s4: a planting base 4 is built, the planting base 4 is built on the side face of the pig house 1, vegetables such as potatoes and the like which are eaten by the pigs are planted in the planting base 4, the pig breeding cost is reduced, the activity range of the pigs is increased, the pigs can be better strengthened through physical consumption, and the meat quality and the taste of the bred pigs are better;

s5: a water circulation system is built, an irrigation pipeline 5 is arranged above a planting base 4, two branches are arranged at the end part of the irrigation pipeline 5, one branch is communicated with a fish pond 2 through a water pump 9, the water pump 9 can convey water in the fish pond 2 to the irrigation pipeline 5 to irrigate the planting base 4, a spray head for irrigation is arranged on the irrigation pipeline 5, water source supply in the planting base 4 is realized through the fish pond 2, and irrigation cost is reduced;

s6: constructing a biogas manure circulating system, wherein the other branch of the irrigation pipeline 5 in S5 is communicated with the fermentation tank 21 through a manure pump 6, and the manure pump 6 can convey biogas manure in the fermentation tank 21 to the irrigation pipeline 5 to fertilize the planting base 4, so that the fertilization cost in the planting base 4 is reduced;

s7: the rainwater utilization system is built, the electric heating plate 28 capable of heating rainwater is arranged in the rainwater cavity 25, the filtering unit 23 capable of filtering rainwater is arranged in the collecting bucket 10, rainwater stored in the rainwater cavity 25 can be heated and boiled by the electric heating plate 28, and can be discharged into the trough 26 through the water conveying pipe 11 after natural cooling to be used for pig drinking water, so that natural resources are reasonably utilized.

In conclusion, the feeding of the whole pig-raising ecological system can be supplied by the houttuynia cordata cultured in a fishpond and vegetables planted in a planting base, the drinking water can be supplied by rainwater, the water supply of the planting base can be supplied by the fishpond, the fertilizer supply of the planting base can be supplied by biogas manure in a biogas pool, fish feed in the fishpond can be supplied by maggots cultured in a septic tank, water in the fishpond can be supplied by groundwater, and the power supply source of electrical equipment of the whole system can be used for power generation and supply by biogas in the biogas pool, so that the whole pig-raising ecological system is formed, and the side-industrial income of fish raising is increased.

It should be understood that the present invention is not limited to the particular embodiments described herein, but is intended to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the invention as defined by the appended claims.
