| 为探究规模化猪场新型清粪系统猪舍内环境指标，获取有效的监测数据，并为改进新型清粪系统的舍内环境质量提供参考，本文选择规模化猪场一新型清粪系统猪舍为监测对象进行研究，对新型清粪系统猪舍内的热环境指标和有害气体浓度进行季节性监测，分析温、湿度和氨气、硫化氢浓度的季节性变化规律。监测结果表明：不同季节舍内温、湿度范围分别为14.7~31.8℃和62.7%~75.3%，全年平均值分别为（21.8±4.1）℃和69.2%±2.5%；氨气和硫化氢浓度范围分别为1.89~10.47 mg·m-3和0.59~1.39mg·m-3，全年平均值为（5.48±2.12）mg·m-3和（0.86±0.17）mg·m-3。猪舍内温、湿度和有害气体浓度有明显的季节差异，有害气体浓度冬季最高，夏季最低，全年保持在适宜范围。研究表明，猪场采用新型清粪系统可维持适宜温、湿度并有效改善舍内有害气体浓度，为生猪的生长提供优良环境。 |

| In order to explore the environmental indicators, obtain effective monitoring data, and provide a reference for improving the environmental quality of a pig house with a new manure removing system in a large-scale farm, a piggery with a new type of manure removing system was selected as the research object in this study to conduct seasonal monitoring of the thermal environment indicators and harmful gas concentration and analyze the seasonal variation in temperature, humidity, and ammonia and hydrogen sulfide concentrations in the piggery with the new manure cleaning system. The monitoring results show that temperature and humidity ranges in different seasons were 14.7~31.8℃ and 62.7%~75.3%, with annual mean of(21.8±4.1)℃ and 69.2%±2.5%, respectively. Ammonia and hydrogen sulfide concentrations ranged from 1.89 mg·m-3 to 10.47 mg·m-3 and 0.59 mg·m-3 to 1.39 mg·m-3, with annual mean of(5.48±2.12)mg·m-3 and (0.86±0.17)mg·m-3, respectively. There were also seasonal variations in temperature, humidity, and harmful gas concentration in the pig house, with the highest harmful gas concentration in winter and the lowest in summer, and kept in the appropriate range throughout the year. It seems that the new manure cleaning system can maintain the appropriate temperature and humidity and effectively reduce harmful gas concentration in the piggery, which can provide a good environment for the growth of pigs. |
