摘要
以３种不同基因型大豆品种为试材，研究大豆根瘤形成始期（二片复叶Ｖ２）和大豆生殖生长期间施用氮肥，对大豆生长、结瘤及产量的影响。试验结果表明，大豆营养生长阶段的最佳追肥时间为根瘤形成始期；而大豆生殖生长期间的最佳追肥时间为大豆开花期。
The effects of nitrogen application at the beginning of nodule formation (two trifoliolates, V 2) and the stage of reproductive growth on growth, nodule formation and yield of soybean were studied with three different genotypes. The result showed that the optmum timing of nitrogen application in vegetative period was beginning of nodule formation and that in reproductive period was blooming stage.
