摘要： 本试验旨在研究行距和密度对大豆新品种‘合农76’产量及品质的影响，明确不同行距下‘合农76’最佳密度。试验采用裂区设计，主区为行距，30 cm和45 cm；副区为密度，30、35、40、45、50 万株/hm2，用D1、D2、D3、D4、D5表示。结果表明，随着密度的增加产量呈先增加再降低的趋势，产量最高的密度处理为D2，即35 万株/hm2，且不倒伏；45 cm行距下最佳密度为38.00 万株/hm2时，产量为3289.79 kg/hm2；30 cm行距下最佳密度为37.18 万株/hm2时，产量为3211.96 kg/hm2；随着密度的增加，蛋白质和脂肪含量呈逐渐降低的趋势，蛋白质和脂肪最高的处理为D1。综上所述，‘合农76’在45 cm行距下最佳密度为38.00万株/hm2，30 cm行距下最佳密度为37.18万株/hm2。

Abstract: The objective of this experiment is to study the effects of row spacing and density on the yield and quality of new bean variety‘Henong76’, and clarify the optimum planting density at different row spacing. Split spot design was conducted in the research with row spacing as the main plot, including 30 cm and 45 cm row spacing, planting density was as the sub-plot including 300000, 350000, 400000, 450000, and 500000 plants/hm2, identified as D1, D2, D3, D4, and D5, respectively. The results showed that soybean yield first increased, and then decreased with the increasing planting density. D2 treatment (350000 plants/hm2) had the highest yield compared with other treatments. Moreover, there was no lodging problem for‘Henong76’under D2 treatment. The optimum planting density was 380000 plants/hm2 at 45 cm row spacing, and the yield was 3289.79 kg/hm2. The optimum planting density was 371800 plants/hm2 at 30 cm row spacing, and the yield was 3211.96 kg/hm2. The contents of protein and fat decreased along with the increasing planting density. D1 treatment obtained the highest content of protein and fat. Taken together, for‘Henong76’, the optimal planting density was 380000 plants/hm2 at 45 cm row spacing, or 371800 plants/hm2 at 30 cm row spacing.
