This invention discloses an endophytic bacterium for Epimedium with multiple disease-resistant and growth-promoting functions, its combination, and its application, belonging to the field of biocontrol technology. The endophytic bacterium for Epimedium described in this invention is *Bacillus belye* B-Y-2. The combination of endophytic bacteria for Epimedium in this invention includes *Bacillus belye* B-Y-2, *Bacillus halophilus* A-G-7, and *Bacillus subtilis* D-1. The endophytic bacteria and combination of this invention exhibit good inhibitory activity against the main pathogens causing Epimedium diseases, and possess nitrogen-fixing, phosphorus-solubilizing, and potassium-solubilizing effects. Icariin and IAA can be detected in the fermentation broth, which can increase soil nutrient content, promote plant growth, and improve Epimedium quality. When combined, they synergistically enhance their effects. As an effective component of foliar fertilizer for controlling Epimedium diseases, they have a long-lasting effect, good control efficacy, and are environmentally safe. When applied to the soil as a microbial fertilizer, they can increase the content of available nitrogen, phosphorus, and potassium in the soil, improve soil fertility, promote plant growth, and reduce the use of chemical fertilizers.

The invention belongs to the technical field of soil improvement, and relates to a planting method combining protective tillage with organic fertilizer application. The invention provides a planting method combining protective tillage with organic fertilizer application, which comprises the following steps: performing deep scarification before sowing, then applying modified starch, a microbial organic compound fertilizer and a nitrogen-phosphorus-potassium ternary compound fertilizer, and finally sowing crops, the modified starch is phosphorylated distarch phosphate or acetylated distarch phosphate; the effective viable count in the microbial organic compound fertilizer is more than or equal to 5 billion / g, and the organic matter content is more than or equal to 60%. According to the method, the influence of different cultivation modes and different auxiliary additives on the soil organic matter content and nutrient circulation is explored. In this way, the organic matter content of the soil can be protected and increased, and the fertility and stress resistance of the soil are enhanced.

This invention belongs to the field of agricultural microbiology technology, and discloses a strain of Sphingomonas, a microbial agent, its preparation method and application, specifically disclosing a strain of Sphingomonas (… Sphingomonas Microbial agent (sp.) R7 was deposited on March 31, 2025, at the China Center for Type Culture Collection (CCTCC), Wuhan University, Wuhan, China, with accession number CCTCC NO: M 2025634. The invention discloses a microbial agent containing this bacterium, its preparation method, and its application in improving soil and / or promoting rice growth, as well as in reducing cadmium content in the aboveground parts of rice.
