摘 要 ：本文根据1976～1980年试验资料,论述了大豆亩产400斤左右的产量结构与产量关系。当大豆亩产超过400斤时,产量因子间是个互相制约的关系,虽平方米结荚数愈多对提高单产有良好作用,但粒荚比低、百粒重小,也会直接影响产量。百粒重为24克,亩产却达454斤。大豆亩产400斤的叶面积指数变化规律,出现的高峰是在鼓粒初期,而且以5～6较

Abstract:The relationship between soybean yield and its component factorswas discussed in this paper.An interaction was shown among the com-ponent factors.Generally,soybean yield per unit area was found toincrease with the number of pods per unit area.However,small numberof soybean seeds obtained from a per
