Running-water circulation fish culture ecological system in rice field

Abstract

The invention relates to the technical field of fish culture ecological systems in rice fields, in particular to a running-water circulation fish culture ecological system in a rice field. The systemcomprises the rice field and a fish pond, a ridge is arranged between the rice field and the fish pond, and ditches are formed around the rice field; the bottom of the fish pond is in an inclined shape, a collector is arranged at the lower end of the bottom, and the bottom of the collector is communicated with the bottom of one end of each ditch; the other end of each ditch is connected with the fish pond and provided with a micropore aerator. The fish pond is separated from the rice field, the ditches are used for discharging fish excrement in the fish pond into the rice field, water in the fish pond is kept clean, the fish excrement can be used as organic fertilizer and help rice seedlings to grow up at the same time, and rice and fish schools have mutual benefits, coexist and grow up; circulation development of resources is achieved, the utilization rate is high, the rice ripens and is harvested, fish feeding cannot be influenced, fry can be put anytime, and fry putting cannot be influenced by growth time of the rice.

Description

Technical field

[0001] The invention relates to the technical field of a rice field fish farming ecosystem, in particular to a rice field circulating water fish farming ecosystem. Background technique

[0002] The rice field fish culture model is an ecological planting system in which rice and fish are symbiotic, interdependent, and mutually promoted. However, the existing rice field fish culture models mostly raise fish directly in the rice field. Large restrictions. When the rice is harvested, the survival and growth time of the fish will also be greatly restricted, the fish breeding density is also limited, and the role of fish manure cannot be fully utilized and utilized, resulting in a large amount of nutrition Material is wasted. At the same time, if there are too many fish, excessive accumulation of manure will seriously affect the growth of rice seedlings in the rice field, greatly reducing the growth and development of rice seedlings, and the effectiveness and economy ar...
