摘　　要：采用正交试验设计,研究了品种类型、密度、种植方式三因素对大豆产量的影响。结果表明:品种是夏大豆产量及各农艺性状的主要影响因素;三因素对夏大豆产量影响强度的顺序是品种>密度>种植方式;在本区生态条件下,获得夏大豆最高产量的理论组合为:品种为有限类型沧豆6号、密度1.6万株/667 m2、种植方式为40 cm行距。With the orthogonal experimental design, the influences of 3 factors： variety, density and planting pattern on yield of summer soybean were investigated. The result indicated that variety was the primary factor on yield and agronomic characters in summer soybean. The order of 3 factors on yield was variety 〉 density 〉 planting pattern. The best approaches to gain higher yield in the area were determinate variety Cangdou No. 6 with density of 16,000 per 667 m2 and 40 cm row spacings.
