Abstract:[Objective]Exploring the effects of scutellaria-residue organic fertilizer on the basic characteristics and microbial community diversity and function of continuous potato soil can provide theoretical references for the resource utilization of Scutellaria-residue and the soil improvement of continuous cropping potato fields. [Methods] Three kinds of organic fertilizer systems were constructed with the bulk medicinal herb Scutellaria-residue and sheep manure (mass ratio 1:4) as the base material, which were 3% of bacterial additive (F1), 5% of bacterial additive (F2), and 10% of bacterial additive (F3). The effects of three Scutellaria-residue organic fertilizer systems on the chemical properties, soil bacterial diversity and community structure of potato surface soils in continuous cropping were analyzed in conjunction with a controlled field trial.[Results](1)Compared with the control group,all three scutellaria-residue organic fertilizer systems significantly increased the available phosphorus and available potassium contents of the soil at the maturity stage by 8.12~12.00 mg.kg-1 and 65.63~88.36 mg.kg-1, respectively;(2) and the total number of bacterial flora in the potato topsoil was increased by 60.96% in both F1 and F2 treatments, 23.19%, and enriched with beneficial genera such as Sphingomonas, Pseudoxanthomonas and Flavobacterium; (3)LEfSe analysis showed that the application of scutellaria-residue organic fertilizers suppressed the absolute abundance of pathogenic bacteria such as Pectobacterium in the soil, and enriched more beneficial bacterial communities with soil carbon and nitrogen cycling functions at significantly higher absolute abundances;(4) the three kinds of scutellaria-residue organic fertilizer systems were able to change the function of the soil bacterial mediated carbon and nitrogen cycle, and increase the soil bacterial flora on the organic matter decomposition potential of soil flora.[Conclusion] The application of scutellaria-residue organic fertilizer can improve the soil available phosphorus and potassium nutrient content, the abundance of beneficial bacterial genera and bacterial functional activity.
