The influence of three additives including Camellia oleifera meal, C. oleifera seed cake and goat dung during the C. oleifera shell composting was evaluated. The result of physic-chemical parameters indicated that compost of C. oleifera shell with one of additives could achieve the effect of maturity.16S rDNA sequencing suggested that Proteobacteria, Bacteroidetes, Firmicutes, Actinobacteria, Chloroflexi, Tenericutes, Deinococcus-Thermus, Patescibacteria, Fibrobacteres and Acidobacteria were the dominant microorganisms in all compost piles, and their abundances varied with compost additive and composting phase. Goat dung significantly increased the microbial diversity at the mesophilic phase. The microbial composition was most diverse at the end of composting for all piles. No pathogens were detected in the compost products of all three groups, and thus were safe for utilization in plant cultivation. This work considered that compost was best way to address the contamination problem of C. oleifera shell, where goat dung was best additive for compost.
评估了三种添加剂(油茶粕、油茶籽饼和羊粪)在油茶果壳堆肥过程中的影响。理化参数的结果表明,添加一种添加剂的油茶果壳堆肥可以达到成熟的效果。16S rDNA 测序表明,在所有堆肥中,优势微生物为变形菌门、拟杆菌门、厚壁菌门、放线菌门、绿弯菌门、无壁菌门、古菌门、浮霉菌门、纤维杆菌门和酸杆菌门,其丰度随堆肥添加剂和堆肥阶段而变化。羊粪在中温阶段显著增加了微生物多样性。所有堆肥结束时的微生物组成最为多样。在所有三组的堆肥产品中均未检测到病原体,因此可安全用于植物栽培。这项工作认为,堆肥是解决油茶果壳污染问题的最佳方法,而羊粪是堆肥的最佳添加剂。
