Abstract：Thecontinuous cropping patern of soybeans can lead to the deterioration of soil physical and chemical propertiesandadecrease insoil enzyme activity.Toalleviate thecontinuous cropping obstacleandenhance soybeanproductivity，inthisstudy，biocharandTrichodermainoculantswereappliedtothesoil，andtheeffectsonthenutrientsandenzymeactivitiesof soybean rhizosphere soilaswellasthe agronomic traitsof soybeans were explored.Theresearchresults showed thatthe treatmentofbiochar combined with the Trichoderma harzianum inoculantandthetreatmentofbiochar combinedwiththeTrichodermavirideinoculantsignificantlyincreasedthecontentsofavailablepotassum，alkali-hydrolyzable nitrogenandavailable phosphorus intherhizospheresoil，aswellastheactivitiesof urease，sucrase，catalaseandacid
