Method for spraying robinia pseudoacacia on exposed shale walls to efficiently and rapidly restore green and improve soil ph value

A method for spraying Robinia pseudoacacia on exposed shale walls to efficiently and rapidly restore green and improve soil pH value, comprising:

• spraying a microbial mixed bacteria, an organic fertilizer, and a soil on a slope protection soil of the exposed shale walls in an external-soil spray seeding manner with a spraying thickness of 8-10 cm and a green plant of Robinia pseudoacacia;
• wherein the microbial mixed bacteria and the leguminous nitrogen-fixing bacteria are used synergistically to promote a rapid growth of Robinia pseudoacacia on the exposed shale walls and a rooting in crevices of the exposed shale walls;
• the exposed rock walls are quickly re-greened and the soil pH is improved;
• the leguminous nitrogen-fixing bacteria come from Robinia pseudoacacia;
• the microbial mixed bacteria comprises Kocuria sp. X-22, Microbacterium sp. X-26, Bacillus sp. X-28 and Microbacterium sp. X-18;
• the Kocuria sp. X-22 is preserved in China Center for Type Culture Collection with a preservation date of Apr. 8, 2019, a preservation number of CCTCC No:
• M 2019237 and a preservation address of Wuhan University, Wuhan, China;
• the Microbacterium sp. X-26 is preserved in China Center for Type Culture Collection with a preservation date of Apr. 8, 2019, a preservation number of CCTCC No:
• M 2019238 and a preservation address of Wuhan University, Wuhan, China;
• the Bacillus sp. X-28 is preserved in China Center for Type Culture Collection with a preservation date of Apr. 8, 2019, a preservation number of CCTCC No:
• M 2019239 and a preservation address of Wuhan University, Wuhan, China;
• and
• the Microbacterium sp. X-18 is preserved in China Center for Type Culture Collection with a preservation date of Apr. 8, 2019, a preservation number of CCTCC No:
• M 2019236 and a preservation address of Wuhan University, Wuhan, China.
