One kind of complex system breeding ponds paddy

The present invention relates to a complex system of breeding ponds paddy field, is ecological agriculture farming aquatic BACKGROUND utilization. The complex system includes rice paddies, fish ponds, ditches and strengthen ecological ecology simple ditches. One end side is provided with paddy ponds, ponds and ditches paddy strengthen ecological and with sump, equipped with a simple paddy ecological ditches, with a small simple overflow on ecological ditches, and paddy fields through large overflow sump communication, communicating with simple ponds Eco ditches by pumps. The present invention paddy and fish farming by combination of ecological ditches, fish ponds achieved by paddy water purification and then returned to the ecological cycle ditch water species breeding ponds new model. Solves mainly of rice, there is Shaitian, fertilization, pest control and other rice-fish fish breeding patterns into account the contradictions in the production process, and production is limited, the problem is not easy in large scale.
