Species and Functions of Rhizobia Growing on Trees and Colonization Mechanisms

摘要

The current research progress in China shows that the tree species of rhizobia that have been found are mainly trees of 11 genera in Papilionaceae,Elaeagnaceae and Mimosaceae,and the rhizobia are mainlyα-rhizobia,which come from multiple genera.Temperature,pH value,NaCl content and antibiotics all affect the growth of tree rhizobia;and different species of rhizobia have different stress resistance,which is related to their living environment.Rhizobium inoculation can promote plant height,biomass,root-to-shoot ratio,and root architecture of trees.We discussed and analyzed the development history and application status of rhizobia research,and prospected their future development directions.In the future,tree rhizobia will surely be used as a means of production to promote efficient agricultural production and sustainable agricultural systems.
