通过大田试验研究了水稻返青增蘖剂对水稻籽实重金属积累的抑制作用。结果表明:水稻返青增蘖剂能使水稻地上部重金属浓度显著降低,且远低于地下部浓度;显著降低地下部重金属的浓度,降低土壤中有效态重金属离子的浓度,抑制水稻对重金属的吸收和转运比例,降低稻米中重金属的含量。 Field experiments were conducted to study the inhibitory effect of turnip green tiller on heavy metal accumulation in rice seeds. The results showed that the rice returning green tiller could significantly reduce the heavy metal concentrations in the shoots, and much lower than those in the underground ones. The concentrations of heavy metals in the underground parts decreased significantly and the concentrations of available heavy metals in the soil decreased, And transport ratio, reduce the content of heavy metals in rice.
