摘要：

A field experimentwas conducted to investigate the effect of bean stalk (BBC) and rice straw (RBC) biochars on the bioavailability of metal(loid)s in soil and their accumulation into rice plants. Phytoavailability of Cd was most dramatically influenced by biochars addition. Both biochars significantly decreased Cd concentrations in iron plaque (35–81 %), roots (30–75 %), shoots (43–79 %) and rice grain (26–71 %). Following biochars addition, Zinc concentrations in roots and shoots decreased by 25.0–44.1 and 19.9–44.2 %, respectively, alth...
