| 摘 要： | 笃第四纪红色粘土发育的红壤，运用超声分离技术将复合体分离，测定其不同活性有机磷和土壤磷酸酶，结果表明：红壤及其复合体有机磷的质量分数随着肥力的提高呈增大趋势；土壤有机磷主要存在于〈１μｍ的复合体中；无论是红壤还是复合体，其有机磷以中告示知性有机磷和中等稳定有机磷为主，两者之这和占有机磷总量的８０％，并且它们与土壤磷酸酶呈较好的正相关关系。

| Abstract: | Complexes in various size fractions from different fertility red soils obtained from Quaternaryred clay were separeted by ultrasonic dispersion in water. The various active organic phosphorus andphosphatase were analyzed in the paper. The results showed that the amount of organic phosphorus insoils and their complexes became larger with the increase of the fertility of red soils. The red soils andtheir complexes were dominantly involved in moderately active organic phosphorus (MAOP) and moder-ately stable organic phosphorus (MSOP), which were 80% of the total organic phosphorus. There was asignificantly positive relationship between soil phosphatase and soil complexes phosphorus. |
