Abstract：【Objective】Toclarifythe efects of sodculture incherry orchards onsoil physicochemical propertiesand yield in southwestern Shandong.【Methods】The suitable grasspecies in cherry orchards in southwest of Shandong Province were selected，andthecleartilage wasusedasthecontrol.Theeffctsofryegrass，alfalfa，vetch，long-awnedwildpea，whiteclo ver and rape on soil physical and chemical properties，SPAD value and yieldof leaveswere studied.【Results】Theresults showed that intercropping grassincherry orchardcould reduce soil bulk density，increase porosityand field water holding capacity.Compared with thecontrol，planting long-awned wild peacan significantly increase thecontentof soil organic mater andavailable nitrogen.Planting alfalfa，vetch and whiteclovercan increase soil available phosphorus content.【Conclusion】 Whitecloverhas thebestefectinsixgrass varieties，whichcanimprove soil physicaladchemicalproperties，increase soil available nutrientsand increasecherry yield.Itisanidealchoiceforgrasscultivation incherryorchardsinsouthwest Shandong.
