摘　　要：本文通过对大豆公顷 4 875kg产量潜力的探讨 ,分析了大豆高产理论和公顷产量 4 875kg株型特征。指出个体、群体和环境构成了影响大豆单位面积产量的三要素。三者之间相互制约。同时 ,通过小面积 ( 1m2 )公顷产量 4 875kg的获得 ,描述了各时期叶面积指数、干物重和光合速率等参数的变化规律。指出 ,均匀─主茎型 (黑农 4 1)和均匀—并重型 (黑农 4 0 )均可获得超高产 ,说明高产株型是多模式的。The article indicated that the three elements of soybean yield per unit area are consist of individual plant, population and environment. The inter-effect coexist among them. We suggested and described the inter-effect and dynamic change of LAI, dry matter weight, photosynthetic rate and dark respiration in every growth stage for obtaining 4875kg per hm 2(1m 2). The results showed that well-proportional-main stem and seed weight type(Heinong41), and well-proportional-main stem with branching and seeds weight type(Heinong40) all could got supper output. In a word, the plant types of supper output soybean are of many patterns.
