In order to solve problems that traditional mechanical wheat seed-metering device has defects such as poor seeding uniformity and consistency, instability and high seed-injuring rate, a kind of pneumatic wheat precision seed-metering device is designed. The seed-metering device with internal and external circular tube grip seeds in vertical slit of the external circular tube by the negative pressure of the internal circular tube. We optimized slit width, rotating speed and negative pressure of the seed-metering device by the orthogonal experiment. In the field, we did contrast experiment through contrasting the existing mechanical seeder for wheat and measured and analyzed seeding uniformity, seedling emergence rate, consistency of each line seeding quantity, stability of total seeding quantity and rate of damaged seeds of the seed-metering device. The experiment data shows its each seed distance variation coefficient increases more 20% than current domestic mechanical wheat seed-metering device and its seeding uniformity gains obvious improvement.
Key words: Field experiment, pneumatic, precision, seed-metering device, slit, wheat,
