夏大豆丰产增效技术研究

Research on Integrated Cultural Practices for High Yield of Summer Soybean

采用正交试验设计,研究了品种类型、栽培密度和种植方式3个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;3因素对夏大豆产量影响强度的顺序是品种类型>栽培密度>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,栽培密度2.4万株/hm2,种植方式为行距40 cm。

With the orthogonal experimental design, the influences of varieties, densities and planting pattern on yield of summer soybean were studied. The result indicated that variety was the primary factor on yield and agronomic characters of summer soybean, The orders of 3 .factors were variety 〉 density 〉 planting pattern. In this area, the ideal combination to gain high yield was that variety was Cangdou No. 6, density was 24 thousand plants/hm^2, row spacing was 40 cm, respectively.
