, fertilizers are applied reasonably, nitrogen is controlled, phosphorus is stabilized, and trace fertilizers are increased and supplemented; the transplanting period is generally April 10th to April 20th ,and the field growth period is ensured to be about 150 days; 4-7 kg of pure nitrogen is applied per mu according to different fertility levels, soil moisture surface is covered with pine needles, and500-800 kg of the pine needles are used per mu; and proper field management is carried out, topping is carried out in good time, and the tobacco is harvested when the tobacco is ripe. According to theKRK26 which is produced and planted by the method, the output value per mu and the proportion of middle and upper grade tobacco are effectively improved, the quality of tobacco leaves is good, and the industrial usability is high.
