The invention belongs to the field of microbial resources, and particularly discloses a strain of
Bacillus aryabhattai J5 and application thereof in promoting growth of corn. The
Bacillus aryabhattai J5 is collected in CGMCC (China General
Microbiological Culture Collection Center) on October 15th, 2015 and is filed with the number of CGMCC NO.11508. The
Bacillus aryabhattai J5 has functions of producing
auxin,
siderophore,
ammonia and
protease, dissolving
phosphorus, resisting to salt, realizing
antagonism, and the like. As the strain is capable of growing normally in a culture medium with
salt content equal to 11%, the strain has good potential in eliminating soil salinization. As content of
siderophore produced by the strain is up to 53.7%, the strain has effective
disease-prevention property. By the strain, corn seed
germination rate can be increased by 12.5%, and accordingly the strain has good
growth promoting effect. By application of microbial inoculum prepared from the strain, corn yield is increased by 37.1%, and hundred-
grain weight is increased by 35%. It is possible to develop the strain into microbial inoculum, and accordingly the strain has wide application prospect in terms of improving soil
nutrient, eliminating salinization, promoting growth of plants, preventing diseases and the like.
