Fertiliser amendment is the most direct method for improving soil properties of ecologically vulnerable areas (e.g. desertification soil area), and then, understanding the response of microbial community activities and growth to different fertilisation treatments is of great significance in sandy soil restoration. Here, a field experiment with different fertiliser treatments in typical alkaline-sandy soil was conducted. In this study, the difference of physicochemical property, microbial communities and functions in different treatments of no fertiliser (CK), (ii) fly ash chemical fertilisers (CF), (iii) humic straw organic fertiliser (OF), (iv) functional microbial fertiliser (FMF), (v) sulphate-reducing bacterial (SRB) fertiliser (MF) and (vi) humic straw organic fertiliser + functional microbial fertiliser + SRB fertiliser (CMF) were evaluated. The result showed that the contents of soil total organic carbon, NO 3 -N, P and K in the FMF were highest. The abundance of keystone taxa (Gemmatimonadetes and Thaumarchaeota) increased significantly in the treatments of microbial fertiliser. Microbial fertiliser boosted genes for aerobic nitrite oxidation, nitrogen fixation, ammonia oxidation and aromatic compound degradation. The number of methylotrophy and dark sulphur oxidation genes was reduced. The bbove results indicated that the treatments with the inoculation of functional microbes are better than the others for the restoration of alkaline-sandy soil.
