摘要

摘要研究了不同基因型绿豆(Vigna radiata)在高砷水平(30 mg kg−1)土壤中生长、根、芽和籽粒对砷的吸收情况。施用任何一种土壤改良剂后,籽粒中砷含量平均降低45%。更具体地说,添加丛枝菌根真菌可使籽粒中砷浓度降低57%,添加硒可使籽粒中砷浓度降低60%。此外,品种间砷吸收也有很大差异。

Mycorrhizal fungi, biochar, and selenium increase biomass of Vigna radiata and reduce arsenic uptake
Abstract Growth and As uptake of mung bean (Vigna radiata) in roots, shoots, and grains of different genotypes grown in soil with high As level (30 mg kg−1) amended with arbuscular mycorrhizal fungi, selenium, and biochar was investigated. Arsenic content in grains was reduced on average by 45% with any of the soil amendments. More specifically, the As concentrations in grains were reduced by 57% with arbuscular mycorrhizal fungi and by 60% with Se amendments. Also, great differences in As-uptake between varieties have been observed.
