土壤重金属污染和盐碱化在农业土壤中分布广泛。研究了5种重金属和5种重金属污染盐对盐生植物盐生盐碱蓬种子萌发和幼苗生长的影响。结果表明，种子发芽率、鲜重(FW)、干重(DW)、胚根相对活力和离子(Cu2+、Ni2+、Zn2+、Cd2+、Pb2+)含量均高于对照。不同重金属和重金属污染100 mg/L氯化钠处理对肾小球的影响。无论加不加氯化钠，胚芽中的离子含量都随着重金属浓度的增加而增加。此外，在Cu2+、Zn2+和Pb2+浓度为100 mg/L的盐胁迫下，土壤中金属的积累水平均高于不加盐的处理。这可以为h的价值提供新的见解。用于受重金属影响的土壤的植物修复，也与盐度相结合。
Heavy metals pollution and salinization of soils are widely distributed in agricultural soils. This study investigated the effects of five heavy metals and five heavy metals-contaminated salt on seed germination and seedling growth of halophyteHalogeton glomeratus(H. glomeratus). The results showed that seed germination, fresh weight (FW), dry weight (DW), radicles relative viability and ion contents (Cu2+, Ni2+, Zn2+, Cd2+and Pb2+) ofH. glomeratuswere affected by different heavy metals and heavy metal-polluted 100 mM NaCl treatments. Ion contents in plumules increased with the increase of heavy metal concentrations with or without NaCl addition. Moreover, the accumulation levels of metals in the concentrations of Cu2+, Zn2+and Pb2+supplying 100 mM NaCl were higher than that without NaCl treatment. This can provide new insights into the value ofH. glomeratusfor phytoremediation of soil affected by heavy metals and also in combination with salinity.
