Structure and seeding theories of the rice precision needle-like vacuum seeder was introduced. The experimental results for hybrid rice indicate that the seeder is capable to meet the requirement of precision seeding and low rate of damaged seed. The analyses of the experimental results indicate that the vacuum value is the most important factor, the angle of the needle top and rotate speed of the roller follow. The optimum operation condition with the level of factors as follows: vacuum value 4.8kPa, the angle of the needle top surface 30°and rotate speed of the roller 5r/min.
