摘  要：
为探明奶牛粪颗粒粒径及其有机碳和养分分布特征,以新鲜的泌乳奶牛粪为研究对象,通过分级筛分方法得到了粒径分别为≤0.10、0.11～0.20、0.21～0.50、0.51～1.00、1.01～2.00和>2.00 mm的颗粒样品,并对其质量、总有机碳(TOC)、总氮(TN)、总磷(TP)和总钾(TK)含量及其所占比例,以及C/N分布进行分析。结果表明,不同粒径颗粒所占比例依次为≤0.10 mm颗粒28.0%、1.01～2.00 mm颗粒25.3%、0.51～1.00 mm颗粒24.2%、>2.00 mm颗粒11.5%、0.21～0.50 mm颗粒7.5%、0.11～0.20 mm颗粒3.5%。TOC主要存在于较大颗粒(粒径>0.50 mm)中,约占总量的70%;而TN、TP和TK主要存在于较小颗粒(粒径≤0.1 mm)中,占各自总量的44.4%、50.1%和67.3%。固液分离后固体的C/N较高。

摘  要：
In the present study, fresh cow manure was used to investigate the distribution characteristics of particle size, organic carbon and nutrients in cow manure. Samples with particle sizes of ≤0.10 mm, 0.11-0.20 mm, 0.21-0.50 mm, 0.51-1.00 mm, 1.01-2.00 mm and >2.00 mm were obtained by classification screening method, and their weight, total organic carbon(TOC), total nitrogen(TN), total phosphorus(TP) and total potassium(TK) contents and their proportion, as well as C/N were determined. The results showed that the proportions of different particle sizes followed the order of(≤0.10 mm, 28.0%)>(1.00-2.00 mm, 25.3%)>(0.51-1.00 mm, 24.2%)>(>2.00 mm, 11.5%) >(0.21-0.50 mm, 7.5%) >(0.10-0.20 mm, 3.5%). TOC was mainly present in larger particles(particle size of > 0.50 mm), accounting for about 70% of the total TOC of fresh cow manure. TN, TP and TK mainly existed in smaller particles(particle size of ≤0.1 mm), accounted for 44.4%, 50.1% and 67.3% of the total TN, TP and TK, respectively. The C/N of solid fraction after solid-liquid separation was higher.
