Abstract：Variable fertilization technologyplaysacrucialroleinimproving fertilizerutlization eficiency，increasing crop yields，and mitigating environmental polution.This paperreviews therecent advancements in keytechnologiesaociated withvariablefertilization，including prescriptiongenerationtechnology，variable fertilizationcontrolsystems，andthe designofactuatorcomponents forfertlizer dispensers.Currentchallenges were identified，suchasslowacquisitiooffield information，dificultiesinestablishingacuratefertizationmodels，andthelimitedresearchonintegratingvariable fertilization devices.Toaddress these chalenges，future research should focus on improving prescription mapgeneration byleveragingunmannedaerial vehicle（UAV）remote sensing technology toaccelerate field data colection.Conducting fieldexperiments inrepresentative farmlands across diverseregions can furtherrefine fertilization practicesandpromote scientificallyinformedfertilizationstrategies.Additionall，advancingthedesignanddevelopmentofvariablefertilization devices is essential toimprove theirstabilityandoverallperformance.Theseeffortsaimtodrivethepractical aplications of variable fertilization technology and support sustainable agricultural practices.
