Abstract：Toexploretheefectsofdiferent microbialinoculantsonthecompostigofsilkwormexcrementandmulberryranches this study established four composting treatments： blank control （CK）， inoculation of 0.2% Bacillus subtilisand Bacillus faecalis mixed suspension （T1）， inoculation of 0.5%B subtilis and B. faecalis mixed suspension （T2），and inoculation of 0.5% Trichoderma koningii suspension （T3）.Thephysicochemical properties，humificationdegree，andlignocelllosedegradationrate werecomparedamong diferentreatments.Theresultsshowedthatthetemperaturesofthefourpilespresentedsimilar rendsandmettherequirementsof high-temperatureharmlestreatment.ThepHofthecompostinchtreatmentfistelevatedandthendecliedovertimefallngwithn therangeof7.9to8.3at teedofcomposting.Tdemonstratedtebestutrintaccuulationpeformance，witteighestcotent of totalnitrogenandavailablephosphorus.Attheendofcomposting，T2 had the highestlignocellulosedegradationrate （61.40%） whichwassignificantlyhigherthanthoseofotherreatments.Moreover，T2hadthehighesthumicacidcontent.Inconclusion， inoculation of 0.5%B subtilisand B⋅ faecalis mixed suspension promoted the nutrient accumulation， lignocellulose degradation，and humificationofsilkworm excrement and mulberry branches duringcomposting，serving as theoptimal scheme forimproving the composting efficiency and product quality.
