摘要： 为了探索不同因素对大豆杂交制种产量影响，设计了播期、行距、父母本行数比例三因素裂区试验和播期、母本与油葵距离二因素试验，结果表明，播期对制种产量影响显著，行距、父母本行数比例，三因素之间两两互作、三者互作均对制种产量影响不显著。播期5 月10 日、行距50 cm、父本:母本=1:2 处理时制种产量最高。母本与油葵距离对大豆制种产量影响极显著。母本距油葵90 cm 处理下产量最高。结论表明，在一定范围内，较早播期、较短母本与油葵距离，可以显著或极显著地提高杂交大豆制种产量。

Abstract: In order to investigate the effects of different factors on hybrid soybean seed production, a three factors split plot experiment with the sowing time, row space and the ratio of male to female parents, a two factors random experiment with the sowing time, the distance from female rows to oil sunflower were studied. The results showed that, the sowing time had significant effects on hybrid soybean seed production，the row space，the ratio of male to female parents and the interactions had no significant effects. When the sowing time, row space and the ratio of male to female parents were May 10th, 50 cm and 1:2 parental rows respectively, the hybrid soybean seed production was the maximum output. The distance from female rows to oil sunflower had highly significant effects on hybrid soybean seed production. When the distance from female rows to oil sunflower were 90 cm, the output of hybrid soybean seed production was best. The conclusion was that the earlier sowing date and the shorter distance from female rows to oil sunflower can improve hybrid soybean seed production significantly or highly significantly in some cases.
