We investigated the effects of the aggregate spray-seeding (ASS) technique on soil bacterial community diversity, life strategies, and seasonal change. Soil from six plots with original vegetation (CK, n=6) was compared to soil from 15 plots with spray-seeding restoration (SR, n=15) using environmental DNA sequencing. The bacterial Shannon and Chao1 indices of SR soils were significantly greater (P<0.05) than those of CK soils. The Chao1 index for the SR soil bacterial community was significantly greater in summer (P<0.05) than in winter. The ratio of the relative abundance of bacterial K-strategists to r-strategists (K/r) and the DNA guanine-cytosine (GC) content in the SR soil were significantly lower (P<0.05) than those in the CK soil. Principal coordinate analysis revealed significant differences between the SR and CK bacterial communities. The GC content was positively correlated with the K/r ratio. Soil conductivity was negatively associated with the K/r ratio and GC content, indicating that ionic nutrients were closely related to bacterial life strategies. The ASS technique improved soil bacterial diversity, altered community composition, and favored bacterial r-strategists.
