摘要
为了提高香蕉废弃茎秆资源的利用效率,以香蕉茎秆为堆肥原料,接种纤维素分解菌,模拟工厂化生产条件,研究其对堆肥的温度变化、有机质分解、微生物数量和粗纤维降解的影响。结果表明,接种纤维素分解菌能提高堆体温度,延长高温时间;能促进堆体中有机物质的分解,有机质含量下降了33.71%;在堆肥初期可以迅速增加堆肥中微生物总数,提高堆肥中微生物种群质量,从而加速堆肥进程;接种纤维素分解菌处理中粗纤维素的总降解率达33.69%,比对照增加了15.58%。
In order to increase the utilization rate of waste banana stalks, the research applied banana stalks as compost feedstock and cellulolytic bacteria as an inoculum under simulated industrial manufacturing circumstances. The effects on the temperature alteration, organic matters decomposition, microorganism number, and coarse fibers degradation were studied. The result indicated that the cellulolytic bacteria not only raised the temperature of compost and prolonged the high temperature phase, but also facilitated the decomposition of organic matters in composting, rendering 33.71% decline of organic content. The inoculum of cellulolytic bacteria could quickly increase the total number of microorganism in early compost and improve the diversity of bacterial community, therefore accelerating the overall composting process. The total degradation rate of coarse fibers reached 33.69% when inoculated with cellulolytic bacteria, which was a 15.58% increase compared to control sample.
