运用振动改善物料流动特性的原理,设计了一种宜于在丘陵地区使用的小型振动式水稻芽种直播装置。以‘淮稻6号’为试材,通过单因素和多因素正交试验,考查振幅、振动频率、振动倾角等3个振动参数对伤芽率、播量、排种均匀性变异系数的影响。结果表明,在振幅为0.9 mm,振动频率为60 Hz,振动倾角为8°时,播量稳定,排种均匀性好,且伤芽率能维持在较低的水平,可满足水稻芽种直播的要求。

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 th...
