[目的]探究壮秧剂剂量对水稻秧苗素质和产量的影响。[方法]以甬优9号和黄华占为试验材料，考查4个壮秧剂剂量对晚稻机插秧苗素质和产量的影响。[结果]随着壮秧剂剂量的增加，秧苗的叶龄、基茎宽、干物质量等指标均较对照有所增加。而且壮秧剂育秧的水稻产量增加，主要表现为有效穗和每穗实粒数增加。[结论]壮秧剂可有效提高秧苗素质以及增加产量，且在该试验条件下壮秧剂剂量为50 g/m2时效果最好。

[Objective] The aim was to research the influence of gradient dosages of seedling-strengthening agent (SSA) on rice seedling quality and yield. [Method] The influence of four dosages of SSA on late rice seedling quality and yield was investi-gated, using Oryza sativa cv. Yongyou 9 and Huanghuazhan as test materials. [Re-sult] The results showed that applying SSA significantly increased several indexes of seedling quality including the leaf age, basal stem width and dry matter weight. In addition, SSA greatly increased the rice yield, mainly through influencing two yield component factors, effective panicle number and grain number per panicle. [Conclu-sion] SSA was beneficial to nurse strong seedling which satisfied mechanical trans-plant and improve yield. Considered both seedling quality and yield trait, the optimal SSA dosage is 50 g/m2 under this cultivating condition.
