The invention relates to the technical field of industrial microorganisms, and particularly discloses a P.megatherium HHY-1, a microbial agent thereof and application of the P.megatherium HHY-1. The preservation number of the P.megaterium HHY-1 is CGMCC (China General Microbiological Culture Collection Center) No.34470, and the preservation number of the P.megaterium HHY-1 is CGMCC No.34470. The P.megatherium provided by the invention has multiple functions of nitrogen fixation, phosphorus solubilization, siderophore production, IAA production capacity, antioxidant enzyme activity and the like, can play a comprehensive role from multiple dimensions of nutrition supply, growth regulation, stress resistance protection and the like, effectively assists good growth of the Abajie wheat 19 in a saline-alkali environment, and has a good application prospect. The method has great significance in improving the yield of the drought alkaline wheat in the saline-alkali soil and promoting agricultural sustainable development, and shows extremely high practical value in the aspect of growth promotion of the drought alkaline wheat Gie wheat 19.

The present invention provides a strain and application for degrading Quizalofop-PhD, which solves the technical problem that the degradation effect of Quizalofop-PhD by microorganisms in the prior art is poor. The present invention provides a strain and application for degrading Quizalofop-PhD, and the biological collection number is CGMCC No.31610; the strain is named MJ-8; the MJ-8 strain belongs to P. gigantea. The MJ-8 strain can effectively degrade Quizalofop-PhD to generate products with low or no toxicity. And the MJ-8 strain can grow in a culture medium containing Quizalofop-PhD, which shows that it can adapt to the presence of Quizalofop-PhD and can use Quizalofop-PhD as a carbon source for metabolism. This ability gives the MJ-8 strain huge application potential in the actual field of bioremediation, and the use of the MJ-8 strain for bioremediation can avoid the generation of secondary pollution. In addition, the degradation rates of the MJ-8 strain for clodinafop-butyl, high-efficiency fluazifop-butyl, cyhalofop-butyl, fluazifop-butyl and diclofenac all reached more than 90%, providing a basis for the application of the MJ-8 strain in agricultural soil pollution remediation.

The present application relates to the field of biological control, in particular to a kind of rape sclerotinia rot prevention and control agent and preparation method thereof.The rape sclerotinia rot prevention and control agent provided by the present application includes enterobacter cloacae fermentation liquor, methylotrophic bacteria fermentation liquor, trichoderma viride fermentation liquor and leptosporella gigantea fermentation liquor.The rape sclerotinia rot prevention and control agent is sprayed on the surface of rape at seedling stage, which can effectively prevent and control rape sclerotinia rot, and the field control efficiency reaches 79%;And enterobacter cloacae, methylotrophic bacteria, trichoderma viride and leptosporella gigantea have obvious synergistic effect in the prevention and control of rape sclerotinia rot.The present application provides a new combined microbial agent for preventing and controlling rape sclerotinia rot, which has wide application prospect due to wide source and remarkable effect.

The present application relates to the field of environment-friendly biological rare earth recovery technology, and particularly relates to a Priestia megaterium MeR-2 and a method for leaching rare earth elements from waste materials. Specifically, the present application provides a method for leaching rare earth elements from waste materials by using microorganisms and their metabolites, which solves the problems of large amount of chemical reagents, high production cost, serious environmental pollution and the like in the process of chemical leaching of rare earth waste materials. The strain provided by the present application has low cultivation cost, fast growth speed, simple leaching conditions, and has leaching capacity for rare earth ions in various waste materials, and has good application prospect in the aspects of microbial recovery and reuse of rare earth waste materials.

This invention discloses a type of endophytic fungus, *Priscilla megaterium*, with antibacterial activity, and its applications. The *Priscilla megaterium* is named... Priestia megaterium The strain, g-2-2, has the accession number CGMCC No. 37094. This invention screened and isolated a strain of *Priscilla gigantea* with antibacterial activity, g-2-2. Identification using morphology and 16S rRNA biotags confirmed g-2-2 as *Priscilla gigantea*. This strain exhibits significant inhibitory activity against harmful *Verticillium* species and can be used as a biocontrol agent.

The present invention provides a cultivation method for promoting pepper growth and capsaicinoid production, comprising the following steps: inoculating peppers with arbuscular mycorrhizal fungi during seedling cultivation, inoculating the peppers with a suspension of Priesteria gigantea 7-10 days after transplanting the pepper seedlings, spraying the peppers with a foliar fertilizer containing the Priesteria gigantea suspension at the initial stage of fruit setting, and finally spraying the peppers with abscisic acid 10-15 days before harvesting. This method, based on the nutrient requirements of peppers during different growth stages, selectively applies fertilizer types and dosages at different times, effectively promoting pepper seedling growth and increasing the capsaicinoid content of pepper fruits. The method has a short production cycle and is simple to operate.

The invention discloses a preparation method of pure natural perfume with ficus tikoua bur (ficus tikoua bur) essential oil as a single main body, and belongs to the technical field of natural perfume. According to the invention, the ficus tikoua bur essential oil is used as a unique essence base, artificial synthetic essence is not added, the ficus tikoua bur essential oil is only compounded with a compliant natural carrier, and the pure natural perfume with stable fragrance, pure fragrance and extremely high identification degree is prepared through low-temperature aging and precise filtration. The perfume is simple in formula, natural and low in sensitivity, the process can be industrialized, the problems that traditional single natural essential oil perfume is insufficient in fragrance structure and difficult to productize are solved, and the perfume is suitable for brand development of high-end natural perfume.
