摘　　要：实验研究阿魏酸、对羟基苯甲酸对土壤中的氮矿化的影响，分析了麦秸和麦秸在土中腐解时产生的酚酸与土壤中氮矿化作用的相关性．结果表明，２种酸对氮矿化的影响不同．在对羟基苯甲酸存在下微生物对氮的固持作用大于在阿魏酸存在下的固持作用．土样中加入酚酸与加入麦秸相比，麦秸对土壤中氮的矿化的影响更为显著，变化趋势也不同．An ivestigation on the influence of the ferulic acid and p hydroxybenzoic acid on the nitrogen mineralization in the soil was carried out.It was showed that ferulic acid and p hydroxybenzoic acid could immobilize the nitrogen in the soil and the influence of the p hydroxybenzoic acid was stronger than that of ferulic acid.The results also showed that the soil nitrogen mineralization was much stronger influenced by straws than that of phenolic acids,and with different trends.
