Abstract: An Arthrobacter pascens X-1 for promoting a growth of nodules and increasing an abundance of probiotic microorganism populations is disclosed. After the Arthrobacter pascens X-1 provided by the disclosure is applied, nutrient elements required by plants such as potassium, calcium and magnesium in rock powder are effectively released, rock erosion is accelerated to form soil, simultaneously effective nitrogen fixation of soybeans is promoted, nitrogen required for soybean growth is provided, symbiotic nitrogen fixation capability of rhizobium and host plants is obviously exerted, total weight of root nodules is promoted to be increased by 150.00%, content of hydrolyzed nitrogen is improved to be increased by 11.58%, and symbiotic nitrogen fixation capability is effectively exerted. At the same time, the relative abundance of Bradyrhizobium in the soil is increased from 0.21% to 52.47%.
