By adopting the method for repairing the side slope, heavy metal in soil can be removed, the side slope can be greened, and the side slope is gradually covered year by year.

The invention relates to the technical field of microorganisms and biological fertilizers, in particular to a vicia sativa growth-promoting and stress-resisting complex microbial inoculant and a preparation method thereof.The complex microbial inoculant is formed by mixing arthrobacter, bacillus pumilus, bacillus flexus and brevundimonas intermedia according to the proportion of the arthrobacter, the bacillus pumilus, the bacillus flexus and the brevundimonas intermedia, and the effective viable count in the complex microbial inoculant is 1 * 10 < 9 >-10 < 10 > CFU / g; the synthetic bacterial agent produced by the invention can be applied to the planting and production process of vicia sativa as bacterial fertilizer, and is convenient to apply and remarkable in growth promoting effect. The microbial agent not only can accelerate the accumulation of vicia sativa biomass and improve the production performance, but also can help vicia sativa to resist various environmental stresses, so that the viability of vicia sativa in a severe environment is guaranteed. The method has important significance for improving the production capacity of the common vetch and promoting the development of animal husbandry.

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.

The application belongs to the field of agricultural microorganism technology, and discloses a bacillus curvatus strain BJ699 and application thereof in strawberry production. Bacillus flexus The application provides a new bacillus curvatus (BJ699) strain, and the preservation number of the strain BJ699 in China Typical Culture Collection Center is CCTCC NO:M20252013. The application further provides a microbial inoculant containing the strain BJ699 as an active ingredient and application thereof in preparation of a microbial inoculant for preventing and controlling a strawberry root rot pathogen and / or degrading pyraclostrobin. The new strain or the microbial inoculant containing the strain in the application is from a natural environment, has no cross-resistance with existing bactericides and insecticides, has the advantages of high efficiency, low toxicity, no environmental pollution and no easy generation of drug resistance, and has a wide application prospect.

The invention discloses a microbial composition, a gel material, a preparation method and application of the gel material in afforestation in saline-alkali soil, and belongs to the technical field of microorganisms. The bacillus flexus strain is prepared from bacillus flexus E1, bacillus aryabhattai GPR018 and lactic acid bacteria, and the bacillus aryabhattai GPR018 is prepared from bacillus flexus E1, bacillus aryabhattai GPR018, bacillus amyloliquefaciens and bacillus amyloliquefaciens. The preservation number of the bacillus flexus E1 is CGMCC (China General Microbiological Culture Collection Center) No.31832. The bacillus flexus E1 has the advantages that the preservation number is CGMCC Surface charges carried by the three microorganisms can generate a synergistic effect with a gel network of the gel material, excessive adsorption of gel material polymer lattices on sodium ions in soil can be effectively inhibited, and the risk of soil secondary salinization caused by the fact that the gel material lattices only absorb and do not release the sodium ions is reduced. The problem of soil salt accumulation caused by immobilization of sodium ions in the repeated water absorption-release process of a traditional water-retaining agent is fundamentally solved.

The invention belongs to the technical field of seedling substrate preparation, and particularly relates to a cigar tobacco seedling substrate and a preparation method and application thereof. The cigar tobacco seedling raising substrate is prepared from the perlite, the decomposed livestock and poultry manure, the vermiculite, the bacillus flexus and the bacillus coagulans through fermentation, and the cigar tobacco seedling raising substrate not only can improve the emergence rate of cigar tobacco, but also can accelerate the growth of cigar tobacco seedlings.

The invention provides a combined remediation method for petroleum-contaminated soil. The method comprises the steps that urea peroxide, sodium carbonate and to-be-treated petroleum-contaminated soil are evenly mixed and react at the room temperature under the condition that the water-to-soil ratio is 1: 1-1: 4, and based on the mass of the to-be-treated petroleum-contaminated soil being 100%, the adding amount of urea peroxide is 1%-3%; the molar ratio of urea peroxide to sodium carbonate is 1: 1-5: 1; a microbial agent is added into the reacted soil, and microbial remediation is conducted under the condition that the soil humidity is 20%-50%; wherein the microbial agent is biochar-loaded mixed bacteria, the mixed bacteria comprise pseudomonas aeruginosa, acinetobacter venetii, bacillus flexus, bacillus aryabhattai and bacillus megatherium, and the particle size of the biochar is 30-80 meshes; the adding amount of the microbial agent is 1%-5% by taking the mass of the to-be-treated petroleum-contaminated soil as 100%.
