采用火焰原子吸收分光光度法测定了鸡粪中所含铜、锌、铅、镉等元素的含量。同时,为了进一步了解鸡粪对土壤特性的潜在影响,对土壤、鸡粪的其它指标做了检测,结果显示,在对有机肥料的调查中,重金属水平并不高于土壤污染所允许的限度,并且他们对土壤质量的提高发挥着作用。
Flame atomic absorption spectrophotometry was used to determine the contents of copper, zinc, lead and cadmium in chicken manure. At the same time, in order to further understand the potential impact of chicken manure on soil properties, other indicators of soil and chicken manure were tested. The results showed that in the investigation of organic fertilizers, the level of heavy metals was not higher than the limit of soil pollution, And they play a role in improving soil quality.
