A preparation method of a Pueraria lobata nano-silver composite hydrosol includes: dispersing Pueraria lobata powder in water, then heating to perform gelatinization, then adjusting a pH value, then sequentially adding an alkyl polyglucoside solution, a silver nitrate solution, and a sodium chloride solution, and performing a reaction by microwave heating to obtain the Pueraria lobata nano-silver composite hydrosol. The Pueraria lobata nano-silver composite hydrosol promotes seed germination of a Polygonatum Mill genus, and is applied in antibiotic detection and agricultural sterilization used as a fungicide. Organic solvents, harmful reducing agents, and dispersing agents are completely avoided to be used, and raw materials for preparing the hydrosol are safe and environment-friendly; the preparation method is simple, no harsh conditions are needed, and reaction conditions are mild; a required time is extremely short, energy is saved, consumption is reduced, and a basic principle of green chemistry is completely met.
