Focuses on the rice-milk vetch rotation system in southern Anhui, its current status was in-deepth analyzed, the existing problems in its development were identified, and corresponding countermeasures were proposed. In the study area, the implementation of the rice-milk vetch rotation system was found to yield significant ecological and economic benefits. Milk vetch, used as green manure, was shown to play a role in nitrogen fixation, soil fertility enhancement, and soil structure improvement. This model was demonstrated to reduce nitrogen fertilizer application by 40% during the rice season, while increasing rice yield and quality. However, several challenges in its promotion were identified, including a decline in the cultivation area of milk vetch, unstable seed quality, inadequate cultivation management techniques, and a low level of industrialization. Based on these findings, several countermeasures were proposed: industrial support was suggested to be strengthened through financial subsidies, special research funds, and preferential policies to enhance farmers’ motivation for planting milk vetch and thereby expand its cultivation area; seed breeding and management were recommended to be improved by establishing specialized seed production bases and adopting advanced breeding technologies to increase seed purity and germination rate, enhancing system stability; a scientific cultivation technology system was advised to be promoted, including soil testing and formulated fertilization, and full-process mechanization, so as to improve rice yield and quality; and the industrialization of the rice-milk vetch system was proposed to be advanced by strengthening cooperation with enterprises, developing deep-processing products of milk vetch to enhance added value, and fostering leading agricultural industrialization enterprises to achieve large-scale planting, standardized production, and branded marketing. This study serves as a reference for the sustainable development of the rice-milk vetch rotation system in relevant regions.
