The method comprises the following steps: (1) no-tillage rice bottom mixed planting of Astragalus sinicus and Raphanus sativus L； (2) late rice harvesting； (3) field management； (4) ploughing back to the field. al, ploughing period: According to the local early rice production season, ploughing before that first 15 day of rice transplanting, during which Astragalus sinicus enters full florescence stage, and Raphanus sativus L enters flower pod stage； a2, ploughing method: using dry tillage method to plough back to the field. Before ploughing, applying straw rotpromoting agent, 1.5 ~ 2.5kg / mu. Then, Astragalus sinicus and Raphanus sativus L in the fertilizer field were turned over together, ploughed 15 ~ 20cm deep, then sunned for 2 ~ 3d, then irrigated and harrowed, and then early rice could be planted. In that invention, the Astragalus sinicus and the Raphanus sativus L are mixed, the input of chemical fertilize in early rice planting can be reduced after ploughing to the field, and the rice field is no-tillage, the Amethyst sinense and Raphanus sativus L are mixed, which save labor and costs and improves labor productivity.
