The invention relates to the field of microorganism, and discloses a microbiological strain for repairing heavy metal contaminated soil, and a screening method and application thereof. The preservation number of the microbiological strain disclosed by the invention is CGMCC (China General Microbiological Culture Collection Center) No. 10127. According to the screening method disclosed by the invention, a bacillus mycoides is screened from soil contaminated by heavy metal cadmium, exchangeable cadmium in the soil can be passivated by the bacillus mycoides, the content of the exchangeable cadmium can be obviously reduced, and meanwhile, a very strong tolerance on cadmium is also obtained; disturbance on the soil is small, a stronger biological repairing function is obtained, and the microbiological strain can be applied to repairing of the heavy metal contaminated soil and preparing of heavy metal contaminated repairing materials. 本发明涉及微生物领域，公开了种修复重金属污染土壤的微生物菌株及其筛选方法和应用。本发明所述微生物菌株保藏编号为CGMCC No. 10127。本发明从受重金属镉污
