The three-dimensional planting and breeding technology of paddy field has become a high-efficiency ecological agriculture model, which provides an effective way for the sustainable development of the agricultural industry and the increase of farmers' income. Carrying out standardized research on three-dimensional planting and breeding technology in paddy fields can improve the comprehensive utilization rate of farmland and water resources, save input costs, and help achieve the goal of green, high-quality, high-yield and efficient agricultural development. However, up to now, the planting and breeding model is not perfect in technology, which greatly limits the effective promotion of this model. Based on superior ecological environment and climate conditions of Longyan City, a set of the three-dimensional planting and breeding technology of paddy field suitable for the development of Longyan area was put forward according to local conditions in this study. The economic benefits and techniques of“rice-fish-loach”“rice-fish-soft shelled turtle”“rice-duck” model were systematically analyzed and reported, which will provide a reference for the application of this technology in Longyan and similar area and be conducive to the promotion and development of the ecological three-dimensional planting and breeding model of paddy field.
