| 摘 要： | 为探究物料覆盖对堆放存储的牛粪氨气(NH_3)和二氧化碳(CO_2)排放的影响,本研究利用氨浓度在线检测(Innova1412i)和动态箱技术,测定了酸性有机物料醋糟覆盖(覆盖厚度为0.5、1.0 cm和2.0 cm)下牛粪堆存过程中NH_3和CO_2的排放通量。结果表明,与未覆盖醋糟的对照组相比,醋糟覆盖厚度超过1 cm时可显著降低牛粪NH_3和CO_2排放(P0.05);模拟降雨去除醋糟酸性成分(洗涤醋糟)对醋糟的氨减排效果影响较小,覆盖洗涤醋糟仍达到了81.34%的氨减排率(P0.05),而添加醋糟冲洗液对牛粪NH_3和CO_2排放没有显著影响;当覆盖时段从2周延长到3周时,醋糟覆盖的氨减排率从35.22%～84.97%降低至15.58%～60.25%;醋糟覆盖还可以有效降低牛粪的C/N和提高N/P。综上,有机物料醋糟是兼具覆盖、酸化等作用的一类控氨材料,对于堆放存储的牛粪具有控氨、保氮和提质效果,但其氨减排率受养殖场粪尿储存和覆盖技术的实施时段的影响较大。

| Abstract: | An experiment was carried out to explore the effects of covering on ammonia (NH3)and carbon dioxide (CO2)emissions from stored cattle manure. NH3 and CO2 emissions from stored cattle manure covered by vinegar residues (cover thicknesses of 0.5, 1.0 cm, and 2.0 cm)were measured, using an online measurement system (Innova1412i)and a dynamic chamber technique. The results showed that the vinegar residue covering with thicknesses over 1 cm significantly reduced the NH3 and CO2 emissions from cattle manure, in comparison with the uncovered control (P<0.05). The removal of acid components from the vinegar residue with simulated rainfall (washed vinegar residue)had little effect on its ammonia reduction effect, as covering by washed vinegar residues still achieving an ammonia reduction rate of 81.34% (P<0.05), while mixing with the vinegar residues washing solution had little effect on the NH3 and CO2 emissions. When the covering period was extended from 2 weeks to 3 weeks, the ammonia reduction rates declined from 35.22%~84.97% to 15.58%~60.25%. In addition, the vinegar residue covering also effectively reduced the manure C/N and increased the N/P. In summary, the acidic organic material vinegar residue has been demonstrated to be a useful material for ammonia control, nitrogen retention, and quality upgrading for cattle manure in storage, although the ammonia reduction rate is affected by the implementation duration, and is also influenced by manure storage and covering techniques. |
