| 摘 要： | 试验以玉米秸秆为材料,采用静态培养方法,对添加过不同浓度纳米银溶液的玉米秸秆腐解过程中元素和物质成分含量的变化进行了分析,研究纳米银对秸秆腐烂的影响。结果表明,与对照相比,添加纳米银溶液的处理碳元素和木质纤维素含量降低的速率明显减缓,氮元素含量升高速率显著降低,说明纳米银对环境中的微生物具有明显的抑制作用,纳米银在防止秸秆腐烂方面具有重要作用。

| Abstract: | Take corn straw as experiment materials,a static cultivation experiment was carried out to investigate the effect of nano-silver on straw decomposition.The effects of nano-silver at different concentra-tions on the elements and material ingredients changes of corn straw during the decomposition were studied.Comparing with the control,reducing rates of C element content and lignocellulose content were significantly slowed down,increasing rates of N element content were obviously decreased.The results showed ... |
