Screening method of microorganisms for relieving soil acidification, burkholderia polyphaga and application of burkholderia polyphaga

The invention discloses a screening method of microorganisms for relieving soil acidification, burkholderia polyphaga and application of the burkholderia polyphaga, and belongs to the technical field of agricultural microbiology and biological control. According to the screening method, a benzoic acid inorganic salt culture medium is selected for screening, and then gene sequencing is carried out, so that a microbial strain for relieving soil acidification, namely Burkholderia polyphaga BJS-3, is identified. When tobacco is planted, the special strain is applied to soil by adopting a special application method, so that the pH value of the soil can be remarkably increased, continuous cropping obstacles of the tobacco caused by benzoic acid secreted by roots of the tobacco are effectively avoided, the soil acidification is relieved, and the soil fertility is improved; the method is safe and pollution-free to the environment, and has good development prospect and application potential. 本发明公开一种缓解土壤酸化的微生物的筛选方法、多噬伯
