中文摘要: 为了研究覆盖对不同堆积高度肉牛固体粪便温室气体(N_2O、CH_4和 CO_2)排放量的影响,试验采用静态箱的方法研究了20和40 cm堆积高度时覆盖或者不覆盖情况下肉牛粪便温室气体的排放量。结果表明,堆积40 cm的牛粪CH_4的累积排放量显著高于20 cm处理,而N_2O和CO_2累积排放量显著降低。覆盖显著增加了牛粪N_2O的排放量和40 cm高度牛粪的CH_4排放量,降低了40 cm高度牛粪CO_2的排放量,而对20 cm高度牛粪CH_4和CO_2排放无显著影响。根据CH_4和N_2O在100 a 尺度上相对CO_2的全球增温潜势计算出综合温室效应,无覆盖处理的20和40 cm牛粪的综合温室效应分别为(101.076.28)和(94.673.29)g/kg,覆盖处理的20和40 cm牛粪的综合温室效应分别为(104.206.78)和(103.433.21)g/kg,堆积高度为40 cm且无覆盖的综合温室效应最小。
英文摘要: The greenhouse gases such as methane (CH_4), nitrous oxide (N_2O), and carbon dioxide (CO_2) have increased in atmospheric concentration since 1 750, attracting more and more attention regarding climate change. Agriculture activities contribute to the increase of greenhouse gas concentration in the atmosphere, resulting in a higher global warming potential, which is estimated to contribute about 47%-58% of the total anthropogenic emissions of CH_4 and N_2O, respectively. Storage of animal manure is reported to be a significant agricultural source of methane and nitrous oxide. Generally, greenhouse gas emissions from animal manure can be influenced by storage stacking configuration and covering during storage. However, there are large uncertainties in this estimation. In order to quantify N_2O, CH_4, and CO_2 emissions from covered beef cattle solid manure compared with uncovered manure stored at different stack heights during storage, four treatments were designed including a stack height of 20 cm without covering (H20), a tack height of 40 cm without covering (H40), a stack height of 20 cm with a 2 cm sawdust covering (H20C), and a stack height of 40 cm with a 2 cm sawdust covering (H40C), and the treatments were replicated three times. Thus, twelve polyvinylchloride cylindrical (30 cm in diameter and 90 cm in height) static vessels were designed and built to measure greenhouse gas emissions in the laboratory experiment. The stacking process commenced on May 29, 2014, and was measured for 49 days. The results showed that manure stack height significantly affected GHG emissions from beef cattle solid manure for both manure with covering and without covering. Compared with the lower stack height (20 cm), the higher stack height (40 cm) increased 40.91% and 61.29% CH_4 cumulative emissions per unit of manure weight for covered manure and uncovered manure, respectively, But it decreased by 38.06% and 35.21% N_2O cumulative emissions, and 43.68% and 55.12% CO_2 cumulative emissions per kg of manure weight. N_2O cumulative emission from beef cattle solid manure increased significantly by using cover material regardless of stack heights, 33.87 vs. 42.32 mg/kg for 20 cm stack height and 20.98 vs. 27.42 mg/kg for 40 cm stack height, respectively. CH_4 cumulative emissions from covered beef cattle solid manure (3.00 g/kg) was significantly higher than that from the uncovered treatment (2.48 g/kg) for the 40 cm stacks, but CO_2 cumulative emissions from covered beef cattle solid manure was significantly lower for the 40 cm stacks, 26.42 vs. 20.20 g/kg. There were no significant difference for CH_4 (1.76 vs. 1.86 mg/kg) and CO_2 (46.91 vs. 45.01 g/kg) cumulative emissions from covered beef cattle solid manure compared with uncovered for 20 cm stacks. Both CH_4 and CO_2 are the predominant greenhouse gas emitted from solid cattle manure storage facilities. On the basis of a 100 year global warming potential for CH_4 and N_2O, cumulative greenhouse gas emissions were (101.076.28) and (94.673.29) g/kg of manure weight for the 20 and 40 cm stacks without cover, and were (104.206.78) and (103.433.21) g/kg of manure weight for 20 and 40 cm stack height with cover, respectively. The results suggested that beef cattle solid manure of a 40 cm stack height without covering produced the least greenhouse gas emissions.
