The invention discloses a flue-cured tobacco seedling transplanting method. The method includes the following steps of firstly, collecting and smashing straw; secondly, conducting soil preparation and ridging; thirdly, transplanting flue-cured tobacco seedlings; fourthly, pouring root setting water; fifthly, covering the seedlings with straw and conducting dressing; sixthly, covering the seedlings with soil. The straw field returning technology is applied to the flue-cured tobacco seedling transplanting method for the first time, flue-cured tobacco seedlings can be transplanted during the low air temperature period and other unsuitable flue-cured tobacco seedling transplanting periods, the transplanting period of flue-cured tobacco can be advanced, the transplanting survival rate is increased, and the early growth and quick tillage of tobacco seedlings are promoted; soil organic matter can be increased, soil fertility is improved, soil physical properties are improved, soil tillage becomes good, and drought resistance, water logging resistance and evenness of tobacco seedlings in large fields are improved.
