摘　　要：为解决中小型养鸡场存在的粪污影响鸡只健康和污染环境问题,考查了经2种不同可移动式发酵床垫料翻耙装置处理后的垫料发酵温度及垫料理化性质的差异,并研究了2种不同装置的应用对鸡舍内氨气浓度的影响。结果显示:在连续20 d的观察期内,经装置DP2016180处理的发酵床温度在每天的6:00、14:00、19:00均极显著(P<0.01)高于经装置DC2016180处理的发酵床温度;经2种不同垫料装置处理后的垫料总氮、总钾、总磷、pH值、C∶N均无显著性差异(P>0.05);应用装置DC2016180和DP2016180进行垫料处理的鸡舍,二者的氨气浓度在第6、8、10、12、16、18、20、22、24 h有极显著差异(P<0.01),在第14 h有显著差异(P<0.05),在第2、4 h无显著性差异(P>0.05)。研究结果可为提高养殖垫料管理装置的科学应用水平提供技术支持。In order to solve the problem that manure pollution affects the chicken health and contaminates the environment in small- and medium-scale chicken farms, the differences in fermentation temperature and physical and chemical properties of the padding treated with two movable raking devices for fermented mattress were examined. Furthermore, the effects of the application of the two devices on ammonia concentration in chicken houses were assessed. The results showed that the temperature of the fermentation bed treated by the device of DP2016180 was extremely significant (P<0.01) higher compared to that treated by the device of DC2016180 at 6:00, 14:00 and 19:00 every day during a continuous observation period of 20 days;there was no significant difference (P>0.05) in total nitrogen, total potassium, total phosphorus, pH value and C∶N between the paddings treated with the two different devices. Extremely significant difference (P<0.01) in ammonia concentration between the chicken houses treated with the two different devices was observed at 6 h, 8 h, 10 h, 12 h, 16 h, 18 h, 20 h, 22 h and 24 h after treatment, significant difference (P<0.05) was observed at 14 h after treatment, and no significant difference (P>0.05) was observed at 2 h and 4 h after treatment. Our results may provide technical support for improving the scientific application level of the padding management device.
