| 摘 要： | 好氧堆肥是目前有效的羊粪资源化利用方式,本研究旨在探究辅料及微生物菌剂对羊粪好氧堆肥腐熟度的影响。以羊粪、水稻秸秆、菌糠为堆肥原料,加入外源菌剂,检测各个处理的理化指标,生物学指标和重金属指标。平均温度Z4>Z3>Z2>Z1,最高温度68.1℃,69.1℃,69.3℃,71.1℃。pH先升高再降低,堆肥结束为8.53、8.25、8.43、8.35。C/N逐渐降低,堆肥结束为15、16、15和14。含水率逐渐下降,堆肥结束Z2含水率最低并且下降最多,为66.82%。全钾含量逐渐升高,Z4增加最大为196.58%。GI逐渐升高,50天均达到110%,Z4最先达到。NH4+-N含量波动下降。重金属含量均未超过国家标准NY 525—2012。以水稻为辅料与羊粪的堆肥效果优于菌糠,混合菌与菌糠处理提前进入高温期,更有利于羊粪堆体的快速腐熟。

| Abstract: | Aerobic composting is currently the effective recycling way to use sheep manure. This research aims at exploring the effects of the excipients and microbial agents on the maturity of sheep manure aerobic composting. We used sheep manure, rice straw and fungus bran as raw materials, added exogenous inoculants, measured the physical and chemical indicators, biological indicators and heavy metal indicators in each treatment. The average temperature was Z4>Z3>Z2>Z1, the highest temperature was 68.1℃, 69.1℃, 69.3℃ and 71.1℃, respectively. pH increased first and then decreased. At the end of composting, pH was 8.53, 8.25, 8.43 and 8.35, respectively. C/N decreased gradually and was 15, 16, 15 and 14 respectively at the end of composting. The moisture content gradually decreased, and the moisture content of Z2 was the lowest among the four treatments at the end of composting, furthermore the loss rate was the largest which was 66.82%. The total potassium content gradually increased, and the total potassium content of Z4 increased by 196.58%. GI gradually increased, reaching 110% on day 50, Z4 reached it first. The content of NH4+-N decreased with fluctuation. The heavy metal content did not exceed the national standards. The effect of composting sheep manure with rice straw was better than that with fungus bran, and the combination of mixed agents and fungus bran treatment entered the thermophilic stage in advance, reached the maturity rapidly in the sheep manure composting. |
