摘　　要：为探索机播荠菜优质高效生产的最佳播量,更好地为荠菜种植机械化生产服务,采用双因素随机区组试验,共设置种砂(荠菜种子+黑金砂)混拌比1∶8、1∶11、1∶14和1∶17四个处理和行距14、21和28 cm 3个处理进行机器条播。结果表明,机播荠菜的农艺性状和产量随着种砂比的增加,表现出先增加后减少的趋势;行距与农艺性状和产量间相关性不显著。在12个种砂比和行距互作处理下,以A4B1(种砂比1∶17,行距14 cm)处理下的产量最高,每667 m^(2)产量可达2 230.84 kg。因此,推荐A4B1(种砂比1∶17,行距14 cm)为机播荠菜的最佳播量和行距。To explore the optimal seeding rate for high-quality and efficient production of mechanical sowing Capsella bursa-pastoris,and better serve the mechanized production of Capsella bursa-pastoris,a two factor randomized block experiment was conducted,with four treatments of seed sand(Capsella bursa-pastoris seeds+black gold sand)mixed in a ratio of 1∶8,1∶11,1∶14,and 1∶17 and three treatments with row spacing of 14,21 and 28 cm for machine seeding.The results showed that the agronomic traits and yield of mechanical sowing Capsella bursa-pastoris showed a trend of first increasing and then decreasing with the increase of seed sand ratio.The correlation between row spacing and agronomic traits or yield is not significant.Under the interaction of 12 seed sand ratios and row spacing,the highest yield was achieved under the treatment of A4B1(seed sand ratio 1∶17,row spacing 14 cm),with a 667 m^(2) yield of 2230.84 kg.Therefore,it is recommended that A4B1(seed sand ratio 1∶17,row spacing of 14 cm)is the optimal sowing amount and row spacing for mechanical sowing Capsella bursa-pastoris.
