[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 research aimed to investigate the effects of the doses of strong seedling agent on the quality and yield of rice seedlings. [Method] With Yongyou 9 and Huanghuazhan as test materials, the effects of four strong seedling agent doses on quality and yield of late rice replanting seedlings were investigated. [Result] With the increase of dose of strong seedling agent, the leaf age, basal stem width and dry matter of seedling increased more than the control. And strong seedling agent seedling rice yield increased, mainly for the effective panicles and grains per panicle increased. [Conclusion] The strong seedling enhancer could effectively improve the quality of seedlings and increase the yield. Under the test conditions, the best seedling enhancer was 50 g / m2.
