【摘要】 为研究网上铺设锯末和稻壳养殖番鸭对粪污及栏舍内空气质量的影响,试验选取14日龄公番鸭180只,随机分为2组,对照组为番鸭直接在网上进行养殖,粪污通过网眼排到地面,试验组番鸭则是在铺设锯末和稻壳后的网上进行养殖,每周对栏舍内NH₃和CO₂浓度进行测定,70日龄养殖结束后收集所有粪污进行测定。结果显示,与对照组相比,试验组可达到污水零排放,显著降低粪污的含水率（P <0.01）,显著减少粪污排放量（P <0.01）,并显著提高垫料和鸭粪混合形成的粪污总氮含量（P <0.01）及pH值（P <0.01）,提高粪污中有机质含量（P> 0.05）;与对照组相比,试验组栏舍内NH₃浓度没有显著差异,而CO₂浓度有显著提高（P <0.05）。因而,网上铺设锯末和稻壳养殖番鸭可减少粪污的排放。更多还原

【Abstract】 In order to study effects of laying sawdust and rice husk on the net to breed Muscovy ducks on the waste and air quality in the barn,180 male Muscovy ducks at 14 day old were randomly divided into two groups. Muscovy ducks in the control group were directly fed on the net,and the waste was discharged to the ground through the mesh,and Muscovy ducks in the experimental group were cultured on the net after laying sawdust and rice husk. The concentrations of NH₃ and CO₂ in the house were measured every week,and all the waste was collected after the 70 day old breeding.The results showed that,compared with the control group,the experimental group could achieve zero discharge of sewage,significantly reduce the water content of waste（ P < 0. 01）,significantly reduce the amount of waste（ P < 0. 01）,significantly increase the total nitrogen content（ P < 0. 01）and pH value（ P < 0. 01）,and increase the organic matter content（ P > 0. 05）. There was no significant difference in NH₃ concentration,but CO₂ concentration increased significantly（ P < 0. 05）.Therefore,breeding Muscovy ducks on the net which was laying sawdust and rice husk can reduce the emission of feces.更多还原
