【摘要】 对山东省优质稻生产基地鱼台包括pH、水分、有机碳及N、P、F、V、Zn、Co、Mo、Mn、Se、B、Cr、Cd、Cu、Pb、Sb、Hg、As等在内的28种地球化学元素的含量及分布特征进行研究。研究结果表明,鱼台优质稻产区土壤中N、P、K、B、Mo、Mn、Se、Fe等有益元素富集,但As、Cd、Hg、Pb等重金属元素也有明显富集趋势。鱼台地区潮土与淹育水稻土的28种地球化学元素t-检验结果显示,As,B,Co,Cr,F,Mn,V,S,Al2O3,TFe2O3,MgO,CaO含量明显高于潮土,但是SiO2和Na2O的含量却明显低于潮土。淹育水稻土C(org)、水分含量也明显高于潮土。淹育水稻土有酸化现象。更多还原

【Abstract】 In this study,geochemical elements were investigated in the Yutai high quality rice base,which is one of the typical agricultural products bases in Shandong Province,China.The soil geochemistry was investigated through 28 chemical elements,such as pH,C(org),As,B,Cd,Co,Cr,Cu,F,Hg,Mn,Mo,Ni,P,Pb,V,Zn,Se,N,S,SiO2,Al2O3,Fe2O3,MgO,CaO,Na2O and K2O.The study of soil geochemical showed that the useful elements of N,P,K,B,Mo,Mn,Se,and Fe were enriched in the Yutai high quality rice base soil.However,some heavy and toxic elements,such as As,Cd,Hg,and Pb were obviously enriched in the surface soil.The contents of As,B,Co,Cr,F,Mn,V,S,Al2O3,TFe2O3,MgO,and CaO in the submerged paddy soil(SPS) were obviously greater than in the fluvo-aquic soil(FAS),but SiO2 and Na2O were obviously lower in the FAS.The contents of C(org) and moisture in the SPS were obviously higher than in the FAS.The results showed that the SPS was apt to be acidified.更多还原
