植物对磷的吸收,取决于土壤的磷素供应能力和植物根的特性。实验表明,植物的磷素吸收与土壤溶液中磷的浓度、土壤活性磷含量及土壤磷缓冲容量有关。根的形态,如长度、直径、表面积等,对磷素吸收有很大影响。根的这些特征也受到土壤性质的影响。土壤对磷以质流或扩散方式向根表面移动的速率起着明显作用。已结合不同的土壤和植物参数,建立 Phosphorus absorption by plants depends on the ability of the soil to supply phosphorus and plant roots. Experiments show that plant phosphorus uptake and phosphorus concentration in soil solution, soil active phosphorus content and soil phosphorus buffer capacity. Root morphology, such as length, diameter, surface area, etc., have a significant impact on phosphorus uptake. These characteristics of the root are also affected by the nature of the soil. Soil plays a significant role in the rate at which phosphorus moves toward the root surface by mass flow or diffusion. Established in combination with different soil and plant parameters
