为筛选出适宜河西灌区种植的产量水平高、熟期适宜的大豆新品种，以中黄30为对照品种，对引进的9个大豆新品种在临泽县进行了引种筛选试验。结果表明，庆科豆6号表现最好，不仅较对照品种中黄30早成熟2 d，而且其单株粒数、单株粒重、百粒重较对照品种中黄30分别增加4.72%、8.18%、7.44%；平均折合产量最高，为3 703.9 kg/hm2，较对照品种中黄30增产8.11%。武豆15326表现较好，较对照品种中黄30晚熟8 d，平均折合产量为3 592.8 kg/hm2，较对照品种中黄30增产4.86%。综合考虑认为，庆科豆6号、武豆15326可作为中黄30的替代品种在临泽县大豆生产中进行推广种植。

To select new soybean varieties with high yield and suitable growth period for cultivation in the Hexi Irrigation Area, a screen experimenton 9 soybean new varieties was conducted in Linze County using Zhonghuang 30 as the control variety. The results showed that Qingkedou 6 showed the best performance, maturing 2 days earlier than the control variety Zhonghuang 30. Additionally, the number of grains per plant, grain weight per plant, and 100-grain weight of Qingkedou 6 were 4.72%, 8.18%, and 7.44% higher than those of Zhonghuang 30, respectively. Its average yield was also the highest at 3 703.9 kg/ha, an increase of 8.11% compared to Zhonghuang 30. Wudou 15326 also performed well, maturing 8 days later than the control variety Zhonghuang 30, with an average yield of 3592.8 kg/ha, an increase of 4.86% compared to Zhonghuang 30. Overall, Qingkedou 6 and Wudou 15326 can be recommended as alternative varieties to Zhonghuang 30 for soybean production in Linze County.
