摘　　要：通过水培和盆栽试验,研究了不同浓度BS-12污染对小麦种子萌发与小麦幼苗生长的影响。结果表明,水培中10 mg/L的BS-12能够促进小麦种子萌发,BS-12浓度大于10 mg/L时,随BS-12浓度增大小麦萌发受到的抑制作用增大;土壤中BS-12添加比例以0.5%为分界点,高于0.5%时小麦幼苗受到伤害与抑制作用,低于0.5%时小麦幼苗受到促进作用;BS-12对小麦地下部的伤害大于对地上部的伤害。The effects of different concentrations of aphoteric surfactants BS-12 on seed germination and seedling growth of wheat were studied with water culture and pot experiments.The results showed： The BS-12（10 mg/L） can promote wheat seed germination in water culture,while the BS-12（10 mg/L）can inhibit it;the BS-12（≤0.5%）can promote the wheat seedling growth in the pot experiments,while the BS-12（0.5%）can inhibit it;the damage of BS-12 on underground part of wheat was greater than on the above ground part.
