将牛粪与稻草按1:3.5的比例混合堆肥,接种纤维素分解菌、纤维素分解菌+固氮菌。结果表明,与接种纤维素分解菌和不接种的对照处理比较,接种纤维素分解菌+固氮菌的处理堆温上升显著加快、C/N(碳氮比)显著降低、pH在堆肥前期上升快;接种纤维素分解菌的处理比对照堆温上升加快、C/N低。在同时加入纤维素分解菌和固氮菌之后,堆肥过程中C/N明显降低,提高了堆肥的肥效,最大限度的保留了堆肥物料中的氮素营养。
Cow manure and straw by 1: 3.5 ratio compost, inoculation of cellulose decomposing bacteria, cellulose decomposing bacteria + nitrogen-fixing bacteria. The results showed that compared with inoculation of cellulolytic bacteria and non-inoculated control treatment, the temperature increase of Cellulolytic bacteria + Azotobacter significantly increased, C / N (C / N) decreased significantly, pH increased rapidly in the early composting stage ; Cellulolytic bacteria inoculated than the control reactor temperature rise accelerated, C / N low. After adding cellulolytic bacteria and nitrogen-fixing bacteria simultaneously, the C / N ratio of composting decreased obviously, which increased the compost efficiency and retained the maximum nitrogen nutrition in composting materials.
