| 摘 要： | 牧草中磷的测定用钼锑抗比色法与氢醌亚硫酸钠法,肉中磷含量采用钼锑抗比色法与喹啉重量法测定。对牧草及肉中两种方法测定结果分别作了统计分析,结果表明它们之间均没有显著性差异(P<0.05)。因此可统一使用钼锑抗比色法测定草原生态系统土草畜样品中的磷含量。

| Abstract: | Phosphorus content was determined using Molydenum-antimony-D-iso-ascorbie-acid-colorimetry(MADAC) and Quinol-sodium-sulfite-colorimetry(QSSC) in pasture, MADAC and Quinolin-gravimetry(QG)in meat. Statistic analysis was made and no significant difference was found (P>0.05). Because of this, the above methods except MADAC are not necessary to be used in estimating the phosphorus content in samples from soil, pasture and livestock products in grassland ecology system. |
