Embodiment 1

[0014]A method for cultivating catfish in a paddy field, during the heading and flowering stage of rice: irrigate the cultivating paddy field to increase the water level of the paddy field by 3 cm, and after irrigating for 2 days, evenly spray the prepared purification regulator into the paddy field at an amount of 60 kg / mu;

[0015]The preparation method of the water purification regulator is as follows: weigh 550 grams of bentonite, grind into powder, add 1.5 times the volume of water, stir for 20 minutes, let stand for 10 hours, filter to obtain a precipitate, and place it in a 90°C oven to dry 6 hours, mix with ultra-fine silica gel with a particle size of 120-130 nanometers in a mass ratio of 35:1.5, add 1.4 times of sulfuric acid with a molar concentration of 1.0 mol / L, and ultrasonically uniformly disperse 30 minutes, soak for 10 hours, filter and wash with water, dry in a 50°C drying oven for 8 hours, place in a reaction kettle, add 1.8 times the volume of ferric hydroxide solu...

Embodiment 2

[0019]A method for cultivating catfish in a paddy field, during the heading and flowering stage of rice: irrigate the cultivating paddy field to increase the water level of the paddy field by 4 cm, and after irrigating for 2 days, evenly spray the prepared purification regulator into the paddy field at an amount of 70 kg / mu;

[0020]The preparation method of the water purification regulator is as follows: weigh 580 grams of bentonite, grind into powder, add 1.7 times the volume of water, stir for 25 minutes, let stand for 12 hours, filter to obtain the precipitate, and place it in an oven at 105°C to dry For 7 hours, mix with ultra-fine silica gel with a particle size of 120-130 nanometers in a mass ratio of 38:1.7, add 1.5 times the volume of sulfuric acid with a molar concentration of 1.1 mol / L, and ultrasonically uniformly disperse 35 minutes, soaked for 14 hours, filtered and washed with water, dried in a 55°C drying oven for 10 hours, placed in a reaction kettle, added 19 times th...

Embodiment 3

[0024]A method for cultivating catfish in a paddy field, during the heading and flowering stage of rice: irrigate the cultivating paddy field to increase the water level of the paddy field by 5 cm, and spray the prepared purification regulator evenly into the paddy field after irrigating for 3 days at an amount of 80 kg / mu;

[0025]The preparation method of the water purification regulator is as follows: weigh 600 grams of bentonite, grind it into powder, add 1.9 times the volume of water, stir for 30 minutes, let stand for 15 hours, filter to obtain the precipitate, and place it in a 120°C oven to dry For 8 hours, mix with ultrafine silica gel with a particle size of 120-130 nanometers in a mass ratio of 40:2.0, add 1.6 times the volume molar concentration of sulfuric acid at 1.2 mol / L, and ultrasonically uniformly disperse 40 minutes, soaked for 18 hours, filtered and washed with water, dried in a 60°C drying oven for 12 hours, placed in the reaction kettle, added 2.0 times the volum...

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...
