Nitrogen-fixing bacteria and use thereof

Abstract

The present invention relates to the technical field of microorganisms, and in particular to nitrogen-fixing bacteria and use thereof. The nitrogen-fixing bacteria include Kosakonia sacchari LWNF014 and/or Klebsiella variicola LWNF004. The Kosakonia sacchari LWNF014 was screened from the farmland in Gongzhuling, Jilin Province, with an accession number of CGMCC No. 28352, and the Klebsiella variicola LWNF004 was screened from the farmland in Gongzhuling, Jilin Province, with an accession number of CGMCC No. 28351. The aforementioned strains have nitrogen-fixing capability, can form an efficient interaction with corn, and can accelerate the growth process of corn, improving the chlorophyll content of leaves. The related strains are used for preparing an efficient microbial agent, which has the advantages of low production cost, simple operations, no secondary pollution to the soil, and the like.
