摘要
优化了畜禽粪便中有机碳和有机质的检测方法,利用该方法分析了北京地区16家规模化畜禽场的粪便样品。结果表明,各类畜禽粪便中的有机碳和有机质含量差异较大:有机碳含量最高值为35.15%(猪粪),最低值为15.14%(牛粪),有机质含量最高值为70.76%(鸡粪),最低值为32.58%(牛粪);畜禽粪便中有机碳和有机质的校正方程为w(有机碳)=0.5129w(有机质)-2.3377,R^2=0.9255。
A method for determination of organic carbon and organic matter in animal manure was established in this study, which was subsequently used to assess the content of organic carbon and organic matter in animal manure samples collected from 16 intensive livestock and poultry farms in Beijing. We found that the content of organic carbon and organic matter varied in manure samples from different animal species. The highest（35.15%） and lowest（15.14%） content of organic carbon were found in porcine manure sample and bovine manure sample, respectively. Whilst, the highest（70.76%） and lowest（32.58%） content of organic matter were observed in chicken manure sample and bovine manure sample, respectively. The correction equation for determination of organic carbon and organic matter in animal manure established in this study was： w（OC） = 0.5129w（OM）-2.3377, and R^2 was 0.9255.
