The invention provides a method for planting organic rice. The method comprises the following steps of: planting milk vetch, namely sowing 3.0 to 3.5kg of milk vetch seeds on each mu of land; after the milk vetch enters the initial bloom stage, ploughing and dry-hallowing the land to ensure that the milk vetch is cut into pieces and fully mixed with soil, drying in the sun for 1 to 2 days, and then irrigating water to ret green manure, wherein the retting time is 15 to 20 days; performing land preparation, namely reclaiming ditches to make rectangular land pieces after the land is flattened and the mud is molten; leveling the surfaces of the rectangular land pieces, paving films on the surfaces of the rectangular land pieces, and punching on the surfaces of the rectangular land pieces on which the films are paved after the films are paved for 1 to 3 days; planting rice seedlings in holes of the surfaces of the rectangular land pieces; keeping the rice field in a moistened state, namely keeping water which is lower than the surfaces of the rectangular land pieces in the ditches; and draining away the water and drying the field in the sun 8 to 12 days before the harvest. The method for planting the organic rice has the advantages that: the problem of organic fertilizers can be effectively solved, no weed is grown, plant diseases and insect pests are avoided, planting labor and planting cost are not increased, the high drought-resistant effect is achieved, the management is simple and convenient, the adaptability is strong, and the method is safe and reliable.
