Abstract：Tosolve theproblems oflowoperation effciencyand insuffcient precisionof the leveling machine during grenhouseseedling cultivation，and incombination with the agronomicrequirementsof the greenhouse seedling bed leveling machine，a combined leveling machine composedof a mechanicaltransmissondevice andahydraulic system was designed.TheFluidSIMsoftwarewasused toconductsimulation testsonthe hydraulic system.Subsequently，hydraulic debuging was carredout，andthe responsesurface method was adopted to analyze the impactof diferent parameters on theoveralloperationefectof theoptimized hydraulicsystem.Combinedwith field tests，the optimalcombinationof parameterswas determined.Theresultsshowed thattheoptimized hydraulicsystem hada high degree offt with the levelingmachine，andthedebugging testsconfimedthatthestabilityoftheleveling machinewas closelyrelated to the hydraulic system. When the forward speed of the leveling machine was 1.1km⋅h-1 ，the vibration frequency of the tamping mechanism was 35Hz ，and the working time did not exceed 0.6h ，theleveling machine embedded with the optimized hydraulic system had a 5% improvement in flatness and a 50% improvement in soil solidness compared to the ordinary leveling machine.This hydraulic system significantly improved the operation accuracy of thecombined seedling bed leveling machine，making itscomprehensive performancereachedthebestlevel，and providingagoodbasic guarantee for the growth environment of rice seedlings.
