液体型水稻壮秧剂作用效果研究

Study on the Action Effect of Liquid Rice Seedling Strengthening Agent

以垦研017和垦香201为试验材料,以“垦研”壮秧剂为对照,设“苗壮丰”液体壮秧剂拌种、喷施2个处理,探讨不同施用方式对秧苗素质的作用效果,为液体壮秧剂在壮秧上的应用提供理论依据和技术支撑。试验结果表明:液体壮秧剂拌种、喷施处理,显著降低了秧苗的株高,明显促进了秧苗茎基宽、百株根干重,对秧苗叶龄、根数和总根长作用不明显,不同品种间表现存在差异。“苗壮丰”液体壮秧剂喷施的使用方式,可促进水稻秧苗素质的提高,更加符合黑龙江寒地稻区育秧实际需求,值得推广应用。

With Kenyan-017 and Kenxiang-201 as experimental materials and"Kenyan"strong seedling agent as control,two treatments of"Miaozhuangfeng"liquid strong seedling agent were set up,which was seed mixing and spraying,to explore the effects of different application methods on seedling quality,providing theoretical basis and technical support for the application of liquid strong seedling agent on strong seedling.The experimental results showed that seed dressing and spraying with liquid seedling strengthening agent significantly reduced the plant height of seedlings,significantly improved the stem base width of seedlings and root dry weight of 100 plants,but had no obvious effect on the leaf age,root number and total root length of seedlings,and there were differences among different varieties.The application of"Miaozhuangfeng"liquid seedling strengthening agent can improve the quality of rice seedlings,which is more in line with the actual demand of rice seedling cultivation in the cold area of Heilongjiang Province,and is worth popularizing and applying.
