植物主要吸收正磷酸盐形态（H₂PO₄⁻）的磷元素，因此土壤中速效磷含量是评价土壤供磷能力的重要指标，对合理施肥具有直接的指导意义。 本试剂盒采用钼锑抗显色法测定土壤速效磷含量。其原理为：土壤中的速效磷在酸性条件下与钼酸铵生成磷钼杂多酸，该杂多酸被钼锑抗显色剂中的抗坏血酸还原，生成蓝色的磷钼蓝络合物，该产物在700 nm处具有特征吸收峰。在既定线性范围内，700 nm处反应液的吸光度与土壤中速效磷含量呈正比，通过标准曲线即可定量计算样品中的速效磷含量。
Plants predominantly absorb phosphorus in the orthophosphate form, specifically as dihydrogen phosphate (H₂PO₄⁻). Consequently, the content of available phosphorus in soil serves as a critical indicator for assessing soil phosphorus-supplying capacity and holds direct guiding significance for rational fertilization. This kit employs the molybdenum-antimony ascorbic acid colorimetric method to determine the content of available phosphorus in soil. The underlying principle is as follows: under acidic conditions, available phosphorus in the soil reacts with ammonium molybdate to form a phosphomolybdic heteropoly acid complex. This complex is subsequently reduced by the ascorbic acid present in the molybdenum-antimony colorimetric reagent, yielding a blue phosphomolybdenum blue complex, which exhibits a characteristic absorption peak at 700 nm. Within the established linear range, the absorbance of the reaction solution at 700 nm is directly proportional to the available phosphorus content in the soil, thereby enabling quantitative determination of the available phosphorus content in samples via a standard curve.
