Fish and vegetable symbiosis ecological planting and breeding method based on breeding tail water

The invention provides a'fish and vegetable symbiosis' ecological planting and breeding method based on breeding tail water, which comprises the following steps: firstly, selecting and preparing a land as a zizania aquatica planting field; secondly, digging stocking ditches, and setting ridges; then, pig breeding tail water is injected to fully soak the soil, and land parcels are raked in a rotating mode to make ridge surfaces flat and ditches neat; the zizania latifolia field is disinfected with quick lime; planting the zizania latifolia; putting fish fries after planting the zizania aquatica; the field management of the fish and vegetable symbiotic system comprises water level adjustment, fertilization, artificial feeding and fish and vegetable disease control; harvesting the zizania latifolia and catching the fishes according to the stocking variety, the stocking time and the fry size. According to the method, utilization of the culture tail water is combined with a soilless culture technology, efficient,
