摘要
为解决单一菌对禽畜堆肥除氨效果不佳的问题,以鸡粪和糠醛渣为试验材料,采用液体发酵试验和场地试验,研究除氨细菌假单胞菌(Pseudomonas sp.,A21)、芽孢杆菌(Bacillus sp.,A38)、施氏假单胞菌(Pseudomonas stutzeri,S33)、解糖假苍白杆菌(Pseudochrobactrum saccharolyticum,S61)及其复配组合的除氨效果,探索不同除氨菌对堆肥物料腐熟进程的影响。结果表明:发酵结束后,各处理堆肥物料的pH值介于7.58~7.77,含水率下降至17.23%~21.34%;A21、S33复合菌处理的堆肥物料氨气累积释放量最低,有机碳、全氮、全磷、全钾含量分别为36.02%、2.33%、2.28%、0.98%,较不加菌处理分别增加了31.84%、37.06%、6.05%、15.29%,与基础物料中鸡粪相比,堆肥物料有机碳含量降低12.57%,全氮含量增加15.35%。综上所述,假单胞菌和施氏假单胞菌复配,加快堆肥物料腐熟进程,降低物料碳、氮元素损失,提高总养分含量等方面均优于其他单一菌或复合菌处理,可适用于鸡粪堆肥生产实践。
In order to solve the problem of poor ammonia removal effect of single strain on livestock composting,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),Pseudomonas 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 composting 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.
