    摘要:

    调查研究了西藏拉萨至曲水拉萨河沿岸农用地土壤中硒锗的含量与分布状况,发现研究区内绝大部分农田土壤缺硒(<0.16 mg/kg),而大部分农田土壤富锗(≥1.3 mg/kg);土壤全硒、有效硒含量与pH不存在显著的相关关系,土壤全锗、有效锗含量均与pH表现为极显著的负相关关系,均与有机质含量表现为极显著的正相关关系。研究区整体土壤富锗情况较好,具有富锗土壤开发潜力,可以考虑富锗农牧产品的开发与推广。

    Abstract:

    The contents and distribution of Selenium (Se) and germanium (Ge) in farmland soils from Lhasa to Qushui along the Lhasa River in Tibet were investigated and studied. The results showed most of the farmland soils were deficient in Se (<0.16 mg/kg) while rich in Ge (>1.3 mg/kg). The contents of total Se and available Se had no significant correlations with pH, while the contents of total Ge and available Ge had negative significant correlations with pH but positive significant correlations with organic matter content. In general, soils in the study area are rich in Ge and has potential for the development and popularization of Ge-rich agricultural and animal husbandry products.
