| 中文摘要: |
| 以微生物异位发酵床填料为研究对象，研究了不同原料填料对生猪养殖废弃物的处理效果，分析了在相同条件下玉米秸秆填料与稻壳和椰壳粉混合物填料在温度、pH、含水量、微生物数量和营养成分变化上的差异。结果表明，稻壳和椰壳粉混合物更容易控制温度的变化，发酵床温度保持在25~54℃，并且其pH变化范围较小，为7.6~8.9，更接近好氧发酵的最适pH值范围。稻壳和椰壳粉混合物填料处理含水量稍低于玉米秸秆填料处理，维持在44%~64%之间。试验结束时，两个处理发酵床填料的pH、TN、TP、TK和有机质等指标均符合国家有机肥标准。 |

| In this study, the microbial ectopic fermentation bed filler was taken as the research object to study the effects of different raw materials on the treatment effect of pig breeding wastes. Under the same conditions, the effects of corn stalk filler and the mixture of rice husk and coconut shell powder on temperature, pH, moisture content, microbial population and nutrient content were analyzed. The results showed that the mixture of rice hulls and coconut husk was easier to control temperature changes, maintaining at 25~54℃. At the same time, its pH change was small, at 7.6~8.9, closer to the optimum pH for aerobic fermentation range. The moisture content of the rice husk and coconut husk mixture filler was slightly lower than that of the corn stalk filler, maintaining between 44%~64%. At the end of the experiment, all the indexes of the two kinds of fermentation bed accorded with the national standard of organic fertilizer. |
