Fish and vegetable planting and breeding system and method applied to two-sided connected greenhouse and suitable for northern area

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of three-dimensional breeding, and specifically relates to a double-sided conjoined greenhouse fish and vegetable planting system suitable for northern regions, especially for fish, vegetables and vegetables under the conditions of east-west and north-south double-sided conjoined greenhouses in cold northern regions. Edible fungus and other planting and breeding combination mode. Background technique [0002] The winter in the northern region is cold and dry, and the outdoors are covered with ice and snow for half a year. Vegetable planting and aquaculture under natural conditions cannot be realized. Therefore, various greenhouses have emerged as the times require. Among them, there is an east-west conjoined greenhouse with north and south sides that is widely used, but the temperature and light difference between the north and south sides of the greenhouse are very different, which is difficult to control, ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a double-sided conjoined greenhouse fish and vegetable planting system suitable for the northern region, so as to solve the problem of the large temperature and light gap between the north and the south of the north-south double-sided conjoined greenhouse in the northern region, which is difficult to control, and the use efficiency is not high. , low economic benefits, serious waste of resources and other practical problems, to achieve the purpose of increasing income and energy saving in facility agriculture
