【摘要】 试验结果表明：重金属镉对“天府９号”、‘鲁花９号”花生品种的结瘤和植株生长均有影响。镉浓度在１００ＰＰＭ下，花生植株根系发育受到抑制，快生型花生根瘤菌株８５—７虽能侵染，但结瘤数量显著减少。更多还原

【Abstract】 The results indicate that cadmium heavy metal of would inhibit on nodule baeteria and the growth of No. 9 Tian-Fe peanut and No. 9 Lu-Hua peanut. The suppression of cadmium is 100 ppm of on peanut roots growth. The fast-growing peanut Rhizobium strains of 85-7 could infect but in fact reduced nodules number.更多还原
