摘要:
通过检测分析青海省东部富硒土壤中硒的含量、赋存形态和价态,旨在为正确评价青海省东部土壤的富硒状况,有效利用富硒土壤资源及富硒农产品的开发提供理论依据。结果表明,青海省东部富硒土壤全硒含量变幅为0.342~0.770 mg/kg,平均值为0.487 mg/kg,是我国土壤平均硒含量的1.68倍,远大于全国土壤硒含量的平均值,属于足硒到中等高硒水平。供试土壤中可溶态硒、可交换态及碳酸盐结合态硒和残渣态硒分别占全硒含量的 10.91%~21.35%、11.56%~23.52%、11.69%~23.98%,铁锰氧化物结合态硒含量最少,占全硒含量的3.52%~11.82%;而有机结合态硒占土壤全硒含量的比例高达27.49%~50.65%,平均值为36.55%,土壤中硒的赋存形态主要以有机结合态为主。对土壤硒价态的研究表明,可溶态硒和可交换态及碳酸盐结合态硒中均存在Se4+、Se6+,不存在Se2-,且以Se6+为主要赋存形态。青海省东部富硒土壤分布集中,含量适宜,供硒潜力巨大,具有良好的开发利用前景。
