摘　　要：采用纸片法和水培法,研究镉胁迫对花生根瘤菌和花生生长的影响。试验结果表明,镉浓度在50 mg/L以上,对根瘤菌的生长繁殖即有抑制作用,100 mg/L以上对花生结瘤和生长表现出较强的抑制作用,随镉浓度增大,抑制作用增强。Paper method and water culture were carried out to study the effects of Cd stress on the nodulation and growth of peanut.The results showed that the growth and reproduction of rhizobia were inhibited with the Cd of above 50 mg/L,and the inhibition was stronger with the Cd of above 100 mg/L,so the inhibition was enhanced with the increasing of the concentration of Cd.
