虽然许多研究报道了各种形态的无机磷在土壤中转化的化学过程,但在近分子尺度下理解各种难溶性磷酸钙的结晶(固定)和溶解机制的研究相对缺乏,尤其对于发生在溶液中最早期的物理化学过程(即成核过程),和随后的晶面生长动力学过程更是知之甚少.本文借助生物磷酸钙的微观矿化机制和其他相关生物矿物的研究进展,重点综述和讨论在近分子层面上各种有机和无机影响因子对正磷酸钙在地质条件和活性的土壤根际条件下结晶和溶解动力学过程的调控,这将为认识和揭示磷在复杂土壤溶液中和在土壤固体表面上的生物地质化学行为提供可能的微观线索.
Although many studies have reported the chemical processes of various forms of inorganic phosphorus transformation in the soil, there is a relative lack of understanding of the crystallization (immobilization) and dissolution mechanisms of various insoluble calcium phosphates at a near molecular scale, especially for solutions occurring in solution In the earliest stages of physicochemical processes (ie nucleation process), and subsequent growth kinetics of the crystal plane is even less known.This paper with the help of bio-calcium phosphate mineralization mechanism and other related biological minerals research progress, focusing on And discussing the effects of various organic and inorganic influencing factors on the dynamics of crystallization and dissolution under soil rhizospheric conditions of ortho-calcium phosphate at geological level and activity at a near-molecular level, which will be useful for understanding and revealing phosphorus in complex soil solutions And biogeochemical behavior on soil solid surfaces.
