The invention relates to a delayed planting method for temporary planting of tobacco seedlings, belongs to the technical field of culture of flue-cured tobacco. According to the method, a seedling raising pot is used for temporary planting of the tobacco seedlings, centralized water and fertilizer management is performed, shading is performed with a sunshade net, influence of direct strong sunshine and dry and hot air on the tobacco seedlings is avoided, and normal growth of the tobacco seedlings is guaranteed. Meanwhile, transplanting with soil is performed before a vigorous growth stage of the tobacco seedlings, completeness of root systems of the tobacco seedlings is guaranteed, vigorous growth is started rapidly, normal growth and development of the tobacco seedlings is guaranteed, and the yield and quality of the flue-cured tobacco are improved. The method is simple and convenient to operate, less cost is invested, field production can be delayed in a drought period of the flue-cured tobacco, the influence of bad climate of the field on growth of the flue-cured tobacco is avoided, and time guarantee is provided for maturity of preceding crops.
