山东菏泽定陶地区土壤元素地球化学特征
Soil geochemistry in Dingtao area of Heze,Shandong
【摘要】 对山东菏泽定陶地区进行土壤地球化学研究,利用AFS820原子荧光光度计和2100 DV电感耦合等离子体发射光谱仪,测定土壤元素的种类和含量。对区内土壤元素的含量特征进行分析,元素迁移转化规律研究及对元素的地球化学等级划分。结果表明:①研究区表层土壤中养份元素K和Ca均与植物的长势成正相关;②深层土壤元素(S、K、Fe、Ca、N、Mn、Cu、Mo等)与植物的长势相关性较小;③植物(山药)对土壤中V、Mn、Zn、Sr、Se、I、Ni元素需求较多;④Ca、N、Mn、Cu、Ni、Co、P、B、Sb、F元素的K值(深层土壤/表层土壤)较高。
【Abstract】 The soil geochemistry was studied in Dingtao area of Heze,Shandong,and the species and content of soil elements were determined by AFS820 atomic fluorescence photometer and 2100DV inductively coupled plasma emission spectrometer. The content characteristics of soil elements in the area were analyzed,element migration and transformation were studied,and the geochemical classification of elements was conducted. The results showed that: ① the nutrient elements K and Ca in surface soil were positively correlated with plant growth in the studied area; ② deep soil elements (such as S,K,Fe,Ca,N,Mn,Cu,Mo,etc) have little correlation with plant growth; ③ plants (such as yam) need more V,Mn,Zn,Sr,Se,I and Ni in soil; ④K values (deep soil/surface soil) of Ca,N,Mn,Cu,Ni,Co,P,B,Sb and F were higher.
