Malus sieversii grows on the slopes of the Tianshan Mountains in Xinjiang where the difference in daily temperature is significant. In recent years, the rhizosphere soil health of  Malus sieversii  has been severely impacted by anthropogenic disturbance and pathogenic infestation. The soil nutrient content and soil microorganism diversity are the main components of soil health. Low temperature has negative effects on soil bacterial community structure by inhibiting the accumulation of carbon and nitrogen. However, the effects of temperature and nitrogen application on soil carbon and nitrogen accumulation and the bacterial community composition in the rhizosphere soil of  Malus sieversii  are unclear. We set two temperature levels, i.e., low temperature (L) and room temperature (R), combined with no nitrogen (N 0 ) and nitrogen application (N 1 ) to explore the response of plant carbon and nitrogen uptake, rhizosphere soil carbon and nitrogen accumulation and bacterial community composition to temperature and nitrogen fertilization. At the same temperature level, plant  13 C abundance (P-Atom 13 C), plant  15 N absolute abundance (P-Con 15 N), soil  15 N abundance (S-Atom 15 N) and soil urease, protease and glutaminase activities were significantly higher under nitrogen application compared with the no-nitrogen application treatment. The bacterial community diversity and richness indices of the apple rhizosphere soil in the N 1  treatment were higher than those in the N 0  treatment. The relative abundances of  Actinobacteria ,  Rhodopseudomonas , and  Bradyrhizobium  were higher in the LN 1  treatment than in the LN 0  treatment. Redundancy analysis (RDA) showed that plant  13 C absolute abundance (P-Con 13 C) and plant  15 N absolute abundance (P-Con 15 N) were the main factors affecting the soil bacterial community composition. In summary, Nitrogen application can alleviate the effects of low temperature stress on the soil bacterial community and is of benefit for the uptakes of carbon and nitrogen in  Malus sieversii  plants.
