摘　　要：研究了成都市蒲江县窗子坝土地整理区柑橘园土壤中B、Mo、Zn、Cu、Fe等微量元素的有效态含量,对各微量元素的有效态含量满足作物生长需要的状况进行评价,并讨论了有效态含量与pH值、有机质含量之间的关系。结果表明,窗子坝土地整理区柑橘园土壤有效Fe含量丰富—极丰富,有效Zn含量中等—丰富,有效Cu、有效Mo总体含量在中等以上,有效B含量极其缺乏。针对元素有效态含量的特征,提出了柑橘生产过程中应增施硼肥,并防止有效Fe、有效Cu过高而影响柑橘生长的建议。This paper has studied the available content of such trace element including B, Mo, Zn, Cu and Fe, and also discussed the its satisfaction degree for vegetation grow-up needs as well as the correlation between available content, pH value and organic matter. The results show that the content of available. It is indicated that available Fe content is abundant to extra-abundant, for Fe it＇s medi- um to abundant, for Cu and Mo, it＇ s above the average level, whereas lack of B. Based on these conclusions, suggestion for citrus planting is put forward： add enough B to the soil and to prevent excessive Fe and Cu.
