采集耕地土壤198份样品，分析土壤有机质、 pH 和4种微量元素含量，并进行了相关性分析。结果表明：有机质含量较为丰富，全县平均含量达27.66 g/kg，各镇之间的差异较大；全县土壤呈酸性或强酸性反应， pH 平均值为5.10；土壤有效铜含量符合正态分布，土壤有效铁和锰稍缺乏，铜和锌较丰富；有机质与锰、铜和锌呈正相关，与锰相关关系达极显著水平； pH 同4种土壤微量元素均表现为正相关关系，与铁的相关性达到极显著水平。近期在进行农业生产时，应注重微量元素肥料的施用，避免缺素症状的发生，注意调节土壤酸碱度。

The relationship between soil trace elements and basic properties and content of Fe, Mn, Cu, Zn from 198 cultivated soil samples in Ding'an county was analyzed. Results showed that organic matter content was rich, the average content of up to 27.66 g/kg, the whole cultivated soil of this county was acidic, the average value of pH is 5.10; the available copper content in soil conform to normal distribution, soil available iron and manganese were slightly lacking, but copper and zinc were rich. There is a positive correlation between the soil organic matter and manganese, copper, zinc, and it was complicated by manganese. The correlation is positive between soil pH with four kinds of trace elements, but complicated to iron. Recently in agricultural production, part of the crop may be occur copper and zinc deficiency symptoms, should pay attention to the trace element fertilizer, at the same time, pay attention to adjust soil pH.
