In order to select the suitable sowing method for direct seeding rice, the effects of dibbling and broadcasting on emergence rate, seedling rate, tillering dynamics, tiller number, dry matter accumulation in heading stage and maturity stage, yield and yield components were compared under water direct seeding and dry direct seeding, using hybrid rice Chuanyou 6203 and conventional rice Jinnongsimiao as materials. The results showed that, compared with dry direct seeding, the emergence rate of water direct seeding was lower, but seedling rate and yield were higher. On the other hand, hill-drop drilling rice performed better than broadcast-sowing rice on seedling growth, population quality, dry matter accumulation and yield.
