Rice and fish combined type circulating gutter channel planting and breeding method and water circulation equipment of rice and fish combined type circulating gutter channel planting and breeding method

Abstract

The invention belongs to the technical field of farming and fishery planting and breeding methods, and particularly relates to a rice and fish combined circulating gutter channel planting and breeding method and water circulation equipment thereof. Rice is planted in the inner circle dam, shrimps, crabs and fishes are bred in the inner circle dam, the oxygen increasing area, the water pushing area, the water flowing groove area and the dirt collecting area are arranged between the inner circle dam and the outer circle dam, water flows, and fishes are cultured in the water flowing groove area, so that the requirements of green and efficient agriculture of rice and fish combination and agriculture and fish combination are met. In addition, the invention further provides a filter screen type water pump assembly which is water circulation equipment needed by the rice and fish combined type circulating gutter channel planting and breeding method, and the filter screen type water pump assembly structurally comprises a water pump, a water pipe, a bottom plate unit, a sewage collection frame unit, an insertion column unit and a rectangular elastic filter screen and is used for pumping sewage into the inner-ring dam or discharging purified water out of the inner-ring dam.

Description

technical field [0001] The invention belongs to the technical field of farming and fishery planting and breeding methods, and in particular relates to a method for planting and raising rice and fish in a combined circulating flow tank, and equipment for water circulation thereof. Background technique [0002] The circulating flow tank refers to a relatively efficient and green fish farming method. In layman's terms, it is to put fish in the tank and use flowing water for breeding, and the flow mode is circular. This culture method is a combination form between pond culture and full flowing water culture, which combines the high efficiency and health characteristics of running water culture, and appropriately reduces the relatively high cost of full flow water culture. [0003] On the other hand, precisely because the entire water body is still fixed, farmed fish is used as a "pollution source", so in the whole cycle process, it is necessary to equip another "purification sou...

AI Technical Summary

Problems solved by technology

[0009] However, when the submersible pump is used alone in the cultivation method of the circulating flow tank, there are two most critical shortcomings of incomplete extraction of fish filth, and foreign matter is easy to be stuck when the purified water is extracted and discharged.
