The warming device for the seedling raising shed consumes electric energy and does not pollute the environment; meanwhile, the temperature increasing device can enable the temperature of the air blown out from each part of the top of the seedling raising shed to be equivalent, so that the temperature in the seedling raising shed can be uniformly distributed, and the tobacco seedlings in the seedling raising shed can grow at the optimum temperature; in addition, the temperature increasing device not only can unidirectionally increase the temperature in the seedling raising shed, but also can adjust the temperature in the shed when the temperature is relatively high in summer and the seedling raising shed is comprehensively utilized in a leisure period, so that the use efficiency of the seedling raising shed is improved.
