Main Data : Biofertilizer application was a sustainable and environment friendly method to improve soil fertility. However, the complexity of soil and environment makes it difficult for microbial colonization and increase the uncertainties of biofertilizer application. Thus, further understanding of the resistance from resident community, invasiveness of biofertilizer and assemble process of soil community is necessary to improve the effectiveness of biofertilizers. Here, three potassium solubilizing biofertilizers with similar function but different similarity with resident soil community (including phylogenetic distance, community composition and diversity) were introduced to field soil at Yongan, Hunan Province, China. The results showed that potassium solubilizing efficiency, structure and composition of soil bacterial community were affected by biofertilizer introductions. Among the three tested biofertilizers, DW had the highest similarity with CK, and the shifts of community structure, composition and network structure in FDW were greater from CK than FCY and FDS. However, the potassium solubilizing efficiency of FDW was lowest among three treatments, which was different from the community shifts. This demonstrated that the similarity between invader-resident communities would affect the resistance from resident community and the chance for alien species to occupy ecological niche, and then affect the invasion effect. Finally, higher community similarity with resident community would make biofertilizer face more intensely resistance and make the potassium solubilizing species in biofertilizer more difficult to spread and grow in new habitat although more species could successful colonization. These results highlight the importance of considering similarity between invader-resident community on the microbial invasion, and provide a potential and economically way to promote the sustainable development of agriculture.
