Methane emissions during storage of different treatments from cattle manure in Tianjin.

摘要: Many studies on methane emissions from animal manure have revealed that is a major source of to the atmosphere can negative consequences for people, animals and environment. In general, release be influenced by type feed taken animals, temperature, characteristics so on. This study aimed at quantifying comparing dairy with different piling treatments. Four treatments were designed including height 30, 45, 60 cm adding 6 every day until was cm. Static chamber method gas chromatography adopted measure April June in 2009. Methane emission rates all four low first week then increased sharply reaching peak values. Subsequently, decreased fluctuated within steady range till end experiment. Wilcoxon nonparametric tests analysis indicated rate greatly manner. There no significant relationships between temperatures ambience heap. However, regression showed quadratic equations found temperature barrels.
