In order to determine the effect of different temperature, sowing depth and seeding rate on the emerging ability, yield and yield composition of rice direct sowing. In order to analyze the effect of temperature, sowing depth and seeding rate on the yield of the dry direct seeding on "changbai25" and "jijing88". The results showed that the emerging ability decreases with the increase of sowing depth and increases with the increase of temperature. Whenthe sowing rate was 60 kg/ha, the yield of the rice was the highest, as the amount of seeding rate continues to increase, the yield decreases.
