本试验以三种不同结荚习性的大豆品种为试材，按不同比例三成份混种，采用随机区组设计，针对三种结荚习性成份的混合群体混合种对子粒产量及外观品质的影响进行了理论上的研究，结果表明，混合群体产量基本上均较高产成份减产，但混合群体的产量均有超补偿作用即混合群体的实际产量较理论产量增产，而于粒外观品质表现较差，最突出的是混合群体的褐斑粒率、虫食粒率增高，完全粒率降低。
In this experiment, we used three kinds of soybean cultivars with different pod properties as test materials, and mixed them with different proportions of three components to design a randomized block design. The effects of mixed population of three pod habitats on grain yield and appearance quality The results show that the yield of the mixed population is basically lower than that of the high yield component, but the yield of the mixed population is overcompensated. That is, the actual yield of the mixed population increases more than the theoretical yield, but the grain appearance quality is poor , The most prominent is the mixed population of brown spot rate, worm rate increased, the complete grain rate decreased.
