Earthworm feces has gradually become a good organicfertilizer，but the mechanism and process of earthwormprocessing on the properties of organic fertilizers are not clear. Mixtures of dairy manures and mushroomresidues(volume ratio is 2 ∶1)by adding Rw fermentation bacteria were prepared to let the treatment temperature increase and maintain a period times of high-temperature. After the temperature was below 50 ℃，the earthworms were piled up for the treatment， and the processing physical and chemical properties of the treatment were analyzed after 45 days.The results showed that thecomposting temperature，NH 4+-N content，NH 4+-N/ NO^3--N，T-value，pH value，EC value and seed germination index all met the maturity requirements. Combined composting significantly increased total phosphorus content and NO^3--N content(P<0.05)by 16.8% and 1 286.1% respectively，compared to the original mixture. However，the organic matter content，total potassium content，pH and EC value significantly( P<0.05)decreased by35.9%，77.4%，12.6% and 56.1%respectively.In addition，the combined composting reduced the content of NH 4+-N and total nitrogen，but not significant(P>0.05)；And it significantly improved the quality of compost，such as the T value of the combined compost was0.58，which was lower than the Tvalue(0.64)before adding earthworm and the seed germination index of the compost was90.6%，which was significantly higher than that of the seeds before addingearthworm(82.6%)(P<0.05).
