农业废弃物,如西米废弃物对土壤和水体的污染存在潜在威胁。为了减轻这一问题,本研究对3种不同处理的西米来源的废弃物的堆肥和西米来源的腐植酸的化学性质进行了研究。在大小为61.5×49×33.5cm的白色聚苯乙烯盒子里堆置60d,通过pH、总氮、有机碳、有机质、灰分、阳离子置换能力、磷、腐植酸等指标对其进行分析。所有处理都没有达到高温阶段。与处理T1、T3相比,处理T2(pH、总氮、有机碳、有机质、灰分、阳离子置换能力、磷、腐植酸)质量更好。T2的腐植酸产量也明显比其他两组高。T1和T3的堆肥特性相似。3种处理中的腐植酸化学特性在其他研究者报道的标准范围之内。与处理T1、T3相比,在60d里,T2处理更能有效地生产成熟、高质量的堆肥。
Agricultural wastes, such as sago waste, pose a potential threat to soil and water pollution. In order to alleviate this problem, the present study investigated the composting of three different types of wastes derived from sago and the chemical properties of humic acids derived from sago. The samples were placed in a white polystyrene box measuring 61.5 × 49 × 33.5 cm for 60 days and analyzed by pH, total nitrogen, organic carbon, organic matter, ash, cation exchange capacity, phosphorus and humic acid. All treatments did not reach the high temperature stage. Treatment T2 (pH, total nitrogen, organic carbon, organic matter, ash, cation exchange capacity, phosphorus, humic acid) had better quality than treatment T1 and T3. T2 humic acid production is also significantly higher than the other two groups. The composting characteristics of T1 and T3 are similar. The humic acid chemistry in the three treatments is within the standard range reported by other investigators. Compared to treatments T1 and T3, T2 treatment produced more efficient and mature compost at 60 days.
