| 摘 要： | 用发育于玄武岩和花岗岩的红壤及其水稻土作水稻盆栽试验研究红壤的磷肥有效性差异及其土壤化学特点，试验表明，花岗岩发育的红壤及其水田的磷肥有效性与Ｆｅ，Ａｌ有关，而玄武岩发育者，不仅占Ｆｅ，Ａｌ，而且还与Ｍｎ有密切关系，对土壤－植物系统中磷肥有效性与Ｆｅ，Ｍｎ元素相互作用及其机理进行了讨论。

| Abstract: | Rice pot experiment was conducted with red earths and their paddys derived from graniteand basalt to study the differences in their P fertilizer zvailability and soil chemistrycharacteristics. It was found that for the red earth and its paddy soil derived from granite.the P availability was mainiy related to Fe and Al while for those from basait the Pavai-lability was related to not only Fe and Al,but also Mn. The mechanism of P fertiliser avai-lability in red earths affected by Fe and Mn in the soil-plant system was discussd. |
