为研究新型水稻苗床调理剂“苗壮丰”对机插秧苗素质的调控效果，以7个优质水稻品种为材料，设置 喷施“苗壮丰”和喷施清水（对照）2个处理，进行露天水泥场塑盘育秧试验。结果表明，与对照相比，“苗壮丰”处理的叶龄、单株绿叶数、苗高、最大完整叶长、最大完整叶宽、茎基宽、SPAD值、白根数、百株鲜质量、百株干质量等12个秧苗形态生理性状指标显著提高，秧苗素质显著提升，但不同水稻品种之间效果不同。该新型水稻苗床调理剂为培育机插水稻壮秧提供了新途径。

In order to study the effect of a new-type rice seedbed conditioner “Miaozhuangfeng” on the quality of machine transplanted rice seedlings, 7 high quality rice varieties were selected, and two treatments （spraying rice seedbed conditioner “Miaozhuangfeng” and spraying clear water） were set up. The results showed that compared with the spraying water treatment, the leaf age, number of green leaves per plant, seedling height, maximum complete leaf length, maximum complete leaf width, basal stem width, SPAD value （SPAD1, SPAD2, SPAD1+2）, white root number, fresh matter weight of 100 seedlings and dry matter weight of 100 seedlings of the spraying “Miaozhuangfeng” treatment were significant improved, which indicated that “Miaozhuangfeng” had good effects on the seedling quality of rice in general. But among different rice varieties, the regulation range of “Miaozhuangfeng” on different characters is different. This new-type rice bed conditioner provides a new way for the cultivation of strong seedlings of machine transplanted rice.
