Abstract:  In order to solve the problem of poor ammonia removal effect of single strain on livestock com posting,taking chicken manure and furfural residue as test materials,liquid fermentation test and site test were used to study ammonia removal effect of Pseudomonas sp.(A21) and Bacillus sp.(A38),Pseudo monas stutzeri(S33),Pseudochrobactrum saccharolyticum(S61) and their combination and explore the effects of different ammonia removal bacteria on composting process of composting materials.The results showed that,when the fermentation was finished,the pH value of the composting materials was between 7.58 and 7.77,and the water content decreased to 17.23%—21.34%.A21,S33 combination treated composting materials had the lowest cumulative ammonia release amount，the contents of organic carbon,total nitrogen，total phosphorus and total potassium were 36.02%,2.33%,2.28%,0.98%,respectively,which increased by 31.84%,37.06%,6.05%,15.29% compared with no bacterium addition treatment,respectively.The organic carbon content of the composting material decreased by 12.57%,and the total nitrogen content increased by 15.35% compared to chicken manure in basic materials.In summary,Pseudomonas sp.and Pseudomonas stutzeri combination could accelerate the maturity process of compos ting materials,reduce the loss of carbon and nitrogen,and increase total nutrient content.These aspects are superior to single bacterium or other combination treatments,and could be applied to chicken manure composting production practice．
