摘　　要：为了探明肉鸡粪便理化指标与其肥料成分含量之间的相关关系 ,采集了具有代表性的 2 0个肉鸡粪便样本 ,使用密度计和电导仪测定肉鸡粪便密度和电导率 ,用实验室常规分析方法测定其干物质、氮、磷、钾和铵态氮的含量 ,对肉鸡粪便理化指标与其主要肥料成分含量的相关关系进行了研究。研究结果表明 :肉鸡粪便密度与磷含量之间具有显著的相关关系 ,R2 =0 .844 7(P <0 .0 0 1) ;电导率与钾和铵态氮含量之间具有显著的相关关系 ,其相关系数分别为 R2 =0 .73 4(P <0 .0 0 1)和 R2 =0 .85 2 (P <0 .0 0 1)。通过测定粪便密度和电导率可快速、较准确的预测家禽粪便中氮、磷。In order to study the correlations between chemical-physical characteristics and nutrient contents in broiler manure, 20 typical fresh broiler manure samples were collected. By using specific gravity (SG) meter and electric conductivity (EC) meter, the SG and EC values in the broiler manure samples were determined. Based on lab analysis, the content of N, P, K and NH + 4-N in broiler manure were given. According to the results of regression analysis of the above data, specific gravity (SG) correlates well with P content (R 2=0.8447, P< 0.001), and electric conductivity (EC) correlates accurately with NH + 4-N and K levels (R 2=0.734, P<0.001 and R 2=0.852, P<0.001). In this case, P, NH + 4-N and K contents in broiler manure can be estimated precisely through a quick test of SG and EC values.
