Description

Technical Field

[0001] The invention belongs to the technical field of turtle breeding, and in particular relates to a device for breeding turtles in rice fields. Background Art

[0002] Soft-shelled turtles like sunshine but are afraid of wind, like quiet but are afraid of being startled, like cleanliness but are afraid of dirt, and like to dig holes and climb. They grow fastest at temperatures of 27-28℃. When the temperature is 18℃, they eat less, and when the temperature is below 15℃, they stop eating completely and hibernate in the mud. In summer, when the temperature exceeds 33℃, they also eat less or stop eating. At this time, they live on the shore day and night and rarely move in the water. Under natural conditions, soft-shelled turtles live in rivers, lakes, ponds, reservoirs and mountain streams in summer, and hibernate at the bottom of the pond in winter. They are more active on quiet, clean and sunny water banks. Soft-shelled turtles mainly eat animal food, but also eat decayed plants and tenderer aquatic plants. They are cold-blooded animals, and their food intake and growth change with changes in water temperature. The conditions in rice fields can meet the growth and development needs of soft-shell turtles. On the one hand, rice fields provide a place for soft-shell turtles to grow. The soft-shell turtles have a large range of activities, feeding, and sunbathing, and they grow and develop quickly, with a high weight gain rate. On the other hand, soft-shell turtles can loosen the soil in rice fields, catch pests, and provide nutrients, which can greatly reduce production costs and improve economic benefits. In addition, a large amount of pond water surface can be saved.

[0003] At present, the method of raising soft-shelled turtles in rice fields is mainly to dig soft-shelled turtle ditches in rice fields, and the digging area is large, accounting for about 20% of the rice fields. On the other hand, since rice fields are open systems that are greatly affected by weather, the depth of soft-shelled turtle ditches is small and is greatly affected by weather, which greatly affects the suitability of soft-shelled turtles' habitats. They are not as stable as lakes and reservoirs and can move up and down with the temperature. When the temperature in rice fields is too high in summer, it is extremely unfavorable for the feeding, growth and survival of soft-shelled turtles, and further improvements are needed. Summary of the invention

[0034] Example 1

[0035] There are about 3 mu of rice fields. According to the technical scheme of a device for raising turtles in rice fields of the above embodiment, the conditions are suitable for raising turtles. Rice field transformation: The rice fields selected for raising turtles are transformed. Ten percent of the rice field area is used to dig a turtle ditch, which is located on one side of a higher ridge or on the side opposite to the drainage outlet of the rice field. The ditch is about 3 meters wide, the deepest water level is about 1.0 meter, and the ditch bottom has a slope from shallow to deep. The turtle ditch has a ridge, and there are several overflow outlets on it, and its height is on the same horizontal plane as the overflow outlet of the ridge. After the device construction and installation of raising turtles in rice fields is completed, the turtle is raised. 35 turtle fry of about 30 grams are raised in each mu of rice fields. When raising, the turtle fry are first surrounded in the turtle ditch for 7 days, and then the fence is withdrawn to allow it to move freely. Feed and manage according to the usual management method. In the early stage of stocking, the temperature is low at night, so the water supply system is turned on to keep the turtle nest warm and moisturized, so that the temperature is maintained at around 20 degrees. In the hot season, when the water temperature in the turtle ditch is close to 32 degrees, the water-gas mixture supply is turned on to keep the water temperature in the turtle nest below 32 degrees. In the rainy season, the air temperature is high, so the gas supply is turned on to keep the air in the nest fresh. The water circulation system is often turned on to keep the water quality indicators in the turtle nest and the turtle ditch good. After 6 months of breeding, the average size of the turtles reached more than one catty, the average survival rate reached 97%, the per mu yield reached 35 catties, the average price was 80 yuan / catty, and the average increase in yield per mu was more than 2,700 yuan.

[0037] There are about 5 mu of rice fields. According to the technical scheme of a device for raising turtles in rice fields of the above embodiment, the conditions are suitable for raising turtles. Rice field transformation: The rice fields selected for raising turtles are transformed. Ten percent of the rice field area is used to dig a turtle ditch, which is located on one side of a higher ridge or on the side opposite to the drainage outlet of the rice field. The ditch is about 3 meters wide, the deepest water level is about 1.0 meter, and the ditch bottom has a slope from shallow to deep. The turtle ditch has a ridge, and there are several overflow outlets on it, and its height is on the same horizontal plane as the overflow outlet of the ridge. After the construction and installation of the device for raising turtles in rice fields is completed, the turtle is raised. 40 turtle fry of about 50 grams are raised per mu of rice fields. When raising, the turtle fry are first surrounded in the turtle ditch for 10 days, and then the fence is withdrawn to allow it to move freely. Feed and manage according to the usual management method. In the early stage of stocking, the temperature is low at night, so the water supply system is turned on to keep the turtle nest warm and moisturized, so that the temperature is maintained above 18 degrees. In the hot season, when the water temperature in the turtle ditch is close to 32 degrees, the water-gas mixture supply is turned on to keep the water temperature in the turtle nest below 32 degrees. In the rainy season, the air temperature is high, so the gas supply is turned on to keep the air in the nest fresh. The water circulation system is often turned on to keep the water quality indicators in the turtle nest and the turtle ditch good. After 6 months of breeding, the average size of the turtles reached 1.2 jin, the average survival rate reached 96%, the yield per mu reached 35 jin, the average price was 80 yuan / jin, and the average increase per mu was more than 3,000 yuan.
