摘　　要：不同床土调制剂对秧苗素质影响的研究结果表明:不同床土调制剂对秧苗素质有不同程度的影响。在6个处理中以第5处理秧苗素质最佳,其根数、根长、单株分蘖数、百株地上部干重都好于其它5个处理;叶龄、茎粗和最长叶片宽度与处理3基本相同也好于其它4个处理,且能很好地预防立枯病的发生。其次为第3处理,叶龄、最长叶片宽略高于第5处理,根数、单株分蘖数、百株地上干重仅次于第5处理,也能很好地预防立枯病的发生。但处理3秧苗矮只有10.38 cm,根长也较其它5个处理短,但最长叶片宽却高于其它5个处理,说明处理3对秧苗的生长起到了矮化抑制作用。Effect of dispensing agent on rice seedling quality were researched and the result indicated that dispensing a- gent had different effects on seedling quality. Among 6 treatments, treatment 5 had best seedlingquality,its root number, longest-leaf-width, tillers per plant and 100-plant dry weight were better than other 5 treatments, leaf age, stem diame- ter and longest-leaf-width of treatment 5 were fundamentally the same as treatment 3 and were also good for helping prevent Damping-off. Followed by treatment 3, its leaf age and leaf width just above treatment 5, the root number, tillers per plant and 100-plant dry weight after treatment 5 and were also good for helping prevent damping-off. But seedling height of treatment 3 was only 10.38cra and the root length was also shorter than others, but longest-leaf-width was higher than others, so it show that treatment 3 had inhibition on the growth of seedling.
