Stable growth in grain production plays a vital role in safeguarding China's food security. Given the continued decline in arable land area and the slow increase in yield per unit area, spring maize-late rice rotation system has emerged as an effective strategy to increase annual productivity through increasing cropping frequency. As a representative paddy-upland rotation system, the maize-rice system demonstrates superior annual energy-equivalent yield compared to other rice-based systems, with the late rice season exhibiting higher yield than the single-cropping late rice system. This work reviewed the current production status of the spring maize-late rice rotation and systematically analyzed its agronomic advantages, including its impacts on soil physicochemical properties, yield stability, resource use efficiency, and greenhouse gas emission patterns. Furthermore, we discuss potential approaches for improving productivity and achieving sustainable development in this rotation system. These findings provide theoretical support for optimizing high-yield cultivation techniques and promoting the large-scale adoption of this cropping pattern.
