病虫害生态调控机理与应用技术研发进展OA

Ecological regulation of crop pests and diseases,is a green control approach based on farmland landscape reconstruction,with the goal of continuously enhancing natural pest suppression capacity.Drawing on the progress of the National Key R & D Program project"Research on Ecological Regulation Mechanisms and Application Technologies for Crop Pests and Diseases(2023YFD1400800)",this paper briefly reviews advances in ecological regulation theory,functional plant deployment,crop and cultivar diversity regulation,regional landscape design,and the industrialization of ecological agricultural products.The project proposed the concept of"agroecological service stations",upgrading non-crop habitats such as field margins,ditches,farm roads,irrigation zones,and functional plant strips into designable,constructible,and assessable farmland ecological infrastructure.Application results show that by reforming the ecological environment of pests and diseases,enhancing natural enemy control,shaping crop defense phenotypes,and interrupting pathogen transmission,pest and disease risks can be reduced while decreasing dependence on chemical pesticides,thereby promoting the transformation of pest and disease management from single-target control to regional ecosystem-based management.
