Abstract: 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.

Key words: seedling raising methods, rice, seedling quality, grain yield
