| 摘 要： | 采用湿润好气培养法 ,研究稻草等有机物料腐解过程中酚酸类化合物的动态变化。结果表明 ,稻草、锯木屑、猪粪均含有对羟基苯甲酸、香豆酸、阿魏酸等酚酸化合物。稻草、猪粪中香豆酸含量最高 ,阿魏酸次之 ;木屑中对羟基苯甲酸含量最高 ,香豆酸次之。稻草、猪粪在腐解过程中生成酚酸化合物主要是香豆酸和阿魏酸 ,木屑主要是对羟基苯甲酸和香豆酸 ;三种有机物料中酚酸化合物总量表现为稻草 >猪粪 >木屑 ,在腐解 2 0～ 30天时酚酸量为最高 ,40～ 5 0天时基本稳定 ,酚酸量为最少

| Abstract: | Variation of phenolic acids during decomposition of some organic materials was studied by means of moist and aerobic cultivation.The results show that rice straw,pig feces and sawdust contain some kinds of phenolic acids such as p-hydroxybenzoic acid,p-coumaric acid and frulic acid.The contents of p-coumaric acid in rice straw and pig feces are the highest,and followed by that of frulic acid.The content of p-hydroxybenzoic acid in sawdust is the highest,followed by that of p-coumaric acid.During decomposition,the main kinds of phenolic acid in rice straw and pig faces are p-coumaric and frulic acids while in sawdust p-hydroxybenzoic and p-coumaric acids.The total phenolic acid contents are in a decreasing order,rice straw,pig feces,and sawdust.The total phenolic acid contained in the three organic materials reached the maximum after 20~30 days of decomposition,and reached a stable and minimum state after 40~50 days. |
