Under the condition of conventional fertilization in calcareous soil of Shanxi Province, the peanut inoculated with excellent rhizobium had a remarkable effect, the nodulation number increased by 5 times, inoculation accounted for more than 70%, and the nitrogen supply rate in pot and field reached 4 5.6 ± 6.6% and 30% respectively .2 ± 3.3%, increasing the amount of nitrogen fixation 69.0 ~ 110.01 kg / hm2, 3.4 ~ 6.9 times higher than natural nodulation and nitrogen fixation. Rhizobium inoculation increased yield by 32.3 ± 11.8%, yield increased by 7.2 ± 4.7% in field and increased crude protein content by 3.0% -7.0%. Inoculation of rhizobia strains and interaction between rhizobia and silicate bacteria was not stable
