摘    要:以药渣为堆肥填料,蚯蚓粪为堆肥辅助菌剂,设计了A,B,C,D共4个处理组,进行好氧堆肥发酵.通过测定堆肥过程中的温度、pH、含水率、有机质、N H+4 N、速效磷、速效钾的变化,确定蚯蚓粪在药渣与污泥混合堆肥中的最佳配比.结果表明,采用处理C,即污泥∶药渣∶蚯蚓粪(w/w/w )=6∶3.6∶2时,堆肥质量最好.

关 键 词:蚯蚓粪  药渣  污泥堆肥  最佳配比

Abstract:Dregs are used as the filler and earthworm cast is taken as auxiliary bacteria .Four treatment groups called A ,B ,C ,D are designed to do the aerobic composting .In order to determine the best ratio of earthworm cast in dregs and sludge composing ,the changes of temperature ,pH ,Moisture content ,organ-ic matter ,N H+4 -N ,available P ,available K are measured in the composting process .T he results show that treatment C has the best quality .That is when sludge :dregs earthworm cast (w/w/w) is 6∶3∶2 .
Keywords:earthworm cast  drege  sludge compost  optimum ratio
