摘要：e.e.y ye.r mushroom waste. are.produce. in big volume. from e.ible.mushroom production industrie.. Ve.micomposting te.hnology using e.rthworms as ve.satile.natural biore.ctors for e.fe.tive.re.ycling of organic waste. to the.soil is an e.vironme.tally acce.table.me.ns of conve.ting waste.into nutritious composts for crop production. This study was unde.take. to use.e.rthworms （e.se.ia foe.ida） in ve.micomposting on e.ible.mushrooms waste.. The.Randomize. block de.ign with thre. tre.tme.ts in Kimia, Sabalan and Artashahr mushroom production industrie. we.e.se.e.te. and four re.lications we.e.applie. for tre.tme.ts. The.total biomass of e.rthworms was e.timate. by counting the.numbe. of adults, juve.ile. and cocoons from e.ch re.lication. The.numbe. of adult and mature.worms, e.g capsule. and we. we.ght of e.rthworms we.e.re.orde. in one.month inte.vals （totally in five.months）. Ve.micomposting was carrie. out by the.e.worms in four months in spite.of de.ay in the.r e.tablishme.t in mushroom waste.. The.worms we. we.ght, the.r numbe. and the.numbe. of capsule. we.e.incre.se. up to fourth month and the. de.re.se.. The.produce. ve.micompost had suitable.prope.tie. for ame.ding soil.
