以岗优188和南粳9108为材料，研究了泥质法露天育秧、营养土露天育秧和营养土工厂育秧3种育秧方式对秧苗素质及产量性状的影响。结果表明，不同育秧方式对供试品种的大田生育期并无明显影响；泥质法露天育秧所育秧苗茎基宽最高，但秧苗叶面积最小，营养土工厂育秧所育秧苗的地上部鲜质量和干质量明显高于泥质法露天育秧；泥质法露天育秧所育秧苗根数最多，但根鲜质量和根干质量以营养土露天育秧最高；产量方面，2个供试品种均以泥质法露天育秧最高，其次是营养土露天育秧，营养土工厂育秧最低，泥质法露天育秧产量较高的原因在于其每穗总粒数和结实率较高。

In order to develop a suitable seedling raising method, an experiment was conducted to study the effects of soil open seedling raising, nutrient soil open seedling raising and nutrient soil factory seedling raising methods on seedling quality and grain yield, using Gangyou188 and Nangeng 9108 as materials. The results showed that the different seedling raising methods had no significant effects on the growing stage, but had significant effects on seedling quality and grain yield. The base width of the seedling by soil open seedling raising method was the widest, but the leaf area was the lowest, the fresh and dry weight of aerial part of seedling, the fresh and dry weight of seedling root were lower than that of nutrient soil open seedling raising method. The root numbers of seedling by soil open seedling raising method was the most. The grain yield of rice by soil open seedling raising method was the highest, and the yield of rice by nutrient soil factory seedling raising method was the lowest. The reason for the high yield of rice by soil open seedling raising method were depended on the higher numbers per panicle and seed setting rate.
