摘　　要：对10份大豆新品种进行冬季田间种植试验,以筛选出适宜在云南省泸水市种植的冬大豆品种。每个品种的小区面积10 m^(2),种植密度1.8万株/亩(1亩≈667 m^(2)),以本地品种作为对照(CK),对9个大豆新品种进行生育期、农艺性状、产量等比较。结果显示:中豆41的丰产性、抗逆性、商品性等综合性状都优于其他9个品种,理论产量达289.8 kg/亩,比本地品种高44%,可在泸水区域冬季推广。并非农艺性状指标越高产量越高,适度的生育期、适中的植株高度和底荚高以及较高的百粒重、有效分枝和单株有效荚数才是高产的关键,建议泸水市的冬大豆播种期不宜早于12月上旬,以免在大豆花荚期遭遇冷害影响。Ten new soybean varieties were subjected to winter field planting trials to select suitable winter varieties in Lushui City, Yunnan Province. The plot area of each variety was 10 m^(2), the planting density was 18,000 plants·mu^(-1)(1 mu≈667 m^(2)), and local varieties were used as controls(CK) to compare the fertility, agronomic traits, and yield of the nine new soybean varieties. The results showed that the comprehensive characteristics of Zhongdou 41, such as productivity, stress resistance, and commercialization, were better than those of the other nine varieties. The theoretical yield was 289.8 plants·mu^(-1), which was 44% higher than that of local varieties, and it could be popularized in the winter in the Lushui area. Not the higher the agronomic trait index, the higher the yield, moderate fertility, moderate plant height, and bottom pod height, and high 100-grain weight, effective branching, and effective pods per plant is the key to high yield, it is recommended that Lushui City, winter soybean sowing should not be earlier than the first ten days of December, so as not to encounter the impact of cold damage in the soybean flower and pod stage.
