摘要
为了分析不同养殖模式的奶牛废弃物中磷含量的差异,选取散户养殖、养殖小区、规模养殖三种养殖模式的奶牛废弃物作为试验的样本,用钼黄比色法测定三种养殖模式的奶牛废弃物中磷的含量。结果表明:三种养殖模式的奶牛废弃物中磷含量有一定的差异,但差异不显著(P>0.05)。
In order to analyze the difference of the phosphorus content, cow waste with three kind of breeding patterns, free-range, district culture, large-scale breeding was selected as test samples, phosphorus was determined with vanadium molybdate yellow colorimetry. The experimental result showed that dairy waste phosphorus content with three breeding pattern had some differences, but the difference was not significant （P 〉0.05）.
