摘    要:利用牛粪和稻草为原料进行堆肥实验,通过测定堆肥过程中的温度、含水率等物理、化学指标以及酶活性的变化,研究了接种外源微生物对堆肥过程的影响。结果表明,接种外源微生物比对照提前2d达到高温期,并且维持时间长。大肠杆菌数量及植物毒性比不接种大幅度降低,纤维素酶、脲酶、多酚氧化酶、过氧化氢酶均有所增加。说明接种外源微生物可以使堆肥中微生物数量增多,加速堆料中有机物的分解,加快堆肥腐熟,缩短堆肥反应的进程,对优化堆肥工艺具有重要的意义。

关 键 词:牛粪  堆肥  外源微生物  酶活性

Abstract:The daily increasing of agricultural wastes has posed a huge threat to the environmental safety. The poultry manure may lead to serious environmental pollution if it is not handled properly, for it has such features as higher water content, odorous smell, as well as containing the pathogenic microorganisms. On the other side, if the poultry manure is disposed in a scientific way, the pollution may be controlled, and moreover the wastes may be turned into treasure.Composting is a common technology for dispos...
Keywords:cattle manure  compost  exogenous microbes  enzymic activities
