摘　　要：考察了添加化肥、有机肥、混合肥对水稻-微生物燃料电池产电性能的影响,以不添加肥料的水稻-微生物燃料电池、无植物的土壤微生物燃料电池作为对照,共6组,每组5个平行。研究结果表明,添加有机肥料的实验组产电性能显著高于不添加肥料的对照组,可以达到对照组的1.7倍,然后依次为混合肥料组、不加肥料的对照组,而化肥组的产电性能最差。同时对水稻的生长特征指标进行了测定,发现水稻在土壤肥料适当的情况下生长情况最好,额外加入有机肥并不能让水稻更好地生长,而额外加入化肥则会导致水稻贪青徒长、不成熟不结实等现象。In this study, the effects of chemical fertilizer, organic fertilizer and mixed fertilizer on the electricity production performance and rice growth of rice-microbial fuel cells were investigated. The rice-microbial fuel cells without fertilizer and rice-free soil microbial fuel cells were used as control groups, with 5 replicates in each experimental group. The results showed that the electricity production performance of the experimental group with organic fertilizer was significantly higher than that of the control group without fertilizer, which could be 1.7 times of that of the control group. It was followed in sequence by the mixed fertilizer group, the control group without fertilizer, and the chemical fertilizer group had the worst electricity production performance. At the same time, the characteristics of rice growth were measured. It was found that the rice grew best under the appropriate conditions of soil fertilizer. Additional organic fertilizer could not help rice grow better. Additional chemical fertilizer would also lead to the phenomenon of excessive growing, immature and fruitless rice.
