Breed aquatics of livestock and poultry is an important composing part of expanded agriculture in china. Cosmically intensivismal and modern breed aquatics of livestock and poultry is the development direction of future breed aquatics of our country. Intellectualized entironment control of birdhouse is a key measure for breed aquatics,so it is get diffusely recognition.Existing domestic study of regulate birdhouse waste gas concentration is very exiguity.To resolve this problems, this thesis did the distributing orderliness of ammonia and carbon dioxide in henhouse.The contents of the study could be briefly summarized as follows:1. It introduces the infection of temperature and relative humidity for the distributing orderliness of ammonia and carbon dioxide in henhouse .At the same time, this thesis analyse the connection of distributing orderliness on ammonia carbon dioxide temperature and relative humidity in different condition of weather factor (fine day and rainy day). Research show that there are very strong correlative in them, the correlative coefficients is reach to 0.9982 and 0.998.2. Variety orderliness of ammonia and carbon dioxide in winter night henhouse is introduced.As a result of temperature and relative humidity are in better range,but ammonia and carbon dioxide concentration go beyond the standard,so ventilation must be enhanced.3. Distributing orderliness of ammonia concentration in winter henhouse of fine day and rainy day are analysed; Distributing orderliness of carbon dioxide concentration in winter henhouse of fine day and rainy day are analysed; Spatial distributing orderliness of henhouse ammonia and carbon dioxide concentration in summer fine day.The largest concentration grads of ammonia is 17.8PPm and the largest concentration grads of carbon dioxide is 930PPm.The models of distributing orderliness of henhouse ammonia and carbon dioxide concentration are constructed.4. Mechanism ventilation is a main measure for regulate ammonia concentration and carbon dioxide concentration of henhouse.The model of ammonia and carbon dioxide concentration variety with time about mechanism ventilation are constructed.The contents of the study on regulate ammonia concentration and carbon dioxide concentration and intellectualized entironment control of birdhouse are foundation work.It is important for modern breed aquatics and regulating henhouse waste gas concentration temperature and relative humidity.
