| 摘 要： | １６ 年长期定位试验结果表明： 在湘南第四纪红壤中， 长期施用化肥下土壤对 Ｈ２ Ｐ Ｏ－４ 的吸附量相对较大， 化肥＋ 秸秆还田下则较小； 不同 Ｈ２ Ｐ Ｏ－４ 吸附量范围内的解吸量和解吸率则均以化肥＋ 秸秆还田较高。

| Abstract: | The results from 16 years' long-term experiment indicated that there were obvious effects occured not only in nutrient after long-term applying inorganic fertilizers and returning the crop straw into soil in Quaternary red clays in the south of Hunan province. The soil adsorption capacity of H 2PO - 4 was higher in the treatment of applying inorganic fertilizers than that of applying inorganic fertilizers with returning the crop straw into soil, but the desorption amount and desorpted rate of H 2PO - 4 by soil in different absorption capacity range were higher in the latter treatment. |
