Embodiment 1
[0037] The AMF mycorrhizal inoculum is formulated with Moses capsule mold agent, and contains 25 mature and healthy spores per gram of substrate.
[0038] The PGPR bacterial agent is a liquid bacterial agent of Paenibacillus colloidus or Bacillus megaterium with a concentration of 10 8 CFU / ml.
[0039] Superphosphate is not added in the described nursery soil.
[0040] Comparison of the growth of Aurantium citrus seedlings without inoculation, single inoculation with AMF and joint inoculation with AMF and PGPR at 5 months (significant difference P<0.05).
[0041]
[0042] Note: Different letters after the values in the table indicate significant differences (LSD analysis), the same below.
Embodiment 2
[0044] The AMF mycorrhizal inoculum is formulated with the root capsule mold agent, and contains 25 mature and healthy spores per gram of substrate.
