- 摘要：以浙江沿海地区的红壤为研究对象,通过浸滤实验,研究了在酸化条件下,红壤中可溶性结合态磷的变化和它们之间的相关关系.结果显示,红壤中可溶性FeP比CaP、AlP对酸度的变化更为敏感;当红壤中可溶性磷的原始含量较高时,随酸度的增强从固相中释出的趋势更明显;在酸化过程中,红壤中不同可溶性结合态磷之间呈现出不同的相关关系,这归因于它们对酸化敏感性的差异.
- Abstract：The lateritic soils from coastal areas in Zhejiang are as an object of study. The variance of binding phosphorus in lateritic soils under acidulated condition is researched by leaching experiment. The results show that the binding FeP is more sensitive to the acidity than Ca P and Al P in lateritic soils.Then the binding phosphorus which a high original content in lateritic soils the tendency of phosphorus releasing from solid to liquid with the increase of acidity is obvious. In acidulated process, there are different correlations between various solubility phosphoruses in due to their different sensitivities to acidity.
