| 摘 要： | 通过对杭嘉湖平原富硒区研究,发现区内富硒土壤主要分布在环湖平原区,土壤具有特殊的地球化学性质,表现为土壤酸性,土壤硒全量0.3～0.5 mg/kg,有机质含量高、重金属含量低,土壤质地较黏重,土壤硒与有机质关系密切,而与土壤pH相关性不明显等特点。在土壤有机质丰富和氧化条件下,农产品中硒含量较高,重金属低于限量标准,具有较好的开发远景。

| Abstract: | Based on the study of selenium - rich soil in Hangjiahu plain, that the selenium - rich soil distributed in the plain area around the Tai lake was found. It had a special geochemical characteristic. The soil was acidic and its content of selenium was from 0. 3 to 0.5 mg. kg^-1. The content of organic matter was high, the heavy metal content was low, and soil texture was heavy clay. According to the result of correlation analysis, the content of selenium had a close correlation with organic matter, but no obvious correlation with soil pH. In the condition of rich in soil organic matter and oxidized, the content of the agricultural products would be in a higher level and the content of heavy metals would below the limits, with the result of good development prospects |
