摘要:
为探究农作物副产品木薯渣对畜禽粪便堆肥过程中氮素保留效果和细菌群落演替的影响。本研究以猪粪和小麦秸秆为堆肥原料，木薯渣为添加剂，设置对照组CK(仅堆肥原料)和处理组CR(堆肥原料添加10%木薯渣)开展为期35 d的实验室规模好氧堆肥研究。结果表明，2组处理均达到腐熟标准，木薯渣的添加有效提高了堆体温度和延长了堆肥高温时间，有助于堆肥的快速腐熟。与对照相比，木薯渣处理堆肥产品的总氮含量和硝态氮含量分别提高了21.87%和39.19%，有效促进了堆肥产物中氮素的保留。测序结果表明，堆肥群落的演替是由不同阶段占优势地位的细菌所主导，堆肥发酵有效削减了大肠埃氏菌-志贺菌属(Escherichia-Shigella)和链球菌属(Streptococcus)等致病菌的相对丰度。功能预测结果显示，代谢是最主要的功能组，细菌通过活跃的代谢活动(主要包括碳水化合物代谢和氨基酸代谢)促进了堆肥有机物料的分解和腐殖化过程。冗余分析结果表明，有机质含量对细菌群落变化的解释率最高(66.30%)，厚壁菌门(Firmicutes)成员对氮素的转化起着关键性作用。综上，堆肥是一个复杂的动态过程，细菌群落的演替受多种环境因素的影响，木薯渣的添加有效改善了堆肥进程，缓解了氮素损失。
