Water quality regulator for fish cultivation in rice fields

Abstract

The invention relates to the technical field of modern agricultural cultivation, and discloses a water quality regulator for fish cultivation in rice fields. The prepared water quality regulator can guarantee the maximum supply of nutrients in the rice growth period by intervening the element content of rice field culture water in the rice growth process, and improve the fish culture environment,and a rice field-fish composite ecological system is constructed, so that the yield and quality of aquatic products are improved, and the rice field water eutrophication problem is solved. By means ofthe culture mode, the whole rice field system has high self-purification capacity, benign growth and reproduction of organisms in water are kept, the water environment is stable, the water changing frequency is remarkably reduced, the cost is reduced, culture losses caused by water quality pollution are avoided at the same time, mutual utilization of rice and aquatic metabolites is achieved, andthe dynamic balance of a rice culture system is realized; and the adverse effects of eutrophication on aquaculture are reduced, the cost investment can also be reduced, the fish culture benefit is improved, and the problems of low quality, poor benefit and large pollution of the aquatic products cultured in the existing rice field are solved.

Description

technical field [0001] The invention belongs to the technical field of modern agriculture and breeding, and in particular relates to a water quality regulator for fish farming in paddy fields. Background technique [0002] Rice field fish farming refers to a production method in which rice and fish are grown in the same paddy field, so that the planting industry and aquaculture industry are skillfully combined. In a similar environment, the rice and fish are symbiotic and mutually beneficial, and a production method is used to improve the overall efficiency of the rice field. . Paddy farming technology plays an important role in improving agricultural production efficiency. At the same time, water pollution is aggravating, and aquatic product quality problems are becoming increasingly prominent. In the actual breeding process, in order to pursue the breeding output, the water pollution has increased, the rice production has decreased, and the quality of aquatic products has...

AI Technical Summary

Problems solved by technology

In the actual breeding process, in order to pursue the breeding output, the pollution of the water body is aggravated, the rice production is reduced, and the quality problems of aquatic products are becoming more and more serious, which restricts the sustainable development of rice field farming.

Aggravated the eutrophication of the water body, and the accumulation of sludge in rice fields was serious, which aggravated the pollution

Seriously affected the healthy development of mixed rice farming

[0003] At present, there are physical, chemical, biological and other methods for the purification of aquaculture water, all of which have high costs, can only be effective for a period of growth, and may cause secondary pollution, low treatment efficiency, and high cost. It does not meet the requirements of ecological and environmental protection, and it is difficult to improve the quality of aquaculture products and the discharge of rice field wastewater.
