Identification and evaluation of the salt and acid alkaline resistance of rhizobium species of Desmodium
Inoculation with rhizobium can improve not only host yield and quality but also host adaptability to stress. The match between inoculated strains and hosts and resistance to stress are the key factors determining the inoculation effect. Four types of Desmodium, Pleurolobus gangeticus, Puhuaea sequax, Grona heterocarpos, and Polhillides velutina, were used to capture rhizobium strains in soil, and the classification status as well as salt and acid alkaline resistance of the strains were determined through isolation, identification and different salt and pH treatments.
