| 摘 要： | 广东省赤红壤垦种芒果后，土壤的矿质营养状况基本上改善不大，地力产量仍然很低。应用土壤肥力系统研究法诊断土壤营养元素的结果表明，其缺素效应排序为：Ｎ＞Ｐ、Ｃａ＞Ｋ＞Ｍｇ；土壤Ｆｅ和Ｃｕ无缺素反应，而Ｓ、Ｂ、Ｍｎ、Ｍｏ和Ｚｎ有个别土样显示缺素效应，对这些元素丰缺的确切结论，有待进一步研究。

| Abstract: | Mineral nutrients status of soils are not significantly improved and fertility is still low after cropping mango in latored soils in Guangdong. The order of nutrientdeficiency ranged by using survey procedure is N>P,Ca>K>Mg. Fe and Cu are Onabundant level, bElt S, B, Mn, Mo and Zn show deficient in a minority of soils. Exactconclussion about the nutrients abundance or deficiency needs further study. |
