On the presentation of Mn-P fixation, this paper reviews the latest advances in recent 10 years and concentrates on the mechanism of phosphorus fixation in acid soils. In addition, it brakes through the classical inorganic P fractionation in to Fe-P, Al-P, O-P and Ca-Pin the traditional P classification and considers Mn-P as one of the main phosphorus fixation modes in latosols, cultivated from the parent basalt material. Furthermore, fixation of P by Fe, Al, Mn is compared, and differentiation from chemical availability and bioavailability of P discussed. Based on the above, this paper presents some alienable measures for enhancing P utilization efficiency and postulates pivotal future research directions in the field of P fixation.

本文以Mn-P的提出为出发点，论述了近10年来对酸性土壤固磷机理研究的新进展，突破了常规P素形态分级研究中分为Fe-P，Al-P，O-P和Ca-P等无机磷测定的经典分级，认为玄武岩母质砖红壤中的Mn-P是P素固定的主要形式之一，进而比较了Fe、Al、Mn对P固定作用，并从P的化学有效性与生物有效性差异等方面进行了比较全面的论述，提出了减少P素固定提高磷肥利用率的措施及今后的重点研究方向。
