Therefore, the cost of production can be reduced. Consequently, the problem of labor lack can be resolved. To seed various corps smoothly, the seeding machines may need different feeding mechanisms. In order to accomplish nearly precision planting for onion bulbs, this study designed and implemented curved plates that are used for single feeding. To simulate seeding condition in different operating speeds, the study designed one suitable static state test set that used a variable motor. The results show that the percentage of successfor seeding of screening bulbs（shorter diameter 11-16mm ）was above 91.3%. When the operating speed was below 2.27km/hr, the percentage of success in seeding maintained about 93.1% under test speed among 1.2km/hr and 1.89km/hr. The velocity had slight effect on it. The seeding intervals were about 10㎝ and standard deviation was between 0.91㎝ and 0.79㎝.
