| 摘 要： | 根据东北黑土地1：250000土地质量地球化学调查数据，对黑龙江省讷河市土壤中微量元素B、Cu、Mo、Fe、Mn、Zn元素全量和有效态含量分布特征进行了分析研究.结果显示：①土壤表层Mn元素含量丰富，Fe、Mo元素含量较丰富，B、Cu、Zn元素含量较缺乏；②土壤表层微量元素Cu、Fe、Mn、Zn有效态含量丰富，B有效态含量中等，Mo有效态含量缺乏；③黑土剖面中微量元素淋溶淀积程度明显，表现为以淋溶层较低，表层和淀积层较高，而草甸土淋溶淀积不明显.依据土壤中微量元素全量和有效态含量分布特点，应选择施用微量元素肥料，促进农业可持续发展.

| Abstract: | The total and available contents of trace elements such as B, Cu, Mo, Fe, Mn and Zn in the soil of Nehe City, Heilongjiang Province, are analyzed and studied based on the 1:250 000 scale geochemical survey data of the quality of black land in Northeast China. The results indicate that the surface soil is characterized by rich Mn, abundant Fe and Mo, and deficient B, Cu and Zn. In terms of available content in surface soil, Cu, Fe, Mn and Zn are abundant, B medium and Mo deficient. The leaching and deposition degree of trace elements in black soil profile is obvious, which is low in the leaching layer and high in the surface and deposition layer, but not evident in meadow soil. According to the distribution characteristics of total and available trace element contents in soil, the trace element fertilizer should be chosen to promote sustainable development of agriculture. |
