This invention provides a cyclohexene glycoside-based fertilizer for increasing crop yield and efficiency, its preparation method, and its application. The method first prepares an aqueous solution of the cyclohexene glycoside substrate, and then prepares a nutrient matrix consisting of at least two of nitrogen, phosphorus, and potassium components mixed with an organic carrier. Next, nutrient-converting functional bacteria and cyclohexene glycoside-activating functional bacteria are separately cultured and then compounded to form a synthetic bacterial agent with specific β-glucosidase activity and an effective viable count. The cyclohexene glycoside substrate is then loaded onto diatomaceous earth particles with high open porosity to obtain a stabilized carrier. Subsequently, the carrier, nutrient matrix, and synthetic bacterial agent are mixed, and granulated under the condition of adding a binder to obtain wet granules. Finally, the granules are dried at low temperature in two stages until the moisture content is ≤8 wt%, and then granulated to obtain the finished fertilizer. This fertilizer integrates the active components of cyclohexene glycosides, compound nutrients, and functional microorganisms, which can synergistically promote crop growth and nutrient utilization, and is suitable for a variety of crops, achieving increased yield and efficiency.
