| 中文摘要: |
| 为研究不同四环素类抗生素对畜禽粪污堆肥化学性质及酶学指标的影响，本试验共设置3个处理，即CK （不添加抗生素，纯羊粪）、TC（添加含10 mg·kg-1四环素的羊粪）和OC（添加含10 mg·kg-1土霉素的羊粪），并将不同处理的羊厩肥进行好氧堆肥处理（使用玉米秸秆调节C/N约为30）。结果表明： TC和OC处理堆体高温期持续时间缩短，与CK相比，TC处理堆体总积温显著降低49.3℃（P<0.05）。抗生素的添加使堆体pH、电导率与有机质分解速率受到一定程度影响。TC与OC处理使堆体过氧化氢酶活性显著降低0.24 mg·g-1·min-1和0.13 mg·g-1·min-1，脲酶活性显著增加17.38 mg·g-1·d-1和20.94 mg·g-1·d-1。研究表明，四环素类抗生素改变了堆肥过程中的化学性质和酶学指标，且不同种类抗生素影响的程度有差异，因此在堆肥发酵过程中要充分考虑这种影响，合理控制发酵条件，保证堆肥发酵的腐熟度。 |

| Aerobic composting is the principal technique to ensure the resource and safety of livestock and poultry manure. Nevertheless, the residual antibiotics in the manure can affect the composting process as resistant drugs. In this study, the effects of different tetracycline antibiotics on the chemical properties and enzymatic indexes during composting were analyzed, in order to establish theoretical basis and technical resource for the regulation of the aerobic composting process of livestock and poultry manure. Three treatments were considered for the test as follows： CK（sheep manure without antibiotics）, TC（sheep manure with tetracycline 10 mg·kg-1）, and OC（sheep manure with oxytetracycline 10 mg·kg-1）. The different treatments of sheep manure were subjected to aerobic composting（C / N was adjusted to approximately 30 / 1 using corn straw）. The results show that the high temperature period of TC and OC treatments were decreased. Compared with CK, the total accumulated temperature of TC treatment was significantly reduced by 49.3 ℃（P<0.05）. The addition of antibiotics slightly affected the potential of hydrogen, electrical conductivity and organic matter decomposition rate. Furthermore, TC and OC treatments significantly decreased and increased catalase and urease activities by 0.24 mg·g-1·min-1 and 0.13 mg·g-1·min-1, and by 17.38 mg·g-1·d-1 and 20.94 mg·g-1·d-1, respectively. From the above results, one can infer that tetracycline antibiotics alter the chemical properties and enzymatic indexes in the composting process, and the influence of different kinds of antibiotics varies. Thus, this effect should be fully considered in the composting process, and the conditions of fermentation should be highly considered to ensure complete decomposition. |
