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。

Soils dominated by 2:1 clays(montmorillonite, vermiculite, illite), more frequently found in temperate zones, but also present in tropical and subtropical areas; behave different from the typical tropical red soils (Ultisols and Oxisols dominated by Fe and Al oxides and kaolinite) and from the soils developed from volcanic ash (Andisols dominated by allophane, imogolite, and humus-Al complexes) that are widely spread over the world.

我们常在温带地区发现的2：1型粘土矿物为主的土壤，也出现在热带和亚热带地区。这些土壤不同于世界范围内广泛分布的典型的热带红壤(以铁铝氧化物和高岭石为优势粘土矿物的老成土和氧化土)，也不同于由火山灰（以水铝萤石、伊利缟石和腐殖质-Al复合体为优势粘土矿物的火山灰土）发育的土壤。

With aluminum treatment, aluminum absorption of wheat seedling increased swiftly, the contents of calcium and phosphorus decreased, the efflux of potassium reduced, and Scout 66 (Al-sensitive) had a distinct change than Altas (Al-tolerant).
