香蕉茎秆堆肥化处理腐熟度评价研究

Study on Evaluation of Maturity during Banana Stem Composting Treatment

以香蕉茎秆和鸡粪为主要填料进行好氧堆肥,研究了香蕉茎秆堆肥化过程中几种与腐熟度有关的物质含量和参数的变化情况及堆肥腐熟度评价理化指标。研究结果表明,C/N比、阳离子交换量(CEC)、CEC/TOC可以作为香蕉茎秆和鸡粪堆肥化处理腐熟度评价的化学指标,而pH和水溶性有机碳(WSC)不能作为腐熟度评价指标。

An aerobic composting system using banana stem and chicken manure as main stuffing analyses types of material content and parameter variation which are relevant to the maturity, and physical and chemical index of eomposting maturity evaluation during the composting process. The result showed that the C/N ratio, the cation exchange capacity （CEC）, and the CEC/TOC can be a chemical index of the banana stem and chicken manure composting maturity evaluation, but not the water soluble organic carbon（WSC） and pH value.
