Abstract： Through field investigation，it was found that ginger was easily broken atthe junction of ginger headand ginger rootduring harvesting.Inordertoexplorethediferencesinmechanicalpropertiesbetwendiferentvarietiesof gingerand toprovidea theoreticalbasis forthe developmentofpull-upmechanized harvestingequipment，thispapercarriedout mechanical property testson three typical ginger varietiesandobtainedthe ultimate tensile strength atthe junction of ginger hadand theultimate bending strengthatthe junctionof gingerroot.Theexperimental designandanalysis byusing Design—Expert13softwareshowedthatthetensilestrengthofthefailurelocationof gingerheadfirstdecreasedand then slightlyincreasedwiththeincreaseof lifting angle，andfirstslightlyincreasedandthengraduallydecreasedwith the increaseofloadingspeed，besides therelationshipwasquadratic function.Inordertofurther optimizetheoptimal lifting speedandlifting angle，thetestfactors were designedandoptimized byusing thecentercombination testdesign，and the lifting speed range was 1362-1486mm/min ，and the lifting angle was 11∘-12∘ . The bending test on the root of ginger showedthat the maximum bending normal stressof the failure location of ginger connection decreased gradually with the increaseof pressure positionand graduallywiththe increaseof loading speed．When the bending normal stress of the failure location of ginger connection was maximum，the loading position was 52-58mm ，and the speed was 1 472— （204 1 519mm/min .Moreover，when Anqiu red sprouted ginger was harvested by the lifting ginger harvester，the ginger head and gingerconection were more easily damaged than the other two varieties.Therefore，when optimizing and improving theginger harvester，itisnecessarytoconsidertheapplicabilityof diferentgingervarietiestothemachinery，and synthesize the mechanical propertyof various varietiesof ginger tocomplete the mechanical design，ultimatelyachieving cost reduction in ginger production.
