Method for cultivating catfish in rice field

Abstract

The invention relates to the technical field of modern agricultural cultivation, and discloses a method for cultivating catfish in a rice field. The method ensures the maximum supply of nutrition in the rice growth period by intervening the element content of rice field cultivation water in the rice growth process, improves the catfish cultivation environment, and promotes the preferred growth ofthe catfish, thereby enhancing the yield and quality of the catfish. By means of the cultivation mode, a whole rice field system has high self-purification capacity, benign growth and reproduction oforganisms in water are kept, the water environment is stable, the water changing frequency is remarkably reduced, the cost is reduced, meanwhile, cultivation losses caused by water quality pollution are avoided, mutual utilization of metabolites of rice and catfish is achieved, and the dynamic balance of a rice culture system is realized; and adverse effects of eutrophication on catfish cultivation are reduced, cost investment can be reduced, catfish cultivation benefits are increased, the problems of low catfish quality, poor benefits and large pollution in existing rice field cultivation aresolved, and the yield can be increased on the premise that catfish cultivation quality is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of modern agricultural breeding, and in particular relates to a method for cultivating catfish in paddy fields. Background technique [0002] Catfish mainly live in the middle and lower layers of rivers, lakes, reservoirs, and pits. They mostly move along the coast. During the day, they hide under grass, stones or deep water, and they forage frequently at night. After autumn, it lives in deep water or mud for overwintering, and its feeding level is also weakened. Carnivorous fish, prey mostly on small fish, such as meal strips, crucian carp, goby, wheat ear fish, carp, loach, etc., and also eat shrimp and aquatic insects. Mainly for swallowing, the role of teeth is mainly to prevent food from escaping. It is a nocturnal animal and hides quietly in pits at the bottom of rivers or under tree roots during the day. Eats a lot, large species such as the Danube catfish will attack small water birds or mice, bot...

Problems solved by technology

However, in the actual breeding process, in order to pursue the breeding output, the pollution of the water body has increased, the rice production has decreased, and the quality of aquatic products has become increasingly prominent, 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
