ABSTRACT=<p>The fermentation quality and microbial diversity of king grass (K), cassava foliage (C), and <italic>Broussonetia papyrifera</italic> (B) ensiled in the absence of an inoculant (K, C, B) or the presence of <italic>Lactobacillus plantarum</italic> (KL, CL, BL) for 60 days were investigated. The bacterial community was characterized by using the 16S rDNA sequencing technology. The relative abundance of <italic>Lactobacillus</italic> in K was very high, and it decreased after adding <italic>L. plantarum</italic> while <italic>Acinetobacter</italic> increased to some extent. The relative abundance of <italic>Lactobacillus</italic> in group C was also very high, and the inoculant <italic>L. plantarum</italic> enriched it in the CL group. As the second dominant genus of group C, the relative abundance of <italic>Pseudomonas</italic> decreased significantly in CL. <italic>Weissella</italic> and <italic>Enterobacter</italic> were the dominant genera in B and BL, and the relative abundance of <italic>Lactobacillus</italic> decreased in BL. For K, C, and B, the inoculant <italic>L. plantarum</italic> decreased the pH value and NH<sub>3</sub>-N content markedly, inhibited the production of butyric acid, increased the content of lactic acid, and significantly improved the fermentation quality. In conclusion, <italic>L. plantarum</italic> affected the bacterial community of C and improved the silage quality of K, C, and B to a certain extent.</p>
