摘要:
堆肥逐渐被认为是将禽畜粪便残渣再生为稳定清洁的农产品的好方法。堆肥的质量与堆体微生物酶的活性密切相关。为了更全面的了解堆肥过程及堆肥质量,本文首先研究了堆肥过程中某些理化特性,如总有机碳与总有机氮的比值(C/N),E4/E6 (胡明酸水溶液中光学密度或吸光度分别在465 nm和665 nm处的比值,反应了堆肥物质的芳构化程度)的变化,并分析了这些因素如何影响堆肥的质量;其次重点研究了过氧化氢酶、蔗糖酶酶和纤维素酶活性变化及其对有机物降解作用的重要影响;最后,讨论了这些理化性质和酶活性之间的相关性,从而解释这两者对有机物矿化和腐殖化的相互影响。

Abstract: Composting is increasingly considered a good way for recycling the surplus of manure as a stabilised and sanitised end-product for agriculture, whose quality is much dependent on microbial enzyme activity. In order to comprehensively grasp the composting process and quality, the paper firstly explored the changes of some physic-chemical characters such as C/N ratio and E4/E6 and analyzed how these factors affected its performance. Next, a special attention had been paid to the changes of catalase, invertase and cellulase activities and their important influence on the degradation of organic matter. Then, the correlation between these physic-chemical characteristics and enzymatic activities was discussed whilst interpreted their mutual impact on the mineralization and humification of organic matter.
