Abstract
Halophilic bacteria have special metabolic mechanism and physiological structure, which can change soil properties to
achieve economic benefits, and have great research value and development potential. The development of new salttolerant strains can tap the strain potential and contribute genotypes of new strains to the database. The ultimate goal is
to improve the crop yield, enrich the variety of planted crops and increase the utilization rate of saline-alkali land. So
as to improve the soil conditions to increase food production, protect the environment and green saline land and other
goals. Targeted enrichment method and liquid dilution coated plate method were used to isolate and screen bacteria
with high salt tolerance, and then phylogenetic analysis method based on 16S rDNA gene sequence was used to
establish the bacterial gene tree.
