In recentyears，it has been widely reported that the incorporation of mineral additives can improve the compostingprocess，promote compost maturity，and accelerate the organic matter degradation.In this study，0%(A)，2%(B)，6%(C)and12%(D)of sericite were mixed with the compost under the same condition of theenvironment，materials andequipment to explore whether the sericite mixture will influence the shiitake bags waste compost and the plant growth ornot.Itshowed that the appearance of the composts which added sericte were more delicate than the control.The temperature duringcompost of treatment D maintained steadier high temperature than other treatments which was helpful tocomposting.During thecompostingtime，the changes of pH value went up rapidly in the firststage，and it became steady little by little till the fourthmonth.As to C/N，there was significant difference( F=11.241，P=0.003)after the completely composted，treatment Awas the lowest(8.7±0.3)while C was the highest(11.2±0.3).However，as the germinationrate，the treatment C with 6%content of sericite and the treatment D with 12% had higher germination，which were 99% and 97%respectively.ThroughAnalysis ofVariance(ANOVA)，it showed that both the length and the dry weight of the plants growing above the groundand under theground，the compost added with sericite was more distinctive than thecontrol.The results indicated thatadding sericite into the shiitake bags waste compost will not only help to enhance thecomposting，but also be helpful to theplantgrowth.Thus，it will become one of the options to the compostadditive.
