摘　　要：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。Study on the efficent seed production technics of sugarbeet monogerm variety from diferent parents plants cultivated density,various growth regulator,and changed ratio of parent plants.The results as follow:it is economical and justified that cultivated density of sugarbeet seed production with row spaciug and plant distance is 60cm×50cm.The maternal and paternal cultivated ratio is 1∶5,which either increases soil usage and seed reproduction amounts or effictively decreases cost as well as increases economic profits of seed production.
