摘　　要：大豆密植栽培技术是提高产量的重要措施。文章以小粒大豆品种克豆48和绥小粒豆2号为试验材料,于2018—2020年及2022年进行种植密度试验。结果表明,种植密度为50万株/hm^(2)时,克豆48产量最高,较种植密度为30万株/hm^(2)时增产17.2%;2022年种植密度为37.5万株/hm^(2)时,克豆48产量较对照品种绥小粒豆2号增产14.7%。综上,克豆48适宜密植栽培,可作为耐密植品种推广。The soybean dense planting cultivation technique was an important measure to improve soybean yield.The article conducted planting density experiments on small grain soybean cultivars Kedou 48 and Suixiaolidou 2 from 2018 to 2020 and 2022.The results showed that when the planting density was 500000 plants/ha,the yield of Kedou 48 was the highest,increasing by 17.2%compared to when the planting density was 300000 plants/ha;When the planting density was 375000 plants/ha in 2022,the yield of Kedou 48 increased by 14.7%compared to the control variety Suixiaolidou 2.In summary,Kedou 48 was suitable for close planting cultivation and could be promoted as a tolerant cultivar for close planting.
