| 中文摘要: |
| 我国并无专门针对荞麦的播种机，荞麦生产机械化水平极低。为此，设计了2BF-3大垄双行荞麦播种机，采用45～50 cm大垄距种植，一垄双行，行距8～10 cm，种肥分施；整机质量150 kg，配套动力≥8.9 kW，不需要动力输出。田间试验证实:大垄双行荞麦播种机播量精确且可调，播深一致且可调，排种均匀性变异系数、各行排种量一致性变异系数、总排量稳定性变异系数、种子破损率分别为28.1%、1.4%、0.5%、0.1%，均较大幅度小于标准值，机具的通过性满足农艺要求。 |

| There was no special planter for buckwheat, the mechanization level of buckwheat production was very low in China. Therefor, we designed a planter (2BF-3) for buckwheat with two rows in one big ridge (45～55 cm width), and the row spacing was 8 cm to 10 cm. The seed and fertilizer will be applied into soil separately. The mass of whole buckwheat planter was 150 kg, mating power was≥8.9 kw and no need for power output. This buckwheat planter was an accurate and adjustable for seeding rate and seeding depth proved by filed experiment. The coefficient of variation for seeding uniformity, for seeding uniformity per row, for total seeding uniformity, and for the damaged seed rate were 28.1%, 1.4%, 0.5% and 0.1%, respectively, total were much lower than the standard value. This buckwheat planter was satisfied with the agronomic request. |
