| 为构建精确的畜禽养殖氨(NH3)排放清单,并揭示不同畜禽类型的氨排放季节性特征,本研究以黄淮海平原南部的某集约化奶牛舍、笼养蛋鸡养殖舍和规模化育肥猪养殖舍为研究对象,采用抽气法,对春、夏、秋、冬 4个季节以及育肥猪全生育期的NH3排放通量特征进行了系统分析。结果表明:奶牛单位 NH3排放速率最高,蛋鸡单位 NH3排放速率秋季最高为 78.45 mg·d-1·羽-1,育肥猪单位NH3排放速率在猪体质量110 kg时最高为684.61 mg·d-1·头-1。蛋鸡养殖舍除冬季外,单位排放速率随季节变化呈上升趋势,而奶牛单位排放速率冬季最低为39.39 g·d-1·头-1,其次分别是春季、夏季、秋季。蛋鸡养殖舍出风口外排NH3浓度及NH3排放通量变化昼夜变化明显,秋季整体外排NH3浓度及NH3排放通量最高,分别为1.67~2.58 mg·m-3和34.6~88.84 g·h-1。奶牛场春、夏、秋三个季节NH3浓度在夜晚21:00达到最大值,而冬季在凌晨3:00,其中春季和秋季,夏季和冬季的NH3排放通量趋势相较一致,秋季 NH3浓度整体最高,在 0.37~1.09 mg·m-3之间波动。全生育期育肥猪随着体质量的增加,出风口外排 NH3浓度及NH3排放通量越来越高,且在体质量70 kg(6.23 mg·m-3)和110 kg(11.10 mg·m-3)时昼夜变化明显,而在体质量30 kg时,NH3浓度日变化呈下降趋势。三类养殖场舍内的NH3浓度变化与清粪频率密切相关:清粪完成后NH3浓度最低,随后随着禽舍内粪尿累积逐渐升高,直至下一次清粪后再次下降,这表明优化清粪过程是减少养殖舍NH3浓度的关键措施。 |

| In order to construct an accurate ammonia emission inventory for livestock and poultry farming and to reveal the seasonal characteristics of ammonia emissions from different types of livestock and poultry, this study selected an intensive dairy barn, a caged layer house, and a large-scale fattening pig barn in the southern Huang-Huai-Hai Plain as research subjects. Using the air extraction method, a systematic analysis was conducted on the characteristics of ammonia emission fluxes during the four seasons of spring, summer, autumn, and winter, as well as throughout the entire growth period of fattening pigs. The results showed that dairy cows had the highest NH 3 emission rate, hens had the highest NH3 emission rate per unit in the fall at 78.45 mg·d-1·feather-1, and fattening pigs had the highest NH3 emission rate per unit at a pig weight of 110 kg at 684.61 mg · d-1 · head-1. Unlike egg farms, which showed an increasing trend in unit emission rates following seasonal changes except in winter, dairy unit emission rates were lowest in winter at 39.39 g·d-1·head-1, followed by spring, summer, and fall, respectively. The changes in the external NH3 concentration and NH3 emission flux at the outlet of the laying hen farm varied significantly during day and night, and the overall external NH3 concentration and NH3 emission flux were the highest in the fall, ranging from 1.67 mg·m-3 to 2.58 mg·m-3 and 34.6 g·h-1 to 88.84 g·h-1, respectively. Dairy farm NH3 concentrations reached a maximum at 21:00 p.m. during the spring, summer, and fall seasons and at 3:00 a.m. during the winter, with relatively consistent trends in NH3 emission fluxes in the spring and fall, and summer and winter, with the highest overall NH3 concentrations in the fall, fluctuating between 0.37 mg·m-3 and 1.09 mg·m-3. The NH3 concentrations and NH3 emission fluxes out of the air outlets of full-life fattening pigs increased with the increase of pig weights and varied significantly during the day and night at pig weights of 70 kg(6.23 mg·m-3)and 110 kg(11.10 mg·m-3), whereas the daily variations of the NH3 concentrations showed a decreasing trend at pig weights of 30 kg. Changes in NH3 concentrations on the three types of farms were closely related to the frequency of manure removal:NH3 concentrations were lowest after the completion of manure removal, then gradually increased with the accumulation of feces and urine in the poultry house until they decreased again after the next manure removal. This suggests that optimizing the manure removal process is a key measure for reducing NH3 concentrations on farms. |
