The invention relates to the field of agricultural microorganisms, and in particular relates to a rhizobium pusense capable of degrading apple autotoxin phlorizin and application thereof. A rhizobiumpusense YIC4105 is preserved in China General Microbiological Culture Collection Center (CGMCC) on November 2rd, 2017 with the preservation number of CGMCC No.14852. The bacterial strain is separatedfrom sesbania rhizosphere soil naturally distributed at the Yellow River delta and is obtained through artificial separation and purification; the bacterial strain has relatively strong capability ofdegrading phlorizin and can be stabilized and colonized at rhizosphere of apples; and successive cropping obstacle of an apple seedling caused by accumulation of phlorizin can be effectively preventedby utilizing the bacterial strain, so that the rhizobium provided by the invention has good prospect of being developed into a microbiological inoculants or bacterial fertilizer capable of promotingcrop growth.
