Rice field water quality regulation and control device based on rice field shrimp breeding technology

Abstract

The invention discloses a rice field water quality regulation and control device based on a rice field shrimp breeding technology. The rice field water quality regulation and control device comprises a water pumping box, a detection box, a water filtering system, a control pipe, a water quality treatment system and a drainage box. The water filtering system comprises a water filtering pipe, the water filtering pipe comprises a bottom plate and an arc-shaped plate, first filter screen frames are sequentially and movably installed in the water filtering pipe at equal intervals from left to right, filter screens are arranged in the filter screen frames, filter blocks are movably installed at the adjacent intervals of the filter screens, and the filter blocks are filled with filling blocks. Through movable clamping installation of a bottom plate and an arc-shaped plate, a filter screen frame and a filter screen can be moved by opening the arc-shaped plate after a water filter pipe is used for a long time, agricultural personnel can conveniently and rapidly clean and replace the filter screen frame and the filter screen, and due to the fact that the filter density of the filter screen is sequentially increased from left to right, rice field water is filtered more carefully, and the water quality is improved. By arranging the filter block and the filling block, large impurities in the rice field water are precipitated, and adjustment of the water quality of the rice field water is guaranteed.

Description

technical field [0001] The invention relates to the technical field of paddy field water quality adjustment equipment, in particular to a paddy field water quality control device based on paddy field shrimp farming technology. Background technique [0002] Raising freshwater lobsters in paddy fields is a relatively popular lobster breeding mode. On the basis of the original paddy fields, only a simple transformation is required to breed them, which greatly reduces the threshold for raising lobsters, so it has become popular in recent years. Generally, novices in paddy field breeding can reach an output of 200-300 jin, veteran farmers can reach 300-400 jin, and skilled farmers can reach 500-600 jin. Lobsters can eat fertilized weeds and other aquatic organisms in rice fields, not only saving labor in weeding, but also killing pesky fly larvae. Moreover, shrimps are constantly moving and looking for food in the rice fields, which can not only help the rice fields to loosen so...

Problems solved by technology

[0003] However, raising shrimp in paddy fields requires strict control of water quality to ensure the coexistence of rice and shrimp. The existing methods of adjusting water quality only have simple replenishment of water to balance water quality, which cannot achieve the purpose of better water quality adjustment. As the paddy field water is still water, the quality of the water becomes worse and worse as the shrimp grows, which can easily lead to the death of the shrimp. Due to the high breeding density, a large amount of pollutants will accumulate, including: algae corpses, residual bait, feces, Shrimp shells, dead shrimp, etc. A large amount of pollutants will cause water quality to deteriorate, which is not conducive to the coexistence of rice and shrimp
