The invention belongs to the technical field of agricultural microorganisms, and particularly relates to rhizobium capable of promoting plant cell division, resisting salt and alkali and reducing alkali and application of the rhizobium. The strain number of the Neorhizobium alkalisoli is YRD01, the preservation number of the Neorhizobium alkalisoli is CCTCC NO: M 20251990, and the Neorhizobium alkalisoli is preserved in China Center for Type Culture Collection, Luojia Hill, Wuchang District, Wuhan City, Hubei Province on September 9, 2025. The strain obtained by the invention is derived from sesbania root nodules and is obtained by screening and culturing the sesbania root nodules. The rhizobium (Neorhizium alkalisol) YRD01 obtained by screening in the invention is a strain of novel rhizobium which has the characteristics of high saline-alkaline tolerance, active alkali reduction function and efficient growth promotion.

The invention provides a sowing method for wheat-sesbania in a dry farming saline-alkaline double cropping area, and belongs to the technical field of agricultural sowing, and the sowing method comprises the following steps: S1, early-stage preparation; s2, shallow spinning and leveling; s3, sowing execution; s4, soil treatment; and S5, equipment resetting. The invention provides a wheat-sesbania seeding method for a dry farming saline-alkaline double cropping area. Through collaborative design of crop adaptation, soil improvement and equipment optimization, a multiple guarantee mechanism for yield stability is constructed. The yield reduction risk of unreasonable group structure of wheat is reduced through close planting optimization, biomass accumulation is improved through wide-distance planting of sesbania, and a green manure cycle of land use and land cultivation is formed; the rainwater collection ditch has the water collection and soil moisture conservation functions to buffer the influence of uneven rainfall and reduce the fluctuation impact of drought and flood on the yield. The method pertinently solves the core problems of insufficient adaptability, saline-alkali drought stress, low emergence rate and the like of the same seeder, and realizes double improvement of the emergence rate and the yield stability of the double-cropping product in the dry-farming saline-alkali area.

A preparation method of an ionic rare earth leaching agent includes the following steps: (1) domestication microorganisms with rare earth activated mineral powder culture medium to obtain a microbial suspension; (2) amplifying and culturing the microbial suspension and additives to obtain the amplified culture medium; and (3) mixing the modified sesbania gum with the amplified culture medium to obtain the ionic rare earth leaching agent. The activated mineral powder is the active metal-containing mineral powder in nature, which has excellent cation exchange function after activation, and the activated mineral powder and ionic rare earth mineral powder are used as the medium components to domesticate microorganisms, so that microorganisms can survive in the above-mentioned ionic solution and improve the leaching rate of synergistic leaching ionic rare earth.

The invention belongs to the technical field of agricultural biology, and particularly relates to a method for germinating sesbania seeds. The method comprises the following steps: collecting mature sesbania siliques, treating to obtain qualified seeds with uniform particle sizes, carrying out heat treatment on the obtained qualified seeds for 2 hours, grinding the seeds with fine sand to damage seed coats, soaking the seeds in hydrogen peroxide and gibberellin in sequence, and finally putting the soaked seeds in a saturated sodium bicarbonate environment with trace vent holes, germinating in a variable-temperature mode of illumination for 12 hours and darkness for 12 hours. According to the method, seed coat obstacles are broken through multi-step cooperative treatment, germination conditions are optimized, and the germination efficiency of the sesbania seeds can be remarkably improved.

The invention discloses recombinant rhizobium OEuspA with stress resistance, a plant salt-resistant bacterial agent and application of the plant salt-resistant bacterial agent, and belongs to the technical field of genetic engineering. According to the invention, a new uspA gene is identified from azotobacter stenoma ORS571 for the first time. And then carrying the uspA gene into the azotobacter stem nodule by using a plasmid vector, and constructing to obtain the recombinant rhizobium over-expressing the uspA gene. Compared with wild-type rhizobium, the stress resistance of the recombinant rhizobium for overexpressing the uspA gene, which is constructed by the invention, is remarkably improved. After the recombinant rhizobium over-expressing the uspA gene is symbiotic with sesbania eriocalyx, wheat and corn, the growth of plants under the salt stress condition can be promoted. The uspA gene disclosed by the invention can be used for constructing a recombinant rhizobium material with stronger stress resistance and growth promotion capability, and has potential and wide application prospects in the fields of genetic engineering transformation of rhizobium or other bacteria, the rhizobium microbial inoculum preparation industry, the bean planting industry in agricultural production and saline-alkali soil development.

The application belongs to the field of agricultural microorganism technology, and particularly relates to rhizobium promoting plant cell division, salt and alkali tolerance and alkali reduction and application thereof. Neorhizobium alkalisoli The rhizobium has a strain number YRD01 and a preservation number CCTCC NO: M 20251990, and is preserved in the China Typical Culture Collection Center in Luo Jia Mountain, Wuhan, Hubei on September 9, 2025. The strain obtained in the application is derived from sesbania root nodule and obtained after screening and culture. Neorhizobium alkalisoli The rhizobium YRD01 obtained in the application is a new type of rhizobium with high salt and alkali tolerance, active alkali reduction function and high-efficiency growth promotion characteristics.

The invention discloses a method for producing a silage raw material by intercropping sweet sorghum and sesbania cannabina, which can effectively improve the land utilization rate, improve the soil structure, improve the yield and quality of forage grass crops and reduce the breeding cost. According to the method, an intercropping mode is adopted, through reasonable configuration of the sweet sorghum and sesbania in time and space, the fresh and hay yield of the sweet sorghum can be effectively increased, the nutritional quality of mixed forage grass can be improved, and economic income can be increased; the problem of insufficient supply of local forage grass is solved, and the breeding cost is reduced; meanwhile, when the sowing rate ratio of the sweet sorghum to the sesbania is larger than 1: 1, growth of the sweet sorghum and the sesbania is benefited, it is indicated that the sweet sorghum and the sesbania form a stable coexisting competitive pattern, and after mixed sowing of the sweet sorghum and the sesbania, the problems that the gramineous protein content is low and the leguminous forage carbohydrate content is low can be solved to a certain extent; the fresh and hay yield and the nutritional quality of the mixed forage grass are greatly improved. The method is suitable for popularization and application in the technical field of forage grass planting.
