摘要: 研究山西省原平市玉米种植区土壤微量元素含量情况及其与有机质和pH之间的关系,为当地玉米高产优质生产提供理论依据。根据研究区域玉米种植区划,采集了0~20 cm耕层土壤样品,测定土壤pH、有机质以及微量元素铜、锌、镍、铁、锰、硒和钙的含量,利用Pearson相关分析法和一元线性回归方法对土壤微量元素全量与有机质和pH的关系进行分析。结果表明,原平市土壤有机质含量为4.10~53.98 g/kg,平均值为17.29 g/kg;pH为7.50~8.66,平均值为8.08,表明原平市土壤有机质含量处于中等偏低水平。土壤中的微量元素铜、锌、镍、铁、锰、硒和钙含量的平均值分别为20.61 mg/kg、68.47 mg/kg、33.30 mg/kg、2.92%、578.13 mg/kg、0.28 mg/kg和4.07%,其中,锌、镍、锰、硒的平均值高于山西省背景值,铜、铁、钙的平均值低于山西省对应元素土壤背景值。铜、锌、硒含量与pH呈极显著负相关关系(P<0.01),铁含量与pH呈显著负相关关系(P<0.05),钙含量与pH呈极显著正相关关系(P<0.01);锌含量与有机质呈极显著正相关关系(P<0.01),铜、硒含量与有机质呈显著正相关关系(P<0.05),钙含量则与有机质呈极显著负相关关系(P<0.01)。

Abstract: In order to provide theoretical basis for high yield and high quality maize production in the corn belt of Yuanping city, Shanxi province, the concentrations of soil trace elements and the relationship between organic matter, pH and soil trace elements content was studied. According to the study area in corn planting regionalization, the surface soil samples(0~20 cm)were collected to determine the contents of soil pH, organic matter and trace elements Cu, Zn, Ni, Fe, Mn, Se and Ca. And the relationship between total concentrations of soil trace elements with organic matter and pH were analyzed by using Pearson correlation analysis and one-dimensional linear regression. The results showed that the concentration of organic matter was 4.10 to 53.98 g/kg, the average value of organic matter was 17.29 mg/kg;The pH was 7.50 to 8.66, the average value of pH was 8.08, indicating that the content of soil organic matter in the study area is at a medium and low level. The average contents of Cu,Zn,Ni, Fe, Mn, Se and Ca were 20.61 mg/kg, 68.47 mg/kg, 33.30 mg/kg, 2.92%, 578.13 mg/kg, 0.28 mg/kg and 4.07%, respectively. The average values of the total Zn, Ni, Mn and Se were higher than the background value in Shanxi province. while the average values of the total Cu, Fe and Ca were lower than the back ground value in Shanxi province. The contents of Cu, Zn and Se were negatively correlated with pH(P<0.01), the contents of Fe were negatively correlated with pH(P<0.05), and the contents of Ca were positively correlated with pH(P<0.01); The contents of Zn were positively correlated with organic mater(P<0.01), the contents of Cu and Se were positively correlated with organic mater(P<0.05), and the contents of Ca were negatively correlated with organic mater(P<0.01).
