磷在植物代謝过程和能量的传递中起一定的作用,也是构成核酸、磷脂等重要物质的組成部分。植株中存在的无机磷,具有保持細胞液浓度和調节緩冲的作用。在生育期間供給大豆植株充分的磷素营养,可以加速光合磷酸化过程,促进叶片营养物质的外运,从而能增强叶片的光合能力,促进大豆营养器官的生长。磷素还可以增强大豆根部 Phosphorus in plant metabolism and energy transfer play a role, but also constitute the nucleic acid, phospholipids and other important components of the composition. The presence of inorganic phosphorus in plants, with the role of maintaining the concentration of cytosol and regulate the buffer. The supply of sufficient phosphorus nutrition to soybean plants during the growth period can accelerate the photosynthetic phosphorylation process and promote the transport of leaf nutrients so as to enhance the photosynthetic capacity of the leaves and promote the growth of vegetative organs of soybean. Phosphorus also enhances the roots of soybeans
