Livestock and poultry breeding industry is one of the main industry of rural economy. The rapid development brings environmental pollution problems and now it is the main restricting factor in the construction of new countryside. This paper analyzed the ammonia emission ways under the returning patternand summarized some ammonia reduction measures. Combined with the development of livestock and poultry breeding industry and farmland utilization, this paper summarized that in order to reduce ammonia emission under livestock manure returning pattern, we should feed animals with low protein feed to reduce the generation of N. After solid － liquid separation of livestock waste, store the manure with airtight coverage to reduce the volatilization of ammonia. In the spring, deep tillage with fertilizer application on the land to reduce ammonia emissions. If surface fertilization, the land soil should be turned or ploughed immediately.
