摘要
分析了内蒙古节水工程土默特左旗试验地段在不同季节、不同层次土壤的基本农化性状和有效微量营养元素 .结果表明 ,土壤呈碱性 ,土壤养分显示出钾素丰富、氮素偏低、磷素缺乏状态 ,且这些养分在土壤耕作层中的分布高于心土层 ;土壤有效微量营养元素则在耕作层与心土层中的含量无显著差异 .
The Tuzuo Banner's Region,Inner Mongolia has been selected,and the basic agrichemical properties and active metals of different layers at different seasons have been studied for water-saving engineering.The results obtained in the study show that soil presents alkaline,and K element is rich,N element a little low,and P element poor in soil nutrient,and that these nutrient profile is higher in the forming soil layer than in the subsoil layer.But the active metal don't have obvious difference in the two layers.
