摘要
评价腐熟度是有关堆肥土地安全利用最重要的问题之一。腐熟度指标可分为三类：物理学指标、化学指标及生物学指标。物理学指标易于检测，常用于描述堆肥过程所处的状态；化学指标得到了广泛研究和应用；堆肥过程是一个生物过程，腐熟度与未腐熟堆肥中植物毒性物质有关，可采用生物学方法进行评价。现在还没有一种公认的堆肥腐熟度指标。采用化学和生物指标综合评价腐熟度是目前最为常用的评价方法。
Evaluation of the maturity of compost is one of the most important problems concerning its safe application to the land. In this paper ,parameters for compost maturity are grouped into three types:physical、chemical and biological indices. Although physical characteristics are simple to be observed ,such observation is only used to describe the composing stage qualitatively. Chemical parameters have been extensively used to assess compost maturity .Because composting is a biochemical process and the compost maturity is related to phytotoxic substances in the immature compost ,it can also be assessed by biological methods . There is not an unanimous parameter to evaluate compost maturity till now.It is common to evaluate compost maturity with chemical and biological parameters together.
