The invention discloses a farming method for returning straw to the field locally in a corn and flue-cured tobacco rotating system. The method is applied to flue-cured tobacco and corn rotation plough land in a single cropping system and comprises the steps that firstly, corn is ridged to be cultivated, two rows of corn are planted per ridge, the height of each ridge is 30+ / -2 cm, the corn wide row spacing between every two adjacent ridges is 70+ / -5 cm, the narrow row spacing between two rows of corn on each ridge is 50+ / -5 cm, and the distance between plants is 25-30 cm; after the corn is harvested, ploughing is needless, original ridges and furrows are used, and the cut-off straw is directly spread over the furrows to be returned to the field; secondly, microorganism fertilizer is scattered on the straw, and soil on the ridges falls to the furrows for earthing and burying of the straw; in the next year, flue-cured tobacco base fertilizer is scattered in the furrows where the corn straw is buried 10-15 days before the flue-cured tobaccos are transplanted, the flue-cured tobaccos are planted in a single-row-ridge mode, the row spacing is 120+ / -5 cm, and the distance between plants is 50-60 cm; no-tillage ridge gathering is conducted towards the insides of the furrows along the two sides of each furrow, and ridges are formed for cultivating the flue-cured tobaccos. According to the farming method, the corn straw and the flue-cured tobacco straw are directly applied to the tobacco field locally, and therefore sustainable development of a tobacco region is effectively realized.
