Fish and vegetable symbiotic planting and breeding method

The invention relates to the technical field of fishery breeding, in particular to an ecological fish and vegetable symbiotic planting and breeding method for fish breeding without water change and vegetable planting without fertilization, which comprises the steps of pond disinfection, water quality cultivation, fingerling stocking, feeding management, water quality management, aquatic plant cultivation, facility escape prevention, fish disease control and daily management. The water quality and the growth and activity conditions of the snakehead are observed, and the feed and the water quality are adjusted in time according to different growth stages and conditions. Aquaculture and vegetable planting are organically combined, the overall construction cost is low, the preparation area is small, the utilization rate of the culture area is increased, the labor cost and the time cost are greatly reduced, management is simple and efficient, labor and time are saved, the water quality of the pond is improved, and
