| 摘 要： | 采用培养试验的方法研究了牛粪、猪粪、麦秸 3种有机肥料对黄褐土有机磷组分含量的影响。结果表明 :施用有机肥料能明显提高土壤高活性、中活性和中稳性有机磷含量 ,特别是中活性有机磷含量 ,3种有机肥料对土壤有机磷含量的影响大小排序为牛粪 >猪粪 >麦秸。施用有机肥料后 ,土壤有机磷含量在培养的前 2 0天逐渐升高 ,其后逐渐降低 ,变化较明显的是中活性有机磷。

| Abstract: | Soil incubation was carried out to study the effects of cow dung, pig excrement and wheat straw on soil organic phosphorus fractions contents. The results showed that the organic manures increased the contents of soil labile, moderately labile, moderately resistant and high resistant organic phosphorus in soil and the organic manures influence was cow dune > pig excrement > wheat straw. The contents of soil organic phosphorus increased gradually during 0～1 day's after organic manures application, thereafter increased gradually, the change of moderately labile organic phosphorus content was obviously. |
