摘要
安徽省××地区土壤Se含量≥0.4mg/kg的面积100km^2,富硒土壤受湖泊沉积环境控制。富硒区土壤环境质量低于土壤三级标准限值,农业营养元素K2O、N、有机质丰富。精米Se含量≥0.04mg/kg.高于对比区两倍,重金属元素未超标。
Soil with Se ≥0.4mg/kg covering an area of 100km^2 in a place in Anhui Province is in the control of lake sedimentary environment. The soil environment quality of the Se-rich area is lower than soil standard class-3, but it is abundant in agricultural nutrient elements as K2O, N and organic substances. Polished rice has Se content ≥ 0.04mg/kg, two times higher than that in compared area, with heavy metals not exceeding the standard level.
