| 摘 要： | 通过室内培养和盆栽试验研究了La对红壤硝化作用，磷转化作用和酚分解作用的影响，低浓度下，La对土壤的硝化作用和磷转化作用均有某些刺激作用，但随着浓度的升高产生抑制作用并不断增加，La对土壤酚分解作用表现为剧烈的抑制作用，并随着浓度的升高，抑制作用不断增强，随着培养时间的延长，La对土壤硝化作用和酚分解作用的抑制作用有降低的趋势。

| Abstract: | The effects of La on nitrification, phosphorus transformation and phenol decomposition were studied through room culture and pot culture. La has stimulative effects on soil nitrification and phosphorus transformation at low concentration but has inhibitory effect at high concentration, and the inhibition is strengthened with increasing of La concentration. La has strongly stimulative effect on soil phenol decomposition and the inhibition is strengthened with increasing of La concentration. When the incubation is prolonged, there is a tendency of decreasing in the inhibitory effects of La on soil nitrification and phenol decomposition. |
