This invention discloses a
microbial composition, a gel material, a preparation method, and its application in
afforestation of
saline-alkali land, belonging to the field of microbial technology. It is composed of *Bacillus curvaturetus* (…). Bacillus bent E1, Bacillus argentea ( Bacillus aryabhattai Composed of GPR018 and
lactic acid bacteria; Bacillus curvatureis (
Bacillus flexus The accession number for E1 is CGMCC No. 31832. The
surface charge of these three microorganisms can synergistically interact with the gel network of the gel material, effectively inhibiting the excessive adsorption of
sodium ions from the soil by the
polymer lattice of the gel material. This reduces the risk of secondary soil salinization caused by the gel material lattice's "only adsorption and
no release" of
sodium ions, fundamentally solving the problem of soil salt accumulation caused by the retention of
sodium ions during the repeated water absorption and release process of traditional water-retaining agents.
