Shen X.H., Shen J., and Shen H.Z., 2025, Adaptability of drill seeding and broadcast seeding in rice-wheat rotation systems, Bioscience Methods, 16(1): 33-40 (doi: 10.5376/bm.2025.16.0004)

This study evaluated the compatibility and effectiveness of drill seeding and broadcast seeding in rice-wheat rotation systems, comparing their impacts on crop yield, resource use efficiency, and environmental sustainability. The results indicated that drill seeding, implemented through mechanized seed drills, significantly enhanced productivity, reduced labor requirements, and improved water and nitrogen use efficiency. In contrast, broadcast seeding, while simpler and requiring lower initial costs, generally demanded higher seeding rates and resulted in uneven seed distribution, leading to lower resource use efficiency. The study also highlighted key challenges such as weed management, residue handling, and socio-economic barriers. Future research should focus on improving mechanized technologies, enhancing environmental adaptability, and addressing socio-economic constraints. This study aims to provide scientific evidence for the long-term sustainable development of rice-wheat rotation systems.
