摘要
在全省10个地市60多个县市11万亩菜田上取样（0～20cm）1086个，分析测定了微量元素硼、锰、钼、锌、铁、铜等养分含量。分析结果表明，菜田土壤有效硼含量为0．21～1．58mg／kg，平均为0.67mg／kg；有效锰含量为2．88～24．17mg／kg，平均为9．03mg／kg；有效锌含量为0．44～7.14mg／kg，平均为2．26mg；／kg；有效银含量为0．05～0．85mg／kg，平均为0．22mg／kg；有效铁含量为3.59～51．08mg／kg，平均为12．23mg／kg；有效铜含量为0．45～20．00mg／kg，平均为1．80mg／kg。在此基础上，提出了山西省菜田土壤微量元素应用区划。
1086 soil samples were collected in 110 thousand mu vegetable field in 60 counties in 10 cities of Shanxi province. Nutrient contents of B, Mn, Mo, Zn Fe,Cu etc were analysed. The results showed:the available B content in the soil of vegetable fields was 0. 21 ~ 1. 58mg/kg and the average was 0. 67mg/kg;the available Mn Content was 2. 88~24. 17mg/kg and the average was 9.03mg/kg,the available Zn contents was 0. 44~7.14mg/kg and the average was 2. 26mg/kg;The available Mo content was 0.05~0. 85mg/kg and the available Mo content was 0.05~0. 85mg/kg and the average was 0. 22mg/kg; the available Fe content was 3. 59~ 51. 08mg/kg and the average was 12. 23mg/kg; the available Cu contents was 0. 45~ 20.00mg/kg; the available Cu Content was 0. 45~20.00mg/kg and the avavage was 1. 80mg/kg. Applied division of minor elements in the soil of vegetable fields in Shanxi province was suggested.
