Embodiment 1

[0020] Embodiment 1, paddy field construction, the selection of raising rice field eel, loach paddy field: water quality is fresh and pollution-free, and water yield is abundant, and irrigation and drainage is convenient, and field ridge is solid and leak-proof, and area 2-10 mu, it is better to keep the low-lying paddy field of certain water level, cohesive soil quality . Build field engineering and anti-escape facilities: heighten and widen the field ridge, the height of the field ridge is 50cm, the bottom width is 50cm, and the top width is 40cm. Plastic film or gauze is used as the anti-escape facility on the field ridge. 10cm into the ground. After the paddy field is plowed, a ring ditch with a depth of 30 cm and a width of 20 cm is dug at a distance of 50 cm from the inner side of the field ridge, and the ring ditch is trimmed after transplanting. The inlet and outlet are made of fine-meshed barbed wire or nylon mesh as a fish fence. Dig a "field"-shaped ditch around a...

Embodiment 2

[0021] Embodiment 2 swamp eels, loach are stocked in a suitable place to breed: swamp eels, loach are preferably derived from the original seed field or fished from natural waters, require a healthy body and no disease or injury, age is 2 years old, female body weight 15-25g, male body weight more than 12g. In late February, before the paddy fields are irrigated, 75-100 kg of quicklime per mu is evenly sprayed for cleaning and disinfection. 1,000 kg of fermented pig manure is applied per mu, and the water is filtered into the field. The water depth in the ditch is 30-40 cm, and the water body is fertilized. The transparency of the water is about 25 cm. After the seedlings turn green, put 20,000 to 25,000 rice field eels and loach seedlings with a size of 3-5 grams / tail per mu, soak them in 3% salt solution for 10 minutes before stocking them, and put them into the field after disinfection.

Embodiment 3

[0022]Embodiment 3, feeding and management: (1) water quality management: keep the water quality in the field fresh, add fresh water in good time. After the seedlings are stocked, the depth of water in the paddy field is kept above 5 cm. In the mid-culture period (about mid-July), when it is the high temperature season, the depth of water in the field should be kept above 10 cm. During the breeding period, the water was changed once every 3-5 days. During daily inspections, if eels and loaches are found floating, frightened or still not sinking after sunrise, the water should be changed immediately. (2) Feed management: In order to obtain high yields in paddy field farming eels and loach, in addition to base fertilizer and topdressing, bait should also be cast every day. The feeding amount in the early stage is 1-1.5% of the fish weight, the mid-term feeding amount is 3% of the fish weight, and the later feeding amount is 3-5% of the fish weight. Mainly feed plant bait, such...

Abstract

The present invention provides an environmentally friendly breeding method of ricefield eels and loaches, belonging to the stereoscopic environmentally friendly agriculture development mode and the matching technology. The technical scheme for solving the problem is as follows: 1, rice field construction; 2, rice field fertilization; 3, rational pesticide application; 4, breeding the ricefield eels and the loaches; 5, feeding management; 6, the ricefield eels and the loaches recapturing; 7, escape-proof technology of the ricefield eels and the loaches. The method has the following beneficial effects: 1, the rate of output is high; the annual rate of output of the ricefield eels and the loaches in each area unit is more than 1/3; 2, the management is convenient; the ricefield eels and the loaches can be placed simply, namely, only the seeds need to be placed into the rice field and the earthworms need to be placed on the ridge; 3, the economic benefit is good: the net profit of the ricefield eels and the loaches in the rice field in each area unit can be more than 3000 Yuan; 4, the environmentally protection effect is good, the soil can be loose and the soil fertility can be enhanced; simultaneously, with lots of organic fertilizers, the dosage of the chemical fertilizer is reduced and there is no need for the pesticide such as organic phosphorus.

Description

technical field [0001] The invention belongs to the three-dimensional ecological agriculture development model and supporting technology, and specifically relates to a method for combining ricefield eel and loach with planting and breeding in the farmland. Background technique [0002] Rice field eel is a kind of freshwater fish in temperate zone with strong adaptability, and it is distributed all over our country. Swamp eel is welcomed by people because of its tender and delicious meat and high nutritional value. Together with eel and loach, it is collectively called "three freshwater ginseng". In addition, rice field eel also contains a substance with high value - DHA (docosahexaenoic acid), which is a highly unsaturated fatty acid essential for brain nutrition. necessary substances. Rice field eel not only has high nutritional value, but also has a particularly important role in medicine. According to the "Compendium of Materia Medica": "Swamp eel is sweet, warm and no...
