微生物发酵床垫料酶活性变化研究

摘要

This experimentation was conducted at the National Modern Agricultural Demonstration Area in Fuqing, Fujian on January 26,2015. Activities of invertase,cellulase,hemicellulase,and neutral and alkaline phosphatase were detected in 0 - 50 cm layers of the bedding material at the piggery.The activities of all of the enzymes significantly decreased gradually from the surface to 50 cm in depth of the bedding.The information provided for further study on the mechanism and process of the microbial fermentation relating to the pig-on-litter system.%于福建省福清市国家现代农业示范园的微生物发酵床养猪栏内采集0～50 cm 垫料层样品，对微生物发酵床不同方位及不同深度垫料进行酶活性研究，测定其蔗糖酶、纤维素酶、半纤维素酶、中性与碱性磷酸酶，探讨酶活性变化规律。结果表明：在0～50 cm 的垂直深度，随着深度的加大，酶活性显著下降，为微生物发酵床作用机理及垫料发酵程度提供理论参考。
