对黄淮地区３６个夏大豆品种及品系的产量构成因素、生育特性、开花结荚动态及产量的空间分布进行了研究．单株产量与粒数、荚数、株高、主茎节数呈显著或极显著正相关，与结荚高度呈极显著负相关．株高、主茎节数、荚数、粒数对产量有较大的正向直接作用．结荚高度对产量有较大的负向直接作用．早花型品种产量水平较高，高产品种均为亚有限结荚习性，其产量空间分布为垂直分布均匀型和水平分布主茎型．
The yield components, growth characteristics, flowering pod dynamics and the spatial distribution of yield of 36 summer soybean cultivars and cultivars in Huanghuai area were studied. The yield per plant was significantly or very significantly positively correlated with the number of pods, pods, plant height and main stems, and was significantly and negatively correlated with the pod height. Plant height, the number of main stems, pod number, grain yield on the larger positive direct effect. Pod height has a greater negative impact on yield. Early flowering varieties yield higher levels of high-yielding varieties are sub-limited pod habit, and its spatial distribution of vertical distribution and horizontal distribution of the main stem type.
