从种株不同栽植密度、不同生长调节剂、父母本不同栽植比例等几方面研究甜菜单粒种高效制种技术。结果表明:甜菜采种栽植密度以行株距60cm×50cm经济合理。父母本配制比例以1∶5为好,既可提高土地利用率和种子繁殖量,又能有效地降低成本,增加制种的经济效益。
From the planting density of different strains, different growth regulators, the parents of different planting proportion of several aspects such as sweet potato species efficient seed production technology. The results showed that the planting density of beet seeds was reasonable and reasonable with the row spacing of 60cm × 50cm. The ratio of 1: 5 for the parents should be used to improve the land utilization rate and seed multiplication, reduce the cost effectively and increase the economic benefits of seed production.
