Abstract: Lead zirconate titanate (PZT) has been widely used because of its electrochemical effect, but its effect on soil microorganisms is rarely studied. In this study, laboratory soil microcosms with different soil moisture content and pH were established to explore the effects of the PZT-5H bimorph with different quantities and states on soil microorganisms after 49 days. Plate counting was used to study the number changes of soil bacteria, fungi and actinomycetes. Isothermal microcalorimetry was used to evaluate microbial activity. High-throughput sequencing was used to analyze soil microbial diversity and community structure. The results showed that the number and activity of microorganisms could be significantly promoted by two vibrating PZT bimorphs under the appropriate soil moisture content (20%) and pH (7). At the same time, it promoted the growth of non- dominant microorganisms and increased the diversity of microorganisms. These results indicate that it is possible for PZT bimorphs to be used in soil field.
