摘要:

为明确适合羊粪堆肥腐熟度评价的指标,提高堆肥效率。该研究以湖羊羊粪为原料,采用条垛式人工翻堆堆肥63 d进行堆肥试验,考察了纯羊粪堆肥过程中理化生参数的变化趋势。结果表明:堆肥温度分为升温期(0~1 d),高温期(2~20 d),中温期(21~44 d),稳定期(45~63 d)。温度、干物质得率、有机碳含量、碳氮比、硝态氮、铵态氮、钾速效性、磷速效性等指标在堆肥49 d左右趋于稳定,可作为评价羊粪堆肥是否腐熟稳定的指标。综合各项指标,建议当堆料干物质得率≤78%,或有机碳含量≤38%,或碳氮比≤12.4,或硝态氮≤0.15%,或铵态氮≤0.019%,或钾速效性≤91%,或磷速效性≥73%,或温度进入稳定期时,可认为堆肥已腐熟稳定。腐熟后的堆肥产品容重为0.48 g·mL-1,干物质得率为89.9%。

Abstract:

To clarify the indicators suitable for evaluating the maturity of sheep manure compost and improve composting efficiency, this study used Hu sheep manure as raw material and conducted a 63 day composting experiment using a stack style manual composting method to investigate the changes in physical, chemical, and biological parameters during the composting process of pure sheep manure. The results showed that the composting temperature was divided into a warming period (0-1 day), a high temperature period (2-20 days), a medium temperature period (21-44 days), and a stable period (45-63 days). Temperature, dry matter yield, organic carbon content, carbon nitrogen ratio, nitrate nitrogen, ammonium nitrogen, potassium availability, phosphorus availability and other indicators tend to stabilize around 49 days of composting, which can be used as indicators to evaluate whether sheep manure compost is mature and stable. Based on various indicators, it is recommended that when the dry matter yield of the compost is ≤78%, or the organic carbon content is ≤38%, or the carbon nitrogen ratio is ≤12.4, or the nitrate nitrogen is ≤0.15%, or the ammonium nitrogen is ≤0.019%, or the potassium availability is ≤91%, or the phosphorus availability is ≥73%, or the temperature enters the stable period, it can be considered that the compost has matured and stabilized. The bulk density of the decomposed compost product is 0.48 g·mL-1, and the dry matter yield is 89.9%.
