Abstract: A root nodule growth-promoting Microbacterium sp. X-18 and application thereof are provided, relating to the technical field of microorganisms. The root nodule growth-promoting bacterium is classified as Microbacterium sp. X-18, preserved in China Center for Type Culture Collection with a preservation date of Apr. 8, 2019 and a preservation number of CCTCC No: M 2019236; and the preservation address is Wuhan University, Wuhan, China. The Microbacterium sp. X-18 of the disclosure is applied to the leguminous plant Robinia pseudoacacia, which can promote the effective nitrogen fixation of Robinia pseudoacacia, provide the nitrogen required for the growth of Robinia pseudoacacia, and give full play to the symbiotic nitrogen fixation ability of the root nodule growth-promoting growth promoting bacteria and plants, so as to promote the growth and development of Robinia pseudoacacia plants, and has a promising development prospect.

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%.
