沼液在甘蔗叶循环利用中的应用研究

摘要

研究了沼液在甘蔗叶循环利用中的应用潜力和途径。在厌氧发酵产沼气实验中，用沼液浸泡长度1～2 cm甘蔗叶5 d的效果最好，沼气总产量为1101．2 L，甲烷含量为57．8％，沼气总产量较对照提高了106．0％。在甘蔗叶快速降解实验中，采用沼液淋洒甘蔗叶＋猪粪复合物料方法的降解效果最好，物料降解率达83．15％，较对照提高了36．7个百分点。%The application potential and approaches of biogas slurry in the cyclic utilization of sugarcane leaves were studied. In the experiment for biogas production through anaerobic fermentation, using biogas slurry to soak 1~2-cm-long sugarcane leaf for 5 days had the best effects:the total yield of biogas reached 1101.2 L, being 106.0%more than that of the control;the content of methane was 57.8%.The results of sugarcane leaf rapid degradation test showed that sprinkling the compound of sugarcane leaf plus pig manure with biogas slurry obtained the best degradation effect, and the degradation rate of materials reached 83.15%, which was 36.7 percent higher than that of the control.
