Traditional millet drilling method has a problem of labor-intensive artificial thinning-out, so a negative-pressure precision millet seed-metering device was designed to realize millet precision dibble seeding. Single factor experiment researches effect of rotational speed and air-chamber vacuum of seed-metering device on its seed-metering passing rate, repeat-sowing rate and leak-sowing rate. By means of orthogonal experiment method, optimal parameters of seed-metering device were defined, which was 20 r/min rotational speed, 4 mm bore diameter, 1.5 KPa air-chamber vacuum and 55 mm air cut valve arc length. The field test result shows that the seed-metering device meets completely standards of “Single-seed (Precise) Seeder Technological Requirements” and agronomic requirements.
Key words: Millet, negative-pressure, orthogonal experiment, precision, seed-metering device, ,
