| Abstract: |
| In order to obtain the optimal working parameters of the potato seeder with fertilization and mulching, a study of performance was carried out through changing the 4 major operational parameters as machine speed, line speed of rotary blade, speed of auger shaft and angle of disk coverer. The seeding rate and the thickness of the covering soil with plastic film were evaluated. Combined the orthogonal experiment, the optimal combination of each working parameter was obtained by applying the comprehensive evaluation method. The machine advancing speed of 0.65 m·s-1, line speed of rotary blade of 0.90 m·s-1, speed of auger shaft of 950 r·min-1, angle of disk coverer of 35° were the optimal combination of operating parameters. According the optimal combination of operating parameters, the experiment results showed that under the optimized test conditions the average seeding was 92.6% and the average thickness of the covering soil by plastic film was 40.1 mm, which meets the technical specifications of quality evaluation of potato seeder with fertilization and mulching. |
