云南12种豆科灌木饲料中主要磷形态分析

Study on the determination of phosphorus species in feeding Leguminosae shrubbery in Yunnan

摘要: 研究了云南12种豆科灌木饲料中磷的主要形态,经形态分离、提取并测出各形态含量.结果表明,总磷含量差异为106～330μg/g,大多数饲料所含无机磷均在24%～50%,所含有机磷为24.80%～63.9%.

Abstract: The phosphorus species in twelve feeding Leguminosae shrubbery in Yunnan was studied by sequential chemical extraction.The phosphorus extracts were determined by spectrophotometry method.Results show that the phosphorus amount is between 106-330μg/g.The distribution percentage of inorganic phosphorus is between 24.80%-63.99%.
