摘　　要：[目的]为选择适应水稻机插作业的育秧方式和提高机插杂交中籼稻产量提供理论基础和技术支持。[方法]以徽两优6号为供试材料,研究营养土软盘育秧、流水线营养土硬盘育秧、淤泥软盘育秧3种育秧方式对机插秧水稻秧苗素质和产量性状的影响。[结果]流水线营养土硬盘育秧秧苗素质表现出较强的优势,成苗率较高,漏插率较低,茎基部较粗,根系盘接力较高,根系活力较强,缓苗期较短,产量优势明显,理论产量和实际产量分别高于其他育秧方式。[结论]在安徽省江淮地区,采取流水线营养土硬盘育秧有利于提高水稻机插秧的秧苗素质,建立合理的群体起点,形成较高的产量。[ Objective] The aim was to provide a theoretical basis and technological support for choosing the suitable seedling raising method of mechanical transplanted rice and improving the yield of hybrid indica rice in mechanical transplanting. [ Method] A comparative experiment on plastic disk seedling with nutritive soil, hard disk on seedling assembly line with nutritive soil, silt-raised seedling with plastic disk was con- ducted on to study the influences of different seedling methods on seedling quality and yield traits of mechanical transplanting rice Huiliangyou No. 6. [ Result] The results showed that the hard disk on seedling assembly line showed a great advantage with higher seedling rate, lower miss seedling rate, thicker stem base width, higher root power, lower recover period, and its theoretical yield and actual yield were higher than those of the other seedling raising methods. [ Conclusion] Based on seedling quality and yield traits of mechanical transplanting rice, the hard disk on seedling assembly line is suitable for building reasonable starting point of rice population and higher yield in Jianghuai region, An- hui Province.
