| 摘 要： | 以超高产大豆品种辽豆14和普通品种辽豆11为试材,在不同磷酸二铵施用量和种植密度处理下,对其氮素积累和产量进行了比较.结果表明:施用磷酸二铵可以促进大豆茎秆、叶片、荚皮、籽粒和全株氮积累,随着种植密度的增加,植株各器官和全株氮积累量呈下降趋势.在生殖生长期,超高产品种叶柄中氮积累量均高于普通品种.随着磷酸二铵施用量和种... |

| Abstract: | The variation of matter production ability between super-high-yielding soybean cultivar and common soybean cultivar was uncertain before.The experiment was conducted as a double split-plot design with three replications.Main plots were diammonium phosphate treatments,split plots were planting density treatments and the split-split plots were cultivars.The results showed as follows:diammonium phosphate treatment could promote N accumulation in stem,leaf,pod wall,seed and the whole plant.N accumulation in eve... |
