In order to realize the nursing seedlings of super rice, a type of vacuum-vibrating tray precision seeding device was designed. The super rice Changyou 3 was selected, the effects of relative pressure, diameter of suction hole, vibration frequency of plate, amplitude, the suction distance on seeding performance was analyzed with a five-factors and four-level orthogonal experiment. A mathematical model was established between seeding device parameters and seeding performance index, which provided the basis for the parameters selection of the precision seeder device in seeding process. The multi objective optimization genetic algorithm was made and the optimal parameters were determined as: vacuum negative pressure value of 3.68kPa, diameter of suction hole of 1.84mm, vibration frequency of 10.90Hz, amplitude of 4.09mm, the suction distance of 3.92mm which were verified by experiments. Through seeding test of the long type super rice, the results were consistent with theoretical analysis, which showed that the seeding device had a good adaptability to different varieties of super rice, which were suitable for different varieties of super rice seeding. Through sowing and seedling test, the seeding device could meet requirements of super rice planting seedling.
