摘要： 分析结果表明,砂姜黑土中微量元素锰、锌、钼和硼的含量均低于全国平均值;有效态微量元素锌、锰、硼和钼含量普遍较低,施用微肥于砂姜黑土具有良好的增产效果。

Abstract: In the paper the total and available contents of trace elements in lime concretion fluvo-aquic soils and effect of trace element fertilizers on crop yield were dealed with. The results showed that the total contents of Mn,Zn,B and Mo were lower than the average of soils in China and the contents of available Zn,Mn,B,Mo were also low,so trace element fertilizers could remarkably raise the crop yields in lime concretion fluvo-aquic soils which the contents of available trace ele-ments were lower than the critical values.

Key words: Trace elements, Content, Trace element fertilizer, Crop yield, Lime concretion fluvo-aguic soil
