低磷胁迫对香樟土壤酶活性的影响

摘要

For different soil phosphorus stress camphor acid phosphatase, catalase, urease activity were determined. Resuits showed that： phosphorus deficiency stress, camphor soil acid phosphatase activity than normal for the case of phosphorus significantly increased, and with the severity of stress, acid phosphatase activity increased significantly; camphor soil catalase, urease activity is than normal for phosphorus decreased significantly, negatively correlated with the degree of coercion.%对不同磷素胁迫下香樟土壤酸性磷酸酶、过氧化氢酶、脲酶活性进行测定。结果表明：缺磷胁迫下,香樟土壤酸性磷酸酶活性较正常供磷情况下明显增强,且随着胁迫程度的加重,酸性磷酸酶活性显著上升;香樟土壤过氧化氢酶、脲酶活性则较正常供磷明显下降,与胁迫程度呈负相关。
