| 摘 要： | 【目的】研究生物除臭菌对猪粪堆肥腐熟过程的影响,为利用生物除臭菌改善生猪养殖场生态环境提供参考。【方法】利用猪粪进行堆肥发酵,试验设添加生物除臭菌处理,以不添加生物除臭菌处理作对照,测定不同处理对堆肥的温度、pH、含水量和种子发芽指数(GI)的影响。【结果】添加生物除臭菌处理相比对照处理更易提高猪粪堆肥温度,提前4 d达到高温阶段;两种处理堆肥pH均保持为8.0~9.0;堆肥第30 d,添加生物除臭菌处理含水率为28%,达到腐熟标准,而对照为33%;添加生物除臭菌处理GI为53%,对照为42%。【结论】生物除臭菌对堆肥腐熟过程具有促进作用,可在生产中应用。

| Abstract: | Objective]The present study applied biological deodorization bacteria to improve ecological environment of pig farm in order to reduce its pollutions on atmosphere, water source and soil. Method]Pig manure was used for compost fermentation. The changes in compost temperature, pH, moisture content and soybean seed germination index (GI) of the two experimental treatments (with and without biological deodorization bacteria) were determined. Result]Compared to the control , the treatment with biological deodorization bacteria increased compost temperature easier and high tempera-ture phase occurred 4 days in advance. The pH variation tendency of compost of two treatments was basically the same and kept in pH 8-9. Water content of compost was 28%on the 30th day and reached decomposition standards,while water con-tent of the control was 33%. The GI of soybean seeds was 53%on the 30th day,while the control was 42%. Conclusion]Bio-logical deodorization bacteria can promote the decomposed process and can be used in production. |
