Abstract:Base on the fact that vibration improves the material flow characteristic, a small-type vibrated seeding apparatus for rice bud seeds was designed which is suitable for hilly areas. To find the optimum vibration parameter, seeds of rice cultivar ‘Huaidao No.6’ were selected to investigate the influence of amplitude, vibration frequency and amplitude angle on bud damage rate, seeding volume and seeding uniformity by single factor and multi-factor test. The results showed that when the amplitude is 0.9 mm, the vibration frequency is 60 Hz and the amplitude angle is 8°, stable seeding volume and good seeding uniformity are obtained with bud damage rate maintaining at low level, which meet the requirements of rice bud seeding.
