The invention discloses a fish and vegetable planting and breeding system applied to a two-sided connected greenhouse and suitable for the northern area. The system comprises a fish pond, an edible fungi cultivation frame, a plurality of adjustable siphon drainage gravel coarse filter cultivation tanks, a seepage type gravel fine filter cultivation tank and a water purification pool. According tothe scheme, symbiosis of fish, vegetable and fungi in the fish and vegetable planting and breeding system is realized, the system is particularly suitable for the two-sided connected greenhouse in thenorthern area, water used in each part of the system is recycled, aquaculture wastewater provides fertilizer for a vegetable zone while being purified in the recycling process, waste is changed intowealth, pollution to the water environment due to emission of the aquaculture wastewater is reduced, vegetable yield is increased, vegetable quality is improved, gas balance, temperature balance and energy balance among fish, vegetable and fungi are realized, symbiosis of fish, vegetable and fungi is realized, waste produced by the fish, vegetable and fungi respectively is changed into useful matter for another process, meanwhile, yield of the fish, vegetable and fungi is increased, quality of the fish, vegetable and fungi is improved, waste and pollution of the water resource are greatly reduced, and demands for environmental protection, energy conservation and sustainable development are met very well.
