In order to explore the effects of bacteria on the decomposition processes and water environmental conditions, we used litter bag method and compare reed litter decomposition rates under different Bacillus subtilis addition treatments. Neither mesh size nor bacterial treatment have significant effects on the decomposition rates in the earlier phase. But in last three retrieves, the decomposition rates of litter bags with Bacillus subtilis addition were significantly (p = 0.012) higher than that without Bacillus subtilis addition treatment. As for bacterial influence water parameters, aquatic environmental markers ammonia-nitrogen (NH₃-N), total phosphorus (TP), dissolved oxygen (DO), and chemical oxygen demand (COD) didn't show significant difference between different Bacillus subtilis addition treatments. The decomposition rates were affected by litter quality and water parameters. Furthermore, the N/P and C/P ratios of litter were good predictors for litter decomposition. Our findings suggested that the bacterial inoculation could be an excellent approach to facilitate the decomposition processes and nutrient cycles in the wetland ecosystems, but it might require more than 45 days to see the positive effects.

为了探索细菌对分解过程和水环境条件的影响，我们采用垃圾袋法，比较了不同枯草芽孢杆菌添加处理下芦苇凋落物的分解速率。筛孔尺寸和细菌处理均未对早期分解速率产生重大影响。但是在最近的三次检索中，添加枯草芽孢杆菌的垃圾袋的分解率显着 高于未添加枯草芽孢杆菌处理的垃圾袋（p = 0.012）。至于细菌的影响水参数，水生环境标志物氨氮（NH ₃-N），总磷（TP），溶解氧（DO）和化学需氧量（COD）在不同枯草芽孢杆菌添加处理之间没有显着差异。分解速率受垫料质量和水参数的影响。此外，垫料的N / P和C / P比是垫料分解的良好预测指标。我们的发现表明，细菌接种可能是促进湿地生态系统中分解过程和养分循环的极好方法，但可能需要超过45天才能看到积极的影响。
