The invention provides a bacteriophage and application of the same to soil remediation. The bacteriophage Phi YSZPK is preserved in China Center for Type Culture Collection on August 01, 2018, under the accession number of CCTCC M 2018516, and is classified and named as Pseudomonas aeruginosa and Klebsiella phage Phi YSZPK. Biomass charcoal and the screened bacteriophage are used in combination and returned back to contaminated soil to synergistically prevent and control and deeply track the propagation and spreading of resistant pathogenic bacteria and resistant genes in an inactivated soil-vegetable system; the combined use of the biomass charcoal and the bacteriophage has positive promotion effect on the functional stability of microbial communities in the soil-vegetable system, effectively alleviates the spreading of resistant pathogenic bacteria in the soil-vegetable system and prevents secondary pollution; so a novel solution is provided for bioremediation and treatment of farmland soil contaminated by antibiotic resistant pathogenic bacteria in China.
