This invention relates to the field of hybrid rice seed production technology, specifically providing a method for mechanized hybrid rice seed production involving the simultaneous, staggered sowing of male parents in the same seed tray. The method involves sowing the male parents twice in the same seed tray according to a predetermined sowing date difference. Seedling growth is controlled by supplemental blue light or tebuconazole soaking, reducing the competitive advantage of the first-time sown male parent and minimizing the growth difference between the two sown male parents while maintaining leaf age differences. This achieves the goal of mechanized planting of hybrid rice with male parents from two different periods simultaneously without altering the growth cycle. Only one seed tray is needed for transplanting, simplifying the operation process. Conventional rice transplanters can be used for simultaneous, mechanized planting of hybrid rice parents, enabling single-row planting of multiple male parents in one row. This reduces the area occupied by male parents in the seed production field, improves production efficiency, saves labor resources, and is suitable for large-scale operation in large-scale seed production bases, reducing labor costs.
