Decreasing ammonia emission from chicken manure by microbe and litter material
应用微生物与秸秆降低鸡粪氨气释放量

Some de-odorizing microbes and litter materials were combined to decrease ammonia emission from chicken manure and minimize its dangerous effect on environment. The de-odorizing microbes (F468, M1?M9) could significantly decrease ammonia emission from chicken manure and F468 was the optimal. The ability of F468 to decrease ammonia emission could not be improved significantly by mixture with other de-odorizing microbe (M1?M9), and some microbes hindered its ability, therefore the method of application of single microbe (F468) was preferred. Ammonia was not efficiently decreased by adding litter material such as wheat bran, wheat straw and cottonseed bran. Ammonia emission was abundantly decreased by mixing litter materials with F468, such as 88% (w/w) ammonia loss was retrieved within 0?5 d by adding 5% (w/w) F468 and 10% (w/w) wheat straw. In general, the application of de-odorizing microbe and straw to decrease ammonia emission from chicken manure not only minimized its dangerous effect on environment, but also represented an alternative practice of open air burning of straw.
